Fullstack Engineer (Marketing)

Join a small, ambitious team where your work shapes how customers first discover and fall in love with our product. You'll be a frontend-first engineer with the full-stack depth to own our entire marketing site stack - from CMS and analytics to backend services and deployment. You're a proactive builder and problem solver who doesn't wait to be told what to fix; you spot opportunities, propose solutions, and ship them. No two days look the same: some days you're in the creative weeds with Design, obsessing over the details of a web experience; others you're the one unblocking a whole team by shipping something they didn't even know was possible., * Own the full marketing site stack - from frontend and CMS to backend services, analytics, and deployment. You're not just a contributor here; this is yours to build and evolve.

• Lead development on customer-facing products and commerce tools, working closely with our Customer Experience and Product Design teams to deliver experiences that convert and delight.
• Partner with Design, Marketing, and Publishing to ship content experiences that drive customer acquisition - and run experiments that turn data into smarter decisions.
• Build and maintain integrations with third-party APIs and external services that keep our internal teams productive and our stack humming.
• Obsess over performance and user experience - from Core Web Vitals to CMS workflows - so that every interaction feels fast, polished, and intentional.
• Develop and maintain our Web Design System and component libraries, keeping the foundation consistent and scalable as the product and team grow.

Do you have experience in UI design systems?, * You have strong, production-proven experience in **TypeScript, React, and Next.js (**or similar e.g. SvelteKit) - and you're proud of what you've built or worked on. We'd love to hear about it.

• You're comfortable across the full stack - from CMS platforms like Sanity or Contentful to APIs, backend services, and analytics integrations.
• You care about reliability and observability - you write tests, set up monitoring, and don't consider something truly shipped until you're confident it won't fall over in production.
• You own your work end-to-end - from scoping and building to deployment and smoke testing in production. Done means done.
• You've worked closely with non-engineering teams before - marketers, designers, stakeholders - and you know how to translate between creative vision and technical reality.
• You embrace AI-assisted tools like Claude Code - and you know when to trust them and when to push back., * You have a DIY mindset and genuine obsession with code quality, user experience, and craft - always asking how things could be better, and doing something about it.
• You thrive in a high-agency environment where you're trusted to move fast, make calls, and raise the bar on how the team works - not just what it ships.
• You've worked directly with stakeholders - leadership, marketing, design - and understand that your job isn't just to write code, but to unblock people and move the needle on outcomes that matter., * Have experience with international localization architecture (e.g. Lokalise or Crowdin) - big plus given where we're headed.
• Have implemented privacy compliance (e.g. GDPR) and managed cookie consent flows.
• Have maintained software libraries or written technical documentation others actually want to read.
• Love staying active and believe in what we're building

Pulled from the full job description

• Flexible schedule, * Competitive compensation package.
• Flexible working hours and vacation policy.
• Product-driven culture that treasures talents and individual growth.
