Senior Software Engineer

Role overview Investigate how websites detect and block automated access, then turn findings into reliable methods for diagnosing and addressing those barriers. You will help build a new testing environment that can systematically examine anti-bot behavior, working independently on difficult problems while sharing findings with senior engineers. Early work includes learning the systems, contributing to the environment’s design, and developing it into a tool that can analyze blocks and the signals involved.

Responsibilities - Analyze how bot mitigation systems identify and block traffic, and develop approaches to address those mechanisms. - Use a disciplined cycle of hypotheses, controlled tests, evidence review, and iteration to make results repeatable. - Collaborate with senior engineers to design and build an automated environment for testing anti-bot behavior and potential workarounds. - Work independently on complex investigations while drawing on expertise across the engineering team. - Communicate plans and findings clearly, and contribute technical depth during major incidents.

Requirements - Deep knowledge of web protocols and browser behavior, including HTTP, TLS, fingerprinting, proxies, headers, and cookies. - Strong analytical skills and a scientific, methodical approach to investigating problems. - Hands-on experience with Node.js and TypeScript, plus solid Python skills. - Familiarity with backend systems and tools such as PostgreSQL, Redis or Valkey, MongoDB, browser automation, and Kubernetes. - Ability to guide AI coding agents precisely and assess the quality of their output. - Relevant depth from scraping, web security, reverse engineering, or research; direct scraping experience is helpful but not essential. - Independence and clear communication in a remote team.

Benefits and work setup - Fully remote work with flexible location and schedule. - High autonomy, limited bureaucracy, and team support for complex work. - Flexible time off and access to a peer network for sharing knowledge.
