Interim Controller - Boulder in Boulder, Colorado at Ascent CFO Solutions

Location: Boulder, CO (Hybrid — Tues/Wed/Thurs in-office; remote considered for exceptional AdTech/MarTech candidates)
Engagement Length: ~6 months
Target Start Date: Mid-to-late July
Compensation: $90-95/hour (W2 or 1099)

Our client, a growing AdTech company based in Boulder, CO, is seeking an experienced Interim Controller to provide critical coverage during a maternity leave transition. This is a hands-on, execution-focused role for someone who thrives on ownership and can step into an established process with minimal ramp-up.

This is not a strategic CFO-level position - it's a "get it done" role for someone who wants to lead a lean, capable team and independently own the monthly close.

The current Controller is transitioning out for a 16-week leave, with the interim Controller assuming full responsibility by the end of July. The Interim Controller will lead a lean team consisting of a Staff Accounting and Contract Senior Accountant.

What You'll Do:

• Independently own the full close process: a 5-day flash close (cash/AR/revenue) and a 9-day full close
• Manage Revenue Recognition in a high-volume transactional environment
• Oversee accounting for internally developed software assets
• Handle GL entries related to payroll
• Execute monthly/quarterly commission and bonus processes
• Lead and support a lean accounting team through a transition period
• Partner closely with the CFO on day-to-day accounting operations

Experience & Technical Skills

• Background in AdTech, MarTech, or similar high-volume transactional tech environments
• Strong technical accounting skills, particularly Revenue Recognition
• Proven ability to independently manage a close process from start to finish
• Experience with payroll-related GL entries and commission/bonus cycles

Systems

• NetSuite required
• Experience with any of the following is a plus: Looker, FloQast, CaptivateIQ (commissions/bonuses — a big plus), Expensify, Tipalti, Spendflow, Concur

Soft Skills & Culture Fit

• High personal agency — able to drive tasks to completion with minimal oversight
• Strong critical thinking — proactively flags issues and asks the right questions before problems compound
• Accountability — owns mistakes and adapts quickly
• Communication style that's direct, objective, and low-drama — matches a CFO who is laid-back but highly direct
