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. You will:

• 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.

What You'll Be Working 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

Ideal Candidate Profiles

This is a unique opportunity for candidates from many backgrounds, including:

• A finance operator from an early-stage startup ready to own a function independently rather than as part of a larger team

• A detail-driven generalist with strong financial acumen who wants deep exposure to how an early-stage company is actually run

• A former banker or accountant (Big 4 ) who has moved into a startup finance seat and wants full ownership

You Might Be a Good Fit if You:

• 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

Disclaimer

This position is not all glamor. It involves a lot of behind-the-scenes work: reconciliations, policy-writing, and closing the books every month. Everyone at Solstice is a builder and is not afraid to lay the bricks themselves. This role is not for pure strategists — we are looking for doers.
