Job description

Controller | Early Stage Physical AI Company | Fully Remote (US)

The Client

Harmonic is partnering with an early stage business building the software layer for physical AI.

The company is the clear leader in its category, and is shipping new products into a market that is expanding underneath it. This is the first Controller hire, being brought in to build the accounting function as they scale.

The Role

Reporting to the CFO, the Controller owns accounting end to end: close, technical accounting, controls, audit, and tax. You inherit a small team and a revenue model that runs from self-serve subscriptions through usage-based consumption to multi-year enterprise agreements, which makes revenue recognition the most interesting problem in the function. The first twelve months are about turning a startup accounting operation into something that holds up under Series C diligence: a close that lands on a predictable calendar, a documented control environment, a clean audit, and numbers the board can rely on without caveats. This is a hands‑on role with genuine build scope, not a maintenance seat.

Key Responsibilities

• Own the monthly and quarterly close end to end, including consolidation and reconciliations, and deliver accurate US GAAP financials on a defined timetable.
• Lead revenue recognition under ASC 606 across self-serve, usage-based, and enterprise contracts, owning the policy, technical memos, and supporting systems.
• Build and document the control environment: policies, approval thresholds, segregation of duties, and audit-ready support.
• Manage the external audit as principal point of contact, from planning through to signed accounts.
• Own technical accounting across equity and stock compensation, capitalized software, leases, and any new areas the product roadmap creates.
• Manage federal, state, and international tax compliance and sales tax nexus alongside external advisors.
• Run AP, payroll accounting, and treasury operations, and upgrade the systems stack so the close scales without adding headcount.
• Line manage and develop the accounting team, and partner with FP&A, RevOps, and Legal on pricing and contracting before commercial decisions become accounting problems.
• CPA strongly preferred, ideally with a grounding in public accounting or a technical accounting function.
• Controller, Assistant Controller, or equivalent accounting leadership experience in a venture‑backed technology business.
• Deep working knowledge of ASC 606, ideally across more than one revenue model.
• Experience owning an external audit and building the control environment that makes it possible.
• Track record of shortening close cycles and improving accounting systems, not simply operating what already exists.
• Comfortable in a business where the product, pricing, and revenue model are all still moving.
• Experience in a product‑led business where self‑serve and enterprise revenue sit side by side.
• Exposure to a Series B, C, D or later raise, or institutional diligence.
• Big 4 or national firm training.
• NetSuite, plus a modern billing or revenue automation tool.
