Senior Fullstack Engineer

About the role

You’ll build Funneled’s core product end-to-end. The drag-and-drop funnel builder. The real-time analytics dashboard that gives users visibility into their conversion metrics. The SDK that developers use to embed and customize funnels. This is the kind of role where you ship a backend feature in the morning and polish the UI for it in the afternoon.

We’re a small team, so you’ll have direct impact on architecture decisions and product direction. No tickets assigned from above - you’ll help decide what to build next.

What you’ll do

• Build and extend the funnel builder engine (template system, drag-and-drop, live preview)
• Ship features across the full stack - API, UI, and SDK
• Design data models and APIs that scale with product complexity
• Work directly with users to understand pain points and iterate quickly
• Improve developer experience for both our users and our team

What we’re looking for

• Strong TypeScript skills across frontend and backend
• Experience building real-time, event-driven systems
• Comfort working across the stack without waiting for handoffs
• Good instincts for API design and data modeling
• You’ve shipped products, not just features

Nice to have

• Experience with Svelte/SvelteKit
• Background in marketing tools or conversion-focused products
• Familiarity with funnel builders, landing page tools, or marketing tech
• Experience at early-stage startups
