Analyze experiment results and product usage data with Data Analysts to decide which changes to keep, iterate on, or roll back based on first-purchase outcomes.
Collaborate with Product Managers and UX Designers to define hypotheses and success metrics before shipping experiments, then compare results against those metrics.
Maintain and improve our experimentation framework and tooling to increase experiment throughput and reduce the time from setup to results.
Collaborate with other Engineering teams, including Fulfillment, to remove purchase barriers across GitLab’s codebase.
Document decisions, review code, and share experiment results asynchronously so distributed teammates can track shipped changes and their measured outcomes.
Take part in on-call or operational support where your team’s ownership model requires it.
What you'll bring
Professional experience developing with Ruby on Rails and modern JavaScript, along with solid Git, feature development, and deployment workflows.
Experience working with relational databases and a solid understanding of web performance optimization.
A track record of shipping features to production and owning them after release.
Ability to use product data to decide what to build, keep, or roll back.
Ability to document decisions and share updates asynchronously with distributed Product Management, UX, and Data teammates.
Ability to organize your work, seek and apply feedback, and collaborate inclusively with teammates from diverse backgrounds, in line with GitLab’s values.
Preferred, not required: experience with Vue.js, PostgreSQL, A/B testing, feature flags, experimentation frameworks, or SaaS sign-up, trial, billing, or checkout flows. We'll help you learn our tooling.
