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.

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 ...
