ITV is the largest commercial broadcaster in Europe, operating a family of channels in the UK, and producing content for our own channels and third parties around the world. The ITV Hub is the home of ITV's catch-up and live content online, with over 17 million registered users and 1+ billion plays per year.

 

Responsibilities

  • You'll be responsible for ensuring we always give our viewers a great experience, even at the busiest times
  • You’ll work with the teams that build and run our services
  • You'll develop a deep understanding of all the moving parts and how they interact
  • Use your experience and performance tests to uncover any problems before they affect our users
  • Because a large proportion of our viewers watch live, the demands on the systems that power the Hub when a popular show starts are enormous. This could mean an audience of millions all pressing play simultaneously, with the consequential requirement for testing that accurately simulates this sudden surge
  • Performance problems often span multiple systems so you’ll need to have experience working in a distributed environment and chasing bugs across the boundaries between different parts

About You

  • You’ll have a deep understanding of performance testing, including the common pitfalls and challenges
  • You should know when a concurrent user figure is appropriate, and when it’s meaningless
  • You should know why the rate of transactions starting isn’t always the same as the rate finishing, and what that means
  • An important skill is being able to gauge the nature and magnitude of a workload for a completely new service or an upcoming show by mixing historical data, forecasts from different groups
  • Using common sense to get a good idea of the type and scale of testing required
  • A large part of this role is communication - with Engineering teams to understand and improve services, and with management to explain issues and risks
  • You must be comfortable discussing technical details as well as presenting high-level summaries
  • You must be familiar with load testing tools (eg Jmeter, Gatling
  • Experienced in building load tests
  • An expert at running performance tests and interpreting the results
  • Comfortable working with basic statistics
  • Happy working within agile product teams
  • You should be aware of modern cloud-based architectures
  • You should be able to share your expertise across the whole ITV Hub team
