Zaizi builds and runs secure digital services for UK government, with a growing defence tilt: projects include MOD mission-critical web apps, TAK tactical edge integrations and sovereign landing zones. The stack pairs AWS, Kubernetes and GitLab CI with on-device AI tooling (ExecuTorch, ONNX Runtime, TensorFlow Lite, Llama 3), pointing to edge-native model deployment. Hiring is senior, engineering-heavy and slowing.
