Senior Protocol Engineer

This is a fully remote position, open to applicants in Europe.

📋 Description

• Design, develop, and sustain essential protocol components: execution and consensus clients, sequencer, block derivation, and batch submission to the parent chain.

• Work on the bridge and proof system: handling deposits, withdrawals, cross-layer messaging, and state validation.

• Oversee a substantial open-source codebase, implementing changes that ensure the safety of a live network.

• Review code, produce design documents and RFCs, and engage in architectural decision-making.

• Test and troubleshoot a distributed system, including adversarial tests, local development networks, reorganizations, node desynchronization, and performance issues.

• Deliver and manage releases on public blockchains, covering upgrades, hard forks, monitoring, and incident management.

• Collaborate with Product, DevOps, and Security teams to plan and execute each release.

⛳️ Requirements

• At least 5 years of professional software engineering experience, including a minimum of 2 years in blockchain core or protocol development (e.g., node clients, consensus).

• Strong production experience in mainstream programming languages (such as Go, Rust, or Java).

• Extensive understanding of blockchain internals and the EVM: including consensus, P2P networking, state and storage, transaction lifecycle, JSON-RPC, etc.

• Proven ability to work effectively within large codebases that you did not create.

• AI-assisted development is an integral part of your role, while you take full ownership of your deliverables.

• Demonstrated autonomy and ownership: you contribute to defining the work, rather than just executing assigned tasks.

• Proficient in English, both spoken and written, as the team operates internationally and remotely.

🏝️ Benefits

• Competitive compensation package along with unique benefits aimed at fostering your growth and well-being.

• Fully remote work opportunities available from Europe and Latin America, with access to global coworking spaces.

• Paid vacation and sick leave days.
