The Opportunities

We are hiring experienced Firmware Engineers for two separate positions within a specialist storage-controller development team working on NAND, PCIe and NVMe technologies. This is part of a full team build project for a global semiconductor customer.

• Role 1: Flash Layer Firmware Engineer focused on raw NAND interfaces, flash bring-up, characterisation and hardware abstraction.
• Role 2: PCIe/NVMe Firmware Engineer focused on storage-controller firmware, PCIe/NVMe protocols, low-level drivers and performance optimisation.

Both roles are hands-on and involve close collaboration with hardware and validation teams.

Role 1 – Flash Layer Firmware EngineerOwn the raw NAND interface and device abstraction layer at the foundation of the controller firmware stack, covering NAND protocols, device bring-up, characterisation and calibration.

• Key ResponsibilitiesDevelop NAND firmware supporting ONFI 4.x/5.x and Toggle Mode
• Implement command sets, timing calibration and multi-die/multi-plane operation
• Lead bring-up and qualification of new NAND vendors and generations
• Characterise retention, disturb, Vth shifts, inter-cell interference and P/E-cycle effects
• Debug flash issues using logic analysers and protocol analysers
• Support FPGA prototyping and EVT/DVT/PVT validation

• Ideal BackgroundStrong embedded C firmware experience
• Deep knowledge of NAND architecture and flash technology
• Understanding of NAND reliability mechanisms
• Python experience for automation and data analysis
• Experience with multiple NAND vendors is highly desirable

Role 2 – PCIe/NVMe Firmware EngineerOwn firmware modules for PCIe/NVMe storage controllers, working across low-level drivers, hardware abstraction, performance optimisation and standards compliance.

• Key ResponsibilitiesDevelop and maintain PCIe/NVMe controller firmware
• Design and own low-level drivers, HALs and performance-critical subsystems
• Debug hardware/firmware issues using JTAG, logic analysers and protocol analysers
• Support hardware bring-up, FPGA platforms and EVT/DVT prototypes
• Ensure compliance with NVMe, PCIe and related standards
