Mobile Web Developer Jobs in Ontario (NOW HIRING)

Client & Mobile Foundations is the Platforms suborg that owns Pinterest's cross-surface client platform and quality stack, the shared Android, iOS, and Web foundations, build and release tooling, and quality systems that let product teams ship experiences faster and more safely. As a Staff Product Manager in the org, you'll set direction across core client architecture and paved paths on each surface; the mobile and client build systems, CI, and release tooling; and client quality and reliability from crash-free user rate (CFUR) and test infrastructure to release health, code coverage, and performance and app-size guardrails. You'll partner with client engineers, infrastructure teams, data scientists, and product leaders to deliver ready-to-use, best-practice foundations and developer experience including pioneering agentic tooling that automates migrations and test generation so every client engineer can ship high-quality, performant features quickly across iOS, Android, and Web.

What you'll do:

• Set and drive a multi-year strategy for Pinterest's client platform and quality stack across iOS, Android, and Web including the shared architecture, libraries, and paved paths product teams build on.
• Own the roadmap for the mobile and client build systems, CI, and release tooling that make shipping fast and safe across surfaces.
• Raise the bar on client quality and reliability, driving metrics like crash-free user rate (CFUR), release health, critical code coverage, and performance/app-size guardrails, along with the test infrastructure behind them.
• Define and champion agentic tooling that automates large-scale migrations and test generation, accelerating the full build/test/release lifecycle.
• Deeply understand your developer customers, where teams lose time, quality, or confidence, and define the developer-experience and platform-health metrics that measure impact.
• Lead complex, multi-phase migrations and consolidations that reduce fragmentation and improve reliability and performance across client surfaces.
• Partner across client engineering, infrastructure, and product, act as the spokesperson for the org, and mentor peer PMs (not a people-management role).

What we're looking for:

• 10+ years in product management or technical leadership, with a record of building and launching client platforms, developer-experience, or engineering-productivity products not solely consumer features.
• Direct experience owning one or more of: mobile/web client platform architecture, build systems and CI/CD, release/deployment tooling, or test infrastructure.
• Track record of improving client quality and reliability metrics  e.g., crash-free rate, release health, code coverage, app size, or client performance.
• Strong technical breadth and judgment across mobile (iOS/Android) and web; able to go deep with engineers on architecture tradeoffs and technical risk.
• Demonstrated success leading large, multi-phase technical initiatives including migrations, architecture redesigns, or system consolidations across many teams.
• Experience with agentic / LLM-powered developer tooling (migrations, test generation, codegen) is a strong plus.
• Analytical and strategic mindset; comfortable making high-accountability decisions and defining metrics that prove impact.
• Exceptional communication and influence at all levels, from individual engineers to senior executives.
• Bachelor's degree in Computer Science, Engineering, or equivalent practical experience; advanced degrees a plus.
