Company

hirify.global develops chips and systems designed to accelerate inference for frontier AI models, including rack-scale hardware and control software.

What you will do

• Develop firmware and services for rack management, BMC, and board/device controllers across bare metal, RTOS, and embedded Linux.
• Build board and rack management systems from hardware bring-up through production deployment.
• Implement power-on, provisioning, monitoring, telemetry, updates, recovery, and security flows that keep device fleets healthy.
• Integrate with host and device stacks, including drivers and runtime libraries, to provide end-to-end operation.
• Work with hardware and device software teams to define interfaces, validate behaviour, and debug boundary issues.

Requirements

• Proven experience shipping production-critical, reliable embedded systems across at least two of bare metal, RTOS, and embedded Linux, or deep expertise in one with the ability to ramp up on the others.
• Strong C and/or Rust skills, with sound engineering judgement around safety, testing, debugging, and failure modes.
• Reliability-first approach focused on observability, diagnosability, predictable recovery paths, and testability.
• Experience working close to the hardware/software boundary, including bootloaders, BSP, or kernel-adjacent work, and collaborating with hardware, driver, and runtime teams.
• Collaborative, high-ownership working style with clear communication and willingness to solve difficult problems with others.
• Degree in Computer Science, Electronic Engineering, Maths, Physics, or a related subject, plus 3+ years of industry experience.

Nice to have

• Embedded platform or systems firmware experience, including board management, BMC-style stacks, or rack controllers.
• OpenBMC or embedded Linux image build and customisation experience.
• Zephyr or similar RTOS experience.
• Practical security experience or instincts around secure boot, signed updates, device identity, fail-safe design, and clean recovery.
• Kernel device work involving drivers, device tree, bring-up, performance, or tracing.
• Hardware bring-up experience with logic analysers, oscilloscopes, or waveform viewers.
• RISC-V familiarity and experience with GPUs or ML accelerators.

Culture & Benefits

• Full-time role in London or Bristol.
• Private medical, dental, and vision coverage.
• Contributory pension, 25 days of holiday plus bank holidays, and life/critical illness insurance.
• Meaningful equity and ownership participation.
