Senior Validation Engineer

Join our cutting‑edge start‑up adventure!

Who are we?

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.

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.

As a Sr. Silicon Validation Engineer, you will be responsible for developing, implementing, and executing test plans to ensure the functionality and performance of SOC integrating Digital, Analog and RF components. This role requires hands‑on experience in debugging, analyzing, and characterizing SoCs through automated test setups.

• Collaborating closely with the design teams, firmware, and software teams to define digital test requirements and validation plans.
• Developing and executing comprehensive test plans to validate all digital functionalities.
• Working on SoC‑level validation and bring‑up, managing tests from component‑level through to full system operation.
• Creating Python/C scripts to automate tests and collect measurements using automated setups with digital test equipment.
• Collecting, organizing, and analyzing data to verify performance across various conditions for different samples.
• Utilizing tools like Python for scripting and data handling to automate processes and enhance analysis.
• Debugging and troubleshooting issues that arise during testing, including hardware, firmware, and digital interface issues, and collaborating with design, applications, and software teams to implement solutions.
• Documenting test procedures, validation results, and specifications for internal reference and compliance.

The ideal candidate for this Digital Validation Engineer role is detail‑oriented, proactive, and has a can‑do attitude, with the following qualifications:

• BSc or MSc in Electrical Engineering, Embedded Systems, or a related field.
• Strong knowledge of digital circuits, including memory and MCU architecture and digital interfaces, with experience in low‑power IoT systems.
• Hands‑on experience with bus protocols (AHB, APB) and peripheral interfaces (SPI, I2C, UART).
• Working knowledge of FPGA systems for pre‑silicon debugging, especially Zynq processors.
• Proficiency in firmware debugging and real‑time troubleshooting using debugging tools and creating mini‑fw to test the HW.
• Experience with automated test setups and conducting concurrent lab tests on multiple products.
• Hands‑on experience with lab equipment, such as oscilloscopes, logic analyzers, digital multimeters, signal generators, and programmable power supplies.
• Proficiency in Python programming for…
