Our history spans more than 50 years, and our strategy is underpinned by our core values – Integrity, Value Creation, Courage, Commitment and Compassion. These 5 core values guide every aspect of our business and are embedded in our ST Engineering culture – from the people we hire, to working with each other, to our partners and customers.

About our Business

Our Training & Simulation Systems business has close to 40 years of experience in delivering innovative learning, training, and simulation solutions to customers in the defence, public safety and security, and enterprise domains. We envision to create a better future together through learning, training, and simulation.

Together, We Can Make A Significant Impact

We are seeking a highly motivated and skilled Embedded Systems Engineer to join our dynamic engineering team. In this role, you will be responsible for the end-to-end development of firmware and low-level software for our next-generation ARM‑based embedded products running on the Linux operating system. You will play a critical part in designing, implementing, testing, and optimizing the software that brings our hardware to life.

Be Part of Our Success

• Design, develop, debug, and maintain embedded firmware and software in C/C++ for ARM‑based processors.
• Port, configure, and build custom Linux distributions (using Yocto Project or Buildroot) for new hardware platforms.
• Develop and optimize Linux kernel drivers, device trees (DTS), and board support packages (BSP) for peripherals such as I2C, SPI, UART, USB, Ethernet, and MMC/SD.
• Implement and debug system‑level software, including bootloaders (U‑Boot), kernel initialization, and power management.
• Collaborate with hardware engineers during the board bring‑up and validation phase for new PCBAs.
• Write clean, well‑documented, and maintainable code following best practices.
• Perform system‑level debugging using oscilloscopes, logic analyzers, JTAG/SWD debuggers, and kernel debugging tools.
• Create and execute unit tests, integration tests, and validation plans to ensure software quality and reliability.
• Work closely with applications software teams to define hardware‑software interfaces and system architecture.
• Participate in code and design reviews to ensure high‑quality outcomes.

Qualities We Value

• 3+ years of professional experience in embedded firmware/software development.
• Strong proficiency in C programming for constrained, resource‑embedded environments.
• Hands‑on experience with ARM Cortex‑A/M series architectures and their development ecosystems.
• Proven experience with embedded Linux: kernel configuration, driver development, and device tree.
• Solid understanding of hardware fundamentals and the ability to read electronic schematics and datasheets.
• Experience with low‑level communication protocols (e.g., I2C, SPI, UART).
• Familiarity with version control systems, preferably Git.
• Excellent problem‑solving and debugging skills.
• Experience with system build tools like the Yocto Project or Buildroot.
• Knowledge of bootloader customization, specifically U‑Boot.
• Proficiency in Python or Shell scripting for automation and testing.
• Experience with real‑time operating systems (RTOS) like FreeRTOS or Zephyr, in addition to Linux.
• Understanding of security principles in embedded systems (secure boot, trusted execution environment).
• Experience with wireless technologies (Wi‑Fi, Bluetooth, LTE).
• Knowledge of agile development methodologies.

Our Commitment That Goes Beyond the Norm

• An environment where you will be working on cutting‑edge technologies and architectures.
• Safe space where diverse perspectives are valued, and everyone’s unique contributions are celebrated.
• Meaningful work and projects that make a difference in people’s lives.
• A fun, passionate and collaborative workplace.
• Competitive remuneration and comprehensive benefits.
