Job Description

About Buildkite

At Buildkite, our mission is to unblock every developer on the planet. We've rethought how software delivery should work and have built a platform that is fast, reliable, secure, and able to scale to the needs of the most demanding high-growth tech companies globally including Uber, Airbnb, Shopify, Canva, PagerDuty, Lyft, and Pinterest.

Our engineering teams work across AU/NZ and US Pacific time zones — a deliberate choice that lets us move fast with real-time collaboration. At the moment, we are prioritising engineers who are based in the AU/NZ region.

In this role, you'll own the engineering response to the hardest problems our customers run into. You'll work inside the Pipelines team — partnering closely with Support, TAMs, and Solutions Architects — to take escalations from symptom to root cause, ship fixes back into the product, and remove the underlying causes of recurring tickets.

This is a deliberately different role from the traditional support engineering hamster wheel. We're not looking for someone to just clear tickets faster. We're looking for someone to own the space — to spot patterns, drive systemic fixes, and make Buildkite stickier and more reliable for the customers who depend on it most.

🚀 What You'll Do

• Own L3 escalations end-to-end — from symptom through diagnosis to a shipped fix
• Work in our Ruby on Rails monolith and PostgreSQL databases to resolve issues at the source
• Spot recurring patterns in support load and ship product changes that eliminate the underlying cause — the best support ticket is the one that never gets opened
• Partner with Support, TAMs, and Solutions Architects on technical diagnostics for high-impact customers
• Lead the engineering side of incident response when production issues require deeper investigation
• Help improve the onboarding and migration experience for customers moving onto Buildkite from other CI/CD platforms
• Take customer wins from intake to delivery — own them, follow through, don't drop the ball
• Contribute to architectural discussions on platform reliability and customer experience
• Provide or respond to feedback on GitHub pull requests

🎨 What You Bring

• 5+ years of experience in engineering
• Comfortable working in a Ruby on Rails monolith — able to read, debug, and modify production code confidently
• A track record of taking problems from symptom to root cause without losing focus or scope
• Pattern recognition — you see recurring issues and propose systemic fixes rather than one-off patches
• Comfortable in customer-facing conversations when escalations require it — can triage in real time, communicate clearly, and give customers confidence they're in the right hands
• Comfortable with performance at scale — N+1 queries, indexing strategies, diagnosing slow paths
• Experience using observability tools like Datadog, Honeycomb, etc.
• Care about code quality and know how to balance perfect with practical
• Calm and consistent under high volume — finish what you start
• Understand good development practices: clear commits, thoughtful pull requests, and reliable tests with tools like RSpec

Key Technical Stacks & Components:

• Ruby on Rails
• PostgreSQL
• GraphQL
• React
• Datadog
• Amazon ECS
• RDS Performance Insights
• Terraform
• Redis
• Kafka
