Embedded Software Engineer; Mid-Level

Position: Embedded Software Engineer (Mid-Level)

This position requires full-time presence at our Centurion, South Africa office.

Build the firmware that powers next-generation defence technology. Alaris Antennas is looking for a mid-level Embedded Software Engineer who writes clean C, thinks in state machines, and thrives at the hardware-software boundary. If you've spent years making microcontrollers do exactly what they're supposed to—and can prove it—we want to talk.

The Role

We're seeking a talented Embedded Software Engineer to join our R&D team. This mid-level role requires solid working experience and the ability to hit the ground running. You'll design, develop, test, and debug embedded firmware that interfaces with cutting-edge antenna hardware used in defence and security applications.

Please note: This is an on-site position based in Centurion, South Africa. Remote work is not available.

What You'll Do

• Develop and optimize firmware for 8-bit, 16-bit, and 32-bit microcontrollers and embedded platforms (MIPS, ARM, STM
  32)
• Implement and manage RTOS or bare-metal solutions
• Design and maintain device drivers and middleware for communication interfaces (SPI, I²C, UART, CAN, USB, Ethernet)
• Conduct integration testing and qualification of firmware with hardware systems
• Collaborate closely with hardware engineers for seamless firmware-hardware integration
• Write technical documentation including firmware specifications, test descriptions, interface definitions, user manuals, and integration guides
• Contribute to process improvements through automation and coding standards
