We are on the lookout for a highly skilled Embedded Software Engineer to join our Traffic and Transportation division. The ideal candidate should possess a solid foundation in safety-critical real-time controls systems and have a passion for delivering innovative solutions for customers.

This role is centered around designing and developing embedded control systems for Traffic Signal Controllers, requiring expertise in safety-critical embedded software, digital hardware integration, and control systems design with a focus on compliance with SIL2 (IEC 61508) safety standards.

Main Responsibilities:

  • Design and implement safety-critical embedded software for Traffic Signal Controllers in accordance with SIL2 (IEC 61508 / ISO 26262).
  • Develop and validate conflict monitoring, phase control, and lamp monitoring algorithms for Traffic Signal Controllers.
  • Collaborate with hardware engineers in the design of fault-tolerant digital interfaces (GPIO, latching outputs, watchdogs, memory functionality, reliable flash chip programming).
  • Lead system integration across MCUs, SoCs, and RTOSs Develop and execute debug code to verify designs/ customer requirements.
  • Implement and maintain communication protocols (SCATS, NEMA TS2, ITS standards, CAN, Ethernet) for roadside devices and central system integration.
  • Develop web-based interfaces for local and remote-control functionality.
  • Ensure robust secure communications, OTA firmware updates, and diagnostics for long-term field deployments.
  • Participate in safety case documentation: hazard analysis, FMEA/FMELA, traceability, and compliance with certification bodies.
  • Mentor junior software engineers and perform peer reviews of designs and code.

Key Requirements:

  • A proven track record (10 years+) of developing embedded software for SIL2 (or higher) safety-critical systems, preferably in transportation, rail, or industrial control.
  • Strong C programming skills for MCUs and real-time operating systems, with demonstrable ability implementing algorithms and debugging hardware/ software interactions using oscilloscopes, logic analysers, and bus analysers.
  • A deep understanding of digital electronics and I/O design, including watchdogs, fail-safe states, redundancy, and EMC considerations.
  • Familiarity with protocols and standards in the traffic and transport domain (SCATS, NEMA TS2, ITS, CAN, Ethernet, Modbus, RS-485).
