About Execution

The Execution team, embedded within the Foundations division, is tasked with ensuring that any job that has permission to run on our platform can be run immediately, reliably, with the appropriate resources and then handle the results from said job.

About Foundations

The Foundations division is the very heart of CircleCI; its teams build, own, and operate the collection of services that fully realize customer builds, from a trigger into a status out and everything in between. Teams within the Foundations division work on capabilities like user access and management, pipeline processing, orchestration, and job execution, focusing heavily on reliability, security, and performance.

What You’ll Do

• Design and build new features, simplify existing services, automate, and scale our systems as we continue to rapidly grow and evolve.
• Write sustainable, testable, high-quality, high-performance code.
• Support, maintain, and debug production microservices in a highly complex distributed system.
• Champion a culture of observability and monitoring by using operational data to help your team improve the stability and performance of our systems.
• Partner with members of a cross-functional team and other partners to set the direction of our platform and product: learn about our business problems, explore solutions, weigh design tradeoffs, and prioritize them to deliver maximum value in a sustainable, incremental fashion.

What You’ll Bring

• 5+ years as a full-time professional developer with experience building reliable, zero-downtime, observable distributed systems.
• The utmost care in regards to how your code runs in production. You're the kind of developer who's happy to dig around in tools like Honeycomb, Datadog, Graylog, and Rollbar and work out what needs to be done to address a problem.
• Ability to write code that’s easily readable, testable, maintainable, and documented, with an eye towards baking observability in from the beginning.
• Interest in improving the lives of our customers and the team, and can use just enough code with a keen eye on constraining complexity. We use Go primarily, but you'll also encounter JavaScript, Clojure, and even the odd bash script—all deployed into Kubernetes and as agents on our compute fleet.
• Ability to learn and think critically about both system design and software engineering concepts and blend those perspectives pragmatically based on project needs.
• Ability to quickly adapt when priorities change and make conscious tradeoffs with incomplete information.
• Bonus: Experience managing infrastructure as code on a public cloud.

We’re Particularly Interested In These Work Styles

• Working transparently and collaboratively within a distributed team.
• Favoring regular, incremental delivery over precision.
• Striving for continuous learning and improvement for yourself and your team.
• Passionate about ensuring that all of our systems—software and human—scale smoothly.
