What you could be doing for us: As an SRE, fundamentally you will be doing work that has historically been done by an operations team, but using software and systems engineering expertise to use automation to reduce human labour, limiting traditional manual operations work (incident tickets, on-call etc.) to no more than half of the SRE team's time. Core role accountabilities include: * Supporting and maintaining essential service that support core mission applications, proactively enhancing their availability, performance and stability; * Finding innovative solutions to problems rather than undertaking repetitive work, automating everything you can. You will work alongside product teams, advising them of good practice in how to design and build systems, learning from what you know works well. And you will never be asked to spend more than 50% of your time on support (otherwise the product team supports the excess work until the support work returns to 50% or less); * You will instrument applications where they don't have sufficient monitoring in place, and use the output of it to demonstrate the improvements your team are making on a daily basis. You will be well versed in the relationship between software and infrastructure, understanding the characteristics of systems that enable them to be scalable and resilient to failure, and how to get the best out of the infrastructure they are deployed to; * Participating in the wider DevOps/SRE community within the organisation ## Related Videos - [The Resilience of the World Wide Web](https://www.wearedevelopers.com/videos/1281-the-resilience-of-the-world-wide-web) - [Improving quality with Agentic AI with Rovo Dev and Xray](https://www.wearedevelopers.com/videos/2005-improving-quality-with-agentic-ai-with-rovo-dev-and-xray) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Navigating the Corporate Jungle: Life as a Developer in a large Company](https://www.wearedevelopers.com/videos/621-navigating-the-corporate-jungle-life-as-a-developer-in-a-large-company) - [NoLoJS - Avoiding JavaScript Cruft with HTML and CSS - Aaron T.
