Job Description

About the Role

Security at CoLab isn't a compliance exercise. It's a core part of earning and maintaining the trust of some of the world's largest engineering organizations.

As a Senior Security Analyst , you'll help shape the future of our enterprise security program. You'll be a key member of our Blue Team, responsible for protecting CoLab's cloud infrastructure, corporate systems, and customer data while continuously improving how we detect, investigate, and respond to threats.

This is a hands-on technical role reporting to our CISO. You'll spend time investigating alerts, leading incident response efforts, refining detection capabilities, improving security controls, and helping teams make sound security decisions before problems emerge.

You won't be handed a mature playbook and asked to follow it. You'll help build it. If you enjoy solving complex security problems, taking ownership, and balancing strong technical judgment with practical business decisions, you'll likely find this role rewarding.

Our Ideal Candidate

You're the type of person who sees an alert and wants to understand the full story—not just close the ticket.

You can move comfortably between technical investigation, risk discussions, and stakeholder communication. During an incident, you're calm, methodical, and focused on facts. Afterward, you're just as interested in improving systems and processes to prevent it from happening again.

You'll thrive here if you enjoy:

• Solving difficult security problems with incomplete information
• Taking ownership of outcomes, not just tasks
• Learning continuously as technologies and threats evolve
• Working closely with Security, Technology, and Product teams
• Balancing strong security practices with business realities

Job Responsibilities

• Create and maintain security documentation, standards, and operational procedures
• Contribute to security awareness efforts and provide guidance on secure business practices
• Stay current on evolving threats, attacker techniques, and defensive technologies
• Authorizes/approves user access to CoLab
• Coordinates with relevant CoLab AI teams for program functions wholly or partially implemented at the corporate level (i.e., general security training)
• Develops and maintains an accurate and up-to-date System Security Plan (SSP) Package for the FedRAMP -designated system
• Distributes copies of SSP Package elements to relevant team members, on a need-to-know basis
• Designates key personnel as responsible for core program functions (i.e., incident handling, disaster recovery, etc.)
• Receives operational alerts, updates, and status reports from team members and critical system components
• Oversees the Continuous Monitoring Program for CoLab
• Reports the security and privacy state of CoLab to external entities (i.e., Customer Agencies, FedRAMP Program Management Office (PMO) , Third Party Assessment Organizations (3PAOs)
