About this job

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.

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. Be at the forefront of the energy transition.

At Reonic, we’re building the AI-native operating system for renewable installers.

We’re replacing fragmented tools (CRM, design, proposals, project management, invoicing) with a single integrated platform that supports installers across the full project lifecycle. Today, more than 3,000 companies across 13 countries use Reonic, and it’s just the beginning.

We’re a well-funded, VC-backed startup reshaping how the world uses energy, with top-tier people, great investors, and massive goals ahead. We work hard and move fast to build a company that lasts and that brings lasting change.

This is a full-time, on-site internship based in Augsburg for 4–6 months.
