Staff Performance Engineer

  • San Francisco, CA, USA
  • Full-time

Job Description

Optimizely is looking for engineers who want to turbocharge experimentation for our customers. Our goal is to be so fast we’re invisible, allowing customers to test their wildest ideas with minimal to  no overhead.

We’re looking for a very collaborative, senior systems-focused engineer to help own and run our performance infrastructure. Why collaborative? This is a position that puts you in touch with a lot of folks across Optimizely: customer-facing support, solutions architects, product managers, and engineers. Why senior? You’re working in a small team and building consensus across the organization; you’ll need to be able to translate problem statements into concrete solutions and lead projects through to completion. Why systems-focused? We have performance specialists across all our product engineering teams, and this role provides a lot of glue across those teams. A lot of times that glue involves shared infrastructure (or shared process).

What you will do

  • Work across engineering, product, and customer success teams to develop expertise on our unique performance needs

  • Build systems that shine light on performance issues (including gathering and visualizing telemetry data)

  • Educate our customers and customer-facing teams on how to experiment in a performant way that works for them

  • Develop infrastructure to provide high-speed experimentation for our customers

  • Organize, plan, and manage large projects through to completion


  • You find happiness in being a force multiplier for your colleagues

  • You look at engineering problems holistically

  • You know how to build and support large scale infrastructure (1000+ nodes, lots of traffic, latency sensitive, and fault tolerant)

  • You know how to make those large systems usable by humans

  • You stay on top of technical trends, and know how to use them pragmatically

  • You are self-motivated, yet still enjoy working in partnership across an organization

Some technologies we work with

  • Content Delivery Networks, like Akamai

  • Container-based technologies, like Docker

  • Continuous delivery and orchestration technologies, like Spinnaker and Jenkins

  • Continuous integration, log collection and analysis, builds, and performance monitoring

  • Monitoring and observability tooling

  • IaaS and PaaS providers like AWS, Google, and Heroku
