A World-Changing Company

Palantir builds the world’s leading software for data-driven decisions and operations. By bringing the right data to the people who need it, our platforms empower our partners to develop lifesaving drugs, forecast supply chain disruptions, locate missing children, and more.

The Role

Palantir’s impact and productivity in the UK Government (UKG) sector rely on our ability to navigate government and industrial security efficiently and responsibly. We are seeking a highly organized, security-focused professional to lead policy and process development and execution around personnel security and clearances, partnering closely with business leaders to support our mission.

As a Security Controller on Palantir’s UKG Security Team, you will:

• Manage the personnel clearance programme, secure facilities, and sensitive systems.

• Ensure compliance with security policies, regulations, and processes within complex organisations.

• Deliver exceptional knowledge and customer service to Palantir personnel, enabling them to drive the business forward.

In this multi-faceted role, you will also serve as:

• Crypto Custodian: Safeguarding digital and cryptographic assets, managing the full lifecycle of cryptographic materials, and maintaining robust security standards.

• Compartmented Security Officer: Implementing stringent security protocols for UKG’s most sensitive intelligence and acting as the primary liaison with UK Intelligence and Defence partners.

Join a team of tenacious, resourceful individuals who challenge conventional approaches and are committed to delivering faster, better outcomes for our customers. You will have the opportunity to shape security strategy, reimagine processes, and make a tangible impact on national security missions.
