Position Overview & Specifications

Overview

Site/Application Reliability Engineer


As an SRE, you will look to help the different parts of our organisation to work together through better communication and collaboration. In conjunction with our Service Delivery Engineers, you will help to build out the appropriate Service Level Objectives (SLOs) and Service Level Indicators (SLIs).
Our customers want us to move faster than ever before. As an SRE, you will promote frequent releases, continually updating the product and keeping team members on their toes about new and relevant technology. You will encourage us to move quickly by reducing the costs of failure.


At SITA, we are meeting the new needs of travel...today! Are you ready to join us?


What you will do:

  • safeguard, support, and advance the software and systems they are responsible for
  • proactively help to monitor capacity, performance, latency, and availability of the products they are responsible for
  • increase the reliability and efficiency of the products they are responsible for
  • help shape and deliver any cloud migration strategies of the products they are responsible for
  • own log and secret management, project dockerisation, and the continuous integration and delivery pipelines for the products they are responsible for
  • ensure monitoring and observability tooling and methods are adopted consistently across the business
  • work with development, infrastructure, operations, support teams to deliver the above
Qualifications Benefits that you will bring to the areas of the business that you work with:
  • Modernise - given an SREs comprehensive viewpoint and deep understanding of contemporary technologies and best practices, the SRE can modernise the products’ end-to-end delivery pipelines, ensuring we are able to deliver faster and to a higher quality than we do now (yes it is 100% possible to deliver faster with higher quality)
  • Early prevention on issues that can affect end users - Tight iteration and development cycles and production releases not only let us be one step ahead in the market but also mitigates various problems such as bug and vulnerability detection early.
  • Enhanced monitoring - SREs will endeavour to comprehend the systems they are using and, using automation and machine learning, e.g. build a procedure wherein alarms are automatically forwarded to whoever is most qualified to resolve them. SREs remove these problems through proactive troubleshooting.
  • Enhanced metrics reporting - clarity around end-to-end metrics relating to bugs, efficiency, production, overall service health, and other factors.
  • Generate more time for DevOps teams to, well, develop - DevOps teams will have a lot more time to devote to developing new features and enhancements if the error detection and resolution process was more effective and deployment pipelines faster and more automated (they will need to do far less baby-sitting)
  • Better Operations responsiveness - freeing up operations teams to do direct configuration, testing, and maintenance.
  • Focused on improving the customer experience - the SRE drives continuous improvement via empirical data. Maintaining SLA/SLO/SLIs. This is stuff is not the remit of the delivery teams.
  • Continuous Cultural improvement - SREs offer ongoing search of areas of improvement to optimise services and products reliability
  • Increased automation - SREs continuously find the best way to automate and modernise workflow of product engineers. At the same, they also improve their workflow by detecting vulnerabilities and bugs early. Thus, automation will increase the reliability of services or systems.
