Reverse Engineer

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

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
