Product Marketing Manager - Product Growth

B-Stock•Boston, MA

17h•$120,000 - $145,000•Hybrid

About The Position

As a Product Marketing Manager, you will build B-Stock’s product growth function, which is a critical area focused on feature adoption, platform engagement, and the buyer behaviors that drive marketplace liquidity. This role is a direct response to B-Stock’s platform evolution, bridging product development and marketing to ensure buyers discover, adopt, and deepen their engagement with the platform. This role is complementary to Lifecycle Marketing, which owns overall buyer funnel health (acquisition, activation, retention). Where Lifecycle Marketing focuses on whether enough buyers are activating and returning, Product Growth focuses on whether buyers are finding and using features that make them stickier. You will work closely with Lifecycle Marketing, briefing them on feature launches and surfacing behavioral signals for them to act on, while maintaining a clear lane around feature adoption and platform engagement depth. You will serve as a primary connector between Marketing, Product, and Analytics—translating buyer behavior data into roadmap input and translating product decisions into buyer-facing messaging and go-to-market programs. You will proactively manage marketing projects, coordinate execution across teams, and be accountable for delivering measurable outcomes.

Requirements

4+ years of product marketing, growth marketing, or closely related experience, ideally in a B2B marketplace, SaaS, or e-commerce environment.
Demonstrated track record of launching product features and driving measurable adoption outcomes—you define the metrics, own the GTM, and report on results.
Strong data fluency: you can generate hypotheses, structure an analytical approach, and make evidence-based decisions; experience working directly with Analytics or Data teams is a plus.
Cross-functional collaboration skills with Product and Engineering teams in an agile environment.
Experience briefing a lifecycle, CRM, or demand generation team on product-driven campaigns.
Excellent written communication—you can translate complex platform behavior into crisp, buyer-centric messaging and equally clear internal briefs.
High standards for your own work; you proactively identify the most important problems.
Familiarity with tools such as Salesforce, Amplitude, Jira, Braze, or similar CRM/analytics platforms.
Experience with landing page optimization or conversion rate experimentation.
Work Authorization required.

Nice To Haves

A background in marketplace businesses, recommerce, wholesale, or supply chain-adjacent industries.
Exposure to SEO/AEO content strategy as it relates to product discovery.

Responsibilities

Proactively identify the most important problems to solve across the buyer product experience; define goals for product growth that align with company-wide marketing initiatives.
Own the Go-To-Market (GTM) strategy and launch execution for buyer-facing features (e.g., saved search, delivery preferences, customer preferences); define adoption metrics and hold yourself accountable for delivering against them.
Develop and maintain a product growth roadmap—a prioritized view of GTM initiatives and adoption programs—and align stakeholders in Product, Analytics, and Lifecycle Marketing around it.
Work through roadblocks with minimal guidance; set high standards for the quality and impact of your work.
Develop a deep understanding of B-Stock’s buyer segments, how they shop, and what drives repeat platform engagement.
Build and maintain buyer personas that capture behavioral patterns and feature usage to sharpen product positioning and campaign briefs.
Brief Lifecycle Marketing on feature launches with clear audience targeting rationale, key messages, and behavioral triggers.
Generate hypotheses about buyer behavior and feature adoption to structure a logical analytical approach and identify needed data.
Partner with Analytics to define shared measurement frameworks (e.g., aligning on definitions for “activated” or “engaged”) and build visibility into feature adoption metrics.
Demonstrate strong quantitative and qualitative judgment in decision-making—pull reports, interpret cohort analyses, and make evidence-based recommendations independently.
Track post-launch performance for every feature GTM; surface insights back to Product and Analytics with clear recommendations.
Serve as a buyer marketing partner to the Product team by participating in sprint reviews and roadmap planning, synthesizing behavioral data, and advocating for buyer-facing improvements.
Co-own the measurement infrastructure for product growth with Analytics, including aligning on definitions, building dashboards, and identifying instrumentation gaps.
Maintain clear and productive handoffs with Lifecycle Marketing: provide the brief (what to promote, to whom, and why), with Lifecycle owning channel execution (including in-app messaging).
Share behavioral signals from product data with Lifecycle Marketing for targeting, reactivation, and retention programs.
Collaborate and communicate effectively across Marketing, Product, and Analytics in service of shared goals; attend sprint reviews and product forums to build trust with Product and Engineering partners.
