Functional Test Engineers

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

As a member of a software scrum team, you will perform functional testing on complex embedded communication systems (TETRA/LTE devices), ensuring features meet expected behavior, reliability, and customer expectations.

Responsibilities

• Verify new features and changes during the sprint.
• Read and understand requirements documentation from the Product Definition and Product Strategy teams.
• Review user stories, acceptance criteria, and specifications to ensure clarity and testability.
• Participate 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.
• Develop and execute 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.
• 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.
• Participate in sprint activities: planning, backlog refinement, daily stand ups, sprint reviews, and retrospectives.

Qualifications & Certifications

• Bachelor's or Master's degree in Computer Science, Electronics, Telecommunications, or a related field.

• Proficiency designing functional test cases using structured techniques (equivalence, boundary, state based, risk based).
• Responsibility for the development, maintenance, and full ownership of the team's Test Strategy.
• Expertise in exploratory testing and identification of edge cases.
• Confidence in analysing logs, debugging issues, and collaborating directly with developers.
• Strong defect reporting skills with clear reproduction steps, evidence, and impact details.
• Knowledge of test automation tools (Selenium, Robot Framework, Appium, etc.) and experience writing automated test scripts in Python or C# for sprint level testing.
• Familiarity with test management and issue tracking tools (Jira, Jama, Azure DevOps, etc.).
• Experience with embedded Linux or radio firmware log analysis.
• Knowledge of protocol testing, RF testing, and communication interfaces (TCP/IP, UDP, Serial, Bluetooth, etc.) is a plus.
• Experience using Git, Bitbucket, or similar version control systems.
• Demonstrated ownership and accountability for product quality.

Nice to have Experience

• Experience testing telecom protocols, embedded software, or RF based devices.
• Exposure to CI/CD pipelines (GitHub Actions, Jenkins, GitLab CI, DevOps).
• Familiarity with Git branching strategies and code reviews for automated tests.
• Experience with performance, soak, or reliability testing.

Personal Attributes

• Strong attention to detail and methodical approach.
• Excellent communication skills with both technical and non technical stakeholders.
