About

The Role

iota is looking for a hands‑on finance leader who thrives in early‑stage environments and wants to build. This role is ideal for a senior staff accountant or early FP&A professional who has a strong foundation in accounting but also wants to step into broader ownership of budgeting, burn‑rate tracking, process creation, and day‑to‑day financial operations.

What You’ll Do Financial Operations & Accounting

• Oversee day‑to‑day accounting operations, including AP, month‑end close, reconciliations, and journal entries.
• Partner with external accounting and PEO teams to ensure accurate payroll, benefits, payroll tax processes and day‑to‑day accounting.
• Maintain the general ledger and ensure compliance with US GAAP.
• Support monthly, quarterly, and annual financial statements; prepare flux analysis; prepare schedules for audits and reviews.
• Manage the company’s use tax compliance, including preparing, documenting, and filing periodic returns. Work with the tax firm to support additional filings such as business property tax and franchise tax.

Budgeting, Forecasting & Reporting

• Build and manage budgets in partnership with department leads and the fractional CFO; provide real‑time visibility into actuals vs. budget.
• Track and forecast burn rate, headcount costs, vendor spend, and runway—proactively flagging risks and insights.
• Develop dashboards and reporting that help leadership make informed decisions.

Systems, Processes & Internal Controls

• Implement early financial systems, tools, and scalable processes (e.g., expense management, purchasing flows, cost tracking).
• Create simple but effective internal controls appropriate for an early‑stage company.
• Lead vendor onboarding and contract tracking; partner with legal and operations teams as needed.
• Creating and updating expense and travel policies and maintaining internal compliance.

Cross‑Functional Support

• Work closely with R&D, Clinical, Operations, and HR to align finance with business needs.
• Help model scenarios for hiring, lab expansion, grants, capital planning, and investment decisions.
• Support board reporting, investor updates, and fundraising preparation.

Who You Are

• 5–8 years of accounting experience (startup or high‑growth environment strongly preferred).
• Strong understanding of US GAAP with hands‑on accounting capability—but also excited to expand into FP&A.
• Scrappy, detail‑oriented, and comfortable wearing many hats—this role spans accounting, operations, and finance strategy.
• Someone who wants to own the finance function day‑to‑day, not just support it.
• Comfortable with ambiguity, building processes from scratch, and creating structure where none exists.
• Experience with finance systems;
  Quick Books and Ramp a plus.

Why This Role Is Exciting

• You’ll be joining at the formation stage of a new, well‑funded company—your work will directly influence how the company grows.
• You’ll partner closely with experienced leaders (CEO, COO, fractional CFO) and gain exposure to strategic decision‑making.
• You’ll build foundational systems from the ground up, not inherit legacy processes.
• Clear growth path into Finance Manager or Controller as the company scales.

Compensation Range: $120K - $160K
