Staff Software Engineer (Cloud/Backend)

O projekcie At D-Fend Solutions - now proudly part of the Motorola Solutions family - our people are our greatest strength, and technology is our passion. As the global leader in cyber-takeover counter-drone technology, we design and deliver advanced, software-defined solutions that empower our customers to detect, take control, and safely land unauthorized drones.

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.

Job Description

We are building a powerhouse Cloud/Platform team in Krakow, and we are looking for a Staff Software Engineer to be a part of this group. You will play a crucial role in architecting, implementing, maintaining, and scaling a massive multi-tenant SaaS distributed ecosystem, migrating on-premise components into a modern cloud architecture. You will partner closely with our Architecture team to shape the technical direction, acting as the ultimate subject matter expert (SME) for Node.js.

We are looking for a highly adaptable, heavyweight engineer who is "hot on code" and loves being deeply hands-on.

As a Staff Engineer in this elite team, you must be

• Highly Adaptable: Completely comfortable and highly effective in a rapidly changing, dynamic environment.
• A Fast Learner: Able to quickly absorb new domain knowledge and master new technologies on the fly.
• Decisive: Capable of making quick, pragmatic, and highly technical decisions without getting stuck in analysis paralysis.
• A Team Player: Ready to collaborate effectively with top-tier engineers, sharing knowledge, and driving collective success.
• A Technical Influencer: You elevate the team's engineering standards by example, providing technical guidance, prototyping architectural solutions, and acting as a sounding board for complex design decisions.

(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).

• The Core Stack: Expertise in Node.js and TypeScript (including frameworks like NestJS or Express). You are highly hands-on and write extremely clean, scalable code.
• Cloud & Observability: Strong experience designing and building event-driven microservices in a major cloud provider (AWS, Azure, GCP) and implementing modern Cloud Observability patterns (metrics, distributed tracing, structured logging).
• Data & Infrastructure: Solid proficiency with relational databases (PostgreSQL), in-memory caching (Redis), and containerized environments (Docker, Kubernetes).
• End-to-End Ownership: Practical experience with (or a strong willingness to touch) React to help the team deliver complete, end-to-end features when necessary.

Big Advantages (Bonus Points)
