Missions that matter

From frontline defence to new frontiers of space technology, SDI members work at the heart of some of the biggest challenges facing the world today. Whether helping to track the climate patterns that will shape our future, or backing our military to make timely, evidence-based decisions, our information solutions have never been more vital.

The systems we build respond to complex data networks at the largest scale and the smallest detail. We help our clients mitigate human impact on our world, and to sustain life on earth. If you’re looking for a career with purpose, you won't be disappointed.

Trust and confidence

We work collaboratively with global tech companies, cutting edge SMEs, academia and government agencies. We rely on the brightest minds and new perspectives to maintain our critical thinking community. Our approach is skills-first and we invest in you to succeed.

We support project's from the seabed to space and at all points in between, which translates into variety, fresh challenges and exposure to a range of experiences with global reach, and beyond.

Whether developing satellite software, integrating command and control platforms, or protecting vital systems, you’ll find a supportive and truly insight-led, outcome-based environment.
