The Satcom team is responsible for the design, delivery and performance of Open Cosmos’ satellite communications services, spanning the space segment, ground infrastructure and integral connectivity.

The team are currently looking for an Embedded Systems Engineer, who’ll design and develop the real-time embedded software and firmware that powers critical hardware across both ground and space systems.

What will you be doing?

Develop embedded software and firmware for real-time control and telemetry systems

Design FPGA and firmware solutions using VHDL/Verilog for high-speed hardware control

Build and optimise embedded C/C++ applications within RTOS environments

Implement deterministic control loops and low-level hardware interfaces

Develop robust communication protocols across digital and RF subsystems





Design fault-tolerant and resilient system architectures for high-reliability environments

Support hardware-in-the-loop testing, integration, debugging, and verification activities

Optimise performance, power consumption, and memory usage in constrained embedded systems

Contribute to secure remote management and monitoring capabilities for deployed systems

Work closely with systems, hardware, RF, and software teams to deliver integrated solutions

What You’ll bring

Strong knowledge of embedded systems operating within real-time or constrained environments

Proficiency in embedded C/C++ and RTOS-based development

Strong capability in FPGA and firmware development using VHDL, Verilog, or similar HDL technologies

Solid understanding of low-level communication interfaces such as SPI, I2C, UART, CAN, or Ethernet

Capability in debugging and verification using tools such as JTAG, logic analysers, or HIL environments
