Additionally, our marketing websites are multi-lingual and updated about once per week, so this would be about 5% of your time. \n\n\n**Join PolySwarm.**\n\nWe're developing innovative solutions to age-old information security problems - and we need your help.\n\nPolySwarm is a marketplace that produces crowdsourced threat intelligence (malware detection today, more tomorrow). \n\nNo one has done this before. We'll get things wrong - 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 PolySwarm, 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\nIf you are:\n\n* proficient with Python, Docker, JavaScript, HTML, CSS/SASS, React, Redux, NodeJS, TypeScript, and Templating (Mustache/Handlebars)\n* familiar with Jekyll/Gatsby\n* experienced at creating clean/efficient UX\n* experienced building both the front-end and back-end for a web application\n* experienced at developing/managing a multi-language web application\n\n... then we are interested in you.\n\n**The Ideal Candidate Is...**\n\n* independently motivated & self-directing\n* introspective: able to identify weak spots / problem areas in our existing processes or code and suggest / implement solutions\n* interested in creating a top quality user experience for both desktop and mobile users\n* interested in web application development\n* has an eye for design\n\n\n**We Offer**\n\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 - we have core hours on weekdays, but outside of scheduled meetings, we don't care *when* you work, we care about your output.\n* Remote Ok - You can work remotely, or you can work from one of our offices\n* Powerful servers, laptops, desktops - whatever you need to be most productive!\n\n In compliance with federal law, all persons hired will be required to verify identity and eligibility to work in the United States and to complete the required employment eligibility verification form upon hire.\n\n**About PolySwarm**\n\nThe PolySwarm Team is made up of InfoSec veterans with decades of experience in government and industry.

***In compliance with federal law, all persons hired will be required to verify identity and eligibility to work in the United States and to complete the required employment eligibility verification form upon hire.***\n\n\n**Job type:** Full-time \n**Role:** Full-Stack Developer \n**Experience level:** Mid-Level, Senior\n**Industry:** Cryptocurrency, Cybersecurity, Network Security, Blockchain \n**Company size:** 11-50 people\n**Location:** San Diego, CA, San Juan, Puerto Rico, Tokyo, Japan or **Remote**\n\n\n**Join the Swarm**\n\nAt Swarm Technologies, Inc, we're developing innovative solutions to age-old information security problems - and we need your help.\n\nAt its core, PolySwarm is market design enabled by Ethereum smart contracts. 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!

If you’ve been looking for the right opportunity to get into crypto, experiment with decentralized applications, or just want a side hustle that takes you to the cutting edge, App Mining with Blockstack is the perfect opportunity.\n\nBlockstack is looking for developers to participate in App Mining, a program that pays developers to build decentralized applications on Blockstack. This is a fully remote and independent position, you have complete creative control over your application and development schedule. There is a monthly deadline to submit your application to be eligible for that month’s payout and there is no limit to how many months you are eligible, we hope you'll partake in these monthly payouts indefinitely. \n\nDevelopers are paid out of a growing pool of Bitcoin according to their rank as determined by independent App Reviewers including Product Hunt and Democracy Earth. December’s App Mining run will award the top ranked app **$20,000 USD** (paid in Bitcoin) and all other submissions receive payment equivalent to 80% of the total paid to the app in front of them in the ranking. [$20,000, $16,000, $12,800, etc.] The total payment pool will grow on a regular basis, in the first round of payments there were 17 eligible apps. It's still very early in the world of dapps - earning near the top of the list is more than possible with a very early stage application.\n\nSubmitting existing apps to the program is allowed provided integration with Blockstack is added and fully functional before ranking begins.\n\n[Meet those that participated in our alpha run](https://app.co/mining/september-2018?utm_source=angellist&utm_medium=jobs&utm_campaign=angellist_november) and [sign up for the program](https://app.co/mining?utm_source=angellist&utm_medium=jobs&utm_campaign=angellist_november). \n\n*Blockstack is a new internet for decentralized apps. Our open-source community of 15920 members globally is building protocols & tools that make it easy to build scalable decentralized apps.* \n\n# Requirements\nFamiliarity with a frontend language such as Javascript or React is all that's needed to build on Blockstack.
