Full-Stack Engineer

Summary

Join DV Labs, a venture-backed, remote-first team, as a Product-Minded Full-Stack Engineer. You will build end-to-end features using Next.js and NestJS, query data from ClickHouse and MongoDB, integrate consensus-layer insights, and interact with Solidity smart contracts. Your responsibilities include automating testing and deployment, contributing to technical roadmapping, and working in an async-first culture. This role requires 4+ years of full-stack web application development experience, advanced TypeScript skills, and experience with REST APIs and Ethereum's consensus layer. You should also possess a strong testing discipline and excellent written communication skills. The ideal candidate will have experience with SQL, GraphQL, and contributions to Ethereum client code or staking protocols.

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

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

Preferred Qualifications

• 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

Benefits

• 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
• Equipment budget
