## Job description

**Build the Interface of the Energy Transition**

Most engineering jobs ask you to ship fast and care about quality.
This one asks you to **build the interface of an entire industry.**

At Reonic, we’re building the AI operating system for renewable installers, with competitive pay, growth opportunities and a strong culture based on ambition, impact and ownership.
And we’re doing it **fast**.

**What makes this role 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.

Just **building, shipping, improving**.

**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 — **no layers, 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 project

This is not a narrow role. 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

If you need perfect specs and slow timelines — this isn’t it.
If you want to **grow fast and ship real product** — you’ll love it.

**Why join now**

- Competitive pay and equity opportunities
- High ownership from day one and unlimited growth options
- Steep career development: No cycles — rewarded when earned
- Gym membership or Transportation ticket: pick between Urban sports club or D-ticket
- Uber eats and Uber drive on us when you finish late
- Take a few "workation" weeks a year—work remotely from anywhere.
- We're still early. Be at the forefront of the energy transition.

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

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.
