In this position, you will take on architectural and design responsibility for the platform layer bridging a mature core system and new applications. You will draft and implement backend services, APIs, and scalable infrastructure for a product in daily real-world use, while helping actively shape team structures and technical processes from the ground up.

Design and develop resilient backend systems and API endpoints for our central platform.

Define and substantiate technical architecture and design choices for upcoming system modules.

Regularly improve, scale up, and tune current services alongside the core platform infrastructure.

Assume full technical responsibility for operational performance, reliability, and deployment processes in production.

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.
