In this position, you will take on architectural and design responsibility for the platform layer bridging a mature core system and new applications.

* Serve as a key technical advisor in our growing Platform Team, guiding technical frameworks and methodologies from the very beginning.

| WHOM WE ARE LOOKING FOR

* Multi-year track record working as a Senior Backend or Full-Stack developer in a dedicated product-focused environment rather than project-based agencies.

* Deep expertise in using object-oriented languages like Java, C#/.NET, or Python.

* Demonstrated background in system architecture with a history of owning and maintaining the systems you build.

* Solid practical knowledge of designing APIs, microservices, and managing communications between distributed architectures.

Should you relocate or travel for this role, your relocation or travel costs will naturally be covered.

| WHAT YOU WILL GET
