Responsibilities

Building various components that interact with EVM-based smart contracts, such as:

  • Developer SDKs that are used in frontend and backend applications.
  • Offchain services that interact with smart accounts.
  • Frontend applications that are used directly by end users.
  • Developer-facing applications, such as developer hubs and dashboards.
  • Work closely with the team to ship new products and develop solutions for challenging technical problems.
  • Deliver high-quality code from concept until production.
  • Dive into the code of other team members to provide thorough reviews and contributions outside of your own responsibilities.


Relevant experience

  • 3+ years of relevant experience with blockchain technology (EVM-focused).
  • 3+ years of experience writing TypeScript/JavaScript code for production environments, preferably both frontend and backend
  • Experience building developer tooling, crypto wallets (preferably smart accounts), bridging technologies, blockchain nodes, relayer or intent-based systems.
  • Experience reading Solidity contracts and translating them into code in other languages.
  • Ability to balance shipping quickly with building a stable infrastructure.
  • Self-starter, problem solve from the root cause, able to break down complex problems into simpler components and chart the phases of getting to a stable and scalable solution.
  • A hustler mentality; founding a company, working in startups (pre-series A), or building side projects (open source is a plus).
  • Able to be a thought leader and highly collaborative to drive toward 10x outcomes.


Our tech stack
