Job description

Who Are We?

The Obol Collective is quickly becoming the foundation of layer 1 blockchains like Ethereum through Obol Distributed Validators (DVs) — our industry leading validator technology that improves performance, lowers risks and increases rewards. We’re already securing $1B+ of ETH through key partners like Lido & EtherFi and we’re expecting continued rapid growth.We’re backed by top tier angels like David Hoffman, Anthony Sassano, Sreeram Kannan, Dankrad Feist and tier 1 investors like Pantera, Archetype, Ethereal Ventures, Placeholder and more.

DV Labs is both the first and largest contributor to the Obol Collective, including building much of the core technology behind the project.

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.

About the team - How we work?

• Async‑first: proposals & design docs precede meetings.
• Small, senior team: high trust & ownership.
• Open‑source by default: most code and discussions are public.

Our Values

• Synergistic
• Secure
• Innovative
• Reliable

Compensation

• Competitive salary in dollars
• Full remote company - Work from wherever you want
• Possibility to attend to relevant Conferences
• 2 Recharge weeks at the end of the year
