Cogna, a London company founded in 2023, builds production AI applications for physical-industry operators. Its stack pairs RAG, FastAPI and GPT-3.5 with Temporal, Dagster, gRPC, Bazel and Kubernetes on Azure, alongside Rust, Haskell and OCaml, which points to a platform-grade engineering culture rather than a services shop. Hiring is accelerating and engineering-heavy, aimed at LLM evaluation, internal tooling frameworks and workflow orchestration.
Cogna develops custom AI and ML software for physical industries, the sectors that power, move, build and maintain critical infrastructure. Its applications target manual, knowledge-intensive work where operating context sits across documents, systems and experienced staff. The company was founded in 2023, is privately held, is headquartered in London, and has 51–200 employees. It hires in the United Kingdom across engineering, product and sales, and works directly with customers to build working systems.
Cogna uses Python, TypeScript, Rust, Go, Haskell, OCaml, C++, Java and C#, with FastAPI, gRPC, Temporal, Dagster, Bazel, Kubernetes and Terraform on Azure. Datadog handles monitoring, and its AI work relies on RAG and GPT-3.5.
Yes. Cogna's hiring is accelerating and mostly in engineering at mid level, with smaller product and sales needs. All of its hiring is in the United Kingdom.
Cogna is building AI-first product features, LLM evaluation systems and benchmarks, internal LLM tooling frameworks, and cloud platform infrastructure. It is also improving workflow orchestration and its build and delivery systems.
