About Heliax

Heliax is a public goods lab which researches, develops, deploys, and maintains open-source protocols and mechanisms designed to serve the everyday needs of humanity. Using these protocols and mechanisms, we build vertically integrated products and networks that form coherent open systems which are capable of acting as an alternative to existing exploitative paradigms.

Two of the most notable vertically integrated protocols are Anoma and Namada. 

Anoma is an intent-centric, privacy-preserving protocol for decentralized counterparty discovery, distributed solving,and atomic multi-chain settlement – a radically novel architecture for decentralized protocols marking the beginning of the third generation of architectures ever since programmable settlement.

Namada is Anoma’s first fractal instance. It is proof-of-stake Layer 1 protocol for asset-agnostic, interchain privacy. The key innovations include ZCash-like shielded transfers for any assets (fungible and non-fungible), incentivised privacy sets, and interoperability with Ethereum via a custom bridge and IBC.

What is the job?

Looking for challenging responsibilities in the most promising tech industry? Join us as the first QA Automation Engineer (in this particular product team) in the crypto financial industry, and you will get the most out of using new technologies and test methods.

You will accelerate your career and constantly improve technically by tackling these issues and being able to utilize the personal £2000/year budget for learning & development.

You will challenge all user scenarios and test cases to investigate all possibilities of failure across a range of Web apps, and API applications. You will make sure that happy path scenarios function as advertised, and that a massive array of potential error conditions all fail gracefully, predictably and in a meaningful way to end users. 

During your first few months, you will start by defining the tools and frameworks required to have a complete suite of automated tests. This will involve diving into the applications features and functionality, rolling up your sleeves doing manual testing. With a better understanding under your belt, you will define test plans that can be  automated and cover UI and API testing, as well as testing failures in any of the subsystems, including databases, third-party services or other internal services.

What are we looking for?

• You enjoy automating everything, the thought of repeating tasks manually makes you shiver, but you understand the need to do exploratory manual testing to create test plans.

• You have experience testing Web apps, APIs applications in a fast delivering growth environment.

• You are a hands-on, independent product tester with experience working in a multidisciplinary team formed of designers, Front and Backend developers and DevOps.

• You’re patient when dealing with others. You’re a good listener, and happy to be a teacher when needed.

What skills do you need?

• You have solid demonstrable experience as a QA Automation Engineer doing end-to-end testing.

• You love breaking things and let your creativity go wild (e.g. functional and black-box testing, regression testing, system integration testing, load testing, manual testing).

• You are proficient in at least one programming/scripting language such as Python, C#, Java or JavaScript.

• Experience with BDD, TDD, or contract testing.

• Docker and Git experience is important.

• You have good knowledge and understanding of CI/CD cycles and integration test automation with CI/CD.

Who are we? 

At RDX Works, we’re a team of like-minded thinkers who have long been convinced that we’re living in the earliest stages of a global financial revolution. This revolution is being fuelled by decentralized finance (or DeFi for short), which is enabling an assortment of pioneering developers and entrepreneurs to re-invent almost every financial product that is currently traded and invested in traditional markets, without requiring central authorities or siloed infrastructure. DeFi has captured a great deal of attention and investment in the crypto-aware niche, growing assets under management from $1 billion to over $200  billion in a few years. Impressive as its growth has been, its current market size isn’t even a rounding error on the over $400 trillion held in traditional finance. We’re focused on what it will take to go from billions to trillions.

RDX went back to first principles to come up with the right technical solution—the first layer-one protocol built specifically for mainstream DeFi—and we have already tested out at over 1 million transactions per second. We’re keenly aware that the need for an infinitely scalable platform is only one prerequisite among many for mass adoption, and we’re also blazing new ground in the areas of purpose-built developer tools, user experiences, and regulatory integration.

We have forged a path deep into the future of what distributed ledger technology is going to look like and we need you to come and be part of the team that is making that happen right now.

If this job sounds like it was made for you, then please apply directly via the link or email [email protected] for more information.

Alternatively, if you feel like you don’t match all of the requirements, we would love you to still apply anyway. We understand that confidence gaps and imposter syndrome can get in the way of meeting incredible candidates and we wouldn’t want this to prevent us from meeting you; especially as we are big advocates of helping people learn & grow. This is also another reason we do not advertise salaries, we want to keep it as even a playing field as possible!

Salary and compensation

Location

What is the job?

As a senior Rust software engineer at RDX Works, you will join a team of distributed systems engineers working to bring our smart contract functionality, Scrypto, to the Radix public network. Scrypto is a RDX-created framework and extension to the Rust programming language to enable the rapid and safe development of decentralized financial applications (dApps) that will power the future of DeFi into the mainstream. At RDX, we love Rust. Our smart-contract capability, Scrypto, is Rust-based, the new v2 Radix Engine is built from the ground-up in Rust, and we’re looking to extend its use to the code that runs the Radix Network. This is where we need your help.

When you join us, you will first come up to speed by aiding in the migration of part of the existing codebase from Java to Rust. Building upon this knowledge, you will venture into new territory, solving the challenges ahead to bring programmability to the Radix public network. From this point forward you will be making new ground right at the cutting edge of a rapidly evolving branch of computer science, as we embark on a journey towards a novel, massively sharded release which will enable unlimited scale.

Your days will be filled with hard, interesting problems - thinking through all the ways things can go wrong and coming up with solutions which are both elegant and practical - and then turning these into code. You will be tackling synchronization, consensus and networking problems that often have no perfect answer. You will meddle with dark powers best left untouched, learn more about decentralized systems than you dreamed was possible, and work with an inspiring team of incredible people. You will make your mother proud, even if you’re never quite able to properly explain to her what it is you built.

What are we looking for?

• You are a prolific, confident coder, and are persistent in working problems to resolution
• You possess strong attention to detail, and are rarely surprised by unconsidered edge cases
• You’ve used generic types so much that the angle bracket keys on your keyboard are beginning to wear away
• You are unafraid of working in a space where there is little prior art to refer to
• You have done and like to do demonstrably hard things
• You enjoy talking through tough problems with smart people, and are happy to accept ideas and approaches that you didn’t personally come up with
• You are someone who started to learn Rust for fun and now have several years of experience under your belt
• You are able to explain hard concepts in a clear and concise manner

What do you need?

• Bachelor’s degree in Computer Science, Mathematics or similar
• Solid commercial experience working as a Software Developer
• Fluent in Rust and comfortable reading Java
• Completely comfortable with asynchronous programming models

Some of the following experience will help you stand out:

• Noddingly familiar with the practical aspects of asymmetric cryptography and zero-knowledge proofs, and having an understanding of the underlying theoretical foundations
• First-hand experience working with large data sets and dealing with complex distributed systems, and are all too familiar with the attendant complications and gremlins that emerge once not-perfectly-reliable things start talking to each other over a not-perfectly-reliable network
• Experience with or knowledge of authenticated data structures
• Hands-on experience with big data tools such as Hadoop, Cassandra etc
• Experience with blockchain/DLT development
• Have a background in computer science or a scientific qualification with demonstrable experience in consensus
• Experience implementing a BFT-style consensus protocol

What is the job?

As a distributed systems engineer at RDX Works, you get to do all the fun stuff. No turning reams of procedural business logic into code for you! Your days will be filled with hard, interesting problems - thinking through all the ways things can go wrong and coming up with solutions which are both elegant and practical - and then turning these into code. You will be tackling synchronization, consensus and networking problems that often have no perfect answer. You will meddle with dark powers best left untouched, learn more about decentralized systems than you dreamed was possible, and work with an inspiring team of incredible people. You will make your mother proud, even if you’re never quite able to properly explain to her what it is you built!

You will first come up to speed by aiding in the delivery of some new improvements to our distributed public ledger. Building upon this knowledge, you will venture into new territory, solving the challenges ahead to bring programmability to the Radix public network in our next major release. From this point forward you will be making new ground right at the cutting edge of a rapidly evolving branch of computer science, as we embark on a journey towards a novel, massively sharded release which will enable unlimited scale.

What are we looking for?

• You are a prolific, confident coder, and are persistent in working problems to resolution.
• You possess strong attention to detail, and are rarely surprised by unconsidered edge cases.
• You’ve used generic types so much that the angle bracket keys on your keyboard are beginning to wear away
• You are unafraid of working in a space where there is little prior art to refer to
• You have done and like to do demonstrably hard things
• You enjoy talking through tough problems with smart people, and are happy to accept ideas and approaches that you didn’t personally come up with

What do you need?

• Bachelor’s degree in Computer Science or equivalent
• 5+ years working as a professional software developer
• Fluent in Java or Rust (Java and Rust is what you’ll be using here)
• Completely comfortable with asynchronous programming models

Some of the following experience will help you stand out:

• Noddingly familiar with the practical aspects of asymmetric cryptography and zero-knowledge proofs, and having an understanding of the underlying theoretical foundations
• First-hand experience working with large data sets and dealing with complex distributed systems, and are all too familiar with the attendant complications and gremlins that emerge once not-perfectly-reliable things start talking to each other over a not-perfectly-reliable network
• Experience with or knowledge of authenticated data structures
• Hands on experience with big data tools such as Hadoop, Cassandra etc
• Experience with blockchain/DLT development
• Have a background in computer science or a scientific qualification with demonstrable experience in consensus
• Experience implementing a BFT-style consensus protocol

Who are we?

At RDX Works, we're a team of like-minded thinkers who have long been convinced that we're living in the earliest stages of a global financial revolution. This revolution is being fuelled by decentralized finance (or DeFi for short), which is enabling an assortment of pioneering developers and entrepreneurs to re-invent almost every financial product that is currently traded and invested in traditional markets, without requiring central authorities or siloed infrastructure. DeFi has captured a great deal of attention and investment in the crypto-aware niche, growing assets under management from $1 billion to over $200 billion in a few years. Impressive as its growth has been, its current market size isn't even a rounding error on the over $400 trillion held in traditional finance. We're focused on what it will take to go from billions to trillions.

RDX went back to first principles to come up with the right technical solution—the first layer-one protocol built specifically for mainstream DeFi—and we have already tested out at over 1 million transactions per second. We're keenly aware that the need for an infinitely scalable platform is only one prerequisite among many for mass adoption, and we're also blazing new ground in the areas of purpose-built developer tools, user experiences, and regulatory integration.

We have forged a path deep into the future of what distributed ledger technology is going to look like and we need you to come and be part of the team that is making that happen right now.

What is the job?

No matter how powerful and flexible you build a platform, at the end of the day it’s the tools and services you present to the user that define the experience. Radix is seeking a veteran, .NET developer to build the systems that will define the future of decentralized finance (DeFi).

DeFi has turned out to be the killer app that is taking public distributed ledgers from niche products for speculators and hobbyists to projects of global economic significance, and with it has come a new paradigm for user experiences. Authentication models, interoperability expectations, and the entire concept of user accounts are all undergoing dramatic changes; at Radix you’ll have the opportunity to define the way forward while working at the very cutting edge of a space undergoing furious growth

Working from a coherent vision, step by step you will turn requirements into top-notch products working with ace developers and testers through rapid cycles of implementation, feedback gathering, and tuning to produce delightful results. You will come face to face with all the nuances and complexities of asynchronous processing of payment transactions. No architectural decision will be made without your participation. Constant challenges will become an integral part of your working day and boring coding will remain a scary memory.

About you

• You are adept at going from problem statements to solution design, and then breaking that high level design down into discrete segments of useful work.
• You have a good instinctual feel for the complexity of a development problem, and can quickly determine which things will be risky/challenging and which should be straightforward.
• Once you understand a system concept, you are able to identify the highest value area to work on next. You can work towards a desired end state and come up with your own tasks to achieve it along the way.
• You have released and maintained consumer-facing things in the past; your history is not limited to internal business applications or implement-and-handoff contracting engagements.
• You are a high output developer. You make rapid progress when building out systems.
• You’re intelligent and learn quickly. Absolutely no one at Radix winds up only doing what’s in their job description, and adaptability is essential.

What do you need?

• 5+ years as a professional software engineer
• Fluent in C#/.NET
• Comfortable at any place in the tech stack above the OS level
• Familiarity with the current crypto ecosystem is a plus, but not required. When you’re here, you’ll learn a ton about it either way!
