Mobile Application Developer

Company

NestAI is Europe’s fastest-growing physical AI lab. We build open, sovereign, and reliable autonomous systems and AI-enabled command capabilities for real-world operations — environments where reliability isn’t optional.

Our work spans defence, security, and other mission-critical domains where systems must earn trust through performance, not promises. At the core of what we build is an open, modular, and interoperable AI command foundation that integrates data from multiple sources — from UAV sensors and edge devices to situational intelligence platforms — and turns it into decision support and operational capability.

Rooted in Nordic engineering heritage, we focus on openness, reliability, and systems that earn trust through performance. We work with intent, iterate fast, and build technology that protects what matters most.

• Excellent problem-solving abilities and attention to detail.

Why join NestAI

At NestAI, you’ll build meaningful, real-world technology as part of a world-class team of engineers, scientists, and experienced professionals.

If you want to build with purpose — and with leading experts in the field — you’ve come to the right place.
