- Work with the standards team to turn design guidance into standards profiles
- Support submissions and briefs to senior design boards,



capability gate reviews and investment committees
- Work with Defence Group and Service stakeholders on force integration design artefacts

What we’re looking for:

- Strong knowledge of the OSI model from the transport layer down to the physical layer, including WAN standards and protocols, SATCOM and RF systems
- Experience with ICT architecture views, including the Unified Architecture Framework (UAF), and with enterprise and solution architecture
