As a team lead, you'll play a pivotal role in shaping our product engineering culture, mentoring other developers, and pushing the boundaries of what’s possible with cross-chain dApps. Blockchain experience isn't required if you have a proven track record of building successful products. This role won’t need to write smart contracts but you will need to develop a strong understanding of Solidity and how to interact with Web3 smart contracts and assets. Experience across other chains like Solana, SUI, Bitcoin, or TON is a huge plus. What You'll Do Lead a small, agile team of product-focused engineers building powerful cross-chain Web3 applications Build full-stack features that touch everything from contract interactions to slick frontend interfaces Work closely with design, protocol, and ecosystem teams to bring innovative universal apps to life Solve hard technical problems, from user onboarding to high-throughput systems Contribute to open-source projects and shape best practices in a rapidly evolving space You Should Have 3+ years of software engineering experience Strong full-stack background, with a focus on building consumer products Proven track record shipping production-grade applications, ideally in Web3 or fintech Bonus Points Solid grasp of Web3 architecture: how contracts, wallets, assets, and RPC interactions work Experience across multiple blockchain ecosystems (e.g., Solana, SUI, Bitcoin, TON) Background at both fast-moving startups and more structured organizations History of launching products from 0 → 1 Experience building applications at scale (millions of users) In-Office Culture We believe that collaboration is supercharged when we share space together. Many members of our team work hybrid from our San Francisco office, and we aim for 2 to 3 in-office days per week.

At ZetaChain, you'll get to: Build truly novel Web3 products that don't exist anywhere else Work alongside a world-class protocol team that's building foundational cross-chain infrastructure Lead our growing product engineering team and define the future of Web3 UX Our Tech Stack We’re a polyglot team and value engineers who can navigate across boundaries. You are not expected to be an expert in every area and you’ll be working closely with our Protocol Engineering and SRE teams but it helps to understand the tools we use. Our core stack includes: Frontend: TypeScript, Next.js, Redux Toolkit, GraphQL, tRPC, Ethers.js Smart Contracts: Solidity, Foundry/Hardhat, Rust Backend / Infra: Go, Rust, Docker, Kubernetes Others: GitHub Actions Compensation Base Salary: $140,000 – $180,000 (San Francisco benchmark)This range reflects base salaries for roles in the San Francisco market. For candidates in other locations, compensation is adjusted to remain competitive within their local market.
