DAZN - Senior OTT UI Engineer - React.js (8-10 yrs)

Your team :

The Player Engineering domain is one of the most crucial parts of the DAZN stack.

We build, own, and support the frontend playback experience across customers' devices at DAZN.

We strive to deliver the best possible video experience across all devices (web, set-top boxes, TVs, games consoles, mobiles) regardless of network conditions.

To do this we build everything from our own tooling and automation applications to test and evaluate devices to our own complex heuristics to ensure that we deliver the highest quality video streams to customers as often as possible based on their network conditions.

The way we work :

We obsess over data and use it to measure how we are performing against our customers' and the business' expectations, as well as using it to build our backlog and to inform where we should focus our development e- orts.

We value agile delivery practices and are continually evolving and reviewing our processes.

Delivery teams are typically made up of around 5-8 Engineers, a Team Lead, and a Product Manager. Our teams are from various and diverse backgrounds, and we welcome and encourage new perspectives and opinions openly.

Whilst we welcome anyone with experience in the streaming or OTT industry, it is by no means a prerequisite to work on this team.

Successful engineers are people who love to solve challenging problems and enjoy the opportunity to work on a variety of features and devices.
