Join Pinwheel, a leading fintech company, as a Senior Backend Engineer. In this role, you will own AI-driven, platform-level problem spaces, drive systems design for new integration infrastructure, and lead projects staffed with junior and mid-level engineers. You will collaborate closely with the Integrations Engineering team and adjacent teams to ensure platform primitives meet real consumer needs. Enjoy a hybrid-first work model, unlimited PTO, and a range of benefits including full medical, dental, and vision coverage, 401K, and mentorship opportunities.

Responsibilities

  • Identifying categories of recurring problems, designing systems that eliminate them, and leading the execution alongside junior and mid-level engineers.
  • Owning platform initiatives end-to-end, including scoping, designing, building, shipping, and maintaining.
  • Driving systems design for new integration infrastructure, including services, queues, data pipelines, and async workflows.
  • AI-forward thinking: you have set yourself apart from others in willingness to drive AI projects forward
  • Strong systems design: your designs get adopted by peers; you can defend tradeoffs and anticipate failure modes

Requirements

  • 5+ years of backend engineering experience
  • Demonstrated autonomous project leadership: examples of owning ambiguous, multi-quarter projects from idea to business outcomes
  • Computer Science degree or comparable experience

Browser fingerprinting / detection work

  • Experience designing and operating services that handle concurrency, failure modes, and meaningful scale
  • Experience with backend platform / infrastructure: services, queues, data pipelines, async processing
  • Experience working in Fintech or comparable regulatory environment
  • Expertise in Python
  • Track record of reducing oncall noise

Preferred

  • Integrations experience: you've built against third-party APIs, dealt with auth flows, rate limits, and the operational reality of depending on external systems
  • Browser automation experience (Selenium, CDP, Playwright): useful context for our integration surface
