Senior Product Engineer

About ZetaChain

We're building something ambitious at ZetaChain: the first universal blockchain that connects everything—Bitcoin, Ethereum, every chain. We're backed by top investors, live on mainnet, and building the future of blockchain technology. If you're excited about working on big, meaningful problems with a world-class team, you're in the right place.

About the Role

ZetaChain is at the forefront of building the first fully interoperable layer-1 blockchain. We're looking for an experienced and passionate Product Engineer to spearhead the development of innovative Web3 applications powered by our cross-chain interoperability layer.

This role is perfect for someone who thrives on building new user-facing products from scratch, enjoys the fast pace of a startup, and wants to be on the bleeding edge of cross-chain Web3 technology. This role will 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

• 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
• Architect, plan, and execute projects, from initial concept to launch, by breaking down high-level goals into well-defined tasks and tickets for the team
• Conduct code reviews and provide constructive feedback to ensure code quality, maintainability, and adherence to best practices
• Act as the primary technical point of contact for the team, collaborating with product and design to clarify requirements and manage technical risks

You Should Have

• 6+ years of software engineering experience, with at least 1+ years in a tech lead or senior leadership role
• Strong full-stack background, with a focus on building consumer products
• Proven track record shipping production-grade applications, ideally in Web3 or fintech
• Experience with breaking down complex projects and guiding a team to successfully deliver them

Bonus Points

• Solid grasp of Web3 architecture: how contracts, wallets, assets, and RPC interactions work
• 3+ years of engineering team management
• 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. We know life happens, whether it’s travel, appointments, or family needs and we’re flexible when the schedule needs to shift. But generally, we value showing up, building together, and keeping the energy high. The company is a mix of remote and local team members.

Why Join Us?

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

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 Projects

Compensation

Base Salary: $140,000 – $190,000This 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.

In addition to the base salary, all full-time team members receive an additional 10% to 25% in liquid benefits with upside based on role, experience, and impact. We believe in building together and sharing in the long-term success of the network. Compensation packages are designed to be competitive and aligned with the growth of both the team and the ecosystem.

Let’s build the first Universal Blockchain together.
