Web3 Software Engineer, Stablecoin

What You’ll Do

You will help design, build, and operate core components of a stablecoin product, spanning on-chain smart contracts and off-chain services that ensure peg stability, liquidity, and secure payments. Working closely with product, research, and security teams, you’ll own features end-to-end—from architecture and implementation to observability and incident response.

• Build and maintain smart contracts and on-chain components (Solidity, Rust, etc.) for stablecoin issuance, redemption, and peg mechanics.
• Develop and scale off-chain services (backends, payment rails, oracles) that interact with blockchains and external liquidity providers.
• Implement robust monitoring, alerting, and automated recovery for financial systems handling real funds.
• Collaborate with cryptography, research, and security teams to implement secure protocols and threat mitigations.
• Participate in design reviews, code reviews, and post-incident blameless retrospectives.
• Contribute to developer tooling, testing frameworks, and CI/CD pipelines focused on blockchain deployments.

• 3+ years building production-grade backend or distributed systems (or equivalent experience in blockchain infrastructure).
• Hands-on experience with smart contract development or strong understanding of smart-contract architecture (Solidity, Vyper, Rust, or similar).
• Proficiency with at least one backend language (Go, Rust, Python, Node.js, Java) and experience integrating with blockchain nodes / RPCs.
• Strong software engineering fundamentals: system design, testing, observability, and debugging at scale.
• Solid understanding of cryptography basics, consensus mechanics, and DeFi primitives relevant to stablecoins.
• Experience with secure coding practices and performing/participating in security audits.
• Excellent communication skills and ability to work cross-functionally.

• Prior experience launching or maintaining a stablecoin, payments platform, or other production crypto-financial product.
• Familiarity with oracle design, liquidity management, risk modelling, or peg stabilization mechanisms.
• Experience with Layer 2 solutions, cross-chain bridges, or interoperability tooling.
• Background in formal verification, fuzz testing, or running smart contract audits.
• Familiarity with cloud infrastructure (AWS/GCP), containerization (Docker/Kubernetes), and infra-as-code.
• Contributions to open-source blockchain projects or published research in crypto/DeFi.

• Smart contracts: Solidity, Rust (Ink/Anchor), Vyper
• Backend: Go, Rust, Python, Node.js, Java
• Blockchain tooling: Hardhat, Truffle, Foundry, ethers.js, web3.py
• Databases & caches: Postgres, Redis
• Observability: Prometheus, Grafana, Sentry
• CI/CD & infra: GitHub Actions, Terraform, Docker, Kubernetes
• Security & testing: unit/integration tests, fuzzing, static analysis, audit processes
