Senior Windows Engineer

Applivery is the next-generation, AI-driven Unified Endpoint Management (UEM) and app distribution platform. We empower IT and security teams worldwide to secure, automate, and scale their digital workplaces across Apple, Android, and Windows. Recognized in the Gartner® Magic Quadrant alongside giants like Microsoft, our software is trusted globally by market leaders including Mercedes-Benz, Starbucks, Snapchat, Supercell, and BNP Paribas.

We are a high-velocity, product-first scale-up. We don’t do bloated hierarchies or corporate bureaucracy; we thrive on extreme autonomy, speed, and pride in execution. Here, you won’t be a cog in a machine—every person has a direct, visible impact on our product, our culture, and our trajectory.

As we enter our next phase of hyper-growth, we are looking for builders who want to leverage AI, take extreme ownership, and help us scale a product that shapes how the world works. This is the perfect time to hop on board.

As our Windows Engineer, you will own the development and evolution of our Windows MDM agent — a desktop application that runs both in user context and at system level, handling application install and management, script execution, device information gathering, OS update management, and communication with our MDM services.

Your mission will be to build robust, device-side solutions that operate reliably across our customers' Windows fleets, working ever closer to the operating system as the product demands.

The ideal candidate is a solid Senior Software Engineer with strong backend and software architecture experience, driven by technical curiosity and eager to go low-level into Windows internals when a problem requires it. We're not looking for a Windows specialist; we're looking for a builder who takes extreme ownership, questions solutions, and thrives with autonomy. If you are driven by delivering ambitious business growth whilst changing an industry, please keep reading.
