Senior Full Stack Developer - UK Security Clearance Eligibility required.

Appvia is a specialist cloud, platform, and solutions engineering consultancy, helping organisations modernise software systems, improve developer productivity, and adopt cloud-native practices that enable long-term, sustainable delivery.

Our software engineering capability focuses on modern application development, domain-driven design, and improving delivery outcomes through better architecture, testing, and developer experience.

We work across complex, high-impact environments in both the public and private sector, delivering solutions where quality, scalability, and reliability are critical.

We are hiring multiple Senior Java / React Full Stack Developers to join a growing Software Engineering practice, supporting a large-scale modernisation and AI-enabled transformation programme.

This is a hands-on, client-facing role where you will help shape and deliver modern software solutions within complex environments working on what is effectively a greenfield build within a brownfield ecosystem, introducing new architecture, tooling, and engineering standards to enable long-term scalability.

You will report into a Principal Software Engineer, contributing to both delivery and the continued growth of Appvia’s software engineering capability.
