About You The Building Engineering Lead will be Optiml's senior Subject Matter Expert (SME) for building engineering, responsible for how buildings, systems, and costs are represented, structured and reasoned about across Optiml's products and deliveries. You will define the engineering logic, assumptions, and accuracy levels that underpin Optiml's product tiers. Ensuring our strategies are technically credible, scalable across geographies, and defensible with enterprise clients. Our ambition is to handle any building typology, up to complex, large-scale assets, with appropriate and transparent accuracy. Working across Product, Delivery, and Engineering, you will translate real-world building engineering practice - including MEP/HVAC systems, digital twins, building physics, Capex structures, norms, and typologies - into clear frameworks that guide product development, client delivery, and long-term roadmap decisions. 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.
