Every part of our robots is designed and produced in-house—from motor coils to AI—reflecting our vertically integrated approach. At 1X, you’ll own real projects, be recognized for your achievements, and rewarded based on merit.

We are seeking a Senior Accountant with strong technical and operational accounting experience to play a key role in building and scaling our finance function.

• Lead full-cycle accounting operations across AP/AR, vendor management, invoicing, payment processing, and collections support as needed

• Prepare supporting schedules and manage deliverables for external financial audits
• Support federal, state, and local compliance requirements including tax filings, business licenses, and regulatory reporting
• Conduct technical accounting research and prepare documentation on new or complex transactions
• Partner closely with HR, Supply Chain, Engineering, and external vendors to ensure accurate, timely financial operations
• Identify inefficiencies and propose process or systems improvements as we scale our financial infrastructure
• Serve as a subject matter expert for AP processes, ERP workflows, and general accounting procedures
• Help mentor junior team members as the finance function grows

• 5–7+ years of progressive accounting experience, ideally in a dynamic or high-growth environment
• Bachelor’s degree in Accounting, Finance, or related field
• CPA preferred
• Strong understanding of U.S. GAAP and internal control principles
• Advanced reconciliation, month-end close, and journal entry experience
• Proven AP and broader accounting operational experience (not AP-only)
• Ability to research and interpret technical accounting issues
• High proficiency in Excel/Google Sheets and modern accounting systems/ERPs (Net Suite, RAMP, Stampli, etc.)
• Ability to manage competing priorities, meet deadlines, and collaborate cross-functionally
• Strong analytical, organizational, and communication skills
• Detail-oriented with a proactive, problem-solving mindset
• Startup or hardware experience a plus

• Big 4 public accounting experience and/or manufacturing industry exposure
• Experience supporting or leading systems implementations
• Familiarity with SOX or internal control frameworks

This role is expected to be onsite 5 days per week in Palo Alto.

• Salary Range: $120,000 - $140,000
