Our technology supports mission critical workflows across government, healthcare, and enterprise, including:\nScaling open-weight models without external inference endpoints.\n\nPutting frontier class AI to work across organisations through partnerships with other leading AI startups such as Perplexity.\n\nIncreasing operational resiliency for air gapped, on prem, and cloud based systems.\n\nSecuring intellectual property and maintaining auditability for high stakes enterprise environments.\n\nFacilitating secure information flow during disaster response, M&A due diligence, and privileged legal communications.\n\nWe’ve only scratched the surface. Built in Britain by veterans of the Ministry of Defence, British Forces, Darktrace, and elite engineering backgrounds, we are driven by a shared mission to safeguard western democracy . Whether you join our London HQ or our wider global organisation, you’ll be part of a collaborative, high performing team creating the cutting edge software and infrastructure that defines the frontier of enterprise AI.\nThe Role\nYou will make the data services and processing workloads supporting ACRA and Valarie reproducible to deploy, observable in production and safe to recover.
