• Collaborate closely with cross‑functional teams to shape product direction.

• Support hiring, performance management and technical roadmaps.

Required profile

• Extensive experience building modern frontend applications with TypeScript and Vue 3.
• Solid backend experience with Node‑based services and relational databases.
• Experience working with PostgreSQL, Prisma, AWS, and REST APIs.
