Implement security and identity controls across platform environments, including RMF, STIG compliance, vulnerability management, ADFS/SAML integration, and least-privilege access
Establish observability, monitoring, logging, incident response, and reliability practices to maintain platform security, performance, and operational stability
Support secure infrastructure for AI-native workloads and LLM foundation model testing, incorporating platform-level security controls, auditability, and data protection
Develop reusable platform architectures, infrastructure accelerators, and engineering standards that can be adopted across teams and client engagements
Advise government stakeholders and delivery teams on technical architecture, risks, implementation decisions, and trade-offs while balancing security, scalability, operational costs, and delivery timelines
Mentor engineers, guide technical decisions, and champion engineering practices that improve delivery consistency, efficiency, and team capabilities

REQUIRED SKILLS & EXPERIENCE

10+ years of relevant professional experience in platform engineering, cloud infrastructure, DevSecOps, systems engineering, or related technical disciplines
Deep hands-on experience designing and improving secure CI/CD pipelines using Jenkins, GitLab, Artifactory, and related technologies, with demonstrated success increasing deployment frequency, automation, and delivery reliability across teams or engagements

Experience implementing identity and access management solutions, including ADFS/SAML, least-privilege principles, and secure authentication and authorization
Experience implementing infrastructure monitoring, logging, alerting, incident response, and reliability practices in complex environments
Experience supporting AI-enabled workloads or LLM foundation model testing, with an understanding of relevant infrastructure, security, and operational considerations
Demonstrated technical leadership, including architectural decision-making, establishing reusable engineering standards, and translating security and mission requirements into scalable solutions
Strong client-facing communication and advisory skills, with the ability to explain technical trade-offs, set realistic timelines, collaborate across teams, and mentor engineers
Must currently possess or be able to obtain CompTIA Security+ CE or another DoD-approved IAT Level II certification within 30 days of hire
