Functional Test Engineers

We are looking for experienced Functional Test Engineers with hands‑on software testing experience to join our product development teams.

You will work inside a software scrum team, performing functional testing on complex embedded communication systems (TETRA/LTE devices), ensuring features meet expected behaviour, reliability, and customer expectations.

This role requires a strong technical tester who can analyse requirements, design effective test cases, uncover edge cases, perform detailed investigations, and contribute to maintaining product quality throughout the sprint.

You will also contribute to automation of high‑value checks to support sprint efficiency and reduce regression cycles.

This role is primarily on‑site in our Waterbeach office. With all teams across electronics, hardware, mechanical and software design, development and testing under one roof, Sepura thrives through its collaborative environment, with a workspace that supports rapid learning and innovation.

Our customer base includes many different industries and markets around the world. Our complete TETRA and LTE solutions have been developed specifically for users in multiple sectors to face their critical communications challenges.

The activities you will be responsible for include:

• Work as part of a software scrum team, responsible for verifying new features and changes during the sprint.
• Reading and understanding requirements documentation provided by a Product Definition Team, Product Strategy Team.
• Review user stories, acceptance criteria, and specifications to ensure clarity and testability.
• Involvement in test planning, test execution, defect tracking, and reporting to stakeholders.
• Design clear, thorough, and traceable functional test cases, and execute them across embedded devices, software components, and APIs.
• Developing and executing automated test cases for Sepura’s LTE and TETRA products.
• Perform exploratory testing to uncover unexpected behaviours, usability issues, and edge cases.
• Validate fixes and confirm regression risk areas following developer changes.
• Analyse logs, system traces, and debug output to support accurate defect reporting.
• Participate in sprint activities: planning, backlog refinement, daily stand‑ups, sprint reviews, and retrospectives.
• Collaborate closely with developers to investigate issues, interpret logs, and reproduce complex defects.
• Work with Product Owners to ensure acceptance criteria are testable and complete.
• Provide clear, concise updates on test progress, risks, blockers, and readiness.
