Create flexible and precise queries that fit your needs exactly. Example:
React.js, -USA
×
Laravel, Vue.js, -Contract
×
will get you jobs that are
(React.js and not in USA) or
(Laravel and Vue.js and not Contract/Freelance).
You can mix and match any tags, negations and groups in any order. And don't worry about typos – the search is fuzzy.
DV Labs
Remote
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.
- 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
- Equipment budget
Thanks for submitting your application! We’re excited to connect and hopefully build amazing things together.
Best of luck!

About Status
Status is building the tools and infrastructure for the advancement of a secure, private, and open web3.
With the high level goals of preserving the right to privacy, mitigating the risk of censorship, and promoting economic trade in a transparent, open manner, Status is building a community where anyone is welcome to join and contribute.
As an organization, Status seeks to push the web3 ecosystem forward through research, creation of developer tools, and support of the open source community.
As a product, Status is an open source, Ethereum-based app that gives users the power to chat, transact, and access a revolutionary world of Apps on the decentralized web. But Status is also building foundational infrastructure for the whole Ethereum ecosystem, including the Nimbus ETH 1.0 and 2.0 clients, the Keycard hardware wallet, and the Waku messaging protocol, the p2p communication layer for Web3.
As a team, Status has been completely distributed since inception. Our team is currently 200+ core contributors strong, and welcomes a growing number of community members from all walks of life, scattered all around the globe.
We care deeply about open source, and our organizational structure has minimal hierarchy and no fixed work hours. We believe in working with a high degree of autonomy while supporting the organization’s priorities.
We are looking for an experienced JavaScript developer to join our Web team, who will take ownership of certain web-related areas at Status, including a web browser crypto wallet. Your role will include working on our crypto wallet and other other Status web assets while collaborating with colleagues across the stack (QA, other developers, ui/ux, product, etc.) to deliver great features to our users.
Our stack is built on modern foundations – a monorepo powered by TypeScript, React, Storybook, Vite, Vitest, Playwright, ESLint, Prettier, pnpm, and Turborepo. As we work in the open and are fully open-source, you can get a better idea of who we are and the work we are doing by browsing our Status Web repository.

We don’t expect you to have a background in everything we use, but we do expect strong JavaScript fundamentals and experience working with React, TypeScript, and crypto web browser wallets.
We function as generalists, often undertaking a variety of challenges, and deeply care about the quality of our work. We look forward to collaborating with experienced individuals who can operate independently, make important decisions, and take ownership. The ideal candidate is comfortable working in European (or nearby) time zones, along with the majority of the existing team, but we welcome applications from other regions as well.
Key responsibilities:
- Building secure, robust, and well-cached APIs
- Cost-effective calling of RPC and node provider APIs
- Working with various browser storage solutions
- Integrating libraries to create, sign, and decode transactions
- Building and maintaining the new React implementation of Status’ design system
- Collaborating with other people across the teams (QA, other developers, ui/ux, product, etc.)
You ideally will have:

- Thoughtful and pragmatic problem-solving
- 5+ years of software engineering experience, with 3+ years of experience with React
- Experience writing modern, performant, and accessible React code
