The Role

As a Principal Solution Architect, you will lead the design and delivery of complex digital and data transformation solutions for Defence, Central Government and wider public sector organisations.

As part of Envitia's Consulting division, you will play a key role in growing and evolving our architecture capability. You will help develop reusable frameworks, reference architectures and best practices that accelerate delivery and strengthen our market-leading solutions.

You will work closely with customers to understand their objectives, translate complex requirements into practical and achievable solutions, and provide architectural assurance throughout the delivery lifecycle. You will also support business growth through pre-sales activities, leading solution development, shaping technical approaches, producing cost and effort estimates, and contributing to compelling client proposals.

Beyond project delivery, you will represent Envitia within the wider market, attending industry events, engaging with customer communities, and showcasing our expertise, products and innovation across data, geospatial and digital transformation domains.
