Job description

About Us

Source is building the operating system for global commercial construction. We're reengineering how a $1T+ industry moves money not just digitizing procurement workflows, but redesigning the financial infrastructure behind every project, purchase, and vendor relationship.

We're an AI-native managed marketplace operating at the intersection of technology and high-stakes capital deployment. Our clients - Marriott, Hilton, Hyatt, Disney, and others - trust us to manage hundreds of millions in annual purchasing volume across complex, multi-vendor, multi-phase projects. That trust is earned through precision: the right products, at the right price, on the right timeline, with the financial controls to back it up.

If you're energized by building financial systems that can scale, and want a seat at the table as we grow - through organic expansion, active M&A, and a staged transformation toward a platform business - we'd love to meet you.

What You’ll Own

Financial Leadership & Strategy

• Own the full finance function, including FP&A, accounting, reporting, and cash flow management across a multi-workstream business (project purchases, fee revenue)
• Serve as a strategic thought partner to the CEO on capital allocation, revenue model evolution, and the financial implications of Source's staged AI transformation
• Build and maintain the financial architecture that supports Source's transition from a managed services business to a hybrid platform model
• Lead annual budgeting, quarterly forecasting, and rolling financial planning processes

Project-Based & Construction Accounting

• Own all project accounting operations across Source's active procurement portfolio, including cost-to-complete tracking, draw schedules, client billing, and detailed analysis at the project level
• Maintain clean financial separation across concurrent projects, ensuring revenue recognition and cost allocation meet GAAP standards in a project-based construction context
• Enforce internal controls specific to procurement-in-trust workflows, where Source manages significant client capital on behalf of owners

M&A & Corporate Development Finance

• Lead financial due diligence on acquisition targets, including quality of earnings analysis, revenue concentration assessment, integration cost modeling, and earnout structure design
• Build valuation models and deal scenario analyses for prospective targets across Source's priority M&A strategies (client list expansion, geographic expansion, talent acquisition)
• Support integration planning post-close, including entity consolidation, intercompany accounting, and performance tracking against earnout milestones
• Partner with legal counsel, internal stakeholders, and external teams to advise on deal structure, asset vs. entity transactions, and risk mitigation

Multi-Entity & Operational Finance

• Design the reporting and integration framework as Source leverages M&A and advise on multi-entity structures and timing of consolidation
• Ensure financial visibility at both the entity and consolidated level, supporting portfolio-level decision-making by the executive team and board
• Manage relationships with banking partners, external auditors, and needed fractional/advisory resources

Team & Systems

• Assess, hire, and develop the internal finance team as the business scales
• Own the selection and implementation of financial systems that support Source's ERP-agnostic platform strategy and growing operational complexity

About You

Must-Haves

• 10+ years of progressive finance experience, with at least 3–5 years in a senior finance leadership role
• Direct, hands‑on experience with project-based construction accounting - including draw management, fraud oversight, project segmentation, and revenue recognition in a construction or procurement context; this is non-negotiable
• Experience in M&A - either at a company that executed acquisitions or in a transaction advisory/investment banking/corporate development capacity; must be able to own diligence and earnout modeling independently
• Background in a venture-backed startup or high‑growth technology company, with fluency in tracking key metrics, cohort economics, and investor‑grade reporting
• Experience building or operating within a multi‑entity or multi‑business‑unit structure where financials roll up to a consolidated parent
• AI‑native by default - you don't bolt AI onto existing processes; you design with it from the start. You have hands‑on experience identifying automation opportunities, mapping workflows for AI intervention, and building or specifying systems that reduce human labor in repetitive, high‑volume finance and operational processes.

Strong Signals

• Exposure to hybrid business models - particularly companies with both a services/managed business and a software or platform revenue line
• Comfort operating as a "builder" - this is not a role for someone who inherits a mature function; Source's finance infrastructure is still being developed
• Experience in commercial real estate, construction technology, procurement, or hospitality‑adjacent businesses
• Familiarity with earnout-based deal structures, integration accounting, and post‑close financial performance tracking
• Prior experience with external capital raises or board‑level financial reporting
• Operationally fluent - you understand how the money actually moves through the business, not just how it appears on the P&L
• You think in systems and are constantly looking for areas to improve: inputs, handoffs, failure modes, and feedback loops - and you know how to translate that thinking into actionable infrastructure, whether you're working with an engineering team, or an external vendor
• A strong communicator who can translate complex financial structures for non‑finance executives and board members
• Highly autonomous and comfortable in ambiguity - Source is a fast‑moving company and this role will require you to build while the plane is flying
• Collaborative and low‑ego - you'll work closely with the CEO and the broader exec team and need to be a trusted partner, not a gatekeeper

Why Join Us

• High‑leverage finance leadership role at the inflection point between services and platform business
• Direct line to the CEO and board; genuine seat at the strategic table
• M&A activity is live and accelerating - you won't be building models for theoretical deals
• The financial architecture of this company is still being shaped; you'll leave fingerprints on it permanently
