• Design and establish public-company-level internal controls, accounting policies, SOPs, and financial reporting processes.
• Play a key role with external audits, technical accounting matters, and compliance processes, coordinating effectively with auditors, tax advisors, and other third-party partners.
• Evaluate accounting treatment for research collaborations, vendor arrangements, equity activity, and other transactions common to biotechnology companies, applying sound judgment and consistent controls.
• Build scalable financial processes and systems that support organizational growth, strengthen governance, and prepare the company for future financing and operational milestones.
• Partner with scientific, clinical, operational, and executive leaders to translate complex business activity into clear financial visibility, budget accountability, and actionable insights.
• Oversee cash forecasting, expense analysis, accrual management, and budget-to-actual reporting to support disciplined resource allocation across R&D and corporate functions.
• Provide leadership, coaching, and performance feedback to team members; participate in hiring, development planning, and year-end review processes.

Requirements

• Bachelor's degree in Accounting, Finance, or a related field required; CPA preferred and advanced degree a plus.
• Minimum of 8-10 years of progressively responsible accounting and controllership experience, with direct experience in biotechnology, life sciences, or similarly complex industries.
• Deep knowledge of GAAP, internal controls, financial reporting, and audit coordination, with demonstrated ability to operate in a high-growth environment.
• Strong skills in accounting systems, general ledger management, financial analysis, and reporting; experience supporting ERP implementation or process optimization is highly valued.
• Experience with SEC reporting frameworks and GAAP compliance for public entities is highly desirable.
• Working knowledge of life sciences business models, including R&D expense management, accruals, clinical and preclinical spend, vendor oversight, and development-stage planning.
• Excellent judgment and decision-making skills, with the ability to apply critical thinking, problem-solving, and information ordering to complex and time-sensitive issues.
• Strong communication skills, with the ability to present financial information clearly to scientific and executive stakeholders.
• Proven ability to collaborate cross-functionally and operate with integrity, discretion, and accountability in a mission-driven environment.
