Quick summary: We are looking for a Webflow Engineer to join our Marketing team. Today, we rely on a mix of internal contributors for Webflow builds, tracking, and checkout flows. We’ve decided it’s time to bring in a dedicated in-house engineer who can own this area end-to-end. From landing pages and conversion funnels to experiments, performance, and backend integrations. Instead of building core product features, you’ll build and ship marketing-facing code: Webflow sites, custom components, tracking infrastructure, and backend services that power dynamic content, forms, and automation-ready pages.
You will be the person who ensures that every prospective user sees a fast, intuitive, and clearly communicated version of Sintra.
Why join Sintra?
We build AI employees for small businesses. Real helpers with personalities, not faceless chatbots. They handle the work that keeps owners up at night - answering customer emails, posting on social media, analyzing sales data. For business owners who've always worked alone, we're giving them their first team. 50,000+ businesses use Sintra because for the first time someone made AI actually useful for them. While Silicon Valley builds for tech companies, we're building for the florist who needs help with Instagram, the contractor drowning in invoices, the restaurant owner who can't keep up with reviews. This is a unique moment in history. AI just became good enough to fundamentally change how small businesses operate. Behind every business is someone trying hard for their family. Someone with one goal - put food on the table. And our job is to help them succeed. Having just raised our $17M seed round, we're off to the races. Small, fast-moving team building together in person. We ship daily, take ownership of what we build, and live by one principle - work is play.
Who we're looking for
- 4+ years building production-quality web experiences
- Deep expertise in Webflow, including complex CMS and high-performance page builds
- Strong React / Next.js skills for extending Webflow with custom components
- Solid backend experience (Python or Node.js) for lightweight APIs and integrations
- Strong product and growth intuition - you understand how technical choices impact conversion
- Comfortable owning the entire marketing web stack end-to-end
- Proven ability to ship independently while collaborating closely with design, marketing, and engineering
- High attention to quality - you catch issues early and maintain clean, reliable systems
- Comfortable using AI tools to accelerate development and experimentation
What you'll do
- Build and maintain our Webflow-based marketing presence - landing pages, funnels, checkout flows, and campaigns
- Extend Webflow with React/Next.js components and lightweight backend services in Python or Node.js when needed

- Run experiments - A/B tests, funnel optimizations, and performance improvements - to drive continuous growth
- Work closely with designers and marketers to translate ideas into fast, high-quality web experiences
- Own the full marketing web stack end-to-end: architecture, performance, reliability, and delivery
- Ship quickly, iterate often, and make decisions based on data and user behavior
