About Us

Chariot Defense is a defense technology company that designs and manufactures a family of power products for the U.S. military and its allies. We believe that credible deterrence of armed conflict and winning if deterrence fails, requires more than just the best drones, sensors, weapons, electronic warfare systems, and command & control capabilities. Those critical components will require sustained electric power in austere and resource-constrained environments. Moreover, military units must be able to turn off the trucks and generators that generate this power to hide and survive. In other words, power generation must be decoupled from power consumption. Chariot Defense’s products enable exactly this capability, allowing U.S. and allied militaries to be more lethal and survivable. We hope you will join us on this mission.

About the Role

Chariot Defense is seeking a Cost Accountant to join our Finance team. Reporting to the Head of Operations, you will own the accuracy of product and program costs as we scale hardware production. You will sit at the intersection of Finance, Manufacturing, and Supply Chain—valuing inventory, tracking WIP, allocating overhead, and making sure every unit we build and every contract we deliver is costed correctly and in compliance with government contracting standards. We are looking for a hands-on, detail-driven accountant who is comfortable on the shop floor as well as in the ERP, and who wants to help build cost accounting processes from the ground up.

Key Responsibilities

Product Costing: Build and maintain standard costs, bills of materials (BOM) costing, and routings for our power products; perform periodic standard cost roll-ups and revaluations.
Inventory & WIP: Own accounting for raw materials, WIP, and finished goods, including cycle count reconciliations, physical inventory support, and excess & obsolete (E&O) reserve analysis.
Month-End Close: Prepare cost-related journal entries, accruals, and reconciliations (inventory, COGS, WIP, overhead) to support a timely, accurate close under U.S. GAAP.
Variance Analysis: Analyze and explain purchase price, labor, material usage, and overhead variances; translate findings into actionable insights for Operations and leadership.
Overhead & Indirect Rates: Develop and maintain overhead allocation methodologies and indirect rate pools (fringe, overhead, G&A) consistent with FAR Part 31 and CAS requirements.
Program & Contract Costing: Track costs by program and contract, support estimates-at-completion (EACs), and provide cost data for pricing proposals and milestone-based revenue recognition (ASC 606).
Compliance & Audit Support: Maintain DCAA-compliant timekeeping and job-costing practices; prepare schedules and documentation for financial audits and DCAA/DCMA reviews.
Systems & Process: Improve cost accounting workflows in our ERP/MRP (e.g., NetSuite), including item costing, work orders, and assembly builds; identify opportunities to automate manual reporting.
Cross-Functional Partnership: Work closely with Manufacturing, Supply Chain, and Engineering to understand production flows, validate BOM accuracy, and support make-vs-buy and margin analyses.

What We're Looking For

Extraordinary conscientiousness. You commit to what you're going to do and follow through without fail.
Precision with a builder's mindset. You care about getting the numbers right and about building the processes that keep them right.
Curious about how things are made. You'd rather walk the production floor than guess at a cost driver.
Collaborative by nature. You seek input from all stakeholders and explain cost findings clearly to non-finance partners.
Resilient and steady in a demanding, fast-paced work setting, making sound decisions with imperfect or incomplete information and adapting when priorities shift.
Transparent, diligent, and highly responsive in your communication with colleagues across the company.

Qualifications

Bachelor's degree in Accounting (or Finance).
2-5 years of cost or inventory accounting experience at a hardware, defense, aerospace, automotive, or industrial manufacturing company.
Solid understanding of U.S. GAAP, standard costing, inventory valuation, and overhead absorption.
Familiarity with government contracting cost principles (FAR Part 31, CAS, DCAA) and job/program costing.
Hands-on experience with an ERP/MRP system such as NetSuite (preferred), Costpoint, SAP, or similar.
Advanced Excel skills (lookups, pivot tables, building cost models).
Willingness to work onsite in our San Bruno, CA, office 5 days per week, as well as extended and weekend hours when necessary (e.g., during close or physical inventory).

Preferred:

CPA, CMA, or progress toward either.
Experience supporting indirect rate development, incurred cost submissions, or DCAA audits.
Exposure to ASC 606 revenue recognition on milestone-based hardware contracts.
Experience in an early-stage or high-growth company where you helped build processes from scratch.

Chariot Defense

Transportable hybrid power systems for defense

Chariot Defense designs transportable, software-defined hybrid power systems (Amphora) that store, convert, and route energy to power drones, sensors, radios, electronic warfare, and directed-energy systems in the battlefield. Amphora units act as power hubs, pulling energy from generators, vehicles, and solar, and distributing it through software-controlled power management with low electronic, thermal, and acoustic signatures. It differentiates itself by offering field-ready, compact platforms that combine storage, conversion, routing, and a battlefield operating system for integrated energy management across platforms. Its goal is to scale Amphora production, build a battlefield power OS, and expand engineering for defense customers like the Army and DIU.
