Principle Embedded Software Engineer

Job Summary:

The Embedded Software Principal Engineer is responsible for the architecture, development, and validation of real-time embedded software for engine control systems, including ECUs/FADECs used in gas turbine engines. The role focuses on delivering reliable, safety-critical firmware compliant with aerospace and defence standards, with close integration to the electrical hardware, performance models, and safety systems. This is a senior technical position requiring deep embedded expertise and the ability to guide software design decisions across current and future engine platforms.

Key Responsibilities:

Software Architecture & Development

• Design and implement real-time embedded software for engine control units (ECUs), including bootloaders, task schedulers, and control logic layers.
• Develop structured code in C/C++ adhering to safety-critical standards such as DO-178C, MISRA, and ISO 26262 (where applicable).
• Interface with system-level models and control logic derived from MATLAB/Simulink and convert them into embedded code or integrate with auto-code generators.

Integration & Testing

• Integrate firmware with custom hardware (MCUs, FPGAs, power drivers, sensors, and actuators) in close coordination with hardware engineers.
• Develop and execute software-in-the-loop (SIL) and hardware-in-the-loop (HIL) tests using tools such as dSPACE, NI, or Vector.
• Lead root cause analysis and debugging using oscilloscopes, logic analyzers, and diagnostic tools.
• Ensure real-time performance and determinism under all operating conditions.

Documentation & Compliance

• Generate software requirements, design descriptions, traceability matrices, test plans, and verification artifacts in line with DO-178C and ARP4754A standards.
• Support safety assessments and participate in system-level FMEA, hazard analyses, and software reviews.
• Contribute to configuration management and version control using Git, SVN, or equivalent tools.

Collaboration & Mentorship

• Work closely with control engineers, hardware engineers, and system engineers to align software functionality with system-level goals.
• Mentor junior embedded engineers and contribute to internal software design standards and process improvement initiatives.
