Engineering Manager, Experiment Platform Team

Overview

Join the Wikimedia Foundation in our mission to make Wikipedia and other projects better at freely sharing the sum of all knowledge. We are building a privacy-preserving experimentation platform to enable data-driven decisions across our products at a global scale. The Experiment Platform Team is actively developing and maintaining this infrastructure, providing product teams with A/B testing, feature flags, and experiment analysis capabilities. This platform will empower over 10 product teams across the Wikimedia Foundation to test product decisions through privacy-preserving experimentation.

Job Description

As the Engineering Manager for the Experiment Platform Team, you will lead a small, high-performing team of engineers in building the experimentation platform. This role offers an exciting opportunity to shape the platform's architecture and capabilities. You will collaborate with product analytics teams, SRE, and data engineering to ensure the platform meets the needs of product teams while upholding the highest standards for privacy, reliability, and performance. In close partnership with the Product Manager, you will translate product vision into technical roadmaps, balancing feature requests from product teams with the platform's reliability and scalability requirements.

This is a fully remote position. Some travel is required 2–3 times a year for off-sites and other events.
