Full-Stack Software Engineer

About You

As a Fullstack Engineer at Optiml, you will play a key role in shaping and scaling our core product. You’ll work across frontend and backend systems to build elegant, high-impact solutions that solve real customer problems and bring our data and models to life.

Your mission is to own meaningful parts of the product end to end: from early concept and prototyping through to production-ready implementation. You’ll collaborate closely with product, design, and engineering peers to define architecture, ship quickly, and continuously refine the user experience.

This role blends strong product intuition with hands-on execution. You’ll be trusted to make smart trade-offs, move fast, and take ownership of the full development lifecycle. While maintaining a high bar for quality, usability, and performance.

We’re looking for a driven fullstack engineer who thrives in a fast-paced environment, pushes for impact, and brings curiosity, kindness, and energy to the team. If you’re motivated by building beautiful, scalable products and want to help define Optiml’s technical foundation, this role offers a chance to make a meaningful mark.

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 our first product in April 2024 and are now scaling across Europe and the US. We recently raised an oversubscribed €8M Seed round to accelerate our growth, supported by leading VCs such as KOMPAS, Planet A Ventures, Innovation Endeavors (the fund of former Google CEO Eric Schmidt), BitStone Capital, and The Bau Ventures, along with leading angels.

Built on more than a decade of research and proprietary IP, our platform enables institutional investors, owners, and asset managers to make underwritable, forward-looking decisions across the full asset lifecycle — from acquisition to exit — replacing static, backward-looking reports with actionable intelligence.

Trusted by leading organizations across Europe and beyond, Optiml supports capital allocation decisions that balance key financial, regulatory, and sustainable considerations under real-world constraints.

As of early 2026, we are expanding our team to scale our product capabilities and operational delivery as we work to make Real Estate Decision Intelligence the global standard for real estate investment decision-making.
