Senior Accountant

Who We're Looking For

Quantum Space is redefining mobility and maneuverability in orbit. Our high-delta-V spacecraft platforms support national security, civil, and commercial missions where propulsion capability and rapid execution matter.

We are hiring a Senior Accountant to serve as a financial backbone across the company's growing operations, from project setup through audit close. You will own month-end close, project accounting, and government contract compliance in a fast-paced aerospace and defense environment where financial accuracy directly supports flight programs.

We are looking for someone detail-driven, systems-minded, deeply fluent in Deltek Costpoint, and comfortable operating at the intersection of GAAP, FAR, and DCAA requirements.

Where You'll Make an Impact

• Own monthly, quarterly, and annual close activities including journal entries, reconciliations, accruals, and financial statement support
• Drive project accounting across labor distribution, indirect rate monitoring, revenue recognition, and contract setup in Deltek Costpoint
• Maintain general ledger integrity and ensure accuracy of financial data across the business
• Review employee timesheets and labor charging for compliance with company policy and government contracting requirements
• Lead account reconciliations and variance analysis tied to project and operational performance
• Support accounts payable, billing, cash management, and payroll accounting functions
• Serve as a key contributor on annual financial statement audits and DCAA and compliance reviews
• Partner with program managers and operations leadership on financial reporting and project performance analysis
• Identify opportunities for process improvement, automation, and Costpoint system optimization
• Help develop and document accounting policies, procedures, and internal controls

What It Takes

• B.S. in Accounting, Finance, or related field
• 4 to 7+ years of accounting experience, preferably in government contracting, aerospace, or defense
• Hands-on experience with Deltek Costpoint required
• Strong understanding of GAAP and government contracting regulations including FAR and CAS
• Advanced proficiency in Microsoft Excel and financial reporting tools
• Unanet, Power BI, or comparable ERP and reporting platforms a plus
• Familiarity with timekeeping and compliance systems used in government contracting
• Excellent analytical, organizational, and problem-solving skills
• Ability to manage multiple priorities and deadlines in a fast-moving environment
• Strong communication skills and ability to work cross-functionally with operational and program teams

Strongly Preferred Experience

• CPA or active CPA candidate
• Experience supporting DCAA audits, indirect rate submissions, and government contract compliance
• Prior experience in a high-growth or startup environment
• Familiarity with project-based accounting and contract lifecycle management

Why Quantum Space

• Build the financial foundation behind spacecraft that actually fly, rapidly and repeatedly
• Own real authority across close, compliance, and project accounting, not just task execution
• Work with a team pushing the frontier of high-mobility space logistics
• Competitive compensation, equity, and top-tier benefits including medical, dental, vision, generous leave, HSA, 401(k) matching, and equity sharing
