For more information about our firm, please visit https://www.castroconceptsllc.com/. About the Role: We’re looking for a Senior Finance Consultant to join our team—someone who can step in as a trusted partner to our clients and an extension of our internal team. This role is designed for a finance leader who is equally comfortable operating at the CFO, Director, and Controller levels, depending on client needs. Some engagements will be highly strategic, while others will require rolling up your sleeves and getting into the details. You’ll lead client relationships, oversee and support accounting work, and collaborate closely with the Founder to continue building and growing the firm. This is a great fit for someone who enjoys variety, ownership, and meaningful, mission-driven work. Key Responsibilities: Client Leadership & Advisory

• Serve as the primary finance lead for assigned clients, acting as a Fractional CFO or senior finance partner
• Provide strategic guidance around budgeting, forecasting, cash flow, and financial planning
• Translate financial data into clear, actionable insights for leadership teams and boards
• Support clients through key moments such as growth phases, transitions, and system improvements

Financial Operations & Oversight

• Oversee and, when needed, directly support accounting functions including month-end close, reconciliations, and financial reporting
• Ensure accuracy, completeness, and alignment with GAAP and best practices
• Review work prepared by accounting team members and provide feedback and guidance
• Step into Controller- or Director-level responsibilities depending on the engagement

Team Collaboration

• Provide mentorship and support to other team members
• Help ensure consistency and quality across client work
• Contribute to a collaborative, supportive, and accountable team environment

Firm Growth & Partnership

• Partner closely with the Founder on client strategy, internal processes, and service delivery
• Support business development efforts as needed (e.g., scoping, proposals, client conversations)
• Play an active role in shaping the future growth of the firm

Qualifications:

• 8+ years of progressive experience in nonprofit accounting and finance
• Experience operating in a CFO, Finance Director, or Controller capacity (or similar consulting experience)
• Strong technical accounting skills and knowledge of U.S. GAAP
• Ability to move between strategic thinking and detailed execution with ease
• Experience with accounting systems (e.g., QuickBooks, Xero, NetSuite, Sage)
• Strong communication skills and ability to work directly with non-financial stakeholders
• Highly organized, detail-oriented, and accountable
• Comfortable working independently in a remote, client-facing environment
• Experience working with mission-driven organizations

What We’re Looking For

• Someone who takes ownership and can confidently lead client relationships
• A “player-coach” who is just as comfortable in the details as they are in strategy
• A thoughtful, collaborative partner who aligns with our values: Authenticity. Partnership. Equity. Impact.
• Someone with high emotional intelligence and discretion
• Someone who is excited to grow with a boutique firm over time
• And just as important: someone who enjoys the work, likes to laugh, and values building genuine relationships with both clients and teammates

Interview Process: We value transparency and respect for candidates’ time. Our interview process is designed to be thoughtful, conversational, and efficient. The process will include:

• Application and resume review
• Initial 20–30 minute introductory conversation with the Founder
• One 45–60 minute panel interview with members of the Castro Concepts team
• Follow-up conversations and/or references as needed

Because this is a highly relational, client-facing role, we place significant value on communication style, collaboration, and alignment with our firm values. Compensation & Proposal Information: This is an independent contractor (1099) role. Interested candidates are encouraged to share their preferred hourly or project-based rates, availability, and any additional information that may help us better understand their consulting approach and areas of expertise. Engagement scope and hours may vary based on client needs, areas of specialization, and overall fit. We are looking for a long-term partner who is excited to grow alongside the firm as engagement opportunities continue to evolve. Benefits & Opportunity: This is an independent contractor role and not eligible for traditional benefits. However, we offer:

• Flexible, fully remote work
• The opportunity to work with mission-driven organizations making real impact
• Variety in client work and exposure to different industries and growth stages
• A collaborative, values-driven team environment
• The ability to grow alongside a scaling firm and expand your role over time

If you’re looking for meaningful, engaging work and want to be part of a team that truly partners with its clients, we’d love to hear from you! Application Question(s):

• Do you have nonprofit finance experience?
