About Optiml

Optiml is revolutionizing real estate with our Real Estate Decision Intelligence (REDI) software—a new class of decision technology that embeds AI to help decarbonize buildings while optimizing asset financial performance.

We are an ETH Zurich spin-off that launched its first product in April 2024 and has since been scaling across Europe and the United States, earning major industry recognition, including the 2024 ULI Europe Prop Tech of the Year and 2024 ZIA Prop Tech of the Year awards.

We are backed by top-tier US and European investors, including Innovation Endeavors (the fund of former Google CEO Eric Schmidt), Planet A, Bit Stone, and Kompas, who support our mission to empower real estate investors, asset managers, and consulting partners to deliver a cost-effective, value-preserving transition to Net Zero.

As of early 2026, we are expanding our team to broaden our product lines and scale operational delivery for a growing global client base.

As a Junior Frontend Developer, you will:

• Build and maintain user-facing features using React and Type Script
• Help turn UI/UX designs into responsive, performant interfaces
• Work with teammates to integrate backend APIs
• Participate in the full development lifecycle: planning, coding, testing, and iteration
