Protocol Engineer - Platform
You will own the infrastructure that runs institutional grade blockchain operations with depth in Ethereum validator infrastructure consensus and execution client operations and the platform layer that makes all of it reliable observable and scalable You will work closely with clients understanding their constraints translating requirements into platform capabilities and collaborating on integrations You will operate production systems where the failure mode is institutional money and reputation You will contribute to architecture decisions across modules such as staking MPC quorum coordination policy engine and vaults
Responsibilities
- Own and operate Ethereum validator infrastructure at scale — consensus clients (Lighthouse Prysm Teku Nimbus), execution clients (Geth Nethermind Besu Reth), and the tooling that keeps them healthy diverse and performant.
- Build and maintain the platform layer underneath validator operations: cluster lifecycle management, client upgrades, peer connectivity, fork tracking, and the observability stack that surfaces what matters.
- Manage slashing protection, key management, and signer infrastructure (Web3Signer, distributed validators, HSM/MPC-backed signing) at the level of rigor institutional staking demands.
- Harden shared platform infrastructure: EKS environments, GitOps pipelines, secrets management, networking, CI/CD, and the data plane.
- Partner closely with clients on integration work across staking tokenization DeFi and validator engagements Translate their constraints into platform requirements and ship the code that closes the gap.
- Generalize patterns from client work into reusable platform capabilities so the next engagement doesn't start from zero.
- Operate production systems where the failure mode is institutional money and reputation On-call incident response post mortems.
- Contribute to architecture decisions across modules staking MPC quorum coordination policy engine vaults.
