Senior Software Engineer

Adarga builds AI systems for customers working in Defence, Security and Resilience. With a core focus on our multimodal data fusion platform, we combine the value of humans and agents to transform information overload into decision advantage.

Our team is a hybrid of domain specialists and technologists. We believe this layering of experience is key to building cutting edge AI that is operationally relevant. With our foundations set in NLP, computational linguistics and graph technology we now draw on the latest ideas in agentic AI and knowledge representation, as we set our sights firmly on defining and building the next era of sovereign AI capability.

To work at Adarga you have to care deeply about the mission. We exist to support those with the ultimate task: upholding the liberties and values that define our society.  We want people who are comfortable with uncertainty, who want to own decisions, who want to drive a vision.

Adarga is seeking an experienced generalist engineer to advance the design and implementation of our multimodal data fusion platform. You will take significant components from design through to production, contribute to architectural decisions, and ship. You will work alongside our Chief Architect and a growing engineering team, contributing across the full surface area of the platform: data ingestion, transformation pipelines, semantic data representation, agent frameworks, and the deployment stack that takes our software from cloud to edge to airgap. We are a cross-functional team and on occasions you will also be expected to deliver on specific customer projects as part of a Mission deployment.
