The Role
Join as the founding engineer to own architecture and ship features for an AI-driven adaptive learning platform. Build full-stack (Next.js/TypeScript/Python), implement LLM agents and RAG pipelines, iterate with schools, and shape technical strategy and hiring as an equity-holding co-founder.
Summary Generated by Built In
Sokra is building an AI-powered adaptive learning platform that's already being tested by 50+ schools across Germany. Major publishers are reaching out, and we're preparing our angel round. We're a team of 3 founders (EXIST-backed, HU Berlin) looking for our first engineer — not an employee, but a co-builder with real ownership.
Tasks
* Own and shape the entire technical product alongside the founding team — from architecture decisions to shipping features
* Build and iterate on our AI-powered learning engine (LLM agents, RAG pipelines, adaptive content delivery)
* Develop the full-stack platform (Next.js, TypeScript, Python, WebSockets)
* Work directly with schools and teachers to turn feedback into product improvements
* Contribute to technical strategy, hiring decisions, and company direction as a founding team member
Requirements
* Strong full-stack experience with TypeScript/React/Next.js and Python
* Hands-on experience or deep interest in AI/ML, LLMs, and RAG architectures
* 0→1 builder mindset — you've shipped products, not just features
* Degree in Computer Science or related field (graduated within the last ~5 years)
* Based in Germany or willing to relocate to Berlin (hybrid setup)
* Fluent in English; German is a plus but not required
Benefits
* 0.5–2% equity with 4-year vesting — real ownership, not a token gesture
* Be founding engineer #1: shape the product, the culture, and the technical direction
* Mission-driven work: AI that actually helps students learn, not another ad-tech tool
* EXIST-funded runway (~12 months) + angel round in preparation
* Hybrid work from Berlin, flexible hours
* Direct impact: your code is used by real teachers and students every day
This isn't a "join our growing team" role. We're 3 founders looking for a 4th brain. If you want to build something meaningful from scratch and have real skin in the game, we'd love to hear from you. Apply now — we'll get back to you within 3 days. First step is a casual 20-minute call.
