About the role
Mubit is hiring its first Backend/Infrastructure Engineer in London to build the 'operational memory' for AI agents. Currently, agents are like goldfish—they forget context, causing engineers to spend hours on manual fixes. You'll architect high performance systems from scratch to give agents sub 80ms recall and shared state. If you have 4 8 years of experience in distributed systems and want to own the plumbing for the next generation of AI, join this well funded founding team in Canary Wharf.
