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.
Core Responsibilities

• Implement and maintain robust security processes and data protection measures, ensuring organisational compliance with government standards, supporting security clearance and vetting, promoting a strong security culture, and contributing to risk management and mitigation initiatives.
• Collaborate effectively with internal teams and external stakeholders to coordinate security activities, maintain records, deliver training, and support organisational security objectives.
• Oversee the full lifecycle and security management of cryptographic materials and digital assets, including procurement, inventory control, secure storage, distribution, disposal, policy compliance, auditing, incident response, and liaison with internal and external stakeholders.
• Deliver user support and ensure organisational readiness by maintaining personnel clearance records, providing training, conducting briefings, and offering expert guidance on the handling, movement, and security of cryptographic materials in line with UKG and organisational standards.
• Lead the management and protection of classified materials and secure facilities, overseeing secure handling, access control, physical and information security systems, SOP development, personnel vetting, incident response, and compliance with UKG standards for sensitive intelligence.
• Serve as the principal liaison with the UK Intelligence and Defence Communities, coordinating inter-agency security activities, providing expert guidance on highly classified security, and ensuring seamless integration of intelligence security requirements across the organisation.

What We Value

• Previous experience in a security-related role within government, defence, intelligence, or regulated environments is highly desirable. Experience managing classified materials, audits, compliance, and physical security systems is advantageous.
• Exceptional organisational, communication, and record-keeping skills. Strong analytical, problem-solving, crisis management, and interpersonal abilities. Able to brief, train, and work effectively at all levels and across teams.
• High integrity, discretion, trustworthiness, and the ability to work both independently and collaboratively, with a proactive approach to incident response and stakeholder liaison.

What We Require

• Must hold or be eligible for DV and Compartmented clearance, with the ability to handle highly classified materials.
• Completion of (or willingness to complete) UKNDS Crypto Custodian and Compartmented Security Officer training. Strong understanding of UKG security policies and vetting processes.
• Ability to be present on-site at a given facility within a 60-minute response time, with potential on-call duties during after-hours, weekends, and holidays.
