Job description

LinkedIn is the world’s largest professional network, built to create economic opportunity for every member of the global workforce.

Our products help people make powerful connections, discover exciting opportunities, build necessary skills, and gain valuable insights every day.

We’re also committed to providing transformational opportunities for our own employees by investing in their growth.

We aspire to create a culture that’s built on trust, care, inclusion, and fun – where everyone can succeed.

Join us to transform the way the world works.

At LinkedIn, every change to our products and services is rigorously tested through experiments to assess their impact on our 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 our product offerings resulting in millions of evaluations on the platform, and it's 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 our tech stack is essential to support the scale of thousands of experiments.

Additionally, as we integrate more AI/ML workloads, our experimentation platform must evolve to meet these new demands.

Our goal is to transition from a manual design, execution, and reporting process to a fully automated, AI-assisted experience, to drive increase in experimentation velocity.
