Provide holistic architectural oversight for all major strategic programs to ensure individual solutions are aligned and reusable. Partner with stakeholders and Business Analyst leads to "shape demand," and ensure new programs are architecturally vetted for feasibility, impact, and strategic fit.

Mentor the Lead Solution Architect and Lead Technical Architect in the creation and adoption of robust and reusable design patterns and frameworks. Compliance, Security & Risk Management Partner directly with GRC, Audit, and Cyber Security teams to design and embed compliance controls (e.g., SOX, PSM for privileged access) directly into the Software Development Lifecycle (SDLC).
