Software Engineer Intern - (AI x Greentech) (m/f/d)

Most internships ask you to watch, learn, and maybe fix a few bugs. This one asks you to help build the interface of an entire industry. At Reonic, we’re building the AI operating system for renewable installers, with a strong culture based on ambition, impact, and ownership. And we’re doing it fast. What makes this internship different • Your work directly impacts how renewable energy gets deployed • You’ll own features end-to-end, not just tickets • You’ll feel the speed: idea → code → live → feedback • No endless planning cycles. No hiding behind process. No side projects nobody uses. Just building, shipping, improving, with real responsibility from week one. Please note: This is a fully onsite internship in Augsburg for 4–6 months. You will: • Build high-impact features used daily by real businesses • Ship fast using TypeScript throughout the whole stack • Dive into Node.js backends and handle data with PostgreSQL and Prisma • Turn complex workflows into clean, intuitive interfaces with React and Tailwind • Work closely with product and design, with no layers and no handoffs • See your code in production within days, not months And if you want more: Work with Rust to extend our simulation that predicts the future of our customers’ projects. This is not a narrow internship. It’s a playground for builders. You’ll thrive here if you… • Love turning complexity into simplicity • Care about UX as much as clean code • Prefer ownership over instructions • Move fast, learn fast, and fix things instead of debating them • Actually want to build , not just talk about building • Have already built things, whether through side projects, hackathons, open source, working student jobs, or previous internships. Experience with TypeScript and React is a plus. • Are currently enrolled at a university and available full-time for 4–6 months. If you need perfect specs and slow timelines, this isn’t it. If you want to learn fast and ship real product , you’ll love it. Why join now • A competitive internship salary • High ownership from day one: you’ll work on real features, not a sandbox • Learn from a strong engineering team that gives you direct feedback • Gym membership or transportation ticket: pick between Urban Sports Club or D-Ticket • Uber Eats and Uber rides on us when you finish late • We’re still early.
