When applying for jobs, you should NEVER have to pay to apply. You should also NEVER have to pay to buy equipment which they then pay you back for later. Also never pay for trainings you have to do. Those are scams! NEVER PAY FOR ANYTHING! Posts that link to pages with "how to work online" are also scams. Don't use them or pay for them. Also always verify you're actually talking to the company in the job post and not an imposter. A good idea is to check the domain name for the site/email and see if it's the actual company's main domain name. Scams in remote work are rampant, be careful! Read more to avoid scams. When clicking on the button to apply above, you will leave Remote OK and go to the job application page for that company outside this site. Remote OK accepts no liability or responsibility as a consequence of any reliance upon information on there (external sites) or here.

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 if you don’t have an up to date CV to apply with, contact [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!

Solidity Developer Role district0x is a global organization developing the next generation of decentralized applications (dApps). Built using Ethereum, Snapshot, and IPFS, district0x is a network of marketplace dApps known as districts. Our mission is to decentralize the ownership structure of the world's marketplace by providing a platform for the creation, operation, and governance of peer-to-peer marketplaces.
Summary of Position: The district0x tech stack is driven in the backend by smart contracts developed in Solidity and deployed to the Ethereum blockchain, and in the front end by Clojurescript, React, and Re-frame served via the Interplanetary File System and a Clojure server linked via GraphQL.
As a Solidity Developer, your primary goal is to build front end interfaces for new districts and extend libraries to serve user-made districts. The secondary goal is to create new and secure services written in Solidity, and develop automated test cases for these services. Solidity Developers should work independently when building, but must collaborate with other developers in order to check each other's work and maintain the highest standards of code quality. A great Solidity Developer will go above and beyond by building new and unique user experiences, and automating any routines for the business at large.
Responsibilities
Key Responsibilities:
Establish a clean and efficient development, test, and production environment.
Deliver secure, high quality smart contracts in Solidity.
Write and implement test suites covering the full range of code functionality.
Collaborate with the team to define architecture, quality standards, and best practices.
Diligently document all aspects of open-source contributions.
Create unique solutions to dApp-specific user experience challenges.
Build cutting-edge scalability solutions for the Ethereum network.
Requirements
The ideal candidate will have:
2+ years of experience developing in Solidity or in Web3 - you MUST be able to demonstrate this with public repositories or contracts. No other applications will be considered.
Working knowledge of scalability solutions, including zk-sync, optimistic rollups, or sharding.
A passion for cryptocurrencies and other peer-to-peer technologies

Few sectors are hot as blockchain right now - talk about professional growth\n\nNo one has done this before. We'll get things wrong - and that's okay! With your help, we'll get fewer things wrong, identify mistakes earlier, and improve processes to prevent future missteps.\n\nYou're in on the ground floor - you'll have a say in what we do and how we do it. By joining Swarm Technologies, you'll be joining a dynamic team on the bleeding edge of information (computer) security and blockchain - answering questions few have thought to ask.\n\n**If you're interested in**\n- technical challenges that cannot be solved via iteration\n- blockchain (Ethereum smart contracts in particular)\n- information security\n- malware reverse engineering automation\n- market design (a la Who Gets What and Why by Alvin Roth)\n- software development\n- unknown unknowns\n\n**then we're interested in you!**\n\n**The Ideal Candidate Is:**\n- independently motivated & self-directing\n- introspective: able to identify weak spots / problem areas our existing processes or code and suggest / implement solutions\n- takes an interest in information security topics - huge props for capture the flag (CTF) participation!\n- enjoys developing software\n\n**At Swarm Technologies, you'll tackle both big-picture and tactical problems, the following are a few examples.**\n\n**Example Big-Picture Problems**\n\nThe Ethereum block time leaves a lot to be desired for a marketplace that intends to supplant millions of malware scans a day.\n\nHow do we best reconcile millions of scans daily with a 15 second block time and today's block size limits?\n\nIn sum: PolySwarm must scale and must support scanning artifacts (files) that may contain confidential information. How do we best reconcile these needs with a default-public, Proof-of-Work Ethereum ecosystem?\n\n**Example Tactical Problem**\n\nPolySwarm is a twist on a prediction market - where security experts attempt to "predict" whether a file / URL or network traffic is malicious or benign. Alongside their prediction ("assertion"), experts "stake" a configurable amount of Nectar (NCT), PolySwarm's crypto token.\n\nSuppose Expert A is lazy and Expert B is a hardworking, upstanding security expert. It would be bad if Expert A was able to simply duplicate the assertions coming from Expert B, exploiting Expert B's hard work for profit. If assertions are placed directly on the public Ethereum blockchain, Expert A can do exactly that.\n\nHow can we design a system that keeps the assertion secret (so Expert B is out of luck) until some configured time, after which assertions are revealed and payouts distributed appropriately?\n\n**The Ideal Candidate possesses demonstrable experience in some or all of these technologies.**\n\nPolySwarm employs the following tools & languages:\nPython\nDocker (+ Swarm, Services, Stack)\nKubernetes (+ Helm)\nTerraform\nAnsible\nSolidity\nReact\nJavaScript\nRust\n\nRefer to our GitHub for examples of our usage: https://github.com/polyswarm\n\n**We Offer**\n- Competitive salaries\n- Excellent health, dental, vision coverage\n- Paid vacation days\n- Travel (if you like). We have offices in San Diego, Puerto Rico and Tokyo and we often find ourselves travelling elsewhere. If travel interests you, we can scratch that itch.\n- Flexible work hours - outside of scheduled meetings, we don't care when you work, we care about your output.\n- Powerful servers, laptops, desktops - whatever you need to be most productive! \n\nPlease mention the words **PLUG POTATO EASILY** when applying to show you read the job post completely (#RMjE2LjczLjIxNi4xNzA=).
