About The Position

Pinwheel is building the next generation of financial products alongside some of the biggest names in the market. The Integrations Platform (IP) team builds the services, primitives, and tooling that make 1800+ integrations work at scale. This role is for a Senior Platform Engineer to own platform-level problem spaces end-to-end, raise the technical bar, and make the Integrations Engineering team measurably more productive. The engineer will identify categories of recurring problems, design systems that eliminate them, and lead the execution alongside junior and mid-level engineers. Pinwheel is a hybrid environment, with a 3-day in-office requirement in their NYC headquarters.

Requirements

5+ years of backend engineering experience
Computer Science degree or comparable experience
Experience designing and operating services that handle concurrency, failure modes, and meaningful scale
Experience with backend platform / infrastructure: services, queues, data pipelines, async processing
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
AI-forward thinking: you have set yourself apart from others in willingness to drive AI projects forward

Nice To Haves

Browser fingerprinting / detection work
Expertise in Python
Experience working in Fintech or comparable regulatory environment
Track record of reducing oncall noise

Responsibilities

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
