About the Role

As Finance Manager at Solstice, you will build and own our financial operations, reporting directly to the co-founders. You will be our first dedicated finance hire — responsible for standing up clean, audit-ready books, running payroll and compliance, and building the financial models and reporting our leadership team and board rely on. This is a hands-on, builder role: you won't inherit a finance function, you'll create one.

Responsibilities

  • Own the accounting function end-to-end, including monthly close, accounts payable and receivable, and financial statement accuracy.
  • Own invoicing and billing for our pharma brand clients, and drive accounts receivable collections — chasing down late payments, managing customer payment terms, and keeping days sales outstanding (DSO) in check.
  • Run payroll and ensure tax and regulatory compliance across all jurisdictions we operate in.
  • Build and maintain our core financial models, including a three-statement model, cash flow forecasts, and burn/runway tracking.
  • Design and implement financial controls, expense policy, and approval workflows as we scale headcount and spend.
  • Prepare board-ready reporting packages and partner with the co-founders on budgeting and financial planning.
  • Manage relationships with our bank, auditors, and any outside accounting or tax support.
  • Lay the groundwork for the systems and processes a growing finance team will build on.
  • Cleaning up and professionalizing our books, chart of accounts, and close process.
  • Setting up a repeatable invoicing process for client billing and owning the A/R collections cadence — follow-ups, aging reports, and escalations for overdue accounts.
  • Implementing an expense policy and spend controls as the team grows.
  • Building a reliable three-statement financial model and monthly board reporting package.
  • Managing payroll, benefits administration coordination, and compliance filings.
  • Partnering with the co-founders on budgeting, forecasting, and fundraise-related financial diligence.
  • Selecting and implementing the accounting/finance tooling stack (e.g., QuickBooks, bill pay, expense management).
  • Establishing the financial rigor and documentation standards that will support our next fundraise and eventual audit.

Requirements

  • Have 4–8 years' experience in accounting or finance, ideally including time in banking or strategic finance followed by an early-stage startup environment.
  • Can independently build and maintain a three-statement model and board-ready reporting without heavy oversight.
  • Are comfortable being tactical and hands-on — this role is about accuracy and execution, not high-level strategy.
  • Have a strong grasp of GAAP, payroll compliance, and the fundamentals of financial controls.
  • Learn fast, execute relentlessly, and excel in ambiguous, fast-paced, in-person startup settings.
  • Are organized, reliable, detail-oriented, and proactive.
  • Take initiative and enjoy working collaboratively as a great teammate with no ego.
