Employment Type: Permanent employee

Schedule: Full-time

Make the "black box" of AI optimization visible and actionable. You build the interface that allows facility managers and EMS integrators to trust and control our optimization engine.

From powerful configuration modules to intuitive mobile experiences, you make interactions with our complex optimization engine feel simple and enjoyable.

Key responsibilities

• Core Product UI: Architect and build our main web application using modern technologies (e.g., React, TypeScript). 
• User-Facing Product: Create and improve key desktop experiences like dashboards and digital twin configurations as well as intuitive on-site mobile experiences like e-vehicle charging and maintenance scheduling.
• Advanced Data Visualization: Implement high-performance charting (D3.js, Recharts, etc.) to display live power flows and optimization schedules without clutter.
• UX/UI Ownership: You bridge the gap between "functional" and "delightful." You turn complex requirements into intuitive user flows.
• Component Architecture: Establish a reusable component library that scales across different views (mobile vs. desktop) and ensures UI consistency.
• Own Delivery End-to-End: Work onsite-first in a cross-functional team. You define the frontend standards and see features through to production.

• 5+ years of experience building rich SPAs and responsive web applications.
• Deep expertise in TypeScript and a modern framework (React, Vue, or Svelte).
• You understand that Mobile First isn't just a buzzword but that it is about touch targets, layout shifts, and simplifying flows for users on the go.
• You know how to leverage AI tooling effectively, speeding up exploration and prototyping while keeping the production codebase robust, clean, and maintainable.
• Clean, maintainable code matters to you, and you’re always looking for ways to improve how things get built.
• You think like an owner, not just an executor: proactive, curious, and hands-on.
• Pragmatic design sense: You can take a rough concept and turn it into a prototype, then iterate until it is a polished, user-friendly interface.
• Bonus: Experience with Data Visualization libraries or the Energy Domain.

• The excitement of working in a driven start-up team, where your contribution truly matters.
• Competitive salary with additional benefits such as EGYM Wellpass
• Make a difference by accelerating the energy transition with your work.
• Prime location: Office right at Goetheplatz in Munich (home office days possible)
• Keep growing as you help define the future of energy software, moving fast, solving tough frontend problems, and building alongside a collaborative team.
