  • ESTIMATED DURATION: 40h/week – Long-term


Who You Are

You are a brilliant and ambitious builder who takes great pride in your work and invests actively in your team. You will be joining a seed-stage startup, so you must be able to roll-up your sleeves and get the work done while dreaming up long-term roadmaps. You also have:

  • Deep expertise in blockchain fundamentals and security best practices. Our client will look for a track record that demonstrates your ability to architect, develop, and operationalize robust blockchain protocols and dApp services – as well as a general passion for the crypto space
  • Aptitude for both autonomous work and building strong engineering culture at early-stage startups
  • Understanding of tokenomics and governance design
  • Proven success in the architecture of scalable traditional cloud solutions, with solid understanding of Javascript language and runtime that you leveraged to deliver live production end-to-end solutions
  • 3+ years’ experience recruiting and managing an engineering team. Experience doing this at an early-stage startup and/or rapid growth environment is highly desirable
  • Other nice to haves:
  • Bachelor’s degree or equivalent experience in Computer Science or another field involving programming (e.g., mathematics, physics)
  • Experience building/deploying production Rust-based smart contracts

What You Will Do

  • Design, build, and optimize their blockchain, making critical recommendations and decisions on their protocol architecture, incentive structures, and infrastructure features
  • Own the development of their blockchain features, nodes, and API & application ecosystem, which includes identifying and implementing the most appropriate programming languages and frameworks
  • Develop the architectural framework to integrate across multiple blockchain technologies (such as wallets/Dapps, Layer 2 scaling solutions, decentralized storage) and traditional (web2) apps and operating systems
  • Recruit and build a stellar web3 engineering team and shape the engineering culture of the company
  • Contribute to their long-term technical and product strategy to fulfill their mission to rebuild public safety

Our client is tackling some extremely complex problems, which will put to good use your formidable skills and imagination in creating solutions that others have not seen before.
