Senior Product Engineer (ReactJS + NodeJS + Typescript)

What will you be doing?

Your day-to-day responsibilities:

• Design and evolve the core architecture of our platform
• Set technical standards and take ownership of complex projects end-to-end
• Work on a well-architected, fast-evolving TypeScript codebase using technologies such as Webpack, React, Node.js, Electron, and GraphQL
• Collaborate with product managers, designers, and engineers to solve challenging technical and business problems, with real autonomy
• Participate in the full development lifecycle: scoping, design, estimation, coding, testing, debugging, code reviews, maintenance, and support
• Evaluate and implement proofs of concept using the latest AI tools and models

You will know you're successful if:

• You develop projects independently until they deliver their intended business value
• You keep top-notch software quality standards in regards to design, implementation and documentation
• You're the person who brings something new to the team's radar, a model, a technique, a tool, before anyone else has heard of it

• Excellent English (C1+) with exceptional written and verbal communication
• Strong proficiency with TypeScript or JavaScript across frontend and backend, including building and maintaining Node.js-based services
• Ability to work independently and take ownership of deliverables
• Strong technical fundamentals, genuine intellectual curiosity, and a drive to keep getting better
• You follow AI closely, not just as a user but as someone who reads the papers, watches the releases, and has opinions. You're excited about where this is going and want to be building at the edge of it
• Experience in frontend development using JavaScript and modern frameworks such as Vue.js or React
• Experience with Puppeteer or Playwright
• Familiarity with AI-coding tooling (Claude Code, Cursor, OpenCode, etc.)
