Job description

Great River Group (GRG) is seeking an FP&A Manager to support the finance function across its geotechnical engineering platform; a group of multiple standalone entities operating under a shared holding company structure. This is a true 0-to-1 role. We are not hiring someone to inherit an established FP&A function or delegate the work to an existing team, read: there are no existing SOPs or processes to take over; you are building them. This person will be responsible for building the FP&A capability across the platform, getting into the data, understanding how the businesses operate, building the reporting and forecasting infrastructure, and creating processes that can ultimately scale.

Beyond traditional FP&A work, this role plays a central part in our top initiative: building a consolidated, holding-company view of financial data across multiple operating companies. You'll also help modernize and streamline accounting processes, manage key banking and card-account relationships, and be a trusted partner to decision-makers who rely on your numbers to guide real business decisions.

Key Responsibilities

Multi-Entity Data Aggregation & Reporting

• Lead the aggregation of financial and operational data across multiple operating companies into a unified, holding-company-level view.
• Build and maintain consolidated reporting structures (P&L, balance sheet, cash flow, KPIs) that roll up cleanly from entity-level detail to platform-level insight.
• Partner with entity controllers and accounting teams to standardize chart of accounts, reporting cadence, and data definitions across the platform.
• Build the initial FP&A reporting infrastructure rather than simply administering an existing reporting process.

Data Integrity & Analysis

• Treat data integrity as non-negotiable — dig into root causes of variances rather than accepting numbers at face value.
• Proactively question data sources, reconciliations, and reporting logic to catch errors before they reach leadership.
• Develop and maintain financial models (forecasting, budgeting, scenario/sensitivity analysis) grounded in clean, validated data.

Accounting Efficiency & Modern Process Design

• Assist the Corporate Controller in identifying opportunities to streamline and modernize accounting workflows across entities— automation, system integration, and process standardization.
• Bring a point of view on how modern tools (ERP systems, automation, reporting platforms) can reduce manual work and improve close timelines.
• Support accounting leadership in evaluating and implementing efficiency initiatives across the platform's shared services.

Business Partnering & Executive Reporting

• Prepare and present key company metrics and KPIs to decision-makers on a weekly and monthly basis.
• Translate financial data into clear, actionable insight that helps leaders make meaningful operating decisions — not just report the past, but inform what's next.
• Build strong working relationships with entity leaders, Corporate Controller, and FP&A/accounting teams across the platform.
• This role is intentionally located in an operating company environment. We believe proximity to the business is important to understanding the numbers, building relationships, and becoming a trusted partner to operating leaders. This is not intended to be a traditional fully remote FP&A role.

What We're Looking For

• Bachelor's degree in Finance, Accounting, or a related field.
• 8–10+ years of progressive finance/accounting experience gained within a company (industry/operating company background)
• Solid working knowledge of accounting principles and close processes — enough to be a credible partner to accounting teams and to help design more efficient processes.
• Advanced Excel and financial modeling skills; experience with modern ERP/reporting systems (e.g., Acumatica, NetSuite, PowerBI, or similar)
• Experience working across multiple entities, business units, or a holding-company/platform structure is a strong plus.
• Naturally self-sufficient: comfortable owning ambiguous problems, driving them to resolution, and knowing when to ask for input versus when to run with it.
• A curious, questioning mindset — someone who instinctively traces a number back to its source rather than passing it along at face value.
• Strong communication skills, with the confidence and clarity to present financial results and recommendations directly to senior leaders.
• Demonstrated alignment with GRC and GRG's values is an important part of the selection process. We are looking for someone who demonstrates integrity and trust, puts people and relationships first, takes ownership and shows grit, thinks critically and challenges ideas respectfully, is emotionally aware, provides high-quality service to internal and external customers, and works collaboratively across companies and functions.
• Most importantly, we are looking for someone who enjoys building. This person should be energized by ambiguity, comfortable starting with an imperfect process, and willing to personally do the work required to build something better.

Work Arrangement

This is a U.S.-based position located in a GRC/GRG operating company office, with approximately 2–3 days of travel per month to other company locations for in-person collaboration, planning sessions, and reporting reviews. We believe being close to the business is important for this role.
