The Role
Own the technical development of an application-protection product as its sole engineer. Build TypeScript and JavaScript capabilities across frameworks and build environments, investigate browser runtime behavior, evaluate security and performance trade-offs, conduct research spikes, review AI-assisted code, and communicate progress asynchronously. Contribute to React/Electron UI, CI/CD, front-end, and native C++ package work as needed.

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 the product'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 a new React/Electron application 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
- Professional growth: Accelerate your professional journey with mentorship, TechTalks, and personalized growth roadmaps.
- Competitive compensation: We match your ever-growing skills, talent, and contributions with competitive USD-based compensation and budgets for education, fitness, and team activities.
- A selection of exciting projects: Join projects with modern solutions development and top-tier clients that include Fortune 500 enterprises and leading product brands.
- Flextime: Tailor your schedule for an optimal work-life balance, by having the options of working from home and going to the office – whatever makes you the happiest and most productive.
