Job Description

At Optimizely, the Distributed Systems platform is the foundation driving our Experimentation and Personalization products, providing the information that our customers need to understand their experiment results.

  • Create a Reliability Engineering roadmap to ensure that our complex, large-scale systems, and services are highly available, performant, monitored, automated and designed to scale.
  • Influence new Data services and features early on so they are designed with scale, operability and performance in mind.
  • Deliver launch plans for major features and build the necessary infrastructure (staging environments, monitoring, alerting etc) that will support the launch with operational run-books.
  • Drive the team through “Disaster Recovery Tests” where we will manually turn down pieces of infrastructure and services to test Optimizely’s overall resiliency to failures.
  • Build tools and smart alerting that can discover failures/issues quickly, with the goal of automating response to non-exceptional service conditions. 
  • Plan for growth of our services. Build out ahead of increased capacity needs and forecast demand
