The Senior Accountant will help build the accounting function, including its processes, controls, close calendar, and structure as the company grows. Responsibilities span close ownership, bookkeeping oversight, AP and AR, platform-to-ledger data integrity, inventory accounting, accounting policies, financial statements, and audit or review readiness. The role owns US multi-state sales tax compliance and supports international indirect tax compliance, including Canadian GST/HST and EU VAT. It also supports the company’s multi-member LLC partnership tax process and maintains daily and weekly cash flow reporting. MellowSleep is a fast-growing home goods brand selling through Shopify, Amazon, TikTok Shop, and wholesale retail channels, with international expansion underway. The role is remote and US-based.
