About the role
The National Security business in Gloucester is growing and there are an increasing number of opportunities to work with a range of National Security clients to provide solutions that have a real impact.
Be part of a growing team that not only delivers for its clients but also gives back to the community with plenty of opportunities to get involved with local community engagement and outreach activities to help build tech and cyber skills in the region.
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 Dev Ops/SRE community within the organisation;
What background are we looking for?
Typically have experience in the following:
Software development in Java and web technologies, e.g. JavaScript and HTML
Familiarisation with database technologies such as Elastic, Mongo
Know your way around Linux and Windows command lines, e.g. Bash and Power Shell
Hands on experience with cloud infrastructure such as AWS, Azure or Open Stack
Use of deployment tools such as chef and puppet
Expertise in monitoring large systems using technologies such as ELK

Experience of working in an Agile scrum team, and the tooling that supports it, e.g. Jira
Diagnosing and troubleshooting application issues resulting in service outages
Troubleshooting skills across different levels of the stack
Understanding of ITIL terminology

Experience with container management and micro-services architectures such as Docker
Experience extending and improving Open Source Software
Familiarisation with automation test frameworks such as Selenium
Awareness and insight into technology trends to adopt new cutting edge tools
