Corporate Controller

MatX is on a mission to make the world’s best AI models run as efficiently as possible—accelerating global progress in AI quality and accessibility. We are building cutting-edge AI infrastructure at the intersection of hardware and software, and our team is growing quickly.

MatX is seeking a dedicated and experienced Corporate Controller to lead our accounting function and ensure the integrity, accuracy, and scalability of our financial operations as we grow. This role will serve as the guardian of financial data integrity — going beyond compliance to drive transparency, support executive decision-making, and deliver high-quality insights to internal leadership, investors, and the Board of Directors.

As a key member of the Finance team, you will oversee outsourced accounting resources, establish scalable accounting infrastructure, strengthen governance, and ensure financial rigor across a fast-moving, engineering-heavy organization. This is a hands-on leadership role for an experienced accounting professional who thrives in early-stage environments.

If you are a builder, and enjoying partnering with teams to bring rigor and transparency to complex, hardware-driven economics - this is the role for you.

• Own and oversee all core accounting functions, including Accounts Payable, Accounts Receivable, General Ledger, Treasury, Fixed Assets, and Project Accounting.
• Lead a timely and accurate monthly, quarterly, and annual close, ensuring GAAP-compliant financial statements.
• Manage and review work performed by outsourced accounting providers, ensuring quality, timeliness, and adherence to internal standards.
• Design, implement, and maintain accounting policies, procedures, and internal controls appropriate for a scaling semiconductor startup.
• Coordinate payroll processing in partnership with a third-party payroll provider, including review of payroll entries and reconciliations.
• Serve as primary accounting owner for audits, reviews, and investor diligence requests.

• Partner with Engineering and Operations to ensure accurate accounting for R&D spend, wafer fabrication, tape-out costs, mask sets, non-recurring engineering costs, multi-project wafer runs, packaging, testing, and inventory.
• Track and account for tape-out milestones, including capitalization vs. expense treatment in accordance with GAAP.
• Support program-level cost tracking across silicon development phases (pre-tape-out, tape-out, bring-up, production).
• Ensure appropriate treatment of long-lead manufacturing commitments, prepaid expenses, accruals, and supplier deposits.

(Note: This role does not manage the engineering tape-out process, but ensures financial visibility, controls, and accurate accounting of it.)

• Respond to financial requests from investors, lenders, and strategic partners.
• Partner with the Finance Lead to prepare quarterly Board materials, including financial statements, KPIs, and variance analysis.
• Produce recurring reporting packages, dashboards, and metrics to support executive and Board decision-making.
• Perform analytical work such as ROI, NPV, breakeven analysis, and cost-to-scale assessments to support strategic initiatives.

• Own day-to-day accounting operations in ERP, ensuring data integrity and proper controls.
• Perform and review bank reconciliations, cash management, and treasury activities.
• Partner cross-functionally and within Finance to ensure accurate tracking of departmental spend, headcount, customer acquisition costs, R&D investments, and cost of goods manufactured.
• Lead accounting process improvements and system enhancements to support scale, including readiness for future ERP migration if needed.

• Act as a trusted finance partner to Finance, Operations, Engineering, and executive leadership.
• Lead accounting system scalability and ERP readiness, including documenting requirements, improving data hygiene and controls in QuickBooks Online, leading on ERP selection, and supporting a future migration as the company outgrows QBO within the next 12 months.
• Provide clear, timely, and thoughtful responses to leadership on accounting, financial, and operational questions.
• Bring rigor, transparency, and sound judgment to financial decision-making in a dynamic startup environment.

By month 12, a successful Controller will have:

• A predictable, on-time monthly close with high confidence in numbers and minimal rework

• A well-defined ERP readiness plan, including requirements, data hygiene, and implementation timing
• Strong trust and credibility with Finance leadership, Engineering, and Operations

• Active CPA and Bachelor’s degree in Accounting (or equivalent).
• 10+ years of progressive accounting experience, including hands-on close ownership.
• Experience in ERP transition.
• Experience accounting for tangible, manufactured products (hardware, semiconductor, or complex supply chains strongly preferred).
• Solid understanding of payroll, treasury, bank reconciliations, and internal controls.
• Strong organizational skills with high attention to detail and ability to manage multiple priorities.
• Excellent written and verbal communication skills, including presenting financial information to executives and investors.
• Comfortable operating in ambiguity and building structure in a startup environment.
  

• Semiconductor, hardware, or deep-tech startup experience.
• Expertise in cost accounting, inventory accounting, or R&D capitalization.
