Boom’s outstanding team comes from places like Amazon, SpaceX, Scaled Composites, and Virgin Galactic. Team members have collectively contributed to 40+ new air and space vehicles, including the Falcon 9, Virgin SpaceShipTwo, and the Joint Strike Fighter.
The company is backed by venture capital firms including Emerson Collective, Y Combinator, Caffeinated Capital, and SV Angel as well as individuals including Sam Altman, Paul Graham, Ron Conway, Michael Marks, and Greg McAdoo.

Role Overview
Boom is building a world-class accounting & finance team to support its mission of restoring supersonic commercial flight. We are looking for a highly motivated Staff Accountant to join our growing team. 
Your primary responsibilities will be: owner of general journal entries in Boom’s accounting system; responsible for accounts payable, payroll processing, and cash reconciliations; play a key role in the month-end close process and manage various asset and liability account reconciliations; design & implement new accounting procedures and processes that don’t exist today; assist with technical accounting research whenever necessary, support internal controls improvements, and other ad hoc projects.
You should have exceptional operational accounting skills, and not afraid to “own the general ledger”. You will be the “go-to” person for all things general ledger. You should be confident working in other systems too (payroll processing, a PO system, expense management system), and understand how those impact the GL. You should also be confident in making recommendations on accounting improvements, and willing to own & implement. You will need to work cross-functional with other teams, particularly through a good understanding of POs, budget ownership, and expense categorization. You should also be comfortable working independently at times.
Working in a startup environment means taking on unexpected responsibilities and attempting tasks that no one in the company knows how to do. The successful candidate has a resourceful, can-do approach to these demands and enjoys the continuous learning curve of a startup.
The Staff Accountant will report to the Accounting Manager and will be a member of Boom’s growing accounting & finance team.
