Job Description

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.

The Role

We're searching for a Director of Hardware - ASICs to own the technical, schedule and organisational delivery of multiple ASICs within OTPU. You will line?manage the Analog ASIC Lead and Digital ASIC Lead (each with their own teams) and act as the single point of accountability for silicon execution. Success demands a rare blend of hands?on technical depth, proven people leadership and disciplined program management--all exercised across multiple concurrent tape?outs.

Responsibilities

Build and maintain the ASIC master schedule--including IP development, verification, physical implementation, package co?design, MPW/test?chip shuttles, qualification and production ramps. Drive weekly cross?functional reviews and executive read?outs. Directly manage and mentor the Analog and Digital ASIC Leads (and, via them, ~25 + engineers). Set goals, hire strategically, grow technical leaders and foster a culture of first?pass silicon success. Provide architectural guidance and critical design?review sign?off for blocks running from

> 20 GHz analog bandwidth

to

> 100 MHz digital core clocks

. Resolve spec splits, timing closures, power budgets and mixed?signal interactions. Act as primary interface to foundry and IP vendors: negotiate PDK access, mask slots, MPW shuttles, wafer starts, corner?split strategies and yield?learning plans. Own silicon CAPEX/OPEX budgets, mask and backend costs, and risk registers. Drive make/buy decisions for IP, EDA, test hardware and probe cards.
