Lead Solution Architect (TANTUS)

Technical Partnership with CMS

Serve as a primary technical point of contact for CMS stakeholders on architecture direction, modernization priorities, and emerging technology opportunities.

Translate CMS’s evolving mission needs into a forward-looking technical roadmap, and bring that roadmap back to CMS for validation and buy-in.

Represent SIO’s technical perspective in CMS governance forums, helping CMS leadership think through tradeoffs as they shape their own strategic technology direction.

Connecting Security, EA&I, and Shared Solutions

Identify where decisions in one function — a security finding, an architecture direction, a shared solution choice — should inform the others, and carry that alignment through into real, practical action across teams.

Support the SIO Innovation Council by surfacing ideas worth scaling and ensuring they’re evaluated with the right technical and security lens.

Maintain a working view of the technical roadmap spanning all three functions so dependencies and opportunities for reuse surface early rather than after the fact.

Strategic & Stakeholder Advisory

Advise program leadership and CMS stakeholders on technology trends, architectural tradeoffs, and modernization opportunities in clear, decision-ready terms.

Build trust-based relationships across CMS technical and program staff that support honest, two-way conversation about what’s working and what needs to change.

Communicate complex technical concepts in language suited to both technical staff and executive, non-technical audiences.

Technical Depth & Quality

Maintain hands-on technical depth that builds credibility in architecture and security conversations across all three functions.

Support secure, scalable, and reusable design practices across the three functions, escalating only where cross-team alignment is genuinely at risk.

Qualifications

• Bachelor’s degree in Computer Science, Engineering, Information Systems, or a related technical discipline.
• Master’s degree preferred.

• Strong communication and relationship-building skills, with a demonstrated ability to translate technical tradeoffs into terms a program or agency leader can act on.
• Experience in regulated or compliance-driven environments (e.g., healthcare, public sector); CMS experience strongly preferred.
• Working knowledge of cloud-based architecture, security-by-design principles, and modern delivery practices (Agile, DevSecOps) sufficient to engage credibly in technical conversations across all three functions.
• Prior experience in a client-facing technical advisory or architecture consulting role within a federal program.
• Familiarity with innovation governance models (e.g., innovation councils, technology evaluation frameworks).
• Familiarity with interoperability standards and data exchange frameworks relevant to CMS/CCSQ systems.
