About the Role

We are looking for a Senior Product Manager to join our Growth product team. You'll own the product strategy for growth, spanning acquisition, activation, monetization, and retention - working closely with engineering, design, marketing, and data to move the metrics that matter most. Our current PM team is small and agile, and we're looking for someone who brings a rigorous, experimental mindset and is energized by finding leverage in the funnel.

Responsibilities

• Define and drive the growth product strategy and roadmap, with clear ownership over top-of-funnel, activation, conversion, and retention metrics.
• Design, run, and analyze A/B and multivariate experiments across the product to identify high-impact growth levers and rapidly iterate on findings.
• Collaborate with engineering and design to build and optimize growth-oriented product surfaces — including onboarding flows, in-product upsell and upgrade moments, referral mechanics, and pricing page experiences.
• Partner closely with marketing, revenue operations, and sales to align on the full customer journey, from first touch to paid conversion and expansion.
• Develop a deep understanding of user behavior through quantitative analysis and qualitative research, and use those insights to prioritize the growth roadmap.
• Own growth metrics including signups, activation rate, trial-to-paid conversion, time-to-value, and net revenue retention, and report on progress regularly to leadership.
• Build and maintain a healthy experimentation pipeline, balancing quick wins with longer-term bets that compound over time.

Qualifications

• 5+ years of product management experience, with at least 2 years in a dedicated growth, lifecycle, or monetization role.
• Demonstrated track record of moving growth metrics — acquisition, activation, conversion, or retention — through product-led experimentation.
• Strong quantitative skills; comfortable with funnel analysis, cohort analysis, statistical significance, and tools like Amplitude, Mixpanel, or similar.
• Experience designing and running A/B tests end-to-end, including hypothesis formation, instrumentation, analysis, and rollout decisions.
• Deep understanding of PLG (product-led growth) motions and how to design self-serve experiences that reduce friction and accelerate time-to-value.
• Excellent communication skills with the ability to align marketing, sales, and product around a shared growth narrative.
• Proven ability to work cross-functionally and lead in a fast-paced, agile environment.

Nice to Haves

• Experience working with AI-powered products, particularly optimizing onboarding or activation for technically novel tools.
• Familiarity with legaltech, compliance, or B2B SaaS industries where the buyer and end user are often different people.
• Experience with pricing and packaging strategy, including freemium, trial, or seat-based monetization models.
• Background in growth engineering, data science, or marketing — having worn more than one hat is a plus.
