Senior Fullstack Engineer
Build the core product - from the funnel builder engine to the analytics dashboard. TypeScript, Svelte, and distributed systems.
Build with ownership at Funneled.
Join a small, profitable team building the fastest way for performance marketers to launch, test, and scale high-converting funnel experiences.
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
