What does it mean to work at Circle

CI? For us, flexibility is key.

The Web Experiences team owns the holistic user experiences where customers interact with Circle

CI. This team plays a critical role in shaping how customers perceive, adopt, and get value from Circle

CI — directly impacting retention and expansion.

You'll be building the interfaces and experiences that tens of thousands of developers use every day to understand their builds, manage their pipelines, and make decisions about their software. This means your work has an outsized impact on how Circle

CI feels to our customers. We care deeply about frontend craft, performance, and building interfaces that help developers move faster.

• Design & Build: Develop new frontend features and user experiences that shape how customers interact with Circle
  
  CI. Simplify existing interfaces and scale our systems as we rapidly grow and evolve.
• Write Code: Produce sustainable, testable, high-quality, and high-performance code — primarily in React and Type Script on the frontend, with backend contributions in Go.
• Own the Customer
  
  Experience:
  
  Work closely with Design, Product, and Data partners to translate customer insights into polished, performant interfaces that developers love using.
• Support & Maintain: Debug and support services in a complex distributed system. You care about how your code runs in production and are happy to dig into tools like Honeycomb, Datadog, Graylog, and Rollbar to understand and resolve issues.
• Champion Observability: Foster a culture of monitoring and observability by using operational data to help your team increase the stability, performance, and usage of our systems.
• Leverage AI: Use, document, and advocate for the use of AI tools like Claude/Cursor or similar for streamlined development workflows. Help the team adopt practices that accelerate their work through AI.
• Collaborate & Innovate: Partner with members of a cross‑functional team to dive deep into business problems, explore creative solutions, weigh design tradeoffs, and prioritize work to deliver maximum value incrementally.

• Experience: 3+ years of professional experience building and debugging production web applications and distributed systems.
• UX Expertise: Strong proficiency with modern frontend frameworks — React and Type Script are our primary stack. You have a sharp eye for UI/UX quality, accessibility, and performance.
• Full-Stack Versatility: While frontend-leaning, you're comfortable contributing to backend services in Go. You understand API design and can work across the stack when needed.
• System Design: Experience designing systems and leading projects from clarifying requirements through to delivery. You think about architecture, not just features.
• Code Quality: You write code that's easily readable, testable, maintainable, and documented, with observability baked in from the beginning.
• Production Mindset: You care about how your code behaves in production. You're comfortable with monitoring, debugging, and operating services in a complex distributed environment.
• Adaptability: You thrive in ambiguity — adjusting to changing priorities, making conscious tradeoffs when guidance is limited and information is incomplete, and instituting best practices when needed.

• Experience with modern frontend performance optimization, accessibility standards, and design systems.
• Knowledge of CI/CD tools, build systems, test automation, and deployment strategies.
• Experience working with LLMs or AI-powered engineering tools, including prompt design and practical application in development workflows.

• Consider themselves Product Developers — those who crave solving complex customer problems, not just generating code.
• Are super curious about how things work, new…
