Zaizi Tech Stack

Digital services and cloud transformation for UK public sector

Software Development London, England 51–200 employees Founded 2007 Privately Held

Zaizi is a 51–200-person engineering firm in London built around AWS, Kubernetes, and polyglot backend (Java, Python, Go) — a tech stack shaped for container-first cloud migration and complex system integration. The hiring mix is engineering-heavy (11 of 15 active roles, mostly senior and lead level), concentrated entirely in the UK, signaling focus on deep technical delivery rather than sales expansion. Active projects center on defence tenders, predictive maintenance systems, and legacy-to-cloud transitions, while pain-point data reveals the core challenge: untangling slow consultancy workflows and complex dependencies in high-risk, heavily regulated environments.

About Zaizi

Zaizi designs and builds digital services for UK public-sector organisations, with particular depth in defence and government cloud infrastructure. The company was founded in 2007 and operates from London as a privately held consultancy. Core work spans cloud migration (AWS, Azure, GCP), system architecture, DevOps, and emerging AI/ML applications — particularly predictive maintenance for defence use cases. The product philosophy emphasizes security and user-centric design; the operational reality focuses on managing complexity: long project lifecycles, intricate dependencies, and the regulatory and technical lift of sovereign digital programmes.
