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 systems and translation tooling before.

- Analytics and experimentation depth: You're familiar with web analytics and experimentation platforms and know how to use them to drive decisions.

- Third-party integration experience: You've integrated services like video hosting or error monitoring into a content workflow.
