Web3 / Defi Backend Developer - senior

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.

Usual is the first stablecoin protocol that gives back the ownership and the value to its users. 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.

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 Full Stack Developer to join our talented team and contribute to the development of the protocol and the dApp.

We’re looking for a skilled Backend Developer to help scale our infrastructure and power the data and integrations behind our protocol and dApp. Working closely with smart contract, frontend, and product teams, you'll own the backend systems that provide DeFi-specific business logic, off-chain computation, and API exposure to the rest of the stack.

This is not a full-stack role—your focus will be backend-first.

• Architect and develop backend services using NestJS and serverless (e.g. GCP Cloud Run, AWS Lambda).
• Design, build, and maintain REST APIs that expose data for internal and external use (frontend, integrations, dashboards).
• Integrate with smart contracts on Ethereum and L2s via Viem and The Graph.
• Implement off-chain business logic and computation to support key protocol features (yield, rewards, simulations, etc).
• Optimize performance, reliability, and scalability of the system as we grow.
• Collaborate with the rest of the tech team (frontend, smart contracts, product) to scope and deliver product features.
• Propose improvements in architecture, stack, and dev processes.

• 3+ years experience as a backend engineer, ideally in a startup or high-growth environment.
• Proficiency in NestJS / TypeScript and understanding of clean API architecture.
• Hands-on experience with serverless environments (Cloud Run, AWS Lambda, etc.).
• Familiarity with Viem, The Graph, and interacting with EVM-based blockchains.
• A strong product mindset: you understand how backend impacts UX, and you care about building smooth user experiences.
• Bonus: exposure to Solidity, DeFi mechanics, or interest in diving deeper.

• 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.
