Fullstack Engineer

About FunnelFox

FunnelFox is a no-code platform that helps app developers grow revenue through web2app funnels. Launched two years ago, it’s already showing impressive growth. Marketers and product managers can build, launch, and optimize funnels in hours instead of months, all without writing a single line of code.

About the team

Funnels team owns the FunnelFox funnel builder, the product where it all started and the first thing our clients touch. Right now the team’s top priority is bringing AI into the builder: an AI agent, MCP, and AI-powered funnel generation. The goal is to give clients the fastest possible way from an idea to a live funnel.

Why we’re hiring

We’re looking for a Fullstack Engineer to own features of the builder end to end, not just to implement tickets.

You’ll combine engineering skills, product thinking, and close collaboration with the business to ship AI-powered features that clients feel right away. Our roadmap is moving toward deeper MCP integration and an AI agent that works like a growth manager: it understands what the client wants, asks clarifying questions, and builds the result for them. You’ll get your own area of responsibility and the autonomy to drive it.

What you’ll do

• Own the delivery of builder features end to end, from the first conversation with Product to checking how they work for real clients.

• Build AI-powered functionality: the AI agent, MCP, and AI-based funnel generation.

• Work across frontend and backend (roughly 50/50, sometimes leaning toward frontend) and build integrations.

• Partner closely with Product to clarify business expectations, discuss edge cases, and shape solutions.

• Take ownership of your own area of the product and be the go-to person for it.

• Take responsibility for the quality of what you ship, together with the QA team.

• Share progress through milestones, decompose complex tasks, and raise questions early so nothing gets stuck.

You’ll be a great fit if you have

• Solid professional experience in fullstack development.

• Experience with a modern frontend framework (we use Svelte, but any framework works) and a backend language (we use Go, which is quick to pick up).

• Experience owning features from clarifying requirements to production.

• Experience in product teams or startups, with a focus on speed and direct communication with the business.

• Practical experience using AI tools in your daily work (experience with agents or MCP is a big plus).

• Experience with databases and working with data.

• Product and business orientation: you think about user impact, not just code correctness.

• Autonomous, proactive working style, clear written communication, and the ability to learn fast.

What you may expect from working with us:

• Flexible remote work: Work from anywhere with a schedule that fits your life. Our core team operates in Europe, and we welcome candidates worldwide using Deel.com.

• High ownership and real impact: You’ll actively influence product and technical decisions, not just execute predefined tasks.

• Fast-moving startup environment: We value speed, autonomy, and practical problem-solving over rigid corporate processes.

• Direct communication: We keep things simple and transparent, ensuring you focus on what matters most — getting things done.

• Professional Support: We provide a monthly budget that you can allocate based on your personal and professional priorities — including language learning, professional development, mental health support, sports, or health insurance.
