SimScale is revolutionizing the engineering world by empowering engineers everywhere to innovate faster and explore thousands of engineering decisions in seconds. We are the pioneers of cloud-native simulation, now leading the shift toward Engineering AI and Physics AI .

We are a fast-growing SaaS scaleup with international presence, serving thousands of engineers globally. To support our ambitious mission, we are backed by Insight Partners, Union Square Ventures, Earlybird, and other strong European and US investors.

Your Opportunity

We are looking for a highly experienced Interim CFO to join us part-time, with the strong potential and mutual interest to evolve into a full-time executive role. Partnering directly with the executive team, you will act as the financial architect of our next growth phase, designing a scalable engine that supports long-term strategy and future strategic milestones.

This is a role for a leader who enjoys the intellectual challenge of building the machine , not just driving it. You will ensure our financial infrastructure is as robust, innovative, and scalable as our AI-driven software.

Your Responsibilities

• Strategic Fundraising & Corporate Development: Prepare SimScale for future financing events (Growth Equity, PE, M&A). You will ensure our data rooms, equity story, and reporting standards are "due diligence ready" at all times, maximizing our strategic optionality.
• Advanced Forecasting & Scenario Planning: Move beyond static budgeting. Build dynamic "what-if" scenarios (Base/Bull/Bear) that allow the Board to stress-test strategies live, balancing aggressive investment in product innovation (e.g., Physics AI) with capital efficiency.
• Enterprise Sales Finance Partner: Act as a strategic deal-architect for our sales organization (our primary engine). You will model the economics of complex Enterprise agreements , ensuring we optimize cash flow, Net Retention Rate (NRR) , and long-term customer value.
• Architecting the Financial OS: Drive the transformation from legacy models to a robust, automated Financial Operating System . You will build the data infrastructure that provides the leadership team with real-time, actionable insights.
• Financial Stewardship & Trans-Atlantic Compliance: Oversee our international operations (DE/US), ensuring precise Cashflow and Balance Sheet forecasting while navigating the complexities of German/US GAAP and tax regulations.

Your Profile

• You Operate at Two Speeds: You are a strategic executive who can command the room with investors in the morning, and a hands-on architect who can dive deep into the revenue model in the afternoon. You know the numbers better than anyone because you understand how they are built.
• You have "Major League" Experience: You have successfully navigated the late-stage scaleup journey before. You bring hands-on working experience with fundraising and leading financial due diligence with top-tier VCs.
• You are a Builder, Not Just an Overseer: You don't just delegate; you possess deep analytical rigor . You enjoy architecting complex financial models from first principles to ensure they reflect the true logic of the business.
• You understand our Business Model: You possess a deep understanding of B2B SaaS metrics ( Rule of 40, Magic Number, CAC Payback, etc. ). You instinctively understand the financial friction between high-velocity inbound sales and complex enterprise cycles.
• You have Strategic Weight: Experience preparing organizations for public markets or strategic M&A is a strong plus, ensuring our financial rigor meets the highest international standards.
• You are a Compliance Expert: You have deep, practical experience bridging the gap between German GAAP requirements and US SaaS reporting standards.

What you can expect from us

• Impact: The chance to shape the financial backbone of a company that is defining the future of Engineering AI.
• Flexibility: A strategic engagement structure that respects your time, with a clear, pre-defined path to a permanent C-Level role.
• Culture: An international, enthusiastic team that values dedication, technical expertise, and an independent working style.
• Growth: An environment where ambitious tasks leave space for creativity and professional development.
