PstrongAbout You /strong /p pAs a Software Engineer (Infra Focus), you will own the infrastructure backbone that keeps Optiml's platform fast, reliable, and ready to scale—operating at the intersection of backend engineering and cloud infrastructure, where your decisions directly shape how the product is built and shipped. /p pThis is a hands-on engineering role: you will manage and evolve Optiml's GCP infrastructure, drive CI/CD and release processes end-to-end, and contribute directly to the codebase on core systems like RBAC and job queues. You are as comfortable in a Python codebase as you are configuring IAM policies or leading an incident response. /p pYou are expected to be proactive and opinionated—identifying infrastructure debt before it becomes a problem, setting a pragmatic direction for the platform, and executing without waiting to be asked. You bring reliability and composure to production systems, and the clarity and communication skills to bring the rest of the team with you. /p pstrongAbout Optiml /strong /p pOptiml is transforming real estate with Real Estate Decision Intelligence (REDI), an AI-powered decision technology that helps decarbonize buildings while optimizing asset and portfolio financial performance. /p pOur platform helps investors, owners, and asset managers make clearer capital allocation and decarbonisation decisions by translating complex regulatory, financial, and technical constraints into actionable renovation and investment plans. /p pFounded as an ETH Zurich spin-off, Optiml launched its first product in April 2024 and is now scaling across Europe and the US, with teams based in Zurich, London, and across Germany. The company is backed by leading US and European investors, including Innovation Endeavors (the fund of former Google CEO Eric Schmidt), Planet A Ventures, KOMPAS, BitStone Capital, and The Bau Ventures.
