CMM’s Platform Architecture team operates at a distinctive intersection: it shapes the engineering platform that serves every engineering team at CMM, while simultaneously embedding in the organization’s highest-priority, most technically complex initiatives to ensure those projects build on the platform as intended — and to bring what they surface back as first-class platform capabilities. The Principal Architect is the most senior individual contributor on this team, and that dual mandate is the core of the role.

This is a role for an architect who earns organizational influence through the quality of their thinking and the credibility of their recommendations. You will own architectural direction for key platform domains, develop and ratify organizational standards through the CMM Architecture Review Board, and serve as the embedded architectural partner on high-profile initiatives across value stream engineering. When your embedded work reveals a gap between what the platform offers and what teams need, you don’t hand it off — you translate it into a platform capability and drive it through.

This is not a review role that appears late and comments on completed designs. The value is being present early, trusted deeply, and able to change outcomes — on individual projects and on the platform that underlies all of them. This role reports to the Sr. Director of Platform Architecture.
** Key Responsibilities
**** Platform Architecture & Standards
*** Own architectural direction for CMM’s core platform domains, shaping platform investment decisions and establishing the technical standards that guide engineering teams across the organization.
* Develop and ratify CMM architectural standards through the ARB — researching problems, building options and rationale, and shepherding proposals through to adoption.
* Build and maintain reference architectures and reusable patterns that give engineering teams a trusted framework for common problems.
* Identify architectural debt, structural risks, and emerging gaps — and propose platform investments to address them before they become constraints or workarounds.
* Maintain and socialize a technology radar across CMM’s platform domains — a structured investment signal for what the organization should adopt, trial, assess, or avoid — and use it to inform multi-year platform architectural direction.
** Embedded Value Stream Partnership
*** Serve as the embedded architectural partner on high-profile initiatives — present early enough to shape decisions, not late enough to create blockers.
* Ensure new workloads are built using the platform as intended — applying established standards and avoiding workarounds that accumulate integration debt.
* Surface gaps between platform capabilities and project requirements early, translating them into platform capability proposals rather than project-scoped solutions.
* Stay close enough to the platform itself to identify when behavior diverges from intent and bring those findings back to the team.
** Technical Mentorship & Engineering Capability
*** Invest in the architectural capability of the broader engineering organization through design reviews, architecture guilds, and documentation.
* Help develop architects and senior engineers who think at platform-wide scope — building the organizational capacity to sustain architectural coherence at scale.
* Model the…
