What is the job?ย
No matter how powerful and flexible you build a platform, at the end of the day itโs the experience you can give the user that matters.ย Radix is seeking a savvy frontend development expert to help build the tools that will define the future of decentralized finance (DeFi) and Web3.0 user experience.
DeFi and Web3.0 have turned out to be the killer apps that are taking public distributed ledgers from niche products for speculators and hobbyists to projects of global economic significance, and with them have come a new paradigm for user interfaces.ย Authentication models, interoperability expectations, and the entire concept of user accounts are all undergoing dramatic changes; at Radix youโll have the opportunity to define the way forward while working at the very cutting edge of a space undergoing furious growth.
Your initial focus will be development of full-stack typescript applications and integrated backend services spanning web and mobile devices that get users, their identity, and their assets connected to DeFi and Web3.0 applications on the Radix network. Working from Figma prototypes and pre-defined network APIs you will work within our Core Apps team to build and maintain web applications that interact with our unique mobile app, backend infrastructure to connect web and mobile experiences, and SDKs and technologies that developers will use to create their own web applications that interact with our mobile app.
What are we looking for?ย
Youโre a confident coder who likes to work at the user interface level, and you have built public-facing websites or applications in Typescript in the past.
Youโre a generalist, and have experience building REST services and/or WebSocket backends.
You are a researcher and enjoy requirements engineering for SDK development.ย
You like to actively shape designs and play with ideas as you build, and are comfortable iterating until it feels just right.
Youโre able to isolate the 90% case for user experiences.ย ย
You think in terms of making the most common interactions effortless, rather than making anything possible.
Youโre intelligent and learn quickly.ย Absolutely no one at Radix winds up only doing whatโs in their job description, and adaptability is essential.
What do you need?
4+ years as a professional software engineer in full-stack development
You are fluent in Typescript.
You haveย SDK development experience.
You know how to work with complex APIโs (ideally WebRTC, WebAuthn, etc)
You excel at researching and requirements gathering.
Youโre enthusiastic about working in a multidisciplinary team with mobile engineers.ย
Who are we?ย
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 $200ย 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 solutionโthe first layer-one protocol built specifically for mainstream DeFiโand 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.ย ย
Alternatively, if you feel like you donโt 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 wouldnโt 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!ย
