  • Collaborate closely with product managers, R&D, security, UX & design, content, product marketing, customer support, and marketing teams.
  • Drive continuous improvement by devising, executing, and measuring A/B tests on our user-acquisition flows, directly impacting our core KPIs.
  • Stay hands-on by actively contributing code, conducting design reviews, and working side-by-side with your team to tackle technical challenges.

Sounds great Am I the right fit?

Well, our guess is you have a good chance of being that person if you check as many of these as possible:

  • 2+ years of team lead experience and 5+ years in fullstack development, taking projects from initial commit to production.
  • Expert in building scalable systems with React, React Native (TypeScript) on the frontend and Python on the backend.
  • Proficient with cloud platforms and tools like GCP, GKE, MySQL, Redis, and BigQuery.
  • Proven track record of leading projects from concept to full production.
  • Experience with web analytics—defining user journeys, and setting up and evaluating A/B tests.
  • Understands product marketing and user acquisition, turning marketing goals into technical solutions.
  • A collaborative, fast, self-motivated learner with excellent communication skills, committed to delivering secure, high-quality solutions.

Talk nerdy to me.

  • React + React Native (using TypeScript)
  • Python
  • GoogleCloud using K8S
  • MySQL + Redis + BigQuery
  • Thinking of a great addition? Let's do it.
