Join the Growth Story at Envitia. Envitia operates at the heart of the UK’s most sensitive and high-profile operations. Our approach is entirely mission-focused, enabling customers to see more, decide faster, and act with confidence across complex domains.

The Role

As a UX Front-End Developer at Envitia, you will design, prototype, and build intuitive, accessible, and high-performing user interfaces that support secure government applications. Working within our Consulting division, you will contribute directly to enhancing mission-critical digital services used across our Security & Intelligence customer base. In this role, you’ll bring together strong UX and UI expertise with practical front-end development skills to translate complex user needs into elegant, reliable solutions. You’ll work collaboratively with product owners, user researchers, backend engineers, and security architects to ensure that usability, accessibility, and performance requirements are met throughout the development lifecycle.

This position is well suited to someone who thrives in technically challenging environments, enjoys solving real user problems, and is confident operating within highly secure, multidisciplinary project teams. You’ll have the opportunity to shape the user experience of impactful national-level systems while advancing Envitia’s reputation for delivering high-quality, user-centred digital solutions.

Collaborate closely with UX researchers, developers, testers and security/solution architects to ensure seamless, end-to-end delivery. Produce clear documentation, interface specifications and design artefacts to support delivery and ongoing maintenance.
• Quality, Standards & Governance: Ensure all interfaces meet required accessibility standards (e.g., WCAG 2.1 AA or client-specific mandates). Apply secure coding and design principles when working within classified or sensitive environments. Adhere to Envitia’s engineering, design and DevSecOps standards, contributing improvements where appropriate.
