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 (IE) builds on top of.

We're hiring a mid-level Backend 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. You'll spend your time roughly between platform-layer feature work (services, jobs, framework improvements), production reliability (on-call rotation, incident response, dependency hygiene), and integration-adjacent infrastructure (proxy pools, browser fleet, identity/auth tooling).

This is a hands-on builder role on a small, high-leverage team.

Pinwheel is a hybrid environment, with a 3-day in-office requirement here in our NYC headquarters, near Union Square.

• 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

• 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, and the operational instincts that come with it (latency, retries, throttling)
• Possess solid systems-design fundamentals. You can scope a small service, reason about failure modes, and defend tradeoffs in design review
• AI-enhanced development: you've meaningfully integrated AI-assisted engineering (Claude Code, Copilot, agentic tooling) into your workflow and have opinions about where it helps vs. hurts
• Comfort with concurrency and async patterns such as threads, gevents / greenlets, async / await, or equivalent

• Browser automation: Selenium, CDP (Chrome DevTools Protocol), Playwright
• Browser fingerprinting work: TLS fingerprinting (JA3), header / User-Agent analysis, captcha challenges (Turnstile, reCAPTCHA, Arkose), residential or datacenter proxy management
• Identity protocols at a working level: OAuth2, SAML, OIDC, MFA orchestration (Okta, Microsoft Entra, PingOne, Duo, ID.me)
• FastAPI, Redis, Celery, gRPC in production
• Fintech, payroll, or other regulated environments

At Pinwheel, we are committed to building an environment that is diverse and inclusive. We believe that having people across different backgrounds, experiences, abilities, and perspectives enables us not only to build the best financial products, but to help us realize the best versions of ourselves. Pinwheel is an equal opportunity employer, and we aim to be an open and supportive place to work.
