Junior / Mid-Level Full Stack Developer

Please note that for this role you must be eligible for security clearance, so must have been a resident in the UK for a minimum of 5 years.
We are seeking a developer who wants to grow as part of an experienced engineering team, building secure, reliable and meaningful software used across complex public-sector and operational environments.

This role suits someone with a solid technical foundation, a hunger to learn, and a genuine interest in both front-end and back-end development. You do not need to be an expert in every area. What matters is that you enjoy building software, solving problems, communicating clearly, and improving through practical delivery.

You will work across back-end and front-end development, contributing to Java or Kotlin services, Spring Boot applications, REST APIs, integrations, databases, user interfaces, and platform improvements. You will be supported by senior engineers, trusted to take ownership of assigned work, test your changes, and contribute to shared engineering best practices.

This is a strong opportunity to gain practical experience across back-end services, front-end development, cloud-based delivery, and agile engineering practices, while building your confidence and technical ownership over time.

What you will do

• Build and maintain software features using Java or Kotlin, Spring Boot and modern web technologies, including RESTful APIs that support internal systems and integrations.
• Contribute to front-end development where needed, working with technologies such as HTML, CSS, JavaScript, TypeScript, React, Angular or AngularJS.
• Write clean, readable and maintainable code, working with relational and NoSQL databases to query, structure and manage data effectively.
• Support quality through unit, integration and functional testing, code reviews and defect resolution, with support from the team where needed.
• Use Git, build tools and CI/CD pipelines as part of everyday development, working closely with product, QA, design, DevOps and other engineers to deliver working software.
• Develop and apply good engineering practice across security, performance, accessibility and maintainability.

What we are looking for

• Around 2 to 5 years of software development experience, preferably in a commercial development environment, although capability and potential matter more than exact years.
• Hands-on experience with Java or Kotlin and object-oriented programming, with exposure to Spring Boot or similar backend frameworks, alongside working knowledge of relational and NoSQL databases.
• Familiarity with Git, collaborative development workflows, CI/CD pipelines and automated delivery.
• A test-first attitude, with a willingness to write and maintain automated tests as part of normal development.
• Ability to work well in an agile team, communicate clearly and take a practical, reliable approach to delivery.
• Genuine enthusiasm for technology, with a willingness to learn, improve and take on more technical ownership over time.

Desirable experience

• Experience or good working knowledge of Spring Framework, Spring Data JPA, Hibernate or similar backend technologies.
• Understanding of REST APIs and service-based development.
• Front-end development experience using HTML, CSS, JavaScript and ideally TypeScript, with knowledge of frameworks or libraries such as React, Angular, AngularJS or Vue, modern front-end patterns or legacy front-end modernisation.
• Exposure to cloud platforms such as AWS or Azure, with familiarity across containers, Kubernetes and CI/CD tooling such as Jenkins, GitLab CI or GitHub Actions.
• Experience with, or working towards, accessibility standards such as WCAG 2.2 AA.
• Experience working in secure, regulated or operationally sensitive environments.
