Full-Stack Software Engineer (m/f/d) Berlin, Germany

Job description

About Us We believe every child deserves the chance to reach their full potential — and that strong foundations in literacy and numeracy are where this begins. EIDU partners with governments to strengthen public education systems at scale. Our technology-enabled platform integrates proven educational interventions and supports learners, teachers, and ministry staff within national systems. Today, we work with 41 governments and will reach 1,000,000 active students across Kenya and Nigeria in 2026. We have doubled our learner numbers each year over the last five years and aim to reach tens of millions more. A randomised controlled trial found a 0.53 standard deviation improvement in learning outcomes — placing EIDU among the top 10% of education interventions in low- and middle-income countries. EIDU is funded by governments, leading development agencies, and foundations. We are building an organisation capable of turning strategy into measurable impact at national scale. About the role We're looking for a mid-level or senior Full-Stack Software Engineer to help us build the next generation of our platform — a highly configurable, modular system used by governments and education organisations across Africa and beyond. What you will do: Ship product features end-to-end: plan, analyse, document, code, review, test, and release high-quality code across the full stack — both frontend and backend, Build our core platform: the configurable system that lets hundreds of organisations deploy and adapt our product — backed by the services, APIs, and data infrastructure that keep it running. Design and build modular, web-based frontend components — widgets and plugin-like building blocks that slot into that platform and reach millions of students. Keep quality high by writing readable, maintainable code, adding meaningful tests, monitoring in production, and driving complex issues to resolution. Apply your experience with enterprise-scale systems to make thoughtful architectural decisions: code that performs for millions of users across varied environments is very different from code that works for one. Share what you learn by pairing with teammates, contributing clear docs, and raising the bar through thoughtful reviews and feedback. Champion AI tools in our workflows — not just as a user, but as someone who actively finds new ways to apply them: LLM-augmented coding, debugging, documentation, or building AI-enhanced internal tooling. We're a small team with a big mission — which means efficiency and leverage matter immensely. You'll use the right tools, automation, and AI to multiply our impact. What you should bring: The desire to use your skills to bring about positive social change. Demonstrated experience as a mid-to-senior engineer; you've built production systems at scale in established organisations. Experience building software used by many organisations simultaneously: configurable, multi-tenant, or platform-style systems where your decisions affect how hundreds of customers experience the product. A solid foundation in web technologies (React, TypeScript) and experience building modular, composable frontend components. Exposure to low-code or no-code platforms: whether you've built one, contributed to one, or used them deeply enough to understand what makes them powerful and where they fall short. A passion for writing clean, maintainable, and testable code. A genuine enthusiasm for AI tools. You actively experiment with them, find new applications, and help the people around you do the same. Excellent collaboration skills and a willingness to learn new tech or dive into unfamiliar systems. We speak and operate in English. Knowledge of German is not required. What we offer: Work on one of the biggest problems in the world: ensuring every child gets the education they deserve. A small, high-impact team of about a dozen engineers where your work shapes the product direction. An open environment where feedback is welcomed, promoting mutual growth. A modern, evolving stack: Backend: AWS, Kotlin, Kubernetes, Kafka, MongoDB, microservices Frontend: React, TypeScript, Android, Kotlin, Jetpack Compose Two creative hackathon weeks per year, where you can explore bold new directions. Transparent and fair salary bands — we believe everyone should be paid equitably, without needing to negotiate. Competitive equity-awarding model and a highly flexible working hours, vacation time, and work from home policies. If you're passionate about making a meaningful difference in global education, we'd love to hear from you.
