Accenture is partnering with scaled UK AI compute pioneers to lead the charge on next‑generation infrastructure for sovereign AI. We are building a high‑performance compute operations team in London. Our work is sensitive, secure, 24x7, and on the most up‑to‑date high‑density compute stacks available.

Any offer of employment is subject to satisfactory BPSS and SC security clearance, which requires 5 years of continuous UK address history (typically including no periods of 30 consecutive days or more spent outside of the UK) at the point of application.
