Help Build the Next Generation of Defense Software
How do you build Java software when thousands of business rules, operational processes, and assets all depend on each other?
At ILIAS Solutions, complex business rules, large volumes of operational data, and interconnected processes come together in one integrated platform. A change in one process can directly affect asset availability, qualifications, maintenance activities, logistics processes, and operational readiness.
Built with Java 21 and our migration towards Java 25, Spring Boot, REST APIs, PostgreSQL, Oracle, React, Docker, Git, Maven, Jenkins, SonarQube, and Mend, the platform continues to evolve through new capabilities and increasingly complex requirements.
This is not another standard business application and it is not about building isolated microservices. It is about understanding how systems interact, translating complexity into software, and building solutions that remain reliable, scalable, and maintainable over time.
The software supports critical operational processes used by defense organizations around the world.
For developers who enjoy staying close to the code, solving difficult problems, and taking ownership from analysis through implementation, this environment offers technical depth, complexity, and the opportunity to help shape the next generation of the ILIAS platform.
Meaningful Work in a Mission Driven Environment
Turning Operational Complexity into Trusted Software
Defense organizations operate in environments where personnel, qualifications, maintenance activities, equipment, and logistics processes are closely connected.
Decision makers depend on accurate information to understand whether people are qualified, assets are available, and operational objectives can be achieved.
A commander may need visibility into whether personnel, equipment, and supporting resources are ready for a planned mission. A maintenance manager needs insight into asset availability. A logistics specialist relies on accurate information to support operational planning.
Your work helps transform large amounts of operational information into software that provides clarity, confidence, and actionable insight.
Complex Challenges, Clear Solutions
Understanding Before Building
Customers rarely arrive with detailed technical specifications. They arrive with operational challenges.
Success in this role comes from understanding how processes, systems, people, and business rules interact within a larger operational environment. You analyse workflows, identify dependencies, uncover exceptions, and understand the logic behind operational decision making.
You use these insights to independently design, develop, and deliver software functionality. You take ownership of user stories from analysis through implementation and remain closely involved in the design, development, testing, and maintenance of software components.
You work closely with architects, analysts, and product owners to ensure that solutions fit both the operational reality and the technical direction of the platform.
While understanding operational complexity is important, this remains first and foremost a hands on Senior Java Developer role. We are looking for someone who enjoys building software, stays close to the code, and brings recent experience developing enterprise applications in modern Java environments.
The Impact You Help Create
Building Confidence Through Reliability
Behind every readiness dashboard, maintenance workflow, qualification record, and operational report are people who rely on accurate information.
Your work helps ensure that users can trust the information they receive and make decisions with confidence.
That trust is built through secure design, thoughtful engineering, clean code, and a long term focus on quality.
You take pride in building software that continues to deliver value as the platform evolves.

In defence operations, timing and reliable information shape every decision. Many organizations still rely on fragmented systems, limiting visibility and slowing execution. ILIAS Solutions connects logistics, maintenance, and operations into one integrated platform. This creates a single source of truth and enables teams to act on real time data across strategic, operational, and tactical levels. Large volumes of operational data move continuously between systems. This data reflects maintenance cycles, logistics flows, and asset readiness. Accuracy and consistency directly impact operational outcomes.
