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==).
