CircleCI is seeking a Software Engineer passionate about maintaining and crafting the future of services that power the heart of our product. You’ll work across a deep slice of our system on features and capabilities ranging from:
- Orchestrating and scheduling jobs.
- Introducing new execution environments across our platforms: Docker (Nomad), EC2 and GCP.
- Maintaining and enhancing the runtime environments, reusable configurations, and integrations that customers rely on.
- Keeping our large multi-tenant, multi-platform fleet of build servers, distributed cloud infrastructure and generally instrumenting our environments to be running reliably and securely.
- Help craft the end user testing environments we offer to our customers.
- Debugging complex issues across the platforms we support.
- Storing customers caches, artifacts, test results and step output.
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.
What You’ll Do:- Improve and automate legacy build processes for machine images, convenience images, and certified orbs.
- 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 through rapid iteration and design exploration, weigh design tradeoffs, and prioritize them to deliver maximum value in a sustainable, incremental fashion.
- 3-5 years as a professional developer with experience building reliable, zero-downtime, observable distributed systems using Go, our primary programming language. You'll also encounter bash, JavaScript, and Clojure - all deployed into Kubernetes and as agents on our compute fleet.
- You write code that’s easily readable, testable, maintainable, and documented. You also have familiarity with observability tools like Honeycomb, Datadog, and Rollbar, and understand how to use that information to address problems in production.
- Experience using AI-assisted development workflows to accelerate iteration, explore design and SDK interfaces, and debug complex systems, while keeping a commitment to correctness, performance, and long-term maintainability.
- Experience with Packer, Ansible, and other DevOps tools and workflows.
- Experience working in open-source projects and interacting with customers through bug reports and pull requests.
- Working transparently and collaboratively within a distributed team.
- Favor toward 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.
