Our software allows groups of operators—large and small—to collaboratively run a single validator while minimizing single‑point‑of‑failure risk and maximizing client diversity. We are a venture‑backed, remote‑first team that values open‑source ethos, long‑term thinking, and empirical decision‑making.

We’re looking for a product‑minded Full‑Stack Engineer who can take UI/UX ideas, wire them to backend services, and ship features that help operators run distributed validators with confidence.

You’ll work closely with protocol & infra engineers, pulling consensus‑layer telemetry that our analytics team already prepares, and surfacing it through APIs and dashboards that delight end users.

Responsibilities

• Build end‑to‑end features with Next.js (React/TypeScript) on the front‑end and NestJS(Typescript) on the back‑end.
• Query ClickHouse and MongoDB to consume outputs from existing analytics pipelines; transform & expose that data via REST endpoints and typed client SDKs.
• Integrate consensus‑layer insights (beacon duties, attestation stats, slashing alerts) so stakers understand their validator health.
• Interact with deployed Solidity smart contracts using viem/ethers.js/web3.js to read on‑chain state or submit transactions (e.g., validator registration, withdrawal credentials updates).
• Automate testing & deployment with GitHub Actions and serverless hosting on Vercel.
• Contribute to technical road‑mapping, architecture reviews, and RFCs in our open, async‑first culture.

Requirements

• 4+ years building production full‑stack web applications.
• Advanced TypeScript skills across React and Node.js.
• Demonstrated experience designing & consuming REST APIs.
• Ability to query and optimise ClickHouse or another analytic DB, plus familiarity with MongoDB.
• Working knowledge of the Ethereum consensus layer (Beacon Chain duties, attestations, slashing conditions).
• Proven experience interacting with deployed Solidity contracts (reading state, sending signed transactions, gas estimation, event parsing).
• CI/CD mindset; you automate workflows with GitHub Actions (or similar) and treat infrastructure as code.
• Strong testing discipline: unit, integration, and E2E where it matters.
• Excellent written communication; comfortable in an async, globally distributed team.

Nice to have

• Experience with SQL
• Exposure to GraphQL (Apollo Server/Federation) — some internal services use it.
• Contributions to Ethereum client code, staking protocols, or DV research (Lido, DVT).Experience with p2p networking stacks (libp2p, gRPC) or BFT systems.
• Familiarity with container orchestration (Kubernetes) and infrastructure‑as‑code (Terraform).
• Go proficiency (many beacon‑chain tools use them).
• Data‑visualisation skills (D3.js, Recharts) for rich dashboards.
