Senior Site Reliability Engineer

The Builds team at Octopus Deploy is looking for a Senior Site Reliability Engineer (SRE) to:

• Share SRE expertise with teams across the company.
• Keep our build systems running with high reliability and availability.
• Improve and iterate on our existing reliability practices.
• Bring fresh ideas and practices to increase reliability and reduce toil.
• Lead the implementation of new capabilities.

You’ll be a great fit if you:

• Naturally work in line with our Senior SRE expectations.
• You collaborate effectively, even across wide organisational distances, to solve problems, combining passion, pragmatism, and empathy.
• Thrive in an environment focused on availability, reliability, and observability.
• Are a strong systems engineer and may have deeper expertise in particular domains.
• See value in applying safety culture lessons from other industries to software and operations.
• Are comfortable leading postmortems and designing deployment and monitoring pipelines.
• Care deeply about automation across builds, tests, deployments, infrastructure, and operational tasks.
• Embrace a “you build it, you run it” culture, with a strong commitment to quality and system availability, and are happy to participate in a humane on-call program.
• Are self-motivated, work independently with high-quality output, and proactively seek help or new work when needed.
• Are results-oriented, adapt quickly when business direction changes, and encourage the same in others.
• Welcome candid feedback, enjoy solving complex problems, and like helping other engineers succeed while working on genuinely valuable projects.

Our tech stack

• You don’t need to know all of this – it’s here to give you a feel for our environment.

Octopus Server

• Our primary focus and flagship product.
• Written in .NET and backed by a SQL database.
• Experience with the C# application SDLC (e.g. building, testing) is highly regarded.

CI/CD

• TeamCity is our primary build system for Octopus Server.
• GitHub Actions is used for some internal tools.
• Continuous delivery is powered by Octopus Deploy.

Workloads

• A mix of internally developed applications and third-party software (e.g. TeamCity).
• Run in Azure using App Services, AKS clusters, and Azure Functions.
• Container workloads run on AKS, with Docker Hub and Artifactory as container registries.

Infrastructure as Code (IaC)

• Terraform is our primary IaC tool.
• IaC workloads run mostly in Octopus Deploy, with some running via GitHub Actions.

Observability

• Our team operates a multiregion OpenTelemetry processing system for the rest of R&D.
• We’ve adopted OpenTelemetry across many of our Builds systems.
• We help other teams adopt OpenTelemetry for more use cases company-wide.
• We use Sumo Logic and Honeycomb for analysis and troubleshooting.

A typical day might include:

• Building new capabilities to increase reliability (we don’t want you staring at dashboards all day).
• Working where you do your best work – from your home office, with your preferred setup, tools, and soundtrack.
• Consulting with another team on how to operate their services at the right level of reliability, or how best to use our build and observability platforms.
• Pairing with another engineer over Zoom to solve a complex technical problem or explore the problem space for future improvements.
• Responding to an actionable alert and working to maintain the reliability of the platform used across the company.
• Improving documentation so engineers can discover solutions themselves and reduce lead time.
• Writing a blog post or preparing a talk to share something interesting you’ve learned with other engineers.
• Facilitating an incident review and turning the learnings into practical changes.
• Proactively reducing toil by building thoughtful automation.
