Principal Staff Software Engineer, Systems Infrastructure - Experimentation Platform

Principal Staff Software Engineer, Systems Infrastructure - Experimentation Platform

At LinkedIn, every change to the products and services is rigorously tested through experiments to assess their impact on the members and metrics. These experiments are gradually scaled up to evaluate their effects at each stage before moving forward. We conduct thousands of such experiments daily across all product offerings resulting in millions of evaluations on the platform, and it is crucial that the results and insights are reliable.

To facilitate this, LinkedIn has established a centralized experimentation platform used by all engineering teams to launch new services or product features with an experimentation flag. This platform allows them to set up experiments, scale them safely, observe results, and gain insights into statistical significance and metric impact. The stability, reliability, and observability of these platforms are paramount. Continuous evolution of the tech stack is essential to support the scale of thousands of experiments. Additionally, as we integrate more AI/ML workloads, the experimentation platform must evolve to meet these new demands. The goal is to transition from a manual design, execution, and reporting process to a fully automated, AI-assisted experience, to drive an increase in experimentation velocity.

This role will be based in Bangalore, India. At LinkedIn, our approach to flexible work is centered on trust and optimized for culture, connection, clarity, and the evolving needs of the business. The work location of this role is hybrid, meaning it will be performed both from home and from a LinkedIn office on select days, as determined by the business needs of the team.
