Sr. Silicon Validation Engineer

Building the Future of GNSS & IoT Connectivity

Our client is a pioneering semiconductor scale-up developing innovative technology for the next generation of connected devices.

The company is transforming how devices connect, communicate and operate through advanced Digital RF technology, with a particular focus on ultra-low-power GNSS and intelligent IoT connectivity.

Founded from deep-tech research at a leading European technical university, the team brings together highly experienced engineers, researchers and technology specialists working on some of the most challenging problems in GNSS, IoT and low-power semiconductor design.

The company's ambition is to develop highly efficient, adaptive and scalable connectivity solutions capable of powering billions of connected devices across a wide range of applications.

The Opportunity

We are looking for a Senior Silicon Validation Engineer to join the team and take responsibility for developing, implementing and executing validation strategies for complex SoCs integrating digital, analogue and RF technologies.

This is a highly hands-on role focused on SoC bring-up, debugging, characterisation and automated validation.

You will work closely with digital design, firmware and software teams to develop comprehensive validation plans, build automated test environments and investigate issues across hardware, firmware and digital interfaces.

Key Responsibilities

Define digital test requirements and validation strategies in collaboration with design, firmware and software teams

Develop and execute comprehensive test plans covering digital functionality

Lead SoC-level validation and silicon bring-up, from component-level testing through to full system operation

Develop Python and C/C++ scripts to automate testing and data collection

Build and maintain automated test setups using digital laboratory equipment

Collect, organise and analyse validation data across multiple devices and operating conditions

Characterise SoC performance and identify potential hardware or firmware issues

Debug and troubleshoot hardware, firmware and digital interface problems

Work cross-functionally with design, applications and software teams to identify root causes and implement solutions

Develop firmware or mini-firmware where required to exercise and validate hardware

Document validation procedures, results, specifications and technical findings

Support the continuous improvement of automated validation processes and methodologies

Technical Requirements

The ideal candidate will have a strong background in digital silicon validation and embedded systems, with hands-on laboratory experience.

You should have:

BSc or MSc in Electrical Engineering, Embedded Systems or a related discipline

Strong understanding of digital circuits, including memory, MCU architectures and digital interfaces

Experience with low-power IoT systems

Hands-on experience with bus protocols such as AHB and APB

Experience with peripheral interfaces including SPI, I2C and UART

Working knowledge of FPGA systems for pre-silicon debugging, particularly Zynq

Strong firmware debugging and real-time troubleshooting skills

Experience developing small firmware applications to test and exercise hardware

Experience with automated silicon validation and test setups

Ability to conduct and manage concurrent laboratory testing across multiple products

Strong practical experience with laboratory equipment, including

Logic analysers

Digital multimeters

Signal generators

Programmable power supplies

Strong Python programming skills for test automation and data analysis

Familiarity with Git, Excel and database management

Nice to Have

The following experience would be advantageous:

Knowledge of GNSS technologies

Experience working on location-based IoT products

Power, Voltage and Temperature (PVT) characterisation

Experience with analogue hardware testing

Broader experience across mixed-signal SoC validation

What You’ll Bring

We're looking for someone who is hands-on, analytical and proactive, with a genuine interest in understanding how silicon behaves in real-world conditions.

You’ll be comfortable moving between the lab, software and hardware, investigating unexpected behaviour and working with multidisciplinary engineering teams to find practical solutions.

The ideal candidate combines strong technical fundamentals with a can-do attitude, attention to detail and a methodical approach to debugging and validation.

What’s on Offer

Employee equity – share in the success of the company as it grows

Well-being support – access to wellness resources and mental health support

Relocation support – assistance with the visa process for international hires

Pension contributions – support for your long-term financial planning

Modern workspace – a vibrant, well-equipped engineering environment

Scale-up culture – a collaborative team environment with regular company events and celebrations

This is an opportunity to join an ambitious deep-tech semiconductor scale-up and play a key role in validating the silicon behind the next generation of connected and low-power IoT devices.
