Careers
Build intelligence systems that matter
Join us in building AI systems that transform how organisations make critical decisions in defence, intelligence, and strategic operations.
The work matters
At Sirca, we build intelligence infrastructure for organisations operating in complex, high-consequence environments. This isn't just a technical challenge, it's a mission that requires exceptional people working at the intersection of AI, operational intelligence, and strategic systems thinking.
We're solving genuinely hard problems: transforming fragmented, unstructured data into decision-ready intelligence for defence ministries, intelligence services, critical infrastructure operators, and strategic resource companies.
The systems we build affect operational safety, national security, and strategic decision-making at scale. Your work matters.
Our culture
Intellectual Rigour
We value clarity of thought, technical depth, and the ability to think systematically about complex problems.
Operational Excellence
We build systems for environments where reliability is non-negotiable. Attention to detail, operational discipline, and rigorous testing are fundamental to how we work.
Mission Focus
We're building intelligence systems that serve organisations with real operational responsibilities. The work requires understanding not just the technology, but the operational contexts where our systems deploy.
Trust & Discretion
Many of our partners operate in sensitive environments. Discretion, operational security discipline, and trustworthiness are non-negotiable.
The people we need
We're looking for people who:
Have deep technical expertise in AI, machine learning, systems architecture, or intelligence analysis
Understand (or want to understand) the operational realities of defence, intelligence, or critical infrastructure
Can think clearly about complex, ambiguous problems
Take ownership and operate with minimal oversight
Care about building things that matter
Experience in defence, intelligence, or national security contexts is valuable but not required. We care more about how you think and your ability to deliver operational systems than your CV.
Open positions
Machine Learning Engineer
