Senior Staff Engineer - High-Speed Validation & Signal Integrity

Location: Bristol, UK 
Hybrid: Office: Monday – Thursday

Our Team

Fancy being at the sharp end of how the world actually connects? Join an ambitious and collaborative engineering team at the cutting edge of global data communications.

Based in Bristol, we work closely with a world-renowned design group to develop advanced semiconductor solutions that power the digital infrastructure of tomorrow. Our culture is open, inclusive, and driven by innovation. 

Here, your ideas matter, your expertise is valued, and your work has a real-world impact — on the chips inside the networks that move the world’s data.

Job Summary

Think you’ve seen it all in the lab? This role will put that to the test.

As a Senior Staff Engineer – High-Speed Validation & Signal Integrity, you won’t just be running test plans someone else wrote — you’ll be shaping how next-generation semiconductor devices get validated before they ever reach the hyperscale data centres and networks that depend on them. 

This is deep, technically demanding work at data rates of 10Gbit/s and beyond, where the margin for error is measured in picoseconds and the stakes are measured in billions of connected devices.

No two days will look the same: one week you’re in new product design meetings, driving the test strategy for a device that doesn’t exist anywhere else in the world yet; the next you’re elbow-deep in the lab, pulling real signal integrity data out of silicon that’s pushing the boundaries of what’s physically possible.

You’ll have the technical credibility to be heard in the room, the autonomy to own your validation solutions end-to-end, and the kind of influence that shapes not just how a product is tested — but how it’s designed to be testable in the first place. 

If you’re the engineer other people come to when something doesn’t make sense in the data, this is where that expertise finally gets the platform it deserves.

This is senior-level validation work for someone who wants to lead from the bench, mentor the next generation of engineers, and help define the technologies the world will be running on for the next decade.

Responsibilities

• Drive test feature development and strategy in new product design meetings, shaping how next-generation devices get evaluated
• Architect validation solutions for new products end-to-end — software, hardware, and documentation
• Identify and specify the bench-top test equipment needed to validate cutting-edge products
• Build sophisticated test automation software using Python or LabVIEW
• Collaborate closely with designers, product, test, and applications engineers as a trusted technical voice
• Lead validation review meetings and influence key product decisions
• Produce clear, authoritative validation reports that others rely on
• Get hands-on testing high-speed optical components, ICs, and modules at the bleeding edge of the industry
• Take precision lab measurements on products operating at data rates of 10Gbit/s and above
• Apply deep, hard-won knowledge of high-speed signal integrity to schematic entry and layout using Altium PCB tools

Minimum Qualifications

• BSc/MSc in Electrical/Electronic Engineering (EE/ECE) or a closely related discipline (or HNC/HND with equivalent work experience)
• 6+ years of relevant experience in high-speed validation or lab-based test engineering
• A proven ability to thrive under pressure in a fast-paced, high-stakes R&D environment
• A natural collaborator who elevates the people around them
• Excellent interpersonal and communication skills, able to influence across technical and business audiences
• A relentless self-starter, comfortable mastering new tools and techniques independently
• Sharp analytical and problem-solving instincts, with an obsessive attention to detail
• A creative, innovative approach to engineering challenges others might walk away from

Why Join Us?

• Work on products that quite literally power the infrastructure connecting the world — from hyperscale data centres to 5G and PON networks
• Join a world-class validation team where your technical judgement genuinely shapes product direction
• Be part of a global organisation big enough to offer real international scope, yet agile enough for your individual impact to be felt and recognised
• Collaborate with some of the sharpest engineering minds in the industry, across Bristol and our international partner sites
• Enjoy a competitive, pay-for-performance compensation package that rewards the expertise you bring to the table
