Finance Controller

Banyan Infrastructure is a project finance software platform purpose-built for green and climate infrastructure deal teams, lenders, and fund managers. The platform provides a unified workflow and data layer that replaces fragmented tools such as Salesforce, Monday.com, and Excel, enabling organizations to manage the full lifecycle of infrastructure deals — from origination and underwriting through portfolio management and compliance reporting. Its customers include owner-operators, developers, infrastructure funds, project financiers, green banks, and community funds. The company's mission is closely tied to accelerating the deployment of sustainable and climate-focused infrastructure by removing the operational friction that slows down green finance. By centralizing deal pipelines, due diligence processes, covenant tracking, and portfolio risk monitoring in a single platform, Banyan Infrastructure helps climate-focused financiers close deals faster and scale their portfolios without proportional increases in headcount. What makes Banyan Infrastructure distinctive is its deep focus on the project finance niche within the green economy, offering tools specifically designed for the complex reporting, compliance, and covenant management requirements of infrastructure lending and investment. The platform creates audit-ready submission records and provides real-time KPI alerts, allowing teams to proactively identify at-risk investments and stay ahead of stakeholder obligations.

The Role

We are hiring a Finance Controller to lead Banyan’s accounting foundation and help build a strong finance function as the company scales. This role reports to the Head of Operations, partners closely with the CEO, and works closely with the leadership team across accounting, planning, budgeting, cash management, and operating discipline.

This is a strategic, hands-on role for someone who enjoys building structure, improving rigor, and partnering across the business. The right candidate brings strong accounting judgment, startup pragmatism, and the ambition to grow with the organization over time. While this role includes FP&A responsibilities, the center of gravity is controllership, accounting accuracy, and financial operating discipline.

What You Will Do

• Lead Banyan’s core accounting and controller functions, including monthly close, reconciliations, financial reporting, and related controls.
• Own the integrity of the general ledger and ensure timely, accurate financial statements and supporting schedules.
• Manage day-to-day finance operations across AP, AR, payroll coordination, accruals, expense management, and cash tracking.
• Help build and improve finance processes, policies, internal controls, and reporting discipline appropriate for a scaling company.
• Partner with the Head of Operations, CEO, and leadership team on budgeting, forecasting, runway planning, and financial visibility.
• Support FP&A activities, including annual planning, periodic forecasts, variance analysis, and management reporting.
• Prepare materials and analysis to support board reporting, investor discussions, and key operating reviews.
• Manage external partners across tax, audit, bookkeeping, and other finance-related service providers as needed.
• Partner cross-functionally with operations, people, go-to-market, and product leaders to improve financial rigor and decision-making across the business.
• Own and manage the tools and systems to support Banyan’s FinOps function
• Build toward a more mature finance function as the company grows in complexity, team size, and investor scrutiny.

What We Are Looking For

• 5-8 years of experience in accounting, finance, controllership, or related roles.
• Strong grounding in accounting fundamentals, with experience owning or materially contributing to close and financial reporting processes.
• Experience in startup, high-growth, or similarly fast-moving environments where systems and processes are still being built.
• Working knowledge of budgeting, forecasting, and core FP&A practices.
• Strong spreadsheet and financial modeling skills, with comfort working directly in the details.
• Sound judgment, attention to detail, and a high bar for accuracy, accountability, and follow-through.
• Strong communication and collaboration skills, with the ability to work effectively with senior leaders and cross-functional peers.
• A startup mindset: pragmatic, collaborative, resourceful, and comfortable moving between strategy and execution.
• CPA, public accounting background is strongly preferred; significant startup controllership experience may substitute.
•  SaaS / fintech / infrastructure experience is a plus

What Success Looks Like

In this role, success means building a stronger finance function, increasing confidence in Banyan’s financial reporting and planning, improving operating discipline, and giving the leadership team clearer visibility into performance, cash, and business trends. This person should be equally comfortable owning the details, improving the process, and helping the company make better decisions as it scales.

Why Join Banyan

You will help shape how Banyan operates, how the finance function evolves, and how the company scales with discipline. This role will play an integral part in establishing the financial foundation to support Banyan’s next fundraise milestone. This is an opportunity to take on meaningful ownership in a growing company that values collaboration, execution, and practical problem solving.

Location
