Finance Engineer (Rotational Program)

About the role:

Lumafield is hiring a Finance Engineer into a three-year rotational program across Finance & Accounting. A Finance Engineer is a finance professional who wires systems together, builds AI agents and workflows, then uses them to own real analysis, close work, and operations.

Program overview:

• Three one-year rotations: FP&A (reporting to the Head of Finance), Finance Operations, and Record-to-Report (both reporting to the Head of Accounting).
• A readout to Finance leadership at the end of each rotation covering what you owned, what you built, and what the next Finance Engineer inherits.
• Rotation managers give structured feedback at the midpoint and end of each year.
• On completing the third rotation you graduate into a senior role in Finance, Accounting, or another Lumafield team that needs an AI builder with finance judgment.

The working rule on this team:

If you do something twice, write a workflow; if you write the workflow twice, write an agent. The stack you will build on includes NetSuite, Maxio, Ramp, Numeric, HubSpot, Abacum, Databricks, and Claude. Each rotation adds domain context, so after three years you have analytical, modeling, AI building, and AI orchestration skills and broad context across Finance, Accounting, and Lumafield's business and operations.

What you'll do:

• Own the analysis, modeling, and deliverables for your area, and be accountable for their accuracy and timing.
• Write skills and apps building on our data lake and source systems rather than waiting on engineering or exporting to spreadsheets.
• Connect systems and remove workflow bottlenecks: integrations, GL mappings, data flows, and the controls around them.
• Build and orchestrate AI agents and workflows for the team, with documented review points so the output is audit-ready.
• Turn recurring work into documented, reusable workflows that the next Finance Engineer can run and improve.

Rotation 1: FP&A

• Own the operating model and forecast in Abacum, including headcount, revenue, cash, and runway, and the monthly variance analysis against plan.
• Build the board and executive reporting package: ARR, backlog, bookings, deployments, liquidity, and OpEx trends.
• Support capital markets and M&A work: data rooms, diligence requests, scenario modeling, and lender compliance reporting.
• Build the forecasting and reporting agents that keep these packages current without manual rebuilds.

Rotation 2: Finance Operations

• Own collections and accounts receivable performance: aging, DSO, cash application, and customer AP portal resolution.
• Own accounts payable and purchasing in Ramp, including approval workflows, vendor management, and the NetSuite integration.
• Own monthly revenue recognition under ASC 606 and sales tax compliance in Maxio and Avalara.
• Automate collections, billing, coding, and reconciliation workflows with AI tooling and measure the cash impact.
• Own inflows and outflow forecasting of 13 week cash forecast

Rotation 3: Record-to-Report

• Run the month-end close for your areas, including balance sheet reconciliations, flux analysis, and audit-ready workpapers.
• Own inventory, COGS, fixed assets, and manufacturing cost accounting for our scanner production.
• Serve as a primary contact for external auditors on the areas you own and maintain the related process and control documentation.
• Build close agents that draft entries, reconciliations, and flux explanations for human review.

About you:

• Agile: comfortable rotating into a new area every year and adapting as the team, systems, and priorities change.
• Demonstrated Judgment: makes sound calls with incomplete information and knows when to escalate.
• Builder mindset: wires systems together, writes skills and workflow automation, and prototypes rather than waiting for someone else to do it.
• AI fluency: proficient in tools such as Claude and has shipped working workflows or agents with them.
• Clear communicator and writer; documentation and workpapers can be picked up by someone else.
• Attention to detail: numbers tie, workpapers stand up to audit, and errors are caught before they leave the team.
• Continuous improvement mindset: treats every recurring task as a process to shorten, document, or automate.
• High degree of ownership: takes an area end to end, from the first question to the posted entry, and is accountable for its accuracy and timing.
• Bachelor's degree in Accounting, Finance, Economics, Engineering, or a quantitative field; MBA or CPA a plus.
• 2 to 6 years work experience in finance, accounting, FP&A, finance systems, analytics, or a technical role that touched any of these.

Bonus:

• CPA or MBA (a plus, not a requirement).
• Familiarity with SQL
• NetSuite, Ramp, Maxio, Abacum, or Databricks experience.
• Experience in a hardware, manufacturing, or mixed hardware/software business.
