Five open positions across Britain's hard tech sector this week — two software, two hardware, one ops.
Software Engineering & AI
Compiler Engineer — Olix
Build the ML compiler, runtime, and debugger for Olix's photonic Optical Tensor Processing Unit (OTPU) — connecting major frameworks to a novel AI accelerator that uses light rather than electricity. Olix is valued above $1 billion with product shipments targeted for 2027.
- Location: London (On-site)
- Salary: £174,000–£234,000
- Visa sponsorship: Available
Senior Linux Kernel Driver Engineer — Fractile
Write kernel drivers for Fractile's custom AI inference accelerator — PCIe device management, DMA, memory handling, and interrupt paths. Fractile's in-memory computing approach claims to enable LLMs up to 100x faster than GPUs.
- Location: London (Hybrid)
Hardware Engineering
Senior Hardware Engineer — Fractile
Design high-speed digital and high-power electronic systems for Fractile's chip, from schematics through to manufacturing release. The architecture fuses computation with memory, eliminating the data-movement bottleneck that limits conventional GPUs.
- Location: Bristol
Senior PCB Layout Engineer — Fractile
Own the full lifecycle of complex, multi-layer PCB layouts — library governance, signal integrity routing, and design for manufacture. Experience with 10+ layer boards and high-speed interfaces required.
- Location: Bristol
Commercial & Operations
Deployment Operations Lead, International — Anduril
Lead international deployment operations for Anduril's autonomous defence systems — maritime surveillance towers, drones, and more. Anduril operates on a Silicon Valley model to deliver defence hardware in months, not years.
