I’m Scott - founder of DoStuff. We have a pretty big, and growing, membership product called DoMORE - $7/month for a pair of tickets to an event we think you’ll like. We’re hiring a hands-on Retention Product Engineer to own engagement → churn reduction end-to-end.

You will analyze cohorts, define the retention north-star metric, ship product and lifecycle experiments yourself, and measure impact.

This is not a PM-only role and not a pure engineering role. You own the full loop: insight → build → measure → iterate.

Our stack: React (FE), Ruby on Rails + Elixir (BE), Postgres, Elasticsearch. Proprietary lifecycle tooling for email, SMS, and in-app (web). No feature-flagging or experimentation framework yet - you’ll help install the remaining plumbing.

Retention is the highest-impact opportunity in the business and this role has real authority to ship.

If you have experience with the above and this sounds like fun, reach out to scott+domore@dostuffmedia.com with something in the subject line that let’s me know you’re real and interested. THX
