What you'll be doing

Financial Planning & Analysis

• Own revenue reporting and P&L analysis to provide leadership with clear visibility into financial performance
• Build and maintain financial models for scenario planning, annual budgeting, and leadership presentations (hiring plans, cash burn, growth scenarios)
• Coordinate month-end close, expenses, and payroll processing with external partners (accountants, tax)
• Manage client invoicing and cash collection processes

Revenue Operations

• Design revenue performance dashboards tracking pipeline health, conversion rates, and sales velocity
• Own revenue forecasting models and continuously improve prediction accuracy
• Configure and optimize commercial tools (CRM, deal desk, quoting systems) and roll out scalable GTM processes

• Detail-oriented with a strong financial discipline: ensuring accuracy in all financial reporting and operations.
• A collaborative partner who communicates well across departments.
• Motivated by tangible impact: you care about helping the company scale efficiently and intelligently.

Who you're not

• You're not just a numbers person; you understand the business context and strategic implications behind the data.
• You don't wait for playbooks; you write them.
• You're not intimidated by technical tools, financial systems, or CRM integrations.
• You don't avoid tough conversations about financial accountability or operational efficiency.
• You're not satisfied with keeping the status quo - you continuously seek optimization.

Requirements

• Demonstrated experience with revenue operations projects (sales process, CRM implementation, sales compensation or revenue reporting)
• Strong proficiency in financial modeling, revenue reporting, and P&L management
• Excellent communication and cross-functional collaboration skills
• Experience supporting SaaS business models and understanding of recurring revenue metrics

Nice to have
