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.
  • 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.
  • Substantial experience building and operating distributed systems in production, ideally where reliability and security are first-class concerns.
  • Build Dream Teams.
  • High agency. We operate decentralized command - squad leads own within their mandate. You should be the kind of engineer who finds the work, not the kind who waits for it.

Requirements

  • Experience operating systems that hold or move value - custody, payments, exchanges, key management, HSMs, MPC - or a clear track record in adjacent high-stakes domains.
  • Comfort being customer-facing.
  • For staff candidates: a track record of setting technical direction across multiple teams or engagements, and of growing the engineers around you.
  • Experience with distributed validator technology (DVT) - Obol, SSV, or similar.
  • Experience with MPC, threshold signing, or secure enclaves (Nitro, SGX) in production.
  • Familiarity with tokenization or DeFi protocol integration at the infrastructure level.

Nice to have

  • Experience with MEV infrastructure - mev-boost, relay operation,builder/proposer separation, and its implications for validator profitability and performance.

Compensation

  • $200,000 - $250,000 USD

  • Competitive base salary and discretionary bonus
  • Flexible Time Off (paid)
  • Company-paid health and protective benefits for employees, partners, and other dependents
