ME & DSP Engineer

Join our cutting-edge start-up adventure!

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 optimize algorithms for GNSS acquisition, tracking, and measurement engines to achieve best-in-class performance.
• Implement and validate algorithms on embedded platforms using C in real-time operating systems.
• Develop simulation models (floating-point and fixed-point) to analyze system performance and guide design decisions.
• Create robust software tools in MATLAB and Python for algorithm development, testing, and automation.
• Develop hardware-in-the-loop (HIL) test frameworks to continuously verify and validate firmware performance.
• 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.

Job requirements

Qualinx is looking for a result-driven and conscientious GNSS Engineer. Someone who thrives in an environment where your proactive and can-do attitude is highly appreciated. The ideal candidate for this role must have:

• Master’s degree in Electrical Engineering or equivalent industry experience, with 3+ years of hands‑on GNSS testing experience.
• Strong knowledge of the GNSS and communication system processing chain.
• Strong Matlab/ Python and C programming skills.
• Experience with DSP algorithm implementation in real-time (chipset on embedded platform).
• Excellent communication and presentation skills in English.

Nice to have

• In-depth knowledge of GNSS acquisition, tracking, and navigation algorithms, as well as familiarity with DSP and RF concepts commonly used in communication systems.
• Multipath and interference mitigation techniques (at measurement or positioning engine level).
• Solid understanding of RF laboratory setups, including RF distribution, LNAs, splitters, and attenuators.
• Familiarity with SDR development and RFCS simulators.
• Experience with CI environments (e.g., GitLab) for automated testing.
