The Mission in Krakow: Following the acquisition, our Krakow MSI engineering center is partnering directly with the D-Fend group to drive a technological transformation: moving a critical configuration application to the Cloud. We are assembling an elite, highly agile team capable of diving deep into the existing solution, leveraging Motorola’s vast cloud expertise, and delivering high-impact results at startup speed. We’re seeking passionate, top-tier professionals who thrive in a fast-paced, creative, and collaborative environment. If you want to build cutting-edge airspace security innovation alongside the best engineers in the industry, this is your place.

The Role: We are building a powerhouse Cloud/Platform team in Krakow, and we are looking for a Senior Software Engineer to be a part of this group. You will play a crucial role in implementing, maintaining, and scaling a massive multi-tenant SaaS distributed ecosystem , migrating on-premise components into a modern cloud architecture.

(Note: While this role is heavily focused on backend engineering and cloud infrastructure, we operate with a strict 'You Build It, You Run It' culture. End-to-end ownership is key, and you will occasionally dive into the frontend (React) to deliver complete features).

Drive the Cloud Transition: Play a hands-on role in building and running multi-tenant SaaS applications designed specifically to take full advantage of cloud-native architecture. Build Distributed Systems: Implement highly complex, high-throughput backend services and distributed systems, ensuring seamless data flow across Cloud, On-Premise, and Edge layers.
