Tech Lead (Billing Team)

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

Billing team owns one of FunnelFox's most strategic products. Billing is a core part of our payments ecosystem and a key driver of the company's growth. The product has already reached product-market fit and is now entering the next stage: scaling the platform, expanding functionality, and building the best billing solution for the Web2App market.

Why we're hiring

We're looking for a Tech Lead to own Billing as a product, not just as a codebase.

You'll combine technical leadership, product thinking, and business ownership to help shape the roadmap, make architecture decisions, improve reliability, and build features that directly impact customer value and company revenue. As the team grows, you'll also help scale the engineering setup around the product.

What you'll do

• Own the technical execution and evolution of Billing.

• Partner closely with Product and business stakeholders to shape solutions, priorities, and roadmap.

• Drive architecture, scalability, reliability, and observability across the platform.

• Build and ship features that improve customer value and business growth.

• Lead incident investigation and continuously improve operational excellence.

• Mentor engineers while remaining hands-on.

• Help grow and scale the team as the product enters its next stage.

You'll be a great fit if you have

• 7+ years of Python as your primary language, actively used now.

• Solid experience with payment systems or billing infrastructure at scale (systems processing $50M+ per year).

• PostgreSQL experience.

• Docker and Kubernetes basics (you don't own infra, but you need to understand how it works).

• Hands-on experience with monitoring, alerting, observability.

• Ability to handle both feature development and operational complexity.

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

• Autonomous working style.

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: Engineers actively influence product and technical decisions, not just implementation details.

• 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.
