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    Define and own the end-to-end GNSS receiver software architecture, including acquisition, tracking, measurement engine, navigation, and positioning stack.

Lead architectural decisions for low-power, high-performance GNSS chipsets, balancing performance, power, and silicon constraints.

Translate product requirements into scalable, modular, and maintainable software architectures.

Drive design trade-offs across algorithm complexity, hardware acceleration, and system constraints.

Design and optimize advanced algorithms for: GNSS acquisition and tracking (multi-constellation, multi-frequency), Positioning, navigation, and timing (PNT), Multipath mitigation and interference suppression, Snapshot and ultra-low-power GNSS techniques

Lead development of next-generation techniques such as:
Assisted GNSS (A-GNSS), Hybrid positioning (GNSS + Wi‑Fi/Bluetooth/IMU), LEO‑PNT and emerging navigation paradigms

Oversee implementation of GNSS algorithms in embedded C on RTOS / bare‑metal systems, FPGA with focus on performance optimization, high-volume silicon deployment

Mentor and guide engineers, contractors in GNSS algorithms and embedded development. Set technical direction and promote engineering best practices, design standards and lead technical reviews, architecture discussions, decision‑making processes.

Cross‑Functional collaboration with product management to shape feature roadmap and differentiation strategy. Present technical concepts and results to internal and external stakeholders, including leadership teams and customers.

Job requirements  Must haves  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 or PhD in Electrical Engineering, Signal Processing, or related field.
