Senior full stack engineer, User onboarding

3 – 5 years · $5K to $6K USD · Copenhagen, Denmark · On-site · Relocation support

Role overview

We are looking for a senior full stack engineer to own the user onboarding journey end to end — from the first signup screen to a fully activated account. You will work across a modern TypeScript stack, shape experiment roadmaps with designers, and ship improvements weekly.

This is a high-leverage role: onboarding conversion is the company’s north-star metric, and your work will be seen by every new customer. You will mentor two mid-level engineers and partner directly with product and data.

What you will do

  • Own onboarding flows across web and API, from signup to activation
  • Build and maintain features in TypeScript, Node.js and React
  • Design and run A/B experiments that lift trial-to-paid conversion
  • Partner with designers on prototypes, UX copy and empty states
  • Mentor engineers through reviews, pairing and clear technical writing

What you bring

  • 3–5 years building production web applications
  • Deep TypeScript fluency across frontend and backend
  • Experience with experiment-driven product development
  • Strong SQL and familiarity with event analytics
  • Clear written communication; EU work eligibility or relocation readiness
