Senior Software Engineer

Senior Software Engineer - Execution CircleCI seeks an experienced Senior 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. 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. Helping 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. You’ll collaborate daily with dedicated colleagues across the world. This is a full-time, fully remote role that requires you to participate in our on-call support rotation as well as incident management. 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 and focus 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 making 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. 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.
