We are programming a market that will produce crowdsourced threat intelligence (malware detection today, more tomorrow).{linebreak}{linebreak}** Blockchain experience not required! **{linebreak}{linebreak}We'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{linebreak}{linebreak}No 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.{linebreak}{linebreak}You'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.{linebreak}{linebreak}**If you're interested in**{linebreak}- technical challenges that cannot be solved via iteration{linebreak}- blockchain (Ethereum smart contracts in particular){linebreak}- information security{linebreak}- malware reverse engineering automation{linebreak}- market design (a la Who Gets What and Why by Alvin Roth){linebreak}- software development{linebreak}- unknown unknowns{linebreak}{linebreak}**then we're interested in you!**{linebreak}{linebreak}**The Ideal Candidate Is:**{linebreak}- independently motivated & self-directing{linebreak}- introspective: able to identify weak spots / problem areas our existing processes or code and suggest / implement solutions{linebreak}- takes an interest in information security topics - huge props for capture the flag (CTF) participation!{linebreak}- enjoys developing software{linebreak}{linebreak}**At Swarm Technologies, you'll tackle both big-picture and tactical problems, the following are a few examples.**{linebreak}{linebreak}**Example Big-Picture Problems**{linebreak}{linebreak}The Ethereum block time leaves a lot to be desired for a marketplace that intends to supplant millions of malware scans a day.{linebreak}{linebreak}How do we best reconcile millions of scans daily with a 15 second block time and today's block size limits?{linebreak}{linebreak}In 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?{linebreak}{linebreak}**Example Tactical Problem**{linebreak}{linebreak}PolySwarm 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.{linebreak}{linebreak}Suppose 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.{linebreak}{linebreak}How 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?{linebreak}{linebreak}**The Ideal Candidate possesses demonstrable experience in some or all of these technologies.**{linebreak}{linebreak}PolySwarm employs the following tools & languages:{linebreak}Python{linebreak}Docker (+ Swarm, Services, Stack){linebreak}Kubernetes (+ Helm){linebreak}Terraform{linebreak}Ansible{linebreak}Solidity{linebreak}React{linebreak}JavaScript{linebreak}Rust{linebreak}{linebreak}Refer to our GitHub for examples of our usage: https://github.com/polyswarm{linebreak}{linebreak}**We Offer**{linebreak}- Competitive salaries{linebreak}- Excellent health, dental, vision coverage{linebreak}- Paid vacation days{linebreak}- 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.{linebreak}- Flexible work hours - outside of scheduled meetings, we don't care when you work, we care about your output.{linebreak}- Powerful servers, laptops, desktops - whatever you need to be most productive!

If youโ€™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.{linebreak}{linebreak}Blockstack 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 monthโ€™s payout and there is no limit to how many months you are eligible, we hope you'll partake in these monthly payouts indefinitely. {linebreak}{linebreak}Developers 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. Decemberโ€™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.{linebreak}{linebreak}Submitting existing apps to the program is allowed provided integration with Blockstack is added and fully functional before ranking begins.{linebreak}{linebreak}[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). {linebreak}{linebreak}*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.* {linebreak}{linebreak}# Requirements{linebreak}Familiarity with a frontend language such as Javascript or React is all that's needed to build on Blockstack.
