Web3 Backend Engineer

About Us 0xbow is the DeFi sector's response to the growing need for a balanced approach to privacy and regulatory compliance. We're building the next generation of privacy infrastructure for Ethereum and beyond. Privacy Pools is a groundbreaking protocol enabling transactional privacy without compromising on compliance. We believe in privacy as a public good and are committed to building tools that are secure, composable, and ready for mass adoption. As we scale, we're looking for a Backend Engineer to build infrastructure for deployments and contribute to new ASP integrations across networks. What You'll Do Develop observability tooling—logs, metrics, alerts—for relayer health, pool usage, transaction patterns, and integrity checks. Create APIs and backend services to support new ASP integrations and data pipelines. Build dashboards and alerts for anomalies, regulatory triggers, or edge-case behavior. Work closely with protocol, infra, and compliance teams to make sure monitoring supports operational and compliance needs. Contribute to automation for ASP onboarding and network-specific integration workflows. What We're Looking For Strong backend experience (Node.js, Nest.js, TypeScript, but solid engineering is key). Strong experience with SQL. Experience with GraphQL is nice-to-have. Experience with Kubernetes and microservice architecture. Experience in testing features and requirements. Solid understanding of blockchain systems and how to interface with them. Comfortable with on-chain/off-chain architecture and event-based systems. Security-first mindset: you think about failure modes and build defensively. Why Join Us? We're a small, mission-driven team with real traction and real impact. You'll work at the bleeding edge of compliance-preserving privacy. The work you do will directly influence the success of Privacy Pools across chains. Competitive compensation, and a chance to shape the future of private, compliant finance.
