About GFX Labs

At Oku, we aim to close the gap between the CeFi and DeFi trading experiences. It is no mistake that 95% of crypto trading occurs on centralized platforms like Binance and Coinbase since their organizations have spent substantially more time and resources investing in their trading interface, while DeFi has primarily been focused on infrastructure and protocols for the last several years.

However, that is going to change soon. While CeFi organizations enjoy their Web2 stack, a Web3 company like Oku can leverage the composability of the DeFi ecosystem and blockchain technology to offer a high-quality trading experience that will eventually be indistinguishable from CeFi and, in the long run, overcome their legacy systems. That is why Oku has 50+ partners in or supporting the app.

Oku initially started as a project within GFX Labs after they received a $1.6M grant from the Uniswap Foundation in October 2022 to build and launch a reimagined trading interface, analytics platform, and API for Uniswap v3. After ten months of development, Oku launched in July 2023, and since then, Oku has supported the DAO Uniswap’s efforts to expand across new blockchains.

Today, our primary feature is our smart order routing system, which integrates 12+ order routing systems to ensure all users find the best price possible. We have also adapted our order routing technology to offer a bridge aggregator with 11+ integrated bridges. Most recently, to close the CeFi/DeFi gap further, we added on/off-ramping with USD and EURO to our interface at an industry-low fee of free! Our other popular features include trustless onchain limit orders built directly on Uniswap v3, our position manager page for users who want to manage their LP positions, and our Uniswap v3 analytics.

Over the coming years, Oku will be expanding the scope of our offering and improving the quality of our user experience.

Why work at Oku?

Any firm can pay a high salary and offer good incentives (as will we), but most can’t offer interesting, challenging, and rewarding work.

We have something to prove. Our team is young and hungry. We like to move fast and make things. We know when to double down and when to cut our losses. We are going to make mistakes, and we are going to build a better product because of them. We don’t micromanage or have a huge team of product managers. We want self starters who take charge and solve problems.

We don’t care if you went to school, what grades you got, or your age. Show us what you have built, what problems you have solved, and what skills you have.

About the role

As a Software Engineer at Oku Trade, you’ll work alongside our engineering team to maintain and improve both our backend services and frontend applications. This role offers the opportunity to work on meaningful projects with real impact while growing your skills across our technology stack.

You’ll contribute to core components of our platform, including APIs, data processing routines, blockchain indexing, on-chain interactions across EVM chains, and React-based user interfaces.

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
