Senior Software Engineer

Octopus Deploy sets the standard for Continuous Delivery, empowering software teams to deliver value in an agile way. Over 4,000 organizations globally – including Ubisoft, Xero, Stack Overflow, NASA, and Disney – rely on our Continuous Delivery, GitOps, and release orchestration solutions. We’re a profitable scale-up of 300+ people, growing steadily. We’ve built a high-trust, remote-first, and value-driven culture where people are given space to do their best work. About the role We’re looking for a Senior Software Engineer to join our Build Foundations team, reporting to an Engineering Manager. The team is multi-disciplinary, with Software Engineers, Site Reliability Engineers, and a Principal Engineer distributed across Australia and New Zealand. Build Foundations owns our build systems, release pipelines, and internal tooling, running over 1.7 million builds per year. Our mission: provide a reliable, observable build platform so Octopus R&D teams can ship high-quality changes quickly and safely. As a Senior Software Engineer at Octopus (L3), you’ll take meaningful slices of work from idea to production, make pragmatic trade-offs around reliability and maintainability, and help raise the bar for the engineers around you. A typical week might include:

Build and improve internal tooling and modules in C# that help teams ship faster and with fewer surprises

Strengthen build and release pipelines so deployments are smooth, repeatable, and easy to reason about

Improve reliability and operability through better defaults, automation, and observability

Partner with engineers across R&D to remove friction from builds, tests, deployments, and infrastructure workflows

Contribute to incident response and operational support to minimise downtime and speed up recovery

Work with tools like Azure, Terraform, Kubernetes, Honeycomb, Sumo Logic, and some AWS (plus AI-assisted tools where they help)

What we’re looking for:

You find joy in helping other engineers go faster.

Strong experience shipping production-quality C# and taking work from idea to production#

You enjoy automating builds, tests, deployments, infrastructure, and operational tasks.

Comfort operating software in production: you design for reliability, diagnose issues, and improve systems over time

Practical experience with modern delivery and infrastructure practices (e.g., pipelines, IaC, Kubernetes, cloud platforms)

Good engineering judgement: you make sensible trade-offs on scaling, reliability, maintenance, and technical debt

A “help others go faster” mindset: you unblock teammates, share context, and lift the team through reviews and mentoring

Clear, kind communication in a remote-first environment (written and verbal)

Ownership without ego: you take responsibility, learn from mistakes, and take on the necessary unglamorous work when it matters

Why you'll love this role:

Work on internal platform foundations that shape how Octopus engineers build, ship, and operate software every day

Solve infrastructure and reliability problems through code, with a software engineering mindset

Join a supportive team that values collaboration, learning, and sustainable pace

On-call (paid, supported, and humane): you’ll join our on-call program once you’re confident in our systems (typically after 6 months), with training and documentation provided. Coverage is 24×7, and you receive an allowance of 5% of base salary when on the program, and teams usually roster no more than ~2 weeks in every 8 per person.
