Software Version Control

Translate customer and system requirements into software definitions, specifications and acceptance criteria.
Design software architecture and interfaces for embedded controllers: STM32, FreeRTOS
Develop, test and integrate control firmware/applications in embedded C/C++ to MIRSA-C:2012, IEC61508 and CERT-C standards.
Implement communication protocols (e.g., Modbus/TCP, serial comms (RS232/422/485), Ethernet) and integrate with analogue sensors/actuators using ADCs/DACs.
Create unit testing, static analysis, code coverage, HIL/SIL test benches and perform code peer-reviews to ensure quality and safety.
Generate design documentation (specifications, diagrams, test plans, release notes)
Develop in a trunk-based-development fashion following Semantic Versioning control utilizing Git for source control.
Support manufacturing, commissioning, testing and service teams in diagnosing and resolving issues.
Contribute to continuous improvement of software development processes, standards, and tooling.

Degree in Software, Computer, Electrical/Control Engineering or equivalent experience.
Professional experience developing embedded or industrial control software.
Proficiency in one or more: C/C++ targeting ARM Cortex-M microcontrollers (STM32 preferred) Strong working knowledge of FreeRTOS or equivalent RTOS - task scheduling, inter-task communication, priority management, and real-time debugging.
Familiarity with MIRSA-C:2012, IEC 61508 functional safety concepts and CERT-C secure coding practices.
Experience with unit testing frameworks (e.g. Unity/Ceedling), static analysis tooling, and code coverage measurement.
Proficiency with Git in a trunk-based development workflow using semantic versioning.
Knowledge of communication protocols (Modbus/TCP, CAN, Ethernet (UDP/TCP)) and integration with industrial sensors with safety considerations for industrial systems.
Strong problem-solving skills, collaborative mindset and clear technical communication.
Python or MATLAB experience is desirable for test tooling and automation. Ability to read electrical/mechanical drawings is a plus.
