Technical Lead (Blockchain)

1inch is the DeFi ecosystem building financial freedom for everyone. 1inch products help users and builders trade, hold and track digital assets - with the self-custody, comprehensive security and the intuitive user experience they need to unlock the potential of true crypto ownership. 1inch protocols and APIs provide core infrastructure across the DeFi industry and beyond.

So if you’re someone who thinks big, moves fast and wants to make an impact right from day one, then get ready to join our industry-changing team.

Location: We hire with a focus on Dubai and Europe. For this role, we prefer candidates who are either based in Dubai or working remotely within +/- 4 hours GST time.

We're looking for a Tech Lead to guide a cross-functional software engineering team. This role is perfect for a senior-level engineer who wants to scale their impact by shaping the blockchain architecture of DeFi protocols and mentoring developers.

As the technical leader, you'll be responsible for guiding your team in delivering high-impact, scalable, and maintainable solutions. This requires a unique blend of hands-on technical skills, leadership, and mentoring abilities. You will drive technical design, promote engineering best practices, and foster strong collaboration across product, design, and operations.

Responsibilities

• 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
• Guide the team in applying best architectural and security practices, and gas optimisations
• Shape long‑term protocol roadmap, balancing new DeFi features with platform stability and security
• 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 optimise complex systems, ensuring observability, fault tolerance, and performance tuning are integral to the design
• 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
