Engineer 1, Embedded Software, Product Design and Engineering

We are seeking a Safety-Critical Embedded Software Test Engineer to perform independent verification of the airborne pressure sensor software. The role covers requirements-based testing automation structural coverage test-tool qualification and audit-ready evidence within a DO-178C Level A programme.

This role is fully onsite and is based at our HQ in Groby Leicestershire. This is a fixed-term role initially for one year with a likelihood of extension. Candidates must have the right to work in the UK. Due to the nature of the work additional eligibility requirements may apply. The engineer will work within the software team but collaborating closely with cross-functional teams and quality control throughout the V-lifecycle.

• Develop and maintain verification plans procedures test cases scripts reports and coverage matrices in accordance with approved project and safety plans.
• Derive normal boundary robustness failure-injection and timing tests from approved high- and low-level requirements and design.
• Maintain bidirectional traceability between requirements design tests and test results.
• Perform target-based software-software integration hardware-software integration system and regression testing.
• Support statement decision and MC/DC coverage analysis; investigate coverage gaps dead code and unintended functionality.
• Support failure investigation and root-cause analysis.
• Conduct independent formal reviews and verification activities as per the approved plans.
• Record and verify anomalies perform change-impact analysis and define regression testing strategy.
• Ensure all test artefacts tools scripts equipment configurations and results are reviewed baselined and configuration controlled.
• Develop Python-based test automation reusable libraries test data and result-processing utilities.
• Automate the test environment including the interface board pressure-control equipment power supplies and other laboratory instruments.
• Ensure traceability between approved test cases automated scripts software builds test data and results.
• Support qualification of verification tools under DO-330/ED-215 and ensure tools are used within their approved or qualified scope.

• Experience verifying safety-critical or high-integrity embedded software on target hardware.
• Practical knowledge of DO-178C or a comparable safety lifecycle including requirements-based testing independence traceability and objective evidence.
• Python test automation and experience with embedded C/C and debugging.
• Experience producing and reviewing controlled test plans procedures cases scripts reports and traceability evidence.
• Knowledge of boundary-value analysis equivalence-partition state-transition decision-table robustness and fault-injection testing.
• Understanding of statement decision and MC/DC structural coverage.
• Experience with Git/GitHub CI workflows defect management and controlled software baselines.
• Hands-on use of oscilloscopes DMMs logic/protocol analysers programmable power supplies or automated test instruments.
• Strong technical writing analytical fault-isolation and evidence-based problem-solving skills.

• DO-330/ED-215 software tool qualification.
• Knowledge of pressure sensors avionics calibration compensation algorithms or pressure-control systems.
• Robot Framework and structural-coverage tools such as Parasoft C/Ctest LDRA or Cantata.
• Worst-case execution-time analysis using Rapita/RapiTime or a comparable tool.
• SPI I2C UART/RS232 and CAN.
• Experience working with IBM DOORS.
• MISRA C/C static analysis hardware-in-the-loop testing and deterministic test-rig control.
• CI/CD pipeline configuration or integration using GitHub Actions.
