Flux Computing designs and manufactures optical processors to train and run inference on large AI models. Join us in London to be part of a highly motivated and skilled team that thrives on delivering impact and innovation at speed.
We are seeking a Physical Layout Engineer to own the full‑custom layout of ultra‑high‑speed analog blocks that lie at the heart of the OTPU including: high speed DAC/ADC/TIAS, sub‑100 fs‑rms jitter PLLs and large multi-lane clock‑distribution meshes.
- Plan, execute and sign‑off full‑custom layouts for high‑speed analog/RF IP (TIAs, PLLs, CDRs, drivers, samplers, bias networks, ESD clamps).
- Perform parasitic extraction and EM/IR, thermal and electro‑migration analysis (Cadence Quantus / Calibre xRC, Voltus, EMX / HFSS), iterate with circuit designers to close speed, noise and phase‑noise margins.
- Ensure all blocks pass sign‑off: DRC, LVS, ERC, ESD, latch‑up, DFM and foundry‑specific reliability checks.
- Collaborate with packaging and signal‑integrity teams to co‑design interposer, substrate and PCB break‑outs.
- Create and maintain layout guidelines, checklists and Skill/Tcl/Python automation scripts.
- 10 GHz analog front‑ends or 56 ‑ 112 Gb/s SerDes / CDR / PLL blocks.
- ~ 5D/3D IC or chiplet integration and the associated inductance / crosstalk challenges.
- ~ Proficient in Skill, Tcl or Python to automate repetitive layout and sign‑off tasks.
- ~ Comfortable working across circuit design, packaging, signal‑integrity and manufacturing teams in a fast‑moving environment.
Compensation & Benefits:
- Competitive salary and stock options in a rapidly growing AI company.
- Based in our new 5,000 sq. ft. office in the AI hub of Kings Cross, London.
- Comprehensive healthcare insurance.
