# Senior Product Manager at Co–Star

- **Company:** Co–Star
- **Location:** New York, NY
- **Work type:** remote
- **Posted:** 2026-10-26

- **Apply:** https://job-boards.greenhouse.io/costar/jobs/6234758004

## Job description

Co–Star is hiring a Product Manager.

Most of the products we build don’t have obvious precedents. We need someone who can help the team navigate that uncertainty and turn ambitious ideas into products people actually use.

You’ll work closely with design, engineering, and content throughout the product development process, using tools like Claude Code to prototype concepts. You’ll help shape what we build next, keep the team focused, and move projects from early ideation to launch.

## What you’ll do

- Own major product initiatives, from defining the problem through launch and iteration.
- Partner closely with design and engineering from early exploration through launch.
- Write product requirements, set priorities, and keep projects moving.
- Facilitate planning, reviews, and communication across the team.
- Help the team make informed decisions through user research, data, experiments, and using Co–Star deeply yourself.
- Go deep on important product questions when needed, whether that means conducting user research, designing experiments, or working through a difficult tradeoff.
- Help the team decide what matters most and make smart calls about quality, scope, and speed.
- Have a hand in where the product goes next, not just how we get there.

You might be a fit if

- You’re roughly 7+ years in, and you’ve spent that time building consumer software people love to use.
- You know how to create structure without weighing a team down.
- You’re as comfortable writing a spec as you are talking to users or reviewing a prototype.
- You can work from a half-formed idea and help it find its shape.
- You have a point of view, but care more about getting the product right than being right.
- Claude Code and Cursor are part of your workflow.
- Work > ego

## What we offer

- Fully covered $0 deductible healthcare + vision, dental, and therapy
- 401(k) + 5% matching
- Unlimited vacation + 2-week company-wide recharge at the end of each year
- Equipment budget
- 12 weeks 100% paid parental leave

Logistics

- Full-time. New York preferred.
- Compensation: 180k–220k + benefits
