Person looking at points around a globe

Infrastructure Engineer (Mid / Senior)

Build tools for the best
software teams in the world.

About The Role

We are looking for an Infrastructure Engineer to help us scale one of the biggest Postgres-powered Rails majestic monoliths in the world. We are experiencing tremendous growth and have the vision to unblock every development team in the world with our products. 

We run on AWS, we're deep into observability using Datadog, moving to immutable infrastructure using Fargate, doing interesting partitioning with Postgres, and improving our deploy tools so multiple teams can safely deploy our monolith multiple times per day. You’ll join an established team to help level up Buildkite’s scale and reliability.

On a typical day, you could be…

  • Adding a canary stage to our deploy pipeline so mistakes are detected before they impact customers

  • Consulting with team members to improve how we diagnose and fix the operational aspects of their software systems

  • Refactoring parts of our production infrastructure using terraform and pull requests to enable our growth

  • Iterating on Ruby (Rails) code in our primary app, and any related changes to our PostgreSQL database

  • Troubleshooting our production app and isolating issues to fix

  • Carefully shifting more of our workload to Fargate

  • Video calls with others on the team to discuss or solve problems, or to just say hi

  • Providing feedback on a GitHub pull request, or responding to feedback left for you

  • Working to manage and improve on-call and incident response processes

  • Engineering solutions to improve the reliability and availability of our platform

Skills and experience we like...

  • Experience writing and maintaining zero downtime database migrations

  • Familiar with patterns for increasing the safety of deploys, like smoke tests, canaries, and blue/green deploys

  • Enjoy thinking about the challenges of safely deploying both code and config changes

  • Strong communicator that values empathy and kindness when articulating your ideas and feelings when writing or speaking

  • Understand development processes. You are comfortable writing git commits, pull requests and issues. You know how to critique others code in a positive and productive way, and are comfortable receiving the same sort of feedback

  • Comfortable working remotely, leveraging asynchronous communication, working by yourself and taking the initiative to improve anything and everything

  • Learn fast. You might not be an expert in everything we do initially, but you will quickly become an expert in some aspects. You are comfortable diving in and learning things, even if they are new to you

Why Apply?

Small team, global impact

We believe small companies are beautiful, and that small teams can achieve big things. This makes everyone on the team an important part of Buildkite.

Flexible work hours

We don’t keep set office hours, so you can shift your hours around life’s commitments and non-work activities. Take time out of work for exercise, family or whatever life throws at you.

Support and growth

In a small but growing company, you’ll have the opportunity to work on a wide range of projects, and ship work that helps customers.

Work from anywhere

We’re a globally distributed company, and all our work happens remotely. Work from your home office, a co-working space, or your local cat café.


Learning & development

Invest in your personal and professional development with a yearly budget to spend on travel, conferences, workshops, courses, and books.

Health cover

We’ll make sure that you and your family have access to comprehensive health and hospital cover, no matter which country you live in.

Parental leave

Take time out to set up a new family, with 6 months of paid leave if you’re the primary carer, and 3 months if you’re secondary. You can use it flexibly, change between primary and secondary, and take the same leave for a still birth. We also keep paying super/401k for 6 months if you take unpaid leave.

Home office & coworking

Set yourself up with a great work environment, either at home or in a co-working space, with a budget for a desk and chair, and a new computer and phone every 24 months. We’ll also cover the cost of plants, art, or anything else you need to set yourself up with a beautiful and productive work environment.

Wellness & paid time off

Take care of your health and wellbeing away from the screen, with 6 weeks of paid leave per year, the ability to take time out of work for fitness, and a yearly budget to spend on things like yoga, climbing, personal training, or a day at the zoo.

Profit share & ownership

Share in the company’s success, and have a stake in what you’re helping to build. Everyone on the team receives a percentage share of the company profits each quarter, and an equity stake through our employee share program.

Working at Buildkite has given me the freedom to grow and flourish in all aspects of my life, personally and professionally. I’m proud to be a part of such a passionate and supportive team.
