# Who we are\nNamebase is on a mission to enable freedom, security, and ownership on the Internet. We’re doing this by making Handshake — a new decentralized DNS protocol — easy-to-use. You can think of our product as a GoDaddy for Handshake. \n\n# Context\nHandshake is a new naming blockchain (we didn’t create it) that functions as a peer-to-peer root DNS that can replace Certificate Authorities. It's a Proof-of-Work protocol like Bitcoin, except instead of using the coins as money, you use Handshake coins to register domain extensions (ie .com, .net, .org) on the Handshake blockchain. Unlike traditional domain names that can only be rented, you truly own your Handshake extensions forever — no one can take the extensions from you or prevent others from accessing them. And rather than being limited to a small number of extensions like .com and .org (blacklisted on Handshake for compatibility with traditional DNS), you can register almost any name you can think of. These attributes are becoming increasingly important in a world that’s trending towards more censorship and less freedom for individuals.\n\n# The role\nSince launch six months ago we’ve already processed over $20M in transaction volume and tens of thousands of Handshake name registrations. We work in a highly collaborative environment across a distributed team (currently in US and Australia). Open communication is the standard — strategy discussions occur in slack, not behind closed doors. New initiatives have a single owner to maintain focus while feedback is solicited from everyone.\n\nWe’re looking for a backend engineer to work on our infrastructure — primarily crypto wallets — and less so our user-facing APIs. You'll work closely with our existing engineering team on complex system design problems. Node.js experience is required, Golang experience is preferred. \n\nPlease mention the words **PARK PROPERTY BATTLE** when applying to show you read the job post completely (#RMjE2LjczLjIxNi4yMzQ=).

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 (#RMjE2LjczLjIxNi4yMzQ=).
