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.

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:

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.
