Staff Product Marketing Manager, Integration Stack and Developer Ecosystem

BILL is a rapidly growing Fintech company focused on empowering businesses through innovative financial tools. The Staff Product Marketing Manager will own the go-to-market strategy for the integration stack and developer ecosystem, influencing product roadmap and driving commercial outcomes.

Responsibilities:

• Build a deep, defensible understanding of developer and buyer audiences across this ecosystem: their jobs-to-be-done, segmentation, and personas. Synthesize customer, competitor, and market signal into a clear point of view and introduce the persona-led practices that keep cross-functional teams grounded in market reality
• Serve as the voice of the market in product planning. Use your point of view to influence the quarterly and annual roadmap, weigh in on go/no-go and beta-exit decisions, and surface the market opportunities worth building toward
• Develop differentiated positioning and messaging for BILL's API, developer, and integration offerings. Tailor it to each audience, lead positioning work with cross-functional stakeholders, and maintain a living competitive view of how other developer ecosystems and embedded-finance players position themselves
• Own end-to-end go-to-market for new API capabilities, platform features, and partner integrations. Coordinate messaging, timing, channels, and cross-functional readiness across Product, Developer Relations, Marketing, and Sales. Define and track launch metrics including developer activation, time-to-first-call, integration attach, and partner-influenced pipeline
• Build the developer and integration marketing programs that attract, activate, and retain developers and customers across the funnel. Own the supply-side narrative for why partners build on BILL. Develop pricing and packaging points of view to share with the Pricing team
• Build repeatable, scalable sales enablement for the field: pitch narratives, battlecards, objection-handling guides, and discovery frameworks for platform and embedded-finance conversations, with segment-specific messaging for each buyer
• Run win/loss analysis on platform and partner deals and translate findings into sharper positioning. Partner with the accounting-firm channel so advisors can advocate for BILL's embedded capabilities. Own the commercial outcomes for the domain

Requirements:

• 8+ years of B2B product marketing experience, including 3+ years marketing a platform, API, developer ecosystem, or embedded/infrastructure product
• Strong customer and market research instincts: the ability to synthesize qualitative and quantitative signal into a differentiated point of view, defend it with cross-functional partners, and use it to influence the product roadmap
• A track record of building and owning go-to-market programs for technical products with developer or platform-builder audiences, including end-to-end launches from brief through post-launch measurement
• Demonstrated ability to develop positioning and messaging that works across developer, technical buyer, finance buyer, and partner-channel audiences for the same underlying product
• Experience building sales enablement that field teams actually use, and a history of operating at a senior IC level: driving ambiguous initiatives and reconciling conflicting priorities without formal authority
• Background in fintech, payments, financial infrastructure, or enterprise software, with fluency in payment workflows, AP/AR processes, and financial-data compliance requirements
• Direct experience marketing a two-sided platform or marketplace, covering both the developer or partner supply side and the end-customer demand side, including partner-influenced pipeline tracking
• Familiarity with AI-agent ecosystems and LLM tool integration, either as a marketer or hands-on practitioner, with a working understanding of how agentic workflows are reshaping software distribution
• Experience at a company distributing through embedded or API-first channels (embedded payments, banking-as-a-service, white-labeled infrastructure), or close proximity to accounting, ERP, or SMB financial-technology companies
