At CircleCI, we enable thousands of developers to do better work every day. We're looking for full-stack folks to nurture the systems that make it possible.

The Core mission is to provide best-in-breed Continuous Integration and Continuous Delivery. As a Core member, you’ll own essential microservices and build features at the heart of our platform: Orbs, Pipelines, permissions, our data model, and the CLI, for example. You’ll also collaborate daily with talented colleagues across North America and western Europe.

This is a full-time role at the E3 level, and requires participation in our on-call support rotation.

What You’ll Do:

• Design and build new features, simplify existing services, and scale our systems as we rapidly grow and evolve.
• Write sustainable, testable, high-quality, high-performance code.
• Support, maintain and debug microservices in a complex distributed system.
• Foster a culture of observability and monitoring: use operational data to help your team increase the stability, performance, and usage of our systems.
• Partner with members of a cross-functional team and other stakeholders to set the direction of our product: learn about our business problems, explore solutions, weigh design tradeoffs, write effective user stories, and prioritize them to deliver maximum value in a sustainable, incremental fashion.

What we're looking for:

• 3+ years of full stack professional experience building and debugging distributed systems in production environments.
• You write code that’s easily readable, testable, and maintainable, with an eye towards baking observability in from the start.
• You enthusiastically approach everything from HTML/CSS to API design with the same level of respect and intention. You don’t need to be an expert in everything; T-shaped folks with an emphasis on frontend skills are ideal for these roles.
• You’re interested in learning new languages and technologies. We use JavaScript/React, Go and Clojure, MongoDB and PostGreSQL, and RabbitMQ, but it’s okay if you haven’t yet. You can find more details on our tech stack here.
• You’re good at navigating and shaping the dynamics of a rapidly-growing company with a remote-first culture: quickly adapting when priorities change and making conscious tradeoffs with incomplete information.

We’re Particularly Interested In People Who:

• Work transparently and collaboratively within a distributed team.
• Favor regular, incremental delivery over perfection.
• Strive for continuous learning and improvement for themselves and their teams.
• Are excited about ensuring that all of our systems—software and human—scale smoothly.
