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.

Borne 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.

Role Overview
As a Senior System-Level Designer, you'll play a pivotal role in designing the digital baseband part of our cutting-edge GNSS/IoT chip. This role is for those who enjoy challenges and wish to contribute to the development of technology that powers GNSS L1/L5 receivers and BLE/Lora/NB-IoT transceivers.

As a  Senior Communication System Engineer , you will help shape the future of our next-generation products. You will be responsible for the design and implementation of advanced communication systems, contributing to both innovation and performance optimization.

Key Responsibilities

Design and implement communication systems with a focus on bandwidth, latency, reliability, and power efficiency.

Develop innovative algorithms and solutions to address challenging system-level problems.

Analyze standard requirements (e.g., BLE, LTE) and benchmark competitor performance to guide strategic design decisions.

Collaborate with cross-functional teams including hardware, software, and network engineers to ensure seamless system integration.

Work closely with RTL implementation teams to support fixed-point modeling and ensure efficient FPGA/ASIC realization.

Develop and execute test plans to validate system performance and reliability.

Maintain comprehensive documentation for system designs, configurations, and troubleshooting procedures

Requirements
We’re looking for a result-driven engineer who thrives in a proactive, collaborative environment. The ideal candidate will have:
