Job Description

About the Role

At Sierra, we are building a platform to enable every company in the world to create their own autonomous AI agents for various applications, from customer service to commerce. We are primarily an in-person company based in San Francisco, with growing offices in Atlanta, New York, and London. Our culture is guided by values such as Trust, Customer Obsession, Craftsmanship, Intensity, and Family. Our founders include Bret Taylor and Clay Bavor, who have extensive backgrounds in leading tech companies and AI initiatives.

Key Responsibilities

  • Own frontend across product and marketing surfaces: work on core product interfaces and customer-facing web pages to ensure a cohesive, polished user experience and maintain branding consistency.
  • Lead design system and UI components: design, build, and maintain a scalable design system and reusable component library, collaborating with designers to establish guidelines and patterns.
  • Craft pixel-perfect user experiences: translate Figma designs into high-quality, delightful interfaces with attention to detail in typography, spacing, motion, and interactions.
  • Champion frontend excellence: set and uphold high standards for performance, accessibility, and code quality, optimizing frontend speed and ensuring cross-browser/device compatibility.
  • Move fast with pragmatism and quality: iterate quickly to ship improvements and features, making thoughtful trade-offs between rapid delivery and maintainability.
  • Full-stack involvement: integrate frontend features with GraphQL APIs, occasionally update server-side code in Go, and do what it takes across the stack to deliver a seamless product experience.

Requirements

  • Extensive experience (5+ years) building web interfaces using React, TypeScript, HTML, and CSS with a proven track record of shipping polished user interfaces.
  • Strong design sense and attention to detail, with a passion for software craftsmanship and creating pixel-perfect, intuitive UIs.
  • Excellent collaboration and communication skills, able to work closely with designers and product managers and articulate tradeoffs and solutions.
  • Self-motivated, goal-oriented, proactive, and capable of managing projects with minimal guidance in fast-paced environments.
  • Pragmatic problem-solving skills, making effective trade-offs considering user impact and long-term maintainability.
  • Solid understanding of backend fundamentals, including experience with web APIs, databases, and servers; familiarity with GraphQL and Go is a plus.

Nice to Have

  • Experience building or contributing to design systems or component libraries, either professionally or in open-source projects.
  • Experience with UI/UX design, user research, visual or interaction design, especially if working closely with UX designers.
  • Exposure to AI or ML products, especially building UIs for complex data or AI-driven features like chat interfaces or analytics dashboards.
  • Experience with our broader tech stack, including GraphQL libraries like gqlgen or Relay, Go, and cloud platforms.
  • Startup mentality, with experience as an early engineer in a startup or small team, understanding the need for flexibility and initiative.

Qualifications

  • No specific formal educational qualifications are explicitly mentioned in the description.
