About Us Liquid Instruments builds next-generation test and measurement technology for engineers and scientists pushing the boundaries of discovery. Our founders came out of the Australian National University, with research roots tied to NASA’s Jet Propulsion Laboratory. Today, we use deep expertise in high-speed digital signal processing to build software-defined test and measurement platforms. One reconfigurable FPGA-based device replaces racks of traditional lab equipment, delivering flexibility, performance, and cost efficiency. We’re a growing, venture-backed company with teams in San Diego, California, and Canberra, Australia. Our culture is collaborative and technically curious, and it values ownership, clarity, and impact across time zones. The Role You’ll own revenue recognition and related accounting across our products and subscriptions and help build the systems that support our growth. Day to day, that means complex invoicing, order terms and conditions, billing review, ASC 606 revenue recognition, and reconciliations. You’ll have a solid understanding of accounting and GAAP compliance and play close attention to detail. You’ll support the month-end close and work with Sales and Operations to make sure what we sell is accounted for correctly. The Revenue Accountant will report to the Accounting Controller and work on-site in our Del Mar office. What You’ll Do
Recognize revenue under US GAAP (ASC 606): identify performance obligations, determine transaction price, and allocate consideration across hardware, software, subscriptions, and warranties
Account for hardware-specific items: shipment and delivery terms, acceptance provisions, returns and RMAs, warranties, and channel/distributor arrangements
Prepare monthly revenue, deferred revenue, and contract asset/liability entries and reconciliations
Support inventory and COGS accounting, including revenue-to-cost-of-sales matching on shipments
Support month-end close: account reconciliations, AR aging review, revenue entries, and supporting schedules with variance analysis and flux commentary
Prepare and review journal entries and customer transactions across our ERP, website, CRM, and IMS
Work cross-functionally with Sales, Marketing, Product, Billing, and Operations on new offerings, non-standard terms, promotions, pricing changes, and operational impacts on revenue
Optimize our systems by building, documenting, and improving revenue controls and workflows, and automate as the company scales
Run accounts receivable: invoicing, payment application, collections, and account research
Resolve invoicing, payment, and balance issues before they escalate
Record electronic payment deposits accurately and post them on time in our ERP
Follow up with customers on payments, balances, portal applications, and discrepancies, with clear documentation and a professional tone
Communicate revenue impacts clearly to non-accounting partners and influence business decisions with a balanced technical and operational perspective
Keep internal and external stakeholders informed on billing, payments, account status, and reporting
Serve as a subject matter expert within the revenue organization and a trusted partner to other departmental teams
Provide backup assistance to expense management and sales tax activities

Sharp attention to detail and the ability to work independently in a fast-moving environment
Clear, professional communication with customers, vendors, and teammates, including the ability to explain accounting to non-finance colleagues
