About Appvia
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.
About The Role
We're hiring multiple Senior Full Stack Engineers (Java / TypeScript) to join a growing Software Engineering practice supporting a major modernisation and AI-enabled transformation programme.
This is a hands-on, client-facing role where you'll help design and deliver modern software solutions in complex environments. You'll be working on what is effectively a greenfield build within a brownfield ecosystem, introducing new architecture, tooling, and engineering standards to enable long-term scalability and resilience.
You will report into a Principal Software Engineer, contributing both to day-to-day delivery and the continued growth of Appvia's software engineering capability and technical direction.

Requirements
About You
You are a strong full-stack engineer with a consulting mindset, comfortable working in complex environments and influencing how software is designed and delivered.
You will bring:
- Strong experience with TypeScript and modern Frontend development
- Strong backend experience with Java (Spring Boot)
- A solid grounding in Domain Driven Design (DDD)
- Experience working with microservices architectures
- Full-stack capability across UI, API, and data layers
- Experience working in cloud-native environments (ideally AWS)
- Interest or experience in AI-assisted development to improve productivity and quality
- Confidence working directly with stakeholders and guiding technical decisions
