Full Job Description
About the role
As Lassie's first finance hire, you'll build out the company's financial operations from the ground up. You'll work alongside CEO Steijn Pelle and Lassie advisor Jason Warnick (former CFO, Robinhood). You'll own the transition from founder-led finance to a world-class, AI-native function. This is a unique opportunity to build the systems that shape how Lassie grows and operates.
This role is as strategic as it is operational. You'll be involved in every major financial decision, from daily tradeoffs to strategic finance projects, and you'll be the person who gives the leadership team confidence in where the company stands and where it's headed financially.
What you'll do
Establish and own the reporting of the company's key metrics (think active practices, ACV, ARR, net dollar retention, churn, payback period) so you can measure progress
Build and maintain the company's financial operating model, including scenario planning and tradeoff visibility, so leadership can make confident resource and growth decisions
Ensure an accurate, timely monthly close and deliver financial statements that give leadership an actionable view of the business
Own the full FP&A cycle: budget, quarterly actuals, monthly reporting
Serve as the CEO's key finance partner through future fundraises
Build scalable, AI-native finance infrastructure across accounting, forecasting, spend management, and payroll, choosing tools that reduce complexity and grow with the company without overbuilding
Lead strategic finance work beyond the core: pricing structure, sales commission design, rev ops foundations, and more
What we're looking for
Must-have
You've built operating models, scenario plans, and unit economics from scratch in a startup environment, and you can defend your assumptions with board-level rigor
You're a hands-on operator: you've closed the books, managed vendors, and run payroll, not just managed people who do those things
You translate complex financial data into clear insights for a non-finance audience and are comfortable presenting to founders, board members, and investors
You have a track record of implementing finance systems and building processes from scratch. You know when the current tool is right-sized and when it's time to graduate, and you don't over-engineer
You've designed or built AI-native workflows for finance tasks, or have a strong instinct for where AI eliminates manual work without adding fragility
Nice to have
You've owned a fundraising process or been the key finance partner in one. You know how to organize a data room, work through diligence questions, and build investor confidence through metrics and narrative
You've managed a transition from outsourced to in-house accounting
You've worked on rev ops, pricing strategy, or sales commission structures alongside core FP&A work
Joining us
To start, you'll have a handful of conversations with our team and founders. If there is mutual excitement, we'll invite you to the office where you'll work on a small project and meet the team.
