Fuel is a high-performance blockchain operating system that redefines what's possible on Ethereum. By combining unparalleled throughput with the core principles of decentralization and security, our platform simplifies the development process for builders worldwide.
The Fuel Virtual Machine, with its groundbreaking state minimization and parallel transaction execution capabilities, sets a new standard for Ethereum Rollups, overcoming existing limitations in protocol development.
Since our 2019 launch with Fuel V1, we've been focused on enhancing Ethereum's scalability. Our innovations, like the Fuel Virtual Machine and the Sway programming language, provide developers with a powerful, user-friendly environment.
We’re a passionate, intelligent, and empathetic globally dispersed team, united by a love for innovation and a commitment to shaping the future of blockchain technology—one groundbreaking solution at a time.
Role Overview
We are looking for a Senior Web3 Software Engineer to lead the development of high-performance decentralized applications (dapps) in a blockchain-native environment. You will own major product surfaces end-to-end—from frontend interfaces to on-chain integrations—collaborating closely with product, design, backend, and smart contract teams to ship secure, reliable, and intuitive experiences for traders and users.
Responsibilities
- Design, build, and maintain modern, responsive frontend applications integrated with blockchain protocols for core DeFi products like exchanges.
- Integrate with blockchain infrastructure (e.g., EVM chains, Fuel VM), wallet extensions (MetaMask, Phantom, WalletConnect), and on-chain data sources (e.g., subgraphs, indexers).
- Implement secure user flows for transactions, multi-sig approvals, cross-chain bridging, and account abstraction.
- Collaborate on API design (REST/GraphQL), RPC optimization, and indexer queries for real-time data.
- Establish frontend architecture, design systems, and Web3 best practices (testing with Hardhat/Foundry, gas optimization, reentrancy guards, accessibility).
- Review code (including Solidity/Sway), mentor engineers, and drive technical decisions on stack interoperability and scalability.
- Translate complex DeFi requirements (e.g., MEV protection, oracle feeds) into intuitive UI/UX for trading interfaces.
- Proactively identify technical debt in smart contracts or frontend, propose upgrades (e.g., account abstraction), and shape the product roadmap technically.
Requirements
- 5+ years of professional experience as a software engineer, with 2+ years in a senior/lead capacity building Web3 or blockchain applications.
- Deep expertise in modern frontend frameworks (React, Next.js, Vue) with TypeScript/JavaScript, plus Web3 libraries (ethers.js, viem, wagmi).
- Strong experience with complex, data-intensive dapps handling real-time streams (e.g., order books, AMM curves).
- Proven blockchain integration skills: Browser wallet connections and signing & on-chain interactions via providers (Alchemy, Infura) and libraries for reads/writes/calls.
- Solid grasp of web3 security (private key mgmt, blind signing risks, phishing, sandwich attacks).
- Backend experience with node services (e.g., Express, FastAPI), off-chain indexers (The Graph), and event listening.
- Proficiency in REST/GraphQL, data fetching (SWR, TanStack Query), and state management (Zustand, Redux) in volatile crypto contexts.
- Excellent collaboration in fast-paced, autonomous teams using GitHub, Linear, and Discord/Slack.
Nice to have
- Experience at a CEX/DEX (e.g., Uniswap, Fuel's O2, KuCoin integrations).
- Building trading UIs (order books, candlestick charts via TradingView/Lightweight Charts, positions, PnL calculators).
- Performance tuning for high-throughput DeFi (sub-ms latency, WebSockets for orderflow).
- Prior DeFi/fintech work with tokenomics, liquidity mining, or audited protocols.
- Design systems (e.g., RainbowKit, Wagmi connectors) and tooling (Vite, esbuild, Foundry for E2E tests).
What we offer
- High-impact ownership building dapps at the web2/web3 boundary, like on-chain exchanges and market-making tools.
- Autonomy to architect full systems, from UI to smart contracts and off-chain bots.
- Collaborative team with deep blockchain expertise, focused on Fuel Network and DeFi innovation.

How do I get a job at DeFi?
Getting a job in the DeFi (decentralized finance) industry can be a competitive process, but there are a few steps you can take to increase your chances of finding a job in this field:
- Build up your skills and knowledge: To work in DeFi, you'll likely need to have a strong understanding of blockchain technology, as well as other related technologies such as smart contracts and cryptocurrency. Consider taking online courses or earning a degree in a relevant field to build up your skills and knowledge.
- Network with industry professionals: Attend meetups and conferences related to DeFi and make connections with professionals in the industry. Networking can be a valuable way to learn about job openings and get your foot in the door at a DeFi company.
- Create a strong online presence: Many DeFi companies will look at your online presence (such as your LinkedIn profile and personal website) when considering you for a job. Make sure to showcase your skills and accomplishments online and keep your profile up to date.
- Apply for relevant job openings: Keep an eye out for job openings at DeFi companies and apply for positions that align with your skills and experience. Apply for DeFi Jobs without Experience. Tailor your resume and cover letter to the specific job you're applying for and highlight any relevant experience or skills you have.
- Consider internships or volunteer work: DeFi Internships or volunteer work can be a great way to get your foot in the door and gain valuable experience in the DeFi industry. Many companies also offer internships to students, so consider applying for an internship if you're still in school.
- Be persistent: keep trying if you don't get a job right away. It can take time to find the right opportunity, but with the right skills and determination, you can land a job in the DeFi industry.
