G3 Systems Ltd Tech Stack

Defence and government infrastructure: design, deployment, and field operations

Engineering Services Portland, Dorset 501–1,000 employees Founded 2001 Privately Held

G3 Systems designs and deploys resilient infrastructure for defence and government clients, with a core focus on modular, containerised systems that operate in remote and austere environments. The stack is heavy on project management (Primavera P6, Microsoft Project) and design automation (AutoCAD, Inventor, Trimble MEP), reflecting the complexity of coordinating large-scale deployments. Active hiring is concentrated in engineering roles, and internal pain points centre on managing attrition within that function and ensuring operational readiness of deployed systems — suggesting the company is scaling delivery capacity while facing retention pressure in its technical core.
