The Role

As an Enterprise Architect at Envitia, you will play a pivotal role in helping Central Government and Defence organisations tackle complex challenges and realise their strategic ambitions. Acting as a trusted advisor to senior stakeholders, you will shape enterprise-wide business and technology architectures that enable sustainable transformation and long-term success.

Combining strategic insight with a strong consulting mindset, you will define future-state visions, operating models, roadmaps, and target architectures that align technology investment to measurable business outcomes. You will work closely with clients to ensure architectural decisions are driven by organisational priorities and deliver genuine value.

Beyond architecture design, you will lead the adoption of new capabilities and ways of working, guiding stakeholders through change and ensuring solutions are successfully embedded. From early-stage strategy and advisory engagements through to delivery and transition, you will provide leadership, direction, and expertise across the entire client lifecycle.

This is an opportunity to influence critical programmes at the heart of Government and Defence, while helping to grow Envitia's consulting capability and reputation as a trusted transformation partner.
