As part of a unique and specialist defence company, our friendly team consists of experienced and highly capable individuals, working together with a mature ‘can do’ work ethic.

T HE ROLE
Mission Training Devices (MTD) are looking for a talented UI/UX-focused software developer to join our growing team as we expand into new and exciting projects in synthetic training and simulation.
The focus will be developing software for synthetic training devices, primarily stand-alone applications used in advanced training environments. The main focus will be mobile application development using .NET MAUI and the MVVM architecture, creating responsive, intuitive interfaces that make complex systems simple to use.
Working alongside backend developers, the successful candidate will take ownership of the user experience and interface design, shaping how users interact with our products and ensuring clean, efficient, and visually cohesive designs.
Experience with collaborative tools such as Azure DevOps, and GitHub is essential. MTD follows the SCRUM methodology, and previous Agile team experience will be advantageous.
This role is primarily home-based, with most development work carried out remotely. Occasional travel to MoD Boscombe Down is required for in-person meetings (typically once per month), with travel expenses reimbursed.
THE PERSON
We are looking for a creative and detail-oriented developer with a passion for building clean, user-focused software.
You’re comfortable balancing form and function—making interfaces that are both practical and visually elegant.
KEY RESPONSIBILITIES
* Develop and refine UIs using .NET MAUI (C# / XAML).
* Apply MVVM principles for clean, testable, and maintainable code.
* Collaborate with backend developers to integrate UI logic and data layers.
* Shape UX flow, layout, and visual structure of applications.
* Use Inkscape or similar tools to produce icons, overlays, and UI assets.
* Participate in code reviews and Agile sprints.
ESSENTIAL SKILLS

* Background in vector graphics or interface design.
Due to the nature of elements of the role, the successful applicant must be a UK National and may be required to successfully complete National Security Vetting which may require criminal record, security service and credit reference checks; qualification will also normally require a minimum UK residency of at least 5 years
