Embedded System Engineer in Harwell

At Open Cosmos we are solving the world’s biggest challenges from space, providing businesses, governments and researchers access to more readily available information than ever before. The Satcom team is responsible for the design, delivery and performance of Open Cosmos’ satellite communications services, spanning the space segment, ground infrastructure and global 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
• Strong understanding of fault‑tolerant and resilient embedded system design principles
• Knowledge of high‑speed interfaces and integration between FPGA, DSP, and RF systems
• A methodical approach to problem‑solving with strong attention to detail
• Strong collaboration and communication skills across multidisciplinary engineering teams
• Awareness of high‑reliability engineering practices within aerospace, defence, or similarly demanding environments

This role will be based in any of our locations.

Why Open Cosmos?

• Work at the cutting edge of space technology with customers around the globe
• A mission‑driven company making space accessible to help solve real‑world challenges
• A diverse, ambitious, and supportive team
