Senior Staff Characterisation Engineer

Bristol, ENG, GB, United Kingdom

Job Description

Location:

Bristol Design Centre, Bradley Stoke (Hybrid Working Available)



Our Team:

Join a world-class engineering team at Semtech's Bristol Design Centre, where we're developing high-performance semiconductor solutions that enable next-generation optical access networks. As a market leader in PON ONU chipsets--supporting legacy GPON, current 10Gbps XG(S)PON, and future 25G/50G applications--we design advanced APD/PIN TIAs, laser drivers, receivers, and integrated transceivers powering global fibre-to-the-home (FTTH) infrastructure. You'll work alongside talented RF IC designers and engineers, collaborating across multiple disciplines to shape the future of high-speed connectivity.
Job Summary:
This is a hands-on, technically demanding role for an experienced engineer with a passion for precision testing, signal integrity, and cross-functional collaboration. As a Senior Staff Characterisation Engineer, you'll be responsible for the bring-up, automation, and execution of test systems for high-speed mixed-signal ICs. Using state-of-the-art bench equipment (DCA, BERT, LCA, etc.) and Python-based automation, you'll measure, analyse, and report product performance across PVT conditions, supporting successful new product introductions from early development through to release.
If you thrive in a fast-paced R&D environment, love solving technical challenges, and want to work on products used in millions of homes worldwide, this is your opportunity.
Responsibilities:Collaborate closely across functions--design, validation, test, product, and applications--throughout the full NPI lifecycle. Develop and execute detailed characterisation test plans for new mixed-signal/optical ICs. Specify and configure lab-based test equipment for high-speed optical/electrical characterisation. Design and implement test setups including PCBs, fixturing, and integration of test instruments. Develop Python-based automation software to streamline characterisation workflows. Perform hands-on lab testing using BERTs, DCAs, VNAs, and other high-frequency equipment. Analyse data and produce high-quality reports, presenting findings in formal design and review meetings. Troubleshoot unexpected results, identify root causes, and work proactively to de-bug and resolve issues. Prioritise and manage tasks effectively, ensuring delivery of characterisation results to schedule. Build and maintain strong cross-functional relationships to drive progress and ensure product success.

Minimum Qualifications:BSc/MSc in Electrical/Electronic Engineering, or HNC/HND with equivalent industry experience. Proven ability to work under pressure in a fast-paced, dynamic R&D environment. Strong teamwork and communication skills--collaborative, reliable, and transparent. Excellent analytical thinking and attention to detail. Able to self-learn and independently acquire technical knowledge. Passion for problem-solving and creative innovation.

Desired Qualifications:5+ years of experience in the semiconductor or optical communications industry. Strong fundamentals in signal integrity and high-speed lab testing. Proficient in Python scripting for test automation. Experience with test instrumentation such as BERTs, DCAs, VNAs, and LCAs.

Career Growth Philosophy:

At Semtech, we believe that innovation starts with people. That's why we're committed to empowering your professional development--through access to mentorship, learning resources, and a collaborative, idea-rich environment. Our pay-for-performance culture rewards initiative, encourages growth, and celebrates meaningful contributions.
