19 companies checked against their own careers boards. Five are hiring in the UK right now at a pace worth a call this week. All five post hard infrastructure roles that agencies fill. London is the hub. Liverpool, Newport, Glasgow, Crawley and Gloucestershire are the UK data centre sites with live or coming roles. Counts are postings, not seats.
Nebius, construction recruitment. Warm. Lead with the roles live on their board: Construction Project Manager, Project Development Manager, Site Selection Manager, Technical Due Diligence Manager, Chief Power Engineer. Then the UK sites: Newport and three more to 65MW by 2027.
Nscale, Radiant, Nebius, CoreWeave EU, Verda. Each has a live board, a UK site and a reason to talk this month. Go in with one hard role each, not a credentials deck.
NexGen Cloud, Crusoe, Cudo, Mistral, Sesterce, Fluidstack. Smaller boards or EU first. Cudo has no public board: go direct to the CEO or COO.
Eight names to recheck monthly. Northern Data after the Rumble deal is a candidate source, not a client.
Every neocloud role in the USA, EU and UK, who posted, who pulled. Free. It is the reason a hiring manager takes the first call and the reason they take the second.
Kao Data, DataVita, Digital Realty, Global Switch, Vantage. They hire technicians and shift managers too, and they know every neocloud build in the UK before it is announced.

Plus a second wave in London that agencies win on speed: finance (Nscale, Radiant, Nebius and NexGen all post accountants and FP&A now) and product managers (Radiant has 13 open). And the construction wave ahead of all of it: site selection, development, construction project management, commissioning. That is where Nebius is hiring and where we start.
