Web Developer, Marketing Site

At Sierra, we’re building a platform to enable every company in the world to build better, more human customer experiences with AI. We partner with industry leaders such SoftBank, Uber, Rivian, CLEAR, and Sutter Health. We are primarily an in-person company based in San Francisco, with growing offices across North America, Europe, and Asia. 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 Google’s AR/VR effort, Project Starline, and Google Lens. Before that, Clay led the product and design teams for Google Workspace.

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. Build content infrastructure that unblocks the team: You'll develop our CMS (we use Sanity) to give content and marketing teams self-serve tooling, structured content models, and preview/staging workflows, so routine changes don't depend on engineering. You'll design content schemas and editing experiences that let non-engineers move quickly and confidently. Champion growth: You'll partner with marketing, sales, and operations to implement analytics and enable experimentation, turning business goals into shipped, instrumented features so we always know what's actually working. Make localization first-class: You'll support localization and internationalization — multilingual content, translation workflows, and the infrastructure behind them, so non-English experiences are genuinely first-class rather than afterthoughts. Treat performance as a feature: You'll own Core Web Vitals, media and asset optimization, and the diagnosis of the subtle issues: layout shift, lazy-loading, video quality, render timing. You care about speed, and you measure it. Hold a high bar for accessibility: You'll champion semantic markup, keyboard navigation, screen-reader support, and WCAG-minded component design, ensuring the site is usable by everyone who visits it.

Marketing and growth fluency: You've worked on marketing or growth-facing web before, and you understand the business context — funnels, conversion, SEO, analytics, and A/B testing—not just the code. We care about this more than years of experience or exact seniority. Strong frontend fundamentals: You're fluent in modern JavaScript and TypeScript and React (or a similar framework), with a real sense for UI/UX craft and an instinct for getting the small details right. A genuine commitment to performance and accessibility: You care about both deeply and can point to specific, concrete things you've done to improve them in production. Comfort with structured content: You've worked with a headless CMS and structured content models before. Sanity experience is a plus. Strong cross-functional collaboration: You work well with non-engineers — designers, content writers, and marketers — and can translate their goals into technical work, and technical tradeoffs back into terms they can act on. Even Better... Localization and i18n experience: You've worked with internationalization systems and translation tooling before. Analytics and experimentation
