About the Organization
Now is a great time to join Redhorse Corporation. We are a solution-driven company delivering data insights and technology solutions to customers with missions critical to U.S. national interests. We’re looking for thoughtful, skilled professionals who thrive as trusted partners building technology-agnostic solutions and want to apply their talents supporting customers with difficult and important mission sets.

About the Role

~4 min read

Redhorse transforms the way government uses data and technology. To support our most sensitive Intelligence Community (IC) mission partners, we are seeking a Contract Security Officer (CSO) with an active Full Scope Poly (FSP). 

Unlike a traditional corporate security role, this position is mission-embedded. You will serve as a strategic security partner directly supporting the customer’s operational environment. You will be the primary bridge between technical mission teams and government security authorities, ensuring that security protocols act as an enabler—not a barrier—to delivering innovative digital solutions. Your work will directly impact the speed and security at which our IC customers can deploy critical capabilities. 

  • Mission Integration: Serve as the primary security advisor to Government Program Managers (GPMs) and technical leads, ensuring security requirements are integrated into the earliest stages of mission planning. 
  • Customer Liaison: Act as the direct point of contact between Redhorse mission teams and the Government Security Office to expedite clearances, program access, and facility authorizations. 
  • Personnel Security (PERSEC) Acceleration: Manage the full lifecycle of mission-critical personnel security actions, including SCI processing and Full Scope Polygraph coordination, specifically tailored to the customer's priority mission sets. 
  • Operational Security (OPSEC): Develop and implement mission-specific OPSEC plans to protect sensitive customer activities, methodologies, and technical implementations. 
  • SCIF & Facility Management: Provide expert oversight of customer-designated Sensitive Compartmented Information Facilities (SCIFs), ensuring physical security, access control, and technical security standards meet ICD 705 requirements. 
  • Contractual Security Advisory: Interpret and implement DD254 requirements for specific mission contracts, providing guidance on classification levels and handling instructions for unique mission data. 
  • Security Education for Mission Teams: Deliver targeted Security Education, Training, and Awareness (SETA) briefings that address the specific threats and vulnerabilities associated with the customer’s technical environment. 
  • Incident Response & Reporting: Lead the investigation and reporting of security incidents within the customer’s program space, coordinating closely with government oversight bodies to mitigate risks to national security. 
  • Audit & Inspection Readiness: Ensure the customer’s program area remains in a constant state of inspection readiness for government-led security reviews.
  • Active Top Secret/SCI clearance with a Full Scope Polygraph (FSP) is required. 
  • 5+ years of experience in industrial or government security, with a focus on supporting embedded mission operations within the IC. 
  • Deep expertise in IC security standards, specifically ICD 704, ICD 705, and the NISPOM Rule (32 CFR Part 117). 
  • High proficiency in IC-specific systems: Detailed experience with Scattered Castles, DISS, and agency-specific security portals. 
  • Customer-Facing Experience: Demonstrated experience supporting security operations directly for the IC customers. 
  • Exceptional Communication: Ability to brief and advise government executive leadership and senior technical staff on complex security risks. 
  • Agile Problem Solving: Proven ability to find compliant solutions to complex security challenges that arise during technical mission execution. 
  • Certified CSSO (Contract Support Security Officer) or equivalent government security certification. 
  • Technical Familiarity: Understanding of the Risk Management Framework (RMF) to better support ISSMs/ISSOs in securing mission-critical IT systems. 
  • Project Management Skills: Ability to track multiple moving parts of a mission security program simultaneously. 
  • Redhorse Corporation is an equal opportunity employer. All qualified applicants will receive consideration for employment and will not be discriminated against on the basis of race, color, religion, sex, sexual orientation, gender identity, national origin, veteran status, disability, or any other protected class.
