Platform Architect

• Think at a systems level and can design integrated, enterprise-scale platforms rather than isolated solutions
• Are passionate about DevSecOps, secure SDLC, and platform engineering in regulated/DoD environments
• Understand how to architect platforms for AI/ML and M&S workloads while maintaining strict compliance
• Can translate policy and compliance requirements into practical, automated technical guardrails
• Are comfortable evaluating and governing AI-assisted development tools in a secure, compliant manner
• Communicate clearly with both technical and non-technical stakeholders and can drive consensus
• Can shift between strategic architecture work and hands-on problem solving
• Are self-directed, collaborative, and committed to continuous platform and process improvement

• Your essential job functions will include but may not be limited to:
• Own the end-to-end architecture of the Development Platform, including SDLC workflows, CI/CD, source control, artifact management, observability, and associated tooling.
• Define and maintain SDLC and DevSecOps architecture patterns, reference designs, and guardrails for application, AI/ML, data, and M&S workloads.
• Architect and drive implementation of compliance-by-design capabilities (policy-as-code, compliance-as-code, automated evidence generation) so that developers operate within guardrails without manual effort.
• Lead the technical integration and governance of AI coding augmentation tools (e.g., AI-assisted code completion, review, and refactoring) to safely accelerate development while protecting sensitive data and meeting all compliance requirements.
• Define platform capabilities that specifically enable AI/ML and M&S workflows (e.g., data pipelines, model training/serving, simulation workflows) within the same secure SDLC and CI/CD patterns.
• Establish architectural patterns for multi-environment, multi-level security use of the Development Platform, including secure promotion paths from unclassified to classified environments.
• Provide architectural guidance for standardized CI/CD pipelines, reusable templates, and shared components used across engineering teams using various tech stacks.
• Partner with Cybersecurity SMEs to ensure security and compliance frameworks (NIST, RMF, CMMC, SSDF, etc.) are accurately reflected in platform design and technical controls.
• Collaborate closely with DevSecOps engineers, software teams, data/AI engineers, and cloud engineers to ensure architecture is implemented correctly, maintainable, and scalable.
• Define and document platform roadmaps, technical standards, integration patterns, and interface contracts.
• Mentor engineers on platform architecture, secure SDLC, DevSecOps best practices, and effective use of AI-assisted development within established guardrails.
• Coordinate with vendors and internal stakeholders to evaluate tools, plan upgrades, manage technical risk, and ensure the Development Platform remains modern, secure, and sustainable.
• Oversee platform reliability, performance, and scalability at the architectural level, ensuring the Development Platform can support growing AI/ML, M&S, and software workloads.

• 14+ years of progressive experience in software engineering, DevOps/DevSecOps, or platform engineering, including significant architecture and/or technical leadership responsibility.
• Demonstrated experience architecting and operating enterprise Development Platforms or software delivery platforms that integrate CI/CD, source control, artifact repositories, and observability tooling.
• Strong expertise in DevSecOps and secure SDLC practices, including automated testing, security scanning, and policy-as-code/compliance-as-code approaches.
• Hands-on experience with modern DevOps/DevSecOps toolchains, with substantial professional experience using GitLab as an absolute requirement.
• Deep experience working with Azure Cloud Services (absolutely required), including networking, IAM, storage, AI, and compute services.
• Strong background in Kubernetes and container orchestration, including cluster architecture, multi-tenant design, security controls, and GitOps-based deployment models (e.g., Helm, Kustomize, Argo CD).
• Proficiency with Infrastructure as Code tools (e.g., Terraform, Ansible, Packer, Puppet, or Chef) and configuration management patterns for repeatable platform provisioning and management.
• Demonstrated ability to interpret and apply security and compliance frameworks (NIST 800-53, RMF, CMMC, SSDF, etc.) to platform design and technical controls.
• Familiarity with SDLC and platform requirements for AI/ML and/or M&S workloads (e.g., data pipelines, model lifecycle, simulation workflows) in secure environments.
• Experience evaluating and/or integrating AI-assisted development tools, with an understanding of associated security, compliance, and governance considerations.
• Solid understanding of networking, identity and access management, TLS, secrets management, and zero-trust principles as they apply to enterprise development platforms.
• Proficiency in at least one relevant programming (e.g., Python, C#, Go, or similar) to support automation and integration efforts.
• Proven experience leading technical decision-making, producing architectural documentation, and presenting platform solutions to both technical and non-technical audiences.

• US Citizenship required.
• Ability to obtain and maintain a DoD security clearance; an active clearance is strongly preferred.
