We’re looking for a Senior Frontend Developer who will own and evolve the frontend architecture of our Portal – a modular, microfrontend-driven platform supporting merchants across logistics, payments, returns, and beyond.

This is a hands-on leadership role, combining deep technical expertise with architectural ownership and cross-team collaboration. Your main frontend weapon is Angular, which you know in-depth – both in implementation and architecture. You’re also comfortable navigating React environments and understand its patterns and ecosystem. You bring strong knowledge in E2E testing using Playwright and believe quality and developer experience go hand-in-hand.

• Collaborate with UX and product designers to deliver globally consistent experiences.

III. Collaboration with Product Teams:

• Act as a platform consultant to product engineering teams.

• Deep understanding of microfrontend architecture and frontend infrastructure.
• Comfortable working in large-scale systems with multiple teams consuming shared code.
