Who are we?

Join the Revolution in GNSS and IoT Connectivity

At Qualinx, we’re not just building chips, we’re engineering the future fabric of the connected world. As a pioneering semiconductor scale-up, we’re transforming how devices connect, communicate, and operate through our ground-breaking Digital RF technology. Our mission goes beyond ultra-low power GNSS: we’re redefining what’s possible in adaptive, scalable, and intelligent connectivity for the Internet of Things.

Born from deep-tech innovation at TU Delft, our team of visionary engineers and bold thinkers is tackling the toughest challenges in GNSS and IoT, starting with power consumption and expanding into dynamic, context-aware solutions that adapt to any environment or use case. We’ve already achieved what many thought impossible: the world’s most advanced GNSS chipset. But that’s just the beginning.

At Qualinx, we believe that the future of connectivity lies in precision, efficiency, and adaptability. Our ambition is to become the invisible thread that seamlessly interconnects billions of devices: powering a smarter, more responsive world.

What Sets Us Apart

Joining Qualinx is about becoming part of a culture that’s as ambitious as it is authentic. We hold ourselves to high standards, thrive on solving the unexpected, and push boundaries together. But we also know how to enjoy the ride. Our culture is a unique blend of curiosity, team spirit, and a touch of unconventional charm. It’s fast-paced, fun, and grounded in a sober sense of purpose and perspective. Whether we’re deep in design reviews or sharing laughs over lunch, we’re building something meaningful together. At Qualinx, you’re not just contributing to a ground-breaking technology, you’re helping shape a team that’s redefining what it means to work in deep tech.

Job Description

  • Design and implement automation tools in MATLAB and Python for GNSS receiver testing and performance analysis.

  • Develop hardware-in-the-loop (HIL) test frameworks to continuously verify and validate firmware performance.

  • Create and maintain algorithms for computing GNSS Key Performance Indicators (KPIs) for multi-constellation, multi-frequency receivers.

  • Ensure the reliability of the GNSS laboratory and CI pipeline, including managing RFCS simulators (e.g., Spirent), SDRs, and RF distribution systems.

  • Monitor and safeguard GNSS system performance during algorithm development and integration phases.

  • Document and present technical findings clearly to internal teams and external stakeholders.

  • Contribute to continuous improvement by following and enhancing company software engineering best practices
