Sobre a oportunidade
About the role We are looking for a Senior TypeScript Engineer to take technical ownership of an application-protection product as the sole engineer on the codebase. This person moves from high-level product goals to researched, working features, investigating browser runtime behavior and build environments. Comfort supervising AI-assisted development and verifying results independently is essential. What you will do Own JSDefender's technical development, moving from high-level product goals to researched implementation options and working features. Develop application-protection capabilities across JavaScript/TypeScript frameworks and build environments, rather than focusing on one front-end framework. Investigate browser runtime behavior and protection approaches, including developer-tools inspection and environment-access controls, while evaluating compatibility, performance, and protection trade-offs. Potentially contribute to the new React/Electron Dotfuscator UI during the initial months. Run short research spikes, typically one to three days as agreed during refinement, and present options, findings, risks, and recommendations to the lead architect and team. Use Claude Code to accelerate implementation while checking generated code and validating behavior; do not treat an AI response as a verified technical conclusion. Communicate progress and blockers through Slack without waiting for the next daily meeting. Publish a working schedule, remain reliably reachable within it, and communicate planned absences. Contribute to adjacent CI/CD, front-end, or C++ package work when needed, using research, AI assistance, and collaboration rather than assuming expertise in every stack. Must haves Strong hands-on TypeScript engineering skills, with at least 3 years of experience, and demonstrated ability to own technical delivery independently. Experience length alone does not establish readiness for sole-engineer product ownership. Strong understanding of JavaScript/TypeScript behavior, browser execution, and the build ecosystem, including tools such as Webpack or Vite; experience with every framework or tool is not required. A product-engineering mindset: make progress from incomplete requirements, investigate unknowns, compare options, and seek alignment on consequential decisions rather than waiting for fully specified tickets. Critical thinking, clear technical communication, and the ability to ask useful follow-up questions of teammates and AI agents. Ability to review unfamiliar code, identify defects and potential vulnerabilities, explain trade-offs, and verify AI-assisted implementations. Availability for European team overlap and agreed scrum meetings, with dependable asynchronous communication during the declared working schedule. Upper-intermediate English level. Nice to haves React and Electron experience for desktop application interfaces. Node.js experience; familiarity with Angular, Vue, or Rollup. Experience with obfuscation, runtime protection, browser internals, or developer tools integrated into build workflows. Experience integrating native C++ packages or maintaining CI/CD workflows. Perks and benefits Growth without limits: build your skills through mentorship, internal TechTalks, challenging projects, and a dedicated annual learning budget Competitive compensation: get recognition that reflects your skills and impact, with regular performance and compensation reviews Flexibility: work 100% remotely with flexible hours that support focus, autonomy, and a healthy work rhythm Meaningful, modern projects: build impactful products using modern technologies alongside global teams and leading brands Collaborative culture: join a supportive environment with zero micromanagement where ideas are welcomed and contributions are recognized Well-being & support: access local well-being programs and people-focused support tailored to your location Job Type: Full-time Work Location: Remote
