About the Role

We are looking for a high-calibre Senior Full Stack Engineer to join a product-focused team, building and iterating on modern applications in a fast-paced environment.

This role goes beyond traditional full-stack development. It is suited for engineers who combine strong technical fundamentals with product thinking, high ownership, and the ability to move quickly while maintaining quality. You will work across the stack, prototype rapidly, and leverage AI tools as a core part of your daily workflow.

The ideal candidate is an independent thinker who can operate with minimal direction, challenge assumptions (including AI-generated outputs), and deliver end-to-end solutions. This is a highly visible role requiring strong communication skills and the ability to engage confidently with senior stakeholders.
