Connecting top Embedded & C++ talent to companies in NRW 🌍

What You Will Be Responsible For

• Design and development of complex embedded software architectures for microcontroller- and SoC-based systems
• Implementation of real-time firmware components in C / C++, including scheduling concepts, state machines, and safety mechanisms
• Development of low-level drivers and hardware abstraction layers with deterministic behaviour
• Analysis and optimisation of timing, latency, memory usage, and CPU load
• Definition and enforcement of software architecture guidelines and coding standards
• Integration of firmware with complex hardware designs, including fault handling and diagnostics
• Support of hardware bring-up, root-cause analysis, and system debugging at register and signal level
• Collaboration with electronics, system, and test engineers across the full product lifecycle
• Contribution to technical design reviews, architecture discussions, and long-term platform strategy
• Mentoring of less experienced embedded developers and knowledge sharing within the team

Your Technical Background

• Degree in Electrical Engineering, Computer Engineering, Embedded Systems, or comparable qualification
• Several years of professional experience in embedded software development on complex systems
• Very strong skills in C / C++ for resource-constrained, real-time environments
• Deep understanding of:
• Real-time system design and scheduling
• Interrupt handling, DMA, timers, watchdogs
• Memory management, stack/heap analysis
• Deterministic behaviour and fault tolerance
• Extensive experience with ARM Cortex-M or Cortex-A architectures
• Solid knowledge of RTOS internals (e.g. task scheduling, priority inversion, synchronisation mechanisms)
• Experience analysing system behaviour using oscilloscopes, logic analysers, trace tools, and debuggers
• Ability to read schematics and reason about hardware/software interaction
• Familiarity with structured development processes, testing strategies, and long-term maintainability

Technology & System Environment

• ARM-based microcontrollers and SoCs
• Bare-metal and RTOS-based firmware
• C / C++ (modern, performance-oriented usage)
• Complex peripheral interaction (ADC, PWM, high-speed communication interfaces)
