Senior Backend Engineer

Who you are

• 5+ years of backend engineering experience
• Computer Science degree or comparable experience
• 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
• Demonstrated autonomous project leadership: examples of owning ambiguous, multi-quarter projects from idea to business outcomes
• 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
• 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
• Expertise in Python
• Experience working in Fintech or comparable regulatory environment
• Track record of reducing oncall noise

What the job involves

• Ou'll identify categories of recurring problems, design systems that eliminate them, and lead the execution alongside junior and mid-level engineers
• Own platform initiatives end-to-end: scope, design, build, ship, and maintain
• Drive systems design for new integration infrastructure, including services, queues, data pipelines, async workflows
• Lead projects staffed with junior and mid-level engineers; make them measurably more productive through code review, design feedback, and the systems you build
• Identify and eliminate classes of problems rather than patching individual one off bugs
• Set technical direction in ambiguous problem spaces
• Collaborate closely with IE and adjacent teams to ensure platform primitives meet real consumer needs
