Full-Stack Software Engineer, CircleCI

• 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 TypeScript 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
