Senior Financial Accountant

Senior Financial Accountant

At most companies, a Senior Financial Accountant is a cog in a well-oiled close machine. The process exists, the templates are built, the checklist is handed over. Here, the function is still maturing while the business is moving.

You will be expected to both execute core accounting work reliably and improve the systems around it in real time. Some processes will be undocumented. Some cycles will require triage. You will be expected to think, not just execute.

The Mission

Boom's development of Overture will change how the world moves. The immediate development of the Superpower turbine will ensure we have the capital to make it happen. But none of this development happens without the financial infrastructure to support it. This role owns the general ledger and supports financial reporting - the foundation every investment decision, capital raise, and growth milestone is built on. Without reliable close and reporting execution, the company cannot scale responsibly or pursue the ambitions that make Boom worth working for.

What you'll do

• Execute month-end close end-to-end - journal entries, reconciliations, accruals, and variance explanations - every balance traceable, documented, and explainable at a business-driver level
• Support financial reporting and audit readiness by maintaining clean, well-documented workpapers and supporting schedules
• Identify recurring issues and manual workarounds and actively work to reduce or eliminate them, including through automation and AI tools
• Research, evaluate, and account for complex accounting areas and transactions, including equity, investments, interest, taxes, etc., resolving questions with confidence and clarity
• Manage and support the accounting systems and associated projects
• Support procurement, facilities, and legal teams through expert knowledge of the systems and great working relationships

This job is demanding and rewarding

Close and financial reporting cycles are time-pressured, and precision is non-negotiable even when things get messy. Some processes will be incomplete when you arrive. Unexpected issues will surface mid-close, and you will be expected to triage them independently. You will also balance close with other projects and company priorities - that is the nature of a lean, scaling team.

What you get in return is rare. Your contribution is directly visible, the work materially impacts how the business operates, and the development trajectory is steep. If you want to execute inside a fully built machine, this is not the role. If you want to build something, develop fast, and become a cornerstone of a team supporting one of the most ambitious engineering programs in the world, this is an unusually high-value seat.

What you bring to the table

• 3-6 years of experience including public accounting start preferred
• Certified Public Accountant (CPA) certification required
• Strong organizational, time management, and interpersonal skills
• Passion for working in a high paced environment and constantly learning through exposure to new areas
• Excellent initiative and ability to analyze, question and summarize data for decision making
• Clear and effective verbal and written communication skills
• Experience interacting with upper management and operations personnel
• Strong inclination to prepare for and comply with deadlines around the monthly close cycle
• Ability to work within multiple systems including GL, PO, invoice processing system, etc.
• Ability to multi-task in a fast-paced environment
• Aptitude to be responsive and helpful, both within the department and to other departments
• Ability to work in a changing environment, with a desire to identify and own regular improvements
• Proficiency with spreadsheets and modern productivity tools, including AI-assisted tools
