Web Developer, Marketing Site at Sierra in San Francisco, CA

Job description

About us Sierra is the leading platform for customer-facing AI agents, working with many of the world's biggest brands — including The GAP, Rocket Mortgage, SoFi, Sutter Health, and SoftBank — to transform how they serve customers and grow their businesses. 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 a commitment to balancing Family along the way. 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. What You'll Do: • 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. What You'll Bring: • 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
