TypeScript Developer

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

• 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
