Justworks is seeking a Senior Product Marketing Manager, Growth to own strategy and execution across the customer lifecycle—from acquisition through expansion. This role sits at the intersection of product marketing and growth, directly impacting funnel conversion, net revenue retention, and customer lifetime value.
You will design and optimize customer journeys across both self-serve and sales-assisted motions, translating ICP definitions into entry points, progression paths, and conversion strategies. You'll partner with Product, Growth Marketing, Revenue, and Sales teams to prioritize growth opportunities, define how customers expand across the platform, and build frameworks that guide investment decisions.
Key responsibilities include:
• Own strategy and messaging across the full customer lifecycle—acquisition (first touch through conversion and activation) and expansion (multi-product adoption)—reducing time-to-value and time-to-expansion.
• Design lifecycle stages, behavioral triggers, and journey blueprints that shape customer progression, and partner with Pricing & Packaging to reinforce positioning at key conversion moments.
• Partner cross-functionally to design and prioritize growth strategies, focusing on acquisition efficiency, conversion velocity, and expansion revenue. Serve as business owner for your funnel area: set goals, track performance, and communicate results to leadership.
• Define and prioritize experimentation hypotheses across your funnel area. Maintain an experimentation roadmap with prioritized tests, learnings, and optimization recommendations. Operate with a test-and-learn mentality, moving fast on data and applying learnings iteratively.
• Track key metrics: funnel conversion rates by stage and segment, CAC efficiency, time-to-value, self-serve share, ARPC, NRR, add-on attach rate, and lifecycle progression rates.
• Develop deep expertise on the SMB buyer through continuous qualitative and quantitative research. Partner with Market Intelligence on voice of customer, win/loss, and competitive research, translating insights into journey design and targeting decisions.
• Influence cross-functional stakeholders—Sales, Revenue Operations, Demand Generation, Product, and fellow PMMs—without direct authority. Build trust through clarity, rigor, and follow-through.
The role emphasizes customer obsession, analytical rigor, and a hacker's mentality for finding growth. You'll work in a supportive, entrepreneurial environment aligned around shared values: Camaraderie, Openness, Grit, Integrity, and Simplicity.
QUALIFICATIONS:
• Minimum 6 years in product marketing, growth marketing, or related B2B SaaS function, with track record of owning funnel strategy and driving measurable outcomes.
• Outstanding storyteller who synthesizes customer, market, and data signals into clear narratives for different audiences (prospects to senior leadership).
• Data-driven with customer empathy; combine intuition with rigorous analysis and regularly conduct customer interviews, sales calls, and win/loss reviews.
• Deep familiarity with hybrid self-serve and sales-assisted GTM motions; SMB buyer experience strongly preferred.
• Fluent in key metrics: funnel conversion rates, CAC efficiency, time-to-value, NRR, ARPC, and lifecycle progression rates.
• Proven ability to influence cross-functional stakeholders without direct authority.
• Ownership mentality; scrappy and resourceful in fast-moving, ambiguous environments.
• Experience in HR tech, fintech, payroll, or adjacent SMB platforms is a plus.
