About the role

This role sits at the intersection of product, data, and customer communication.
The work here is both strategic and deeply technical.
The growth pod is lean and expects a lot from each PM.

Buying and selling fashion feels simple, joyful, and personal, while every item tells its own story.
You will own Poshmark's marketing technology stack, including our customer engagement platform (CEP), customer data platform (CDP), email, push notifications, promotional systems, and CRM strategy for our merchandising and seller teams.
The common thread is that you own the infrastructure and the outcomes, not just the roadmap.
You will own the product strategy for how to scale and use it.
Build and refine audience segmentation strategy across buyer lifecycle stages and seller engagement tiers
Partner with data engineering to ensure audience definitions are accurate, refreshable, and auditable
Own the roadmap for how we expand CDP usage over time, including new activation use cases across email, push, and paid channels
You will own the product strategy across all three, setting standards for message quality, channel coordination, experimentation, and performance.
Lead personalization initiatives including our ML-powered delivery timing program, working closely with data science on model inputs, evaluation, and rollout
Establish standards for how the team builds, tests, and iterates on campaigns within the platform so quality is consistent and learnings compound

4+ years in a product management or growth engineering role with direct ownership of a martech stack
Hands-on experience with a customer engagement platform (MoEngage, Braze, Iterable, Salesforce Marketing Cloud, or similar) at a product or implementation level, not just a user level

Experience at a consumer marketplace with active seller and buyer communication programs (Etsy, eBay, Whatnot, Depop, or similar)
Background in email deliverability: domain reputation, list hygiene, ISP relationships, and inbox placement
Prior work on AI-driven personalization systems, recommendation-based messaging, or predictive audience models
Experience integrating a composable CDP (Hightouch, Segment, or similar) with a downstream engagement platform
Comfortable reading API documentation, reviewing data schemas, and holding a technical conversation with engineers and data scientists as a peer
Track record of running structured experiments across owned channels with proper methodology: experiment sizing, holdout groups, attribution, and incremental lift measurement
Experience working with incrementality measurement frameworks is a plus
If email open rates drop or push opt-outs spike, you are the first to diagnose and address the problem

Set the standard for email and push quality and deliverability health, partnering with engineering and marketing ops to monitor performance and resolve issues quickly
