Principal Technical Program Manager, Performance

Lead company-wide performance improvement programs across mobile, web, and infrastructure platforms. Partner with engineering leaders to drive measurable, durable changes in speed, reliability, and user experience quality.

About the job

What You'll Do

Partner with Client Platforms, product engineering, Infrastructure, data science, and senior technical leaders to translate performance strategy into executable programs across mobile, web, and shared platform systems.

Define and drive the operating model for sustained performance improvement, including how teams prioritize work, how success is measured, how regressions are prevented, and how risks are escalated or resolved.

Drive the organizational change required for performance to become a durable part of Reddit’s engineering culture, moving teams from reactive efforts to shared standards and repeatable mechanisms.

Develop communication and enablement mechanisms that bring engineers and leaders along for the journey, including leadership forums, working groups, documentation, decision reviews, and clear narratives that connect performance work to user and business outcomes.

Build measurement systems that distinguish real user experience improvement from shallow metric movement.

Drive performance governance and adoption in a way that preserves team ownership while ensuring user experience, reliability, release quality, experimentation discipline, and business guardrails are not afterthoughts.

Use technical judgment to challenge assumptions, identify systemic risks, and guide tradeoffs across client architecture, observability, experimentation, release health, and production reliability.

Who You Are

14+ years of experience across technical program management, engineering, infrastructure, client platforms, mobile or web platforms, performance engineering, reliability, observability, or related technical domains.

Led multi-year, multi-organization technical programs with executive visibility and ambiguous ownership.

Deep fluency in performance and reliability systems: client platforms, app health, observability, experimentation, release quality, user journey measurement, infrastructure, or production readiness.

Highly data-driven with ability to build measurement systems that connect technical improvements to user, business, and engineering outcomes.

Exceptional cross-functional operator and communicator who builds trust across functions and translates complex technical and organizational change into clear narratives.

Led meaningful organizational change, shifting behavior across teams by listening to concerns and making the desired path easier than the status quo.

Preferred Qualifications

Experience leading performance, reliability, client platform, mobile platform, web platform, infrastructure modernization, observability, or experimentation programs at large scale.

Experience with mobile or web performance, including app startup, rendering, media delivery, networking, caching, crashes, hangs, release quality, or user journey performance.

Experience building durable operating mechanisms after incident, war room, or Code Yellow style mobilizations.

Experience with experimentation systems, holdouts, guardrail metrics, and tradeoff decisions where user experience, engagement, and business metrics need to be evaluated together.

Experience building adoption strategies for internal platforms, observability systems, performance tooling, or engineering practices.
