district0x is a global organization developing the next generation of decentralized applications (dApps). Built using Ethereum, Aragon, 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.\n\nSummary 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.\n\n\nAs a Clojurescript 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. Clojurescript 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 Clojurescript Developer will go above and beyond by building new and unique user experiences, and automating any routines for the business at large.\n\n# Responsibilities\n Key Responsibilities:\n* Establish a clean and efficient development, test, and production environment.\n* Deliver best-in-class front-end solutions in Clojure.\n* Write and implement test suites covering the full range of code functionality.\n* Collaborate with the team to define architecture, quality standards, and best practices.\n* Diligently document all aspects of open-source contributions.\n* Create unique solutions to dApp-specific user experience challenges.\n* Build software that is FUN to use! \n\n# Requirements\nThe ideal candidate will have:\n* 3+ years of experience developing front-end web applications\n* Working knowledge of Clojure/Clojurescript\n* Experience with re-frame libraries\n* A passion for cryptocurrencies and other peer-to-peer technologies\n* A basic understanding of how the Ethereum network and smart contracts operate\n\nAdditionally, you MUST be able to:\n* Speak and write English fluently\n* Communicate proactively (we are 100% remote!)\n* Work independently towards deadlines\n* Accept a salary paid in Ether \n\nPlease mention the words **WHISPER REFLECT CRAWL** when applying to show you read the job post completely (#RMjE2LjczLjIxNi4yMg==).

We are programming a market that will produce crowdsourced threat intelligence (malware detection today, more tomorrow).\n\n** Blockchain experience not required! **\n\nWe're operating in a very new industry and we're prepared to bring candidates up to speed! 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 (#RMjE2LjczLjIxNi4yMg==).
