Principal Solution Architect

Principal Solution Architect

Envitia is a UK-based software and services company that helps organisations unlock the full value of their data to make better, faster decisions. With over 30 years of experience, we specialise in delivering innovative software products, solutions, and consultancy services that transform complex data challenges into actionable insights.

Our mission is to empower customers across defence, government, and national security sectors to harness the power of data — from geospatial intelligence to advanced analytics and AI integration. We are proud to be a trusted partner to UK defence and government organisations, delivering technology that drives smarter, data-driven outcomes.

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. Working at the forefront of some of the UK's most critical and challenging programmes, you will shape solution strategy, define target architectures, influence senior stakeholders and provide technical leadership across multi-disciplinary teams.

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.
