(Junior) Full-Stack Engineer (gn)

sofatutor is a digital learning platform for nearly 2 million early learners, students, parents, and teachers. As a (Junior) Full-Stack Engineer (gn) in Team Growth, you ship features on the visitor-facing pages where new users first meet us. You build; our Growth Specialists deliver the testing ideas and hypotheses.

📍Remote (EMEA) | ⏳ 40h/week

Your Tasks:

As (Junior) Full-Stack Engineer (gn) you will:

• Build and release features on visitor-facing pages and conversion funnels.

• Implement A/B tests cleanly and reliably, based on hypotheses handed over by our Growth Specialists.

• Use AI tools daily – prompt, steer, validate – and review AI-generated code with the same care as your own.

• Write and maintain unit and integration tests (Capybara, Cypress). Testing matters more, not less, when code is co-produced with AI.

• Own critical systems in the visitor journey: maintenance, reliability, and incident response.

• 2–3 years of hands-on engineering experience in web development – enough to ship production-ready code independently from day one.

• comfortable across the stack (HAML, CSS, JavaScript, Ruby).

• Strong eye for code review and QA → you spot what's off, whether it's your code or AI's.

• You actively use AI in your daily work and have real opinions: where it helps, where it fails, and how to review output before it ships.

• Pragmatic – excited by focused, high-impact work on a clean stack, not by the newest framework or the most complex architectural puzzle.

• Very good written and spoken English
