Senior Accountant

About Chamber Chamber Cardio is rebuilding how cardiovascular care is delivered in the United States. We partner with cardiologists, payers, and patients to bring a value-based model to a specialty that has long operated in fee-for-service. Cardiovascular disease remains the leading cause of death in this country — Chamber exists to change that trajectory, one heart at a time. We are a small, mission-driven team building foundational infrastructure for a new category of care. The decisions made today will shape how this company operates for years to come. About the Role We are hiring our first dedicated Senior Accountant to build Chamber’s accounting function from the ground up. Reporting directly to the Head of Finance, you will own the operating rhythm of our financial close, stand up the systems and processes that the company will run on, and lead Chamber through its first formal external audit. This is a true zero-to-one build. The standards you set, the policies you write, and the rigor you bring will become the operating system for the finance organization for years. What You’ll Own Month-end close — lead a clean, timely, well-documented close cycle. Financial reporting — produce monthly internal financial statements and the supporting analytics that feed our board package. Audit — own audit prep and serve as Chamber’s primary point of contact for external auditors during our first full audit. Accounts payable — design, document, and operate the end-to-end AP process: vendor onboarding, bill review, payments, and expense management. Balance sheet reconciliations — own recurring reconciliations across cash, prepaids, fixed assets, accruals, and intercompany. Accounting policies and controls — build the policy library (revenue recognition, capitalization, lease, etc.) and design a stage-appropriate internal control environment. Cross-functional partnership — work alongside Operations, People, and Clinical leadership on the accounting implications of new contracts, programs, and hires. What Success Looks Like AT 90 DAYS Close process is owned end-to-end with replicable reporting and infrastructure. AP process documented and live. Current-state diagnostic complete with a prioritized roadmap. AT 6 MONTHS Close consistently completed on target date. Monthly board reporting is reliable and largely automated. Audit readiness work well underway. AT 12 MONTHS First full external audit completed with a clean opinion. Close cycle at 5 business days with all reconciliations current. AP fully automated; accounting infrastructure is ready to support 2× company scale. What You’ll Bring 5–8+ years of progressive accounting experience, ideally with a public accounting foundation followed by industry experience at a venture-backed or scaling company. Active CPA (or CPA-eligible with imminent licensure). Demonstrated end-to-end ownership of month-end close at a high-growth company. Strong technical accounting under US GAAP. Experience leading or supporting an early-stage external audit. A builder’s mindset — you have designed and documented processes from scratch, not just operated within someone else’s framework. Comfort with ambiguity, scrappy resourcefulness, and unusually high attention to detail. Bonus Points Healthcare experience — especially value-based care, MSO/management services, or provider services. QuickBooks power-user. Experience implementing AP automation and expense tools (Ramp, Brex). Exposure to revenue recognition for service contracts or risk-based arrangements. Familiarity with payor data, capitation, or shared-savings accounting. CHAMBER VALUES Our values guide how we lead, collaborate, and care: Low Ego: We stay grounded, curious, and open to feedback. Empathy: We build trust through compassion and thoughtful communication. Courage: We take action, think critically, and challenge ideas respectfully.
