## 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. ## Core Qualifications (Required) - 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. ## Preferred Qualifications - 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. ## Skills & Tools - **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 ## How to Apply Submit your resume and a brief cover letter highlighting relevant stablecoin or blockchain experience.
