Strategic Finance Operator

The Company In 2019, we started building profitable startups from scratch. We brought together top minds to drive the highest success rate in the industry and turn company building into a science. During that time, we’ve built ten high-growth companies, driving $200M+ in revenue. Along the way, we’ve developed an engineering approach to entrepreneurship rooted in algorithms and data. Now, we’re working to automate company building to a point that we can press a button to launch profitable companies, ventures that can reinvest their own resources to become enterprises that help millions, or even billions, of people. Position Description The Strategic Finance Operator is the financial thought partner that Mechanism’s portfolio CEOs, Heads of Growth, and executive leadership rely on. You are not a reporting function, a back-office hire, or confined to one company or one domain. You are embedded across a number of high-growth companies and Mechanism Ventures itself, advising operators on the decisions that matter, owning the financial narrative that everyone trusts. This is a high, but intentional bar. Mechanism Finance is being rebuilt. We made real progress: commodity accounting is outsourced, reporting infrastructure is being automated, and the systems that used to consume a finance team’s time are increasingly handled systematically, but we are not done. What lands on this role today will be unglamorous: edge cases that don’t fit any workflow yet, requests with no clear owner, financial questions that technically belong somewhere else but practically land here because you’re the person with context. The right person for this role is not deterred by that. They are motivated to close the gap, because building the systems that eliminate that work is part of the job, not a distraction from it. This role requires generalist financial acumen, driver-based instincts, multi-company fluency, and the breadth to operate independently at the highest level of the finance function. What You’ll Do Advise operators on their most consequential financial decisions You sit with CEOs on unit economics, cash flow, runway, and growth investment. You ask questions they have not thought to ask. You pressure-test assumptions before they become commitments. You are the person they call when they need to think, not just when they need a number. Own the financial narrative Understand and communicate actuals against plan at a driver level. You do not build forecasts that can only be interrogated by another finance person. Provide forward-looking commentary grounded in what the business is actually doing with intellectual honesty over optimism. Provide deliverables that can be acted upon, not just read. Validate the analytical layer Work alongside the Finance Operator, Data to define what gets built and confirm it is financially correct before it reaches anyone. You have the acumen to know when an output does not make sense and the credibility to say so. Handle the full financial surface area For any given company, there are valuations, tax considerations, SPV distributions, inter-company billing, and funding proposals. This is not a narrow role. You will encounter the full range of financial questions that arise across a growing portfolio, and be expected to navigate them with genuine competence, not just escalate them. A finance person first You can read a P&L, understand unit economics, and know when a number is wrong. This isn’t because someone told you, but because you understand how businesses work. The technical work, the advisory work, the accounting work all sit on top of this foundation. Built for a multi-company environment You hold financial context across multiple businesses simultaneously without confusing them. You find it interesting that one company has a seasonality problem while another has a CAC problem, rather than wishing you could just focus on one thing. No passengers You get better fast. You build systems rather than just doing the work. You leave functions better than when you found them. You do not wait to be told what needs fixing. What you’ll bring You have 6-10 years of FP&A, startup finance, or multi-company work. You have advised founders or operators directly. Driver-based modelling is your default. You are comfortable holding financial context across multiple companies simultaneously. You learn fast, build systems rather than just doing the work. You have worked across a portfolio, PE-backed roll-up, or multi-entity environment. You have built financial reporting infrastructure from scratch, not just inherited it. You have enough accounting literacy to QA a close without running it yourself. You have experience with modern FP&A platforms. This is not the right role if You prefer a defined lane and predictable scope. You need all the information before making a decision. You think a polished output is the same as a verified one. You have only ever served one company at a time and struggled with context-switching. You are looking for a mature, fully systematized finance function to step into. Time Commitment This role is full-time and will need to overlap with US ET for the majority of the workday. It is an exciting opportunity that demands a level of dedication beyond the standard 9 to 5. We need someone who's willing to go above and beyond to help us achieve our ambitious goals, and who's eager to put in the effort to make a real impact. Location US-Based - Fully remote.
