OTT delivers an exciting range of internet TV products that’s revolutionising the industry, with fresh ideas and the latest technologies.

Joining us in the Reliability Engineering team you will be at the core of ensuring that we deliver all these fantastic products at an industry beating level of availability and performance.  

Background

Site Reliability Engineering (SRE) is what you get when you treat operations as if it’s a software problem. Our mission is to progress, protect, and provide for the software and systems behind all of Sky’s public services – NowTV, SkyStore, SkyGo, to name just a few - with an ever-watchful eye on their availability, latency, performance, and capacity. 

This is an unusual job, unlike others in the industry. Like traditional operations groups, we keep important, revenue-critical systems up and running  We hire people from both systems and software backgrounds. Strong candidates will have experience with both. 

In SRE, we flip between the fine-grained detail of disk driver I/O scheduling to the big picture of service capacity, across a range of systems and a user population measured in millions. We drive reliability and performance across massive scale by mastering the full depth of the stack. 

As a Software Engineer on the Persistence Reliability Engineering team, you will have the opportunity to tackle the complex problems of scale while using your expertise in coding, algorithms, complexity analysis and large-scale system design

Key Responsibilities:

Our benefits package is designed to recognise the essential part you play in Skys success. We offer free Sky+HD, broadband and talk services; private medical insurance, generous holiday entitlements, a contribution pension scheme, a Share scheme so you can have a stake in Sky and our success plus Sky Choices a benefit scheme to help you make valuable tax & national insurance savings.

It’s our people that make Sky the UK and Irelands leading entertainment company. That is why we work hard to be an inclusive employer, so everyone at Sky can be their best.

If you are appointed to this role you will be subject to the successful completion of a Criminal Record Check.
