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.
