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 PropTech of the Year and 2024 ZIA PropTech 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, BitStone, 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 TypeScript


• 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


• Collaborate on code reviews, architecture discussions, and product improvements

This is an on-site role in our Zurich office — ideal if you enjoy working closely with a small, dynamic team.

• Has 3+ years of professional experience or is a recent graduate in Computer Science, Software Engineering, or a similar field


• Can write clean JavaScript/TypeScript and has practical experience with React (projects, internships, coursework, or early career)


• Understands the basics of component architecture, state management, and responsive design


• Is eager to learn — you build things, ask questions, and take ownership of your growth


• Communicates clearly in English and collaborates well with others


• Can work physically from our Zurich office

Nice to Have (Not Required)

• Interest in UI/UX design principles


• Exposure to backend APIs (REST/GraphQL)
