• Cover libraries with unit and type-level tests; keep the public API stable and regression-safe 
• Leverage AI-assisted tools to accelerate development workflows 
• Participate in code reviews and contribute to internal engineering standards 

Requirements 

• 7+ years of commercial experience in front-end development 
• Proven experience building and maintaining TypeScript libraries/packages consumed by other teams

• Understanding of access-control models (RBAC / ABAC) 
  Experience with AI-assisted development tools (Claude Code, Codex, Cursor, etc.) 
• Upper-Intermediate level of English or higher 
• Self-motivated, proactive and detail-oriented 

We Offer:   

• Innovation Culture: Work in a team that actively experiments with AI and modern development approaches   
• Real Product Impact: Direct collaboration with a client and influence on product decisions
