The role

Raydar is recruiting for this role on behalf of our client. Serve as the lead backend engineer for an early-stage software platform, owning system design, reliability and delivery across a range of high-stakes services. The work spans real-time data processing, transaction handling and payment flows, with broad architectural influence from day one.

What you'll do

- Own the full backend, including APIs, database design, access controls, backups, staging environments, monitoring and deployments.

- Build and operate a real-time pricing service that collects data from several sources on a frequent schedule and routes requests to the best option.

- Manage data flowing in and out of a third-party processing system where errors have immediate real-world consequences.

- Design and build an in-house processing engine, validating it against the existing system using replayed production traffic until results match.

- Own payment infrastructure for incoming and outgoing fund flows, meeting strict uptime targets.

- Make foundational architecture and schema decisions so the platform scales smoothly as usage grows many times over.


Requirements

What we're looking for

- 3+ years of backend engineering experience with strong architecture skills.

- Experience owning production systems where downtime or errors directly affect revenue, such as payments, ledgers, trading or critical infrastructure.

- Background in backend-focused full-stack work, system architecture and database schema design.

- Comfort working as the sole engineer in an early-stage startup environment.

- Proficiency with AI-assisted development tools.

- Confidence to challenge technical decisions and give candid pushback to a strong-minded founder.

- Ability to work in person from the New York office.

- A computer science or related degree is preferred.

Bonus points

- Experience at a well-regarded fintech or infrastructure startup.
