Senior Embedded Hardware Security Engineer

The Role

A Senior Embedded Hardware & Security Engineer is required to support an R&D programme focused on secure embedded hardware for Linux-based edge devices.

The project involves developing a hardware security and post-quantum cryptography demonstrator incorporating FPGA/SoC technology, hardware-derived device identity, secure key management and cryptographic acceleration.

The role will cover the development lifecycle from architecture and development boards through to prototype PCB design, hardware bring-up, software integration and hardware-in-the-loop testing.

Key Responsibilities

• Design and develop embedded electronic hardware and custom PCBs
• Component selection, schematic capture and PCB development
• Prototype hardware bring-up, debugging and testing
• Integrate FPGA/SoC platforms, TPMs, secure elements and security IP
• Develop embedded C/C++, firmware, device drivers and Linux interfaces
• Work with SPI, I²C, UART, USB, Ethernet and potentially PCIe
• Implement bootloaders, secure boot and hardware roots of trust
• Integrate cryptographic libraries, OpenSSL and PKCS#11
• Support secure key management and device authentication
• Work with post-quantum cryptography, including ML-KEM and ML-DSA
• Carry out HIL testing, security verification and threat modelling
• Produce technical documentation, schematics and test evidence

Required Experience

• Embedded hardware/electronics engineering
• Custom PCB design and hardware bring-up
• Embedded C/C++ and Linux
• ARM, RISC-V or FPGA/SoC platforms
• Hardware security and cryptography
• Secure boot, TPMs, secure elements or hardware roots of trust
• SPI, I²C, UART, USB and Ethernet
• Hardware debugging using oscilloscopes, logic analysers and JTAG

FPGA integration experience is desirable, but deep RTL development is not essential. A traditional cybersecurity background is not required where there is strong embedded/electronics experience combined with relevant cryptographic knowledge.
