Senior Software Engineer, Protocol (Rust)

OP Labs builds Optimism, an open-source blockchain network that powers the next generation of financial infrastructure. Hundreds of companies, from the world's largest enterprises like Sony, Coinbase, Kraken, Uniswap, OKX, and Bitpanda to the most ambitious early-stage builders, use the OP stack to launch their own blockchains and bring their users onchain. Today, over 65% of Layer 2 activity on Ethereum runs through the OP stack.

Our Protocol Team designs and operates the core specifications and clients defining the stack. This creates opportunities to improve the underlying protocol while developing differentiated capabilities for enterprise chain operators. Near term projects may cover:

We are seeking mission-driven contributors who thrive on tackling complex computer science challenges while delivering high quality code with high-velocity.

• Developing kona-node and related Rust-based consensus-client infrastructure as a fully compatible and production-ready alternative to op-node

• Implementing native account abstraction across the stack.

• Developing premium protocol capabilities that support OP Enterprise

• Own features through the full lifecycle: from architecture, implementation, and docs to deployment and monitoring. Working cross functionally to create maximum impact.

• Build rigorous conformance and adversarial tests to ensure implementation compatibility.

• Execute safe protocol upgrades and resolve complex availability/performance issues.

• Use AI-assisted engineering tools effectively while maintaining rigorous standards for correctness, security, review, and technical ownership.
