Principal Software Engineer 4 with TS/SCI + Poly

We believe the highest-impact work in national security and technology is a team sport.

At Aperio Global, we operate as a single, cohesive force aligned on a handful of mission-critical efforts where our work truly moves the needle.

We don't chase small wins.

We solve for next.

We view the intersection of cybersecurity, artificial intelligence, and data analytics as an empirical discipline as rigorous and consequential as any field in science or engineering.

That means we bring intellectual honesty, accountability, and transparency to every problem we take on.

Our team includes tech innovators, Intelligence Community veterans, and security professionals who know that the best solutions come from diverse minds working toward a common mission.

We value our people, those working quietly behind the scenes, doing the hard work that keeps our nation secure.

The best way to understand how we think is to see what we've built.

From full-spectrum cyber operations and de-biased AI platforms to quantum networking and cloud-native software systems, our work speaks for itself.

We offer competitive compensation and a comprehensive benefits package — including medical, dental, and vision coverage, a 401(k) retirement plan, life insurance, generous paid time off, short and long-term disability, professional development, and much more.

We invest in our people because they are our most important asset — and because the mission demands the best.
