Senior Product Manager, Grantseeker

Fluxx is looking for a strategic, systems-thinking Senior Product Manager to own and evolve our Grantseeker platform. This role is a great fit for someone coming from FinTech. If you've built products that move money securely and compliantly, you'll find a natural home here, helping funds reach the organizations doing mission-driven work.

We are looking for people who are curious, tenacious, candid, and have a bias toward action. We welcome diverse perspectives and encourage you to apply if you think you can bring value to our team, even if your experience doesn’t perfectly match the job description.

Grantseeker was originally launched by Fluxx in 2017 to help nonprofits manage the grantseeking process—a market traditionally underserved by grants management software. After serving more than 3,000 nonprofits, the platform was strategically divested in 2023, rebuilt as Grantseeker Pro for larger nonprofit and public sector organizations, and re-acquired by Fluxx in November 2025.

Today, Grantseeker helps nonprofits, higher education institutions, and government organizations manage grant portfolios, deadlines, budgets, reporting, documents, and compliance in one platform. Combined with Fluxx Grantmaker, it delivers a complete end-to-end solution for organizations that both award and receive grants.

This role owns Grantseeker's product direction at a genuine inflection point - having been re-acquired by Fluxx. Grantseeker has real traction, a durable data asset, and a newly dedicated product and engineering team — and it also has a two-platform architecture to reconcile, a free-to-paid conversion motion to sharpen, and an unrealized strategic advantage in being the only grantseeker platform owned by a major grantmaker platform.

You will be the person who decides what Grantseeker becomes over the next several years. This is a builder's role, not a caretaker's.

• 8+ years in software PM with real revenue ownership of a B2B SaaS product.
• Direct product-led growth experience: freemium tiers, self-serve onboarding, activation/retention instrumentation.
• A track record of hard prioritization calls — including saying no with reasons attached.
• Genuine data fluency; you build your own funnel views rather than outsourcing your understanding of the numbers.
• Strong written communication (specs, memos, decision records) and experience shipping in tight, iterative cycles with design and engineering.
• Comfort with ambiguity and an early-team environment.

• Domain experience in grants management, nonprofit technology, fundraising or development operations, higher ed research administration, or public sector grant compliance.
• Experience consolidating multiple products or codebases onto a single platform, including customer migration.
• Experience with competitive displacement and migration tooling.
• Applied AI/ML product work, especially search, matching, recommendation, or document generation.
• Multi-sided platform or marketplace experience.
• Background working with or inside a nonprofit, foundation, or grantmaking institution.
• Experience building or managing FinTech products, particularly in payments, treasury management, financial transactions, or regulatory compliance.
• Experience developing secure, compliant financial workflows involving money movement, transaction processing, or financial data.

Fluxx is committed to fair, transparent, and equitable compensation practices. We use a market based approach that considers cost of labor by geographic region, along with company size and industry benchmarks.
