Senior Product Manager

3i Members•New York City, NY

About The Position

3i is hiring its first Senior Product Manager to own the full product lifecycle – strategy, roadmap, and execution – behind 3i's digital member platform. This role requires both modes simultaneously. You'll set the product vision and run the sprint. You'll define what 3i should be in three years and ship the feature next week. The ideal candidate is energized by both – someone who finds the strategy hollow without shipping it, and the execution meaningless without a point of view driving it. You'll manage a lean team of two engineers, build our product operating system, and serve as the connective tissue between what happens across business lines (deals, events, network) and what members experience digitally. Reports to the Co-Founder. Full-time in New York City.

Requirements

5+ years in product, ideally coming out of a PM role – we want someone still close to the work
Experience building 0 to 1 products that reached scale; ideally in marketplaces, community, or high trust consumer platforms
Design sensibility – you know what separates great products from mediocre ones, and your work shows it
Fluent in both modes: you can write a product strategy doc and a clean PRD in the same week
You create structure where none exists and move without waiting for perfect information

Responsibilities

Define the product strategy: what 3i's platform should be, how it creates member value, and how it compounds as we scale
Partner with senior leadership on translating business priorities into a coherent, sequenced product roadmap
Oversee and maintain the roadmap – prioritize ruthlessly, balance short- and long-term investments, defend sequencing, and adjust when reality changes
Own the complete digital journey across web, mobile, and every touchpoint, spanning deals, events, network, and peer interaction surfaces
Ground every product decision in member insight: what they do, what they need, and where the platform is losing them
Lead 3i's AI product strategy – identify where AI can meaningfully enhance the member experience and enable the team to do more with less
Run the full product development cycle: discovery, spec, build, QA, launch
Own product documentation: specs, decisions, post-mortems, and institutional knowledge
Establish product rituals – sprint planning, reviews, retros – that drive high velocity without sacrificing craft
Launch an intuitive, intelligent mobile app with social feeds, real-time notifications, and peer discovery
Manage two engineers, hire our first Product Designer, partner with fractional CTO on technical strategy, define and track success metrics
Partner with business line owners across deals, events, and network to translate their needs into product solutions – you'll manage competing priorities, align expectations, and serve as the bridge between what the business needs and what gets built
