ABOUT THE ROLE
We are looking for a Senior Protocol Engineer to join our Rollup team. This is a hands-on, full-time engineering role focused on building and scaling our Bitcoin-secured Layer 2 rollup on Rootstock. This is a protocol role: you’ll work directly on the chain on topics such as sequencing, block derivation, consensus and finality, bridge and proof system. You will join a small team of senior engineers with high ownership. You will design, build, test and operate core components, and you will take part in the technical decisions of the project.
KEY RESPONSIBILITIES
- Design, build and maintain core protocol components: execution and consensus clients, sequencer, block derivation and batch submission to the parent chain.
- Work on the bridge and the proof system: deposits, withdrawals, cross-layer messages and state validation.
- Maintain a large open source codebase: learn how its parts work together, make changes that are safe for a live network, and keep the code easy to evolve.
- Review code, write design docs and RFCs, and take part in architecture decisions.
- Test and debug a distributed system: unit to adversarial tests, local devnets, reorgs, node desync and performance problems.
- Deliver and operate releases on public chains: upgrades, hard forks, monitoring and incidents, etc.
- Collaborate with Product, DevOps and Security to plan and ship each release.
WHAT YOU BRING
Must have
- 5+ years of professional software engineering, with at least 2 years in blockchain core or protocol development (node clients, consensus, etc.).
- Solid production experience in mainstream languages (for example Go, Rust or Java).
- Deep knowledge of blockchain internals and the EVM: consensus, P2P networking, state and storage, transaction lifecycle, JSON-RPC, etc.
- Experience working effectively in large codebases you did not write.
- AI-assisted development is a core part of your work, while owning what you deliver.
- Autonomy and ownership: you help define the work, not only execute assigned tasks.
- Good English, spoken and written, since the team is international and remote.
Nice to have
- Professional experience with Go and/or Rust.
- Hands-on experience with Ethereum Layer 2 rollups (optimistic or ZK).
- Understanding of rollup design: sequencing, data availability, derivation, finality, etc.
- Contributions to open source blockchain clients or rollup stacks.
- Experience with fault proof systems or validity proofs.
- Knowledge of Bitcoin and EVM compatible chains.
- Experience with Docker, cloud providers, Prometheus and Grafana.
- Able to read and review Solidity (bridge and system contracts).
ROOTIES BENEFITS
At RootstockLabs, we don’t just offer a job, we offer a community. Here’s what you can expect when you join us:
