We’re on the hunt for a sharp, entrepreneurial Senior Accountant to join our growing team. In this role, you won’t just be preparing financial reports — you’ll be providing clarity, structure, and strategic support to help our new Members get onboarded accurately and efficiently. You’ll manage the implementation of new Members, and contribute to the evolution of our tech-first, AI-powered financial services. If you love clean ledgers, thoughtful analysis, and streamlining processes — you’re in the right place. What you'll achieve Deliver a smooth, accurate, and delightful onboarding experience to all of our new Members. Set up clean, audit-ready books by managing balance sheets, P&L statements, and account reconciliations — so our Members can sleep better at night. Track key assets, liabilities, and loan amortizations, ensuring each Member has a crystal-clear view of their financial position.

Recommend smarter systems and accounting automation that save time and reduce errors — freeing up our Members to focus on growing their business. Partner with our product and technology team to build the next generation of automation in Member onboarding.

Deep knowledge of GAAP and strong Excel skills — pivot tables and VLOOKUPs are your love language. Prior experience implementing accounting software or systems is a big plus. Tech-forward — you’ve used AI and automation tools in accounting and are always looking to push the envelope on what technology can solve in your workflows. Soft Skills & Abilities Independent and collaborative — you thrive with autonomy but love team wins. Strong project manager who meets deadlines, even when juggling multiple Members and priorities. Excellent communicator who can explain the “why” behind the numbers. Naturally detail-oriented, organized, and resourceful. Passionate about improving processes and learning new tools.
