We are seeking an experienced Senior Software Engineer to help design and build next-generation AI systems used in Defence, Security, and Resilience environments. You will work on a cutting-edge multimodal data fusion platform that transforms large-scale information streams into operational decision advantage.
This role is ideal for a strong generalist engineer who enjoys working across distributed systems, AI infrastructure, semantic data representation, deployment engineering, and agentic AI architectures. You will take major platform components from concept through production, influence architectural direction, and help deliver systems capable of operating across cloud, edge, on-premise, and air-gapped environments.
You will collaborate closely with senior technical leadership, platform engineers, security stakeholders, and mission-focused teams to deliver robust, scalable, production-grade software.
What You’ll Do
- Design, build, and operate core platform components across the AI and data stack.
- Develop distributed systems that ingest, transform, and serve diverse multimodal datasets.
- Contribute to the development of agent frameworks and AI orchestration systems.
- Help define deployment architectures spanning managed cloud, customer cloud, edge, on-premise, and air-gapped infrastructure.
- Collaborate cross-functionally to standardise scalable data platform solutions.
- Work closely with security stakeholders to implement strong access control, data protection, and system integrity practices.
- Influence engineering standards, architectural decisions, and technology selection across the organisation.
- Support customer-facing mission deployments where required.
