Reverse Engineer

About the role

Pinwheel is building the next generation of financial products alongside major brands such as Robinhood, DoorDash, Chime, Cash App, Credit Karma, American Express, Discover, Intuit, Acorns, Visa and more. The company has raised $77M from top-tier investors including Coatue, Notable, First Round, Upfront, Primary, American Express, Franklin Templeton, Indeed, Semper Virens and more. Pinwheel's Integrations Platform (IP) team builds the services, primitives, and tooling that make 1800+ integrations work at scale, including proxy management, browser automation, identity flows, session handling, and the runtime that every Integrations Engineer builds on top of. We're hiring a mid-level Engineer to own well-scoped platform projects end-to-end, ship reliability and performance improvements that benefit every IE, and grow into broader systems ownership. This role is hybrid with 3 days a week in our NYC office. This position does not offer visa sponsorship now or in the future.

Responsibilities

• Own platform projects end-to-end, from scoping and design review through shipping and operation
• Scraping Engineering & Research Heavy Projects: You've worked on reverse engineering problems such as integrations, scrapers, automation, or platform work against systems that are moving targets. Familiar with the rhythm of "ship a fix, monitor for changes, ship the next fix."
• Ship reliability and performance improvements to shared infrastructure (proxy management, browser fleet, on-prem infra, session/state management, latency-sensitive AWS code paths)
• Raise the floor for Integration Engineers through shared libraries, custom lint rules, internal tooling, and code review that catches systemic issues before they ship
• Apply AI-assisted workflows thoughtfully, both to your own work and to the tooling other engineers use
• Operate the platform in production: participate in the on-call rotation, triage incidents, write postmortems, and ship fixes that prevent recurrence
• Stay on top of dependency and security hygiene, including CodeQL findings, CVE remediation, TLS/crypto updates

Qualifications

• 3-5 years of backend integrations engineering experience building production services
• Computer Science degree or equivalent practical experience
• Strong Python skills (or comparable language with a clear path to ramping on Python 3.10+)
• Production operations experience: you've been on an on-call rotation, debugged real incidents, and shipped fixes under time pressure
• Working knowledge of AWS. Experience with one of DynamoDB, S3, IAM, ECR
