## Job description

About Lumafield:

Lumafield was founded in 2019 to upgrade manufacturing.

We are engineers with deep experience across the product development cycle, from initial ideas to shipping hardware, across industries and specializations, who became frustrated by the cost and complexity of modern manufacturing. So we decided to upgrade it.

Engineers make million-dollar decisions every day, and they need tools that give them the greatest possible insight into their products. By offering unprecedented visibility into products, as well as AI-driven tools that highlight problems and generate quantitative data, Lumafield promises to revolutionize the way complex products are created, manufactured, and used across industries. We started with industrial CT scanning, which for us was the most valuable but underutilized tool in the manufacturing toolbox, enabling us to rapidly inspect essential components non-destructively.

We rebuilt the whole system, from X-ray capture, to computer vision analysis, to web-based collaboration, to the entire business model, making the most advanced manufacturing tech more accessible to every industry. Our company, like our platform, is designed for upgrades. We’re building for greater intelligence, autonomy, and speed. For deeper vision, operational excellence, and powerful insights. And then we'll upgrade it all again.

Lumafield is headquartered in San Francisco, CA. and has an office in Cambridge, MA.

What you'll do: Collections & Accounts Receivable

- Own and actively manage AR and collections as a core day-to-day responsibility, including billing and invoicing, monitoring AR aging, driving customer follow-up, resolving overdue balances and payment issues, and ensuring timely cash application.
- Drive improvements in cash collection and AR performance by establishing effective collection cadences, tracking key metrics, and partnering closely with Sales and Customer Success to resolve disputes and accelerate payment.
- Be accountable for AR performance, including DSO, aging by bucket, past-due balances, and cash forecast accuracy, reported regularly to Finance leadership.
- Build direct relationships with customer AP and procurement contacts to resolve billing questions, portal and PO issues, and payment blockers before they delay cash.
- Establish credit and collections policies, including customer credit review, payment terms, hold and escalation criteria, and bad debt reserve methodology.
- Automate collections workflows with AI and AR tooling, including dunning sequences, invoice delivery and portal submission, and payment reminders.

Accounts Payable & Purchasing

- Own the overall AP and purchasing function, including the strategy, systems, processes, and controls needed to scale with the business.
- Partner closely with the Staff Accountant, who runs point on day-to-day AP processing; provide reviewer-level oversight of invoice coding, approvals, payment runs, vendor setup, and 1099 compliance.
- Build and improve scalable purchasing controls and workflows, including vendor onboarding, PO requesting, open PO management, and purchase accruals.
- Lead the transition from Teampay to Ramp and own Ramp's buildout across bill pay, purchasing, approval workflows, virtual cards, and vendor management.
- Own and continuously improve Ramp and its integration with NetSuite, including workflows, GL mappings, automation, troubleshooting, and ensuring complete and accurate data flow into the GL.

Systems & AI

- Own maintenance of AP systems (Ramp), AR/Revenue systems (currently Maxio), Sales Tax (Avalara), and their integrations to NetSuite.
- Leverage AI tools, including Claude, to turn recurring work (contract and invoice review, coding, reconciliations, flux analysis, audit support) into documented, reusable workflows with appropriate review points and controls.

Revenue & Sales Tax

- Own monthly revenue recognition under ASC 606, including contract review, revenue schedules, deferred revenue roll-forwards, and related reporting.
- Own sales tax reporting and compliance, including coordination with third-party tax providers and resolution of sales tax issues.
