Job description

Overview

Sepura is seeking Electronics Test Automation Engineers to strengthen our electronics verification capability by automating manual hardware tests and improving test efficiency, repeatability, and coverage. This role is automation-led. While exposure to RF, baseband, or radio technologies is beneficial, deep RF expertise is not required and will be developed on the job. The successful candidate will focus on converting existing manual electronics tests into robust, maintainable automated solutions and supporting manual execution where automation is not yet available. You will work closely with electronics, RF, and baseband engineers to support development, characterisation, and verification of new hardware platforms across multiple radio technologies. This is an exciting time of growth at Sepura Ltd, based in Waterbeach, Cambridge.

Role

As part of the Electronics Verification team, you will:

• Execute manual electronics tests on development and prototype hardware.
• Design, develop, and maintain test automation to replace manual procedures.
• Translate manual test cases into repeatable, automated workflows.
• Develop Python-based test scripts and frameworks to:
• Control DUTs and lab equipment
• Capture and validate measurement data
• Post-process results and generate reports
• Improve test execution time, reliability, and coverage through automation.
• Log defects, test results, and automation progress in Jira.
• Support debugging and root-cause analysis of test failures in collaboration with design teams.
• Contribute to the evolution of Sepura’s electronics Automation capability.

Day-to-Day Activities

• Running manual electronics tests on early hardware revisions.
• Automating existing manual test campaigns.
• Developing and maintaining Python test libraries and utilities.
• Interfacing with lab instruments (via SCPI, VISA, serial, USB, Ethernet, etc.).
• Analyzing test results and identifying anomalies.
• Supporting characterisation and verification activities across components, subsystems, and integrated systems.
• Collaborating with RF, baseband, conformance, and production test teams to ensure alignment of test methods.
• Gradually building domain knowledge in RF and radio technologies (training provided).

What You Need to Succeed

Experience and Skills (Essential):

• Strong Python programming skills.
• Proven experience in test automation (hardware, system, or integration level).
• Experience controlling test equipment or external devices via software.
• Good software engineering practices:
  • Git / version control
  • Modular and maintainable code
  • Logging and debugging
  • Ability to understand manual test procedures and systematically automate them.
• Comfortable working in a lab environment with physical hardware.

Desirable:

• Exposure to electronics, embedded systems, or hardware testing.
• Experience with:
  • LTE, TETRA, Wi-Fi, Bluetooth, GNSS
  • RF testing
  • Robot Framework or similar test frameworks
  • CI/CD integration for hardware or system tests
  • Basic understanding of measurement equipment (spectrum analysers, signal generators, oscilloscopes, power supplies)
• Exposure to JAMA/SpiraTests
• Excel VBA scripting
• RF and baseband expertise is not a prerequisite. Training and mentoring will be provided.

Qualifications

• HNC/HND in an appropriate subject
