Tech Lead is to guide and support a cross-functional software engineering team responsible for delivering high-impact, scalable, and maintainable solutions. You will lead technical design, promote engineering best practices, and foster collaboration across product, design, and operations. The ideal candidate combines strong hands-on technical skills with leadership and mentoring capabilities. This role is ideal for a senior-level engineer who thrives in a coding environment and wants to scale their impact by shaping the blockchain architecture of DeFi protocols, mentoring developers, and driving technical excellence across the stack.

Key Responsibilities: Technical Leadership


  • Drive the technical direction of projects, ensuring alignment with architectural principles and long-term platform goals
  • Own and evolve the micro-architecture, ensuring protocols are composable, modular, scalable, and maintainable
  • Review code and promote clean, efficient, and well-tested software
  • Act as the technical point of contact for your team, enabling clear communication across disciplines
  • Guide the team in applying best architectural and security practices, and gas optimizations
  • Shape long‑term protocol roadmap, balancing new DeFi features with platform stability and security



Hands-on Engineering


  • Actively contribute high-quality code (:30–50% of your time), focusing on critical components, prototypes, and performance-sensitive areas
  • Set and enforce coding standards, code structure, and review practices across the team
  • Troubleshoot and optimize complex systems, ensuring observability, fault tolerance, and performance tuning are integral to the design



Team Collaboration & Mentorship


  • Lead technical planning and estimation, ensuring realistic timelines and scalable designs
  • Balance delivering new features with refactoring and reducing technical debt
  • Champion best practices in CI/CD, infrastructure-as-code, and automated testing to ensure rapid, reliable deployments
  • Hire, onboard and coach junior/mid engineers



What You’ll Need: Requirements


  • 6+ years of professional experience in software development; 2+ years in a senior or tech leadership role
  • Expert in Solidity/Yul with production main‑net deployments, working knowledge of Rust (Anchor) and TypeScript/Node.js tooling
  • Deep understanding of EVM internals and typical L2 designs (Optimistic, ZK Rollups)
  • Hands‑on experience with Hardhat/Foundry, fuzz & invariant testing, and CI/CD pipelines (Docker, GitHub Actions)
  • Proven track record of smart‑contract security (audits, threat modelling, remediation of critical issues)
  • Excellent problem-solving, communication, and leadership skills



Nice to haves


  • Background in regulated or complex industries (e.g., finance, healthcare)
