Job description

As a Senior Site Reliability Engineer, you will be responsible for the reliability of a large international SaaS environment running primarily on Microsoft Azure. The platform operates across more than 10 global data centres, serves millions of end users and needs to deliver 24/7 availability backed by strict SLAs.

This is not a traditional operations or ticket-driven infrastructure role. You will approach reliability from an engineering perspective. You define and manage SLOs and error budgets, improve observability, automate repetitive work and design systems that can recover automatically when something goes wrong.

You will work closely with cloud engineers and software development teams. Instead of only becoming involved after an incident occurs, you will participate early in the development process and help engineering teams make architectural decisions that improve scalability, performance and reliability.

What will you do?

• Define and manage SLOs and error budgets for critical services across the Azure environment
• Identify operational toil and replace repetitive manual work with automation and self-healing solutions
• Improve and standardise observability, including metrics, alerting and tracing
• Lead complex production incidents and facilitate blameless postmortems
• Translate lessons from incidents into structural improvements and automation
• Improve CI/CD and progressive delivery through safe deployments, canary releases and automated rollback
• Manage capacity, performance and infrastructure cost forecasting across the platform
• Build reliability automation using technologies such as Python and Terraform
• Introduce AI agents and bounded automation into detection, diagnosis and remediation
• Work proactively with product and engineering teams to incorporate SRE principles into new solutions from the design stage

Who are you?

You are an experienced engineer who enjoys taking ownership of complex production environments. You don't just want to keep systems running; you want to understand why problems occur and engineer them out of the environment.Ideally, you bring:

• Around 5+ years of experience as a Site Reliability Engineer, DevOps Engineer, Cloud Engineer or Infrastructure Engineer
• Hands-on experience managing production cloud environments, preferably Microsoft Azure
• Experience working with SLOs, error budgets and reliability engineering principles
• Strong knowledge of observability and monitoring, for example Grafana, Prometheus or similar tooling
• Hands-on Kubernetes experience, including areas such as Helm, ingress, RBAC and persistent volumes
• Experience with Terraform and Infrastructure as Code
• Experience using Python or another language for automation
• Experience working with CI/CD environments
• The confidence to take ownership during production incidents and participate in an on-call rotation
• Strong communication skills and the ability to document technical decisions, incidents and architecture clearly

About the organization

You will join an international software company that develops service management software for organizations across sectors such as government, education, healthcare and industry.

The organization employs more than 700 people across eight international offices, while its software is used by more than 10 million users worldwide.

The working environment is characterized by limited hierarchy, significant individual responsibility and close collaboration between engineering teams. Technology and innovation are central to the organization, with continuous investment in its SaaS platform, automation and the adoption of AI within both its products and engineering processes.

What do we offer?

• Salary up to €102.000,-
• 32 to 40-hour working week
• Hybrid working, including a home office allowance
• A pension scheme with employer contribution
• A personal development budget for conferences, certifications, and courses
• A Vitality Budget of €50 per month for sports, gym membership, or other things that contribute to your mental and physical health
• Travel expense reimbursement or an NS Business Card, plus the option to lease a bicycle through the company
• A senior technical position with significant ownership
• The opportunity to work on an international SaaS platform used by millions of users
• 10% of your working time dedicated to personal development
• A personal development budget equivalent to 10% of your gross annual salary
• A modern laptop and phone
