It is a multidisciplinary exercise in distributed systems, decentralised finance, blockchain consensus mechanisms, cyber security, applied cryptography, and user facing applications. Our engineering team of 15 is on the lookout for additional people to tackle this challenge with us. We’re mostly office-based in Berlin, Germany, but offer flexible working arrangements and remote work for some part of the year.</p><h2 id="what-s-the-job">What’s the Job?</h2><p>This role is open to a European based Senior Full Stack Engineer who wants to work in Web3. Experience in Typescript is ideal, but the role is open to everybody with Full Stack engineering knowledge and an interest in the Web3/Blockchain space.</p><p>If you join us, you will likely focus your efforts on several of these three projects depending on your skills and interests:</p><ul><li><strong>State Chain Tooling:</strong> we are developing our own standalone blockchain using the <a class="font-medium hover:text-gray-900 transition-colors" href="https://substrate.io" target="_blank" rel="noopener">substrate blockchain development framework</a>.

Our team has a diverse range of backgrounds and experiences to share, and hopefully you’ll be able to share yours with us too.</p><p>The Web team itself is composed of four brilliant young engineers with plenty of experience working with our technologies already.</p><p>We offer all Berlin based employees standard employment contracts under German law. Those that work with us remotely outside of Germany are typically contractors. On top of that, there are benefits for public transport, gym memberships and personal development like language courses.</p><h2 id="who-should-apply">Who Should Apply?</h2><p>This is the role for you if you:</p><ul><li>Are based in Europe and are willing to relocate to Berlin</li><li>Have 4+ years of professional full stack development experience</li><li>Are interested in decentralisation and blockchain technology</li><li>Have knowledge or experience with building and scaling systems</li><li>Looking to push the boundaries of your knowledge in Web3</li><li>Salaries and Token packages on offer are commensurate with skill and experience. Please indicate your expected salary range when applying, and we will take that into consideration during the interview process.</li></ul><h2 id="the-process">The Process</h2><p>Please submit your CV for review. A screening call will be conducted by our COO. The next step is a take home challenge which will then be expanded upon in a 1-hour in-person or remote code interview.
