Responsibilities

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
