Envitia is recruiting for a Java Engineer to join our Security and Intelligence consulting team and will be responsible for designing, developing and maintaining secure software services and mission applications within classified government environments.

The role focuses on building high-performance backend systems, microservices and APIs that enable intelligence data platforms, analytics systems and operational applications.

The successful candidate will work within multi-disciplinary agile teams, collaborating with data engineers, data scientists, DevOps engineers and mission analysts to deliver secure, production-grade software systems.

Typical engagements include:

• Developing Java-based microservices and backend platforms
• Building API-driven services enabling data exploitation and analytics
• Supporting distributed analytics platforms and intelligence applications
• Integrating software components across complex secure environments
• Delivering cloud-native and containerised mission software systems

Responsibilities

• Design, develop and maintain secure Java‐based backend services supporting mission‐critical and operational systems.
• Build scalable microservices architectures and robust RESTful APIs to support data‐driven and intelligence platforms.
• Engineer high‐performance, distributed applications capable of processing large volumes of data with low latency and high reliability.
• Integrate Java applications with data platforms, streaming services and analytics pipelines, including AI/ML‐enabled systems.
• Apply secure coding practices and ensure solutions meet stringent performance, reliability and security requirements.
• Contribute to architectural design, code reviews, automated testing and continuous improvement activities.
• Implement logging, monitoring and observability to support the operation of production systems.
• Collaborate closely with multi‐disciplinary teams including engineers, data specialists and operational stakeholders.

Skills

• Strong experience developing Java‐based backend applications (Java 11+) using modern frameworks such as Spring Boot / Spring Framework.
• Solid understanding of object‐oriented design, software architecture and building RESTful APIs.
• Experience designing and developing distributed systems and microservices architectures, including service‐to‐service communication and API integration patterns.
• Proven ability to build high‐performance, scalable backend systems for data‐intensive or mission‐critical applications.
• Experience working in DevSecOps environments, including Docker, Kubernetes, CI/CD pipelines, automated testing and observability tooling.
• Ability to work directly with stakeholders to understand requirements and translate them into robust, secure and scalable software solutions.
• Strong collaboration and communication skills, with the ability to explain technical concepts to both technical and non‐technical audiences.
• Comfortable working in secure or regulated environments, delivering software within complex operational constraints.

The successful candidate must be eligible for an enhanced Developed Vetted / eDV security clearance.
