Backend Software Engineer
Description
About the company
Our client is a financial services company.
The role
Raydar is recruiting for this role on behalf of our client. Design and build backend services for transaction processing and financial record-keeping, owning systems from architecture through production support. The work spans checkout flows, access controls, risk checks and reconciliation, with a focus on correctness and reliability.
What you'll do
- Develop order-processing paths that carry a customer's request through to final confirmation across browser-based, protocol-based and direct API channels.
- Design secure credential storage and access boundaries so sensitive data is never exposed to downstream callers.
- Build permission, budget and approval logic, along with the user-facing tools used to configure and review it.
- Build risk detection systems for account compromise and fraudulent counterparties.
- Own reconciliation and ledger accuracy at high volume, including resolving ambiguous transaction outcomes such as timeouts.
Requirements
What we're looking for
- 3+ years of engineering experience at large-scale technology companies or a chartered bank or chartered trust, with a clear interest in joining a small, young company.
- Has built a payment processor directly, not only integrated a third-party one.
- Track record of running live backend systems independently from design through operation, including being on the hook for incidents.
- Background in platform or infrastructure work, such as developer tools, distributed systems or payment integrations at fintech companies.
- Designs for failure from the start, including timeouts, retries, idempotency and backpressure.
- Working knowledge of TypeScript and Node.js.
- Able to work on-site five days a week in San Francisco and uses AI tools day to day.
Bonus points
- Prior work on card programs, payment card data security compliance, metered billing, fraud screening, or gateway and request-routing layers.
