You’ll be part of an engineering-first team solving deep, complex problems that haven’t been tackled before. If you thrive in an environment about optimisation, distributed systems, and real-time performance at scale, this is your kind of challenge.

This is a remote team who work within AEST, strong preference for AU/NZ location, but all applications must be from timezones within GMT +7 and GMT+13.

About the Role

We’re hiring a Senior Backend Engineer to help design and optimise the core infrastructure across both an on/off chain EVM/Typescript architecture. You’ll be working on high-throughput systems that redefine execution speed and efficiency in DeFi.

What You’ll Be Doing

• Designing and implementing scalable, distributed backend systems to handle millions of orders per second.
• Optimising for latency and performance
• Working with event-driven architectures, real-time data pipelines, and high-throughput APIs.
• Collaborating with front end and protocol engineers to build an entirely new class of DeFi trading infrastructure.
• Ensuring fault tolerance, efficiency, and security across the platform.

What We’re Looking For

Essential Skills:

• Strong experience in backend development using Node.js & TypeScript building applications that have proven to scale
• Deep understanding of and experience with distributed systems - scalability, high availability, and performance tuning.
• Strong experience with CI/CD, AWS.
• Experience building or contributing to production DeFi or web3 projects.

Highly desirable:

• Prior work with real-time trading systems or large-scale on-chain applications
• Solidity/smart contract knowledge is not essential but a bonus.

Why Join Us?

• Fully remote (AEST ± 3 hours)
• Get paid on-chain (USD stables)
• Work alongside world-class engineers building core DeFi infrastructure
• Get early ownership in a protocol with $700M+ TVL and serious momentum
• Solve complex, technical problems with real user impact
• No politics - just sharp, curious engineers delivering fast

DV Labs is building the next generation of distributed validators to make Ethereum staking more resilient, decentralized, and secure.

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.

About the team - How we work?

• Async‑first: proposals & design docs precede meetings.
• Small, senior team: high trust & ownership.
