Backend Engineer (Integrations Platform)

• 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
• 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

• Production operations experience: you’ve been on an on-call rotation, debugged real incidents, and shipped fixes under time pressure
• Strong Python skills (or comparable language with a clear path to ramping on Python 3.10+)
• 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
• Working knowledge of AWS. Experience with one of DynamoDB, S3, IAM, ECR, and the operational instincts that come with it (latency, retries, throttling)
• Computer Science degree or equivalent practical experience
• Possess solid systems-design fundamentals. You can scope a small service, reason about failure modes, and defend tradeoffs in design review
• 3-5 years of backend integrations engineering experience building production services
• 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
