Senior Modem Verification Engineer

Mars; Oxford; Hybrid; GBP 70,000 - 110,000; Full time

Job summary

MARS Recruitment is seeking a Senior Modem Verification Engineer for a Next-Gen Wireless Communications start-up in Oxford. The role is hybrid—1 day on site per week—and involves collaborating across modem software, FPGA, protocol stacks and embedded teams to define verification strategy and build repeatable test infrastructure.

You will analyse results, investigate failures with engineering leads and ensure product performance is supported by objective evidence.

Qualifications

• Strong experience in verification, test or systems engineering for communications, DSP, embedded, FPGA-based or similarly complex real-time products.
• Experience designing automated verification and regression frameworks rather than only executing manually defined test procedures.
• Strong understanding of digital communications or signal processing systems to interpret modem performance data.
• Practical experience with Python, C/C++ and/or MATLAB for test automation and data analysis.
• Experience with CI/CD, version control and disciplined software release practices.

Responsibilities

• Define verification strategy and build repeatable test infrastructure for modem components and systems.
• Analyse results, investigate failures with engineering leads, and drive root-cause investigations.
• Provide objective evidence to support product performance and release decisions.

Job description

Senior Modem Verification Engineer Next-Gen Wireless Comms Start-up Oxford / Hybrid 1 day per week onsite, The Senior Modem Verification Engineer will work across modem software, FPGA, protocol-stack, embedded and platform-integration teams to define how components and complete systems are verified. They will build repeatable test infrastructure, analyse results, investigate failures with engineering leads, and ensure that product performance and release decisions are supported by objective evidence.

• Strong professional experience in verification, test or systems engineering for communications, DSP, embedded, FPGA-based or similarly complex real-time products.
• Experience designing automated verification and regression frameworks rather than only executing manually defined test procedures.
• Strong understanding of digital communications or signal processing systems, sufficient to interpret modem performance data and work effectively with PHY/DSP engineers.
• Practical experience validating numerical or signal processing implementations against reference models, expected outputs or golden vector datasets.
• Experience with Python, C/C++ and/or MATLAB or equivalent tools for test automation, data analysis and engineering investigation.
• Experience with CI/CD or continuous integration environments, automated test execution, version control and disciplined software release practices.
• Strong analytical ability, including interpreting large test datasets, identifying regressions, reproducing failures and helping multidisciplinary teams isolate root causes.
• Experience defining test plans, acceptance criteria and objective pass/fail measures for complex engineering systems.
• Ability to work across software, FPGA, embedded, RF and systems disciplines without taking ownership away from the engineers responsible for those components.
• Strong written communication and documentation skills, including clear test specifications, results, defect evidence and verification reports.
• Comfort operating as a hands-on senior engineer in a small, fast-moving multidisciplinary team.
• UK-based, able to work effectively with UK defence customers, and eligible for appropriate security vetting where required.
