The Opportunity

This is the first dedicated Revenue Operations hire in Mainspring’s history. We’re commercializing the linear generator — a breakthrough technology that converts a wide range of fuels directly into electricity — with a growing fleet of deployed systems and strong commercial traction.

You won’t be stepping into a defined lane. You’ll own the full quote-to-cash cycle, bring the technical accounting rigor our complex revenue streams demand, and build the processes that carry us through our next phase of growth. You’ll report directly to the VP of Finance and Controller, sit at the center of our most critical financial workflows, and have a front-row seat to everything ahead of us.

This is a role for someone who wants real ownership — not a process to maintain, but a function to build. If you’re technically sharp, hungry to make an impact, and motivated by meaningful work at a company solving a real energy challenge, read on.

### What You'll Own

Revenue recognition (ASC 606): Lead recognition analysis for all contracts — multi-element arrangements, milestone payments, third-party financing overlays. Document and defend positions with the Controller and external auditors.

Invoicing & billing: Drive the full cycle across equipment sales, LTSAs, O&M contracts, and project engagements. Own the Salesforce-to-NetSuite handoff — and improve it.

Accounts receivable & collections: Manage the AR ledger end-to-end: aging, cash application, collections, reconciliation, and KPI reporting to Finance leadership.

Project accounting & advances: Track revenue, cost, and margin by project. Manage customer advance payments from receipt through milestone-based revenue release.

Project finance support: Maintain billing and AR records in support of lender reporting, covenant compliance, and financing due diligence.

Sales tax compliance: Own multi-jurisdiction tax determination, exemption certificates, and coordination with external tax advisors.

Process improvement: This is where you leave your mark. Automate, streamline, and build the SOPs and system integrations that scale with the business.

### Who You Are

You have deep, practical experience in revenue accounting or revenue operations — and you’ve been in the room when ASC 606 questions get complicated. You’ve managed billing tied to milestones, navigated financing overlays, and answered an auditor’s question without needing to check with anyone first. Just as important: you see the current manual workflow and want to fix it, not just run it.
