At Sierra, weâre creating a platform to help businesses build better, more human customer experiences with AI. We are primarily an in-person company based in San Francisco, with growing offices in Atlanta, New York, London, Paris, Singapore, and Japan.
We are guided by a set of values that are at the core of our actions and define our culture: Trust, Customer Obsession, Craftsmanship, Intensity, and Family. These values are the foundation of our work, and we are committed to upholding them in everything we do.
Our co-founders are Bret Taylor and Clay Bavor. Bret currently serves as Board Chair of OpenAI. Previously, he was co-CEO of Salesforce (which had acquired the company he founded, Quip) and CTO of Facebook. Bret was also one of Google's earliest product managers and co-creator of Google Maps. Before founding Sierra, Clay spent 18 years at Google, where he most recently led Google Labs. Earlier, he started and led Googleâs AR/VR effort, Project Starline, and Google Lens. Before that, Clay led the product and design teams for Google Workspace.Â
Own frontend across product and marketing surfaces: You will work across both our core product interface and customer-facing web pages, ensuring a cohesive, polished user experience across all touch points. This includes building features in the web app and also collaborating on our website to keep branding and user experience consistent and high-quality.
Lead design system and UI components: Youâll design, build, and maintain a scalable design system and reusable component library that empowers all our engineers and designers. By delivering robust, high-quality UI components and infrastructure, you will ensure consistency and excellence across all product surfaces. Youâll also collaborate with designers to establish guidelines and patterns, enabling the team to rapidly build beautiful, consistent UIs with confidence.
Craft pixel-perfect user experiences: Work closely with our design team to translate Figma designs into reality with pixel-perfect precision and delightful interactions. You will partner with designers to refine UI patterns and ensure every detail is right â from typography and spacing to motion and hover states. We care deeply about design craft, so youâll sweat the details to build an interface that feels elegant, intuitive, and âjust rightâ for users.
Champion frontend excellence: As the senior frontend expert, you will set and uphold high standards for performance, accessibility, and code quality. Youâll optimize our frontend for speed (efficient loading, bundle size, smooth rendering) and ensure our product works flawlessly across browsers and devices. You will also incorporate best practices for accessibility and internationalization, making our product usable by all customers.
Move fast with pragmatism and quality: In our startup environment, youâll iterate quickly to ship improvements and new features. Youâll make thoughtful engineering trade-offs that balance rapid delivery with maintainability and polish. This means knowing when to build a quick solution and when to invest in the long-term path â always keeping user experience and business impact in mind.
Full-stack involvement: While your focus will be frontend, you should be comfortable venturing into the backend when needed. Youâll integrate frontend features with our GraphQL API and occasionally update server-side code (we use Go/gqlgen) to unblock frontend work. In short, youâll do what it takes across the stack to deliver a great end-to-end product experience â without ever sacrificing our high bar for UI quality.
Frontend expertise and modern skills: Extensive experience (5+ years) building world-class web interfaces using React, TypeScript, HTML and CSS. You have a proven track record of shipping polished user interfaces in production products . Bonus points if youâve worked with Tailwind or similar modern CSS frameworks for rapid development.
Design sense and attention to detail: You have a keen eye for good design and care deeply about the details of the user experience. We look for people who share our passion for software craftsmanship and getting even the smallest details rightâthis aligns with Sierraâs value of craftsmanship. You take pride in creating pixel-perfect, intuitive UIs and will proactively fix even minor UI issues because you value quality.
Strong collaboration and communication: You excel at working closely with designers and product managers to achieve the best outcome. You partner with product and design teams to craft beautiful user experiences , and you communicate clearly about tradeoffs and solutions. Youâre open to feedback and can articulate your ideas in discussions, ensuring everyone is on the same page.
Self-motivation and drive: You are intensely goal-oriented and proactive, able to take ownership of projects with minimal guidance. Youâve thrived in fast-paced environments and have a track record of delivering projects quickly and frequently. You can manage ambiguity and complexity, breaking down big problems into simple, workable solutions. In short, you get things done with speed and quality in equal measure.
Pragmatic problem-solving: You approach engineering with practicality. You make effective trade-offs between ideal solutions and pragmatic deliverables, always considering the user impact and long-term maintainability. Youâre not ideological about technology â you choose the best tool for the job and can learn new technologies on the fly as needed.
Front-to-back understanding: While specializing in frontend, you have a solid understanding of backend fundamentals. You know how web APIs, databases, and servers work. If needed, you can read and write server-side code. In particular, experience with GraphQL APIs and/or Golang (our backend language) is a plus for this role.
Design systems experience: Previous experience building or contributing to design systems or component libraries â either at a company or in open-sourceâwould be a big plus . This means youâve helped create shared UI frameworks with Figma.
UI/UX specialization: An eye for user experience beyond coding âe.g. some experience with user research, visual design, or interaction designâwould help you excel in crafting a delightful product. If youâve worked closely with UX designers or have design skills yourself, thatâs a bonus.
Domain experience: Exposure to AI or ML products, especially building UIs for complex data or AI-driven features. For example, if youâve built chat interfaces, analytics dashboards, or enterprise SaaS products before, youâll have useful relevant experience.
Full-stack prowess: Experience with our broader tech stack is helpful. This could mean familiarity with GraphQL (and libraries like gqlgen or Relay), Go or other back-end languages, and cloud platforms. While not required, such experience means you can hit the ground running across our codebase .
Startup mentality: Youâve been an early engineer at a startup or small team before. You understand the intensity and flexibility needed in a startup environment and are excited to wear many hats. If you love taking initiative and having a broad impact, youâll fit right in.
Trust: We build trust with our customers with our accountability, empathy, quality, and responsiveness. We build trust in AI by making it more accessible, safe, and useful. We build trust with each other by showing up for each other professionally and personally, creating an environment that enables all of us to do our best work.
Customer Obsession: We deeply understand our customersâ business goals and relentlessly focus on driving outcomes, not just technical milestones. Everyone at the company knows and spends time with our customers. When our customer is having an issue, we drop everything and fix it.
Craftsmanship: We get the details right, from the words on the page to the system architecture. We have good taste. When we notice something isnât right, we take the time to fix it. We are proud of the products we produce. We continuously self-reflect to continuously self-improve.
Intensity: We know
