Résumé du poste

Usual is seeking a Subgraph Engineer to advance our USD0++ ecosystem. You will build Subgraphs for DeFi integrations, track user positions across protocols, and collaborate with the team to align with tokenomics and product goals.

You bring 3+ years in DeFi, strong The Graph and AssemblyScript skills, and familiarity with Solidity. Join a small, fast-moving team building next-gen stablecoins and on-chain revenue sharing.

Qualifications

• 3+ years experience in DeFi, ideally in startup or high-growth environment.
• Proficiency with The Graph and AssemblyScript (TypeScript experience also valued).
• Solid understanding of widespread DeFi mechanics and smart contract patterns.
• Familiarity with Solidity to understand EVM smart contracts.

Responsabilités

• Research smart contracts from third-party protocols and document events related to USD0++ flow.
• Write technical specs for tracking upcoming products based on incentivization models.
• Build new Subgraphs in AssemblyScript for new integrations and extend existing ones.
• Monitor third-party protocols to keep Subgraph integrations up to date.
• Help debug and fix discrepancies between observed rewards and models.
• Assist frontend, backend, and smart contracts teams with indexing data for off-chain logic.
• Optimize performance, reliability, scalability, and security; write tests.
• Review code in PRs related to your area of expertise.
• Collaborate with BD and Tokenomics to align with future integrations and models.
• Propose continuous improvements in architecture and dev processes.

Description du poste

About Usual

Usual was born from a simple observation: dominant stablecoins operate like centralized banks - they capture bilions of revenue and don’t redistribute it. In parallel, most crypto tokenomics have failed to deliver long-term fairness, favoring insiders over users. We’re here to change that. By turning users into stakeholders, we’re pioneering a new, more equitable financial infrastructure - one where value flows back to the community. In just a few months, we built and launched a full protocol from scratch, introduced a new kind of stablecoin backed by tokenized US Treasuries (USD0), its yield-bearing counterpart (USD0++), and a revenue-sharing governance token ($USUAL). The protocol quickly reached $1.8B in TVL before stabilizing around $800M during a period of major product and governance upgrades. We’re a small, highly committed team of DeFi natives with a strong execution track record and a deep ambition to reshape how value circulates in crypto. Joining Usual means working at the frontier of decentralized finance, owning your scope, moving fast, and collaborating with some of the best minds in the space.

The Team

Our tech team is a dynamic group of 5 smart contract developers and 3 full-stack developers focused on dApp and smart contract integration. We are currently seeking an experienced Subgraph Engineer to join our talented team and contribute to the development of the protocol and the dApp.

Your Role

We’re looking for a skilled Subgraph Engineer with strong DeFi understanding to help build our continuous $USUAL rewarding system. Given new and future products we would like to integrate, you will research and develop tracking for the involved protocols and markets in order to track user positions in USD0++ across DeFi. Integrations to track include lending markets (e.g. Morpho, Euler, Sturdy), liquidity pools (e.g. Curve, Uniswap, Balancer), vaults (e.g. EtherFi, Lagoon, Origami), and many others (e.g. Pendle, Equilibria, Level). This is not a full-stack role-your focus will be on Subgraph integrations.

• Research smart contracts from third-party protocols with their help, and document the events related to the flow of USD0++ in their product.
• Write technical specifications for tracking upcoming products based on a desired incentivization model (e.g. proportional to nominal USD0++, $ of LP, boosts, fees…).
• Build new Subgraphs in AssemblyScript for new integrations and extend existing ones for new incentivised features.
• Monitor latest changes on third-party integrated protocols to ensure our Subgraph integrations are always live and up to date.
• Help debug and fix any discrepancy between observed rewards and economic models.
• Assist the rest of the tech team (frontend, backend, smart contracts) with indexing additional data required for off-chain business logic (yields, rewards, orderbooks…).
• Optimize performance, reliability, scalability, and security of the system as we grow including by writing tests (unit tests, integration tests, end-to-end tests…).
• Review code in Pull Requests from other members of the tech team related to your area of expertise.
• Collaborate with the Business Development team to assess future integrations. Align with the Tokenomics team to ensure rewards distributions correspond to models. Sync with the rest of the tech and product teams on delivery timelines.
• Propose continuous improvements in architecture, stack, and dev processes.

You Have

• 3+ years experience in DeFi, ideally in a startup or high-growth environment.
• Proficiency with The Graph and AssemblyScript (TypeScript experience also valued).
• Solid understanding of widespread DeFi mechanics and smart contract patterns.
• Familiarity with Solidity to understand EVM smart contracts (Vyper also appreciated).
• Ability to investigate and work autonomously.
• Bonus: experience in reverse engineering or ethical hacking.

Why Join Usual

• Join one of the fastest-growing protocols in DeFi.
• Build the financial primitives of tomorrow with a small, elite team.
• Work on cutting-edge DeFi projects that have a real impact.
• No red tape, no middle layers-you ship.
• Competitive salary and token options.
