Postscript is the AI messaging platform trusted by 20,000+ Shopify brands — including Brooklinen, Ruggable, True Classic, and Dr. Squatch.
With a mission to make SMS your number one revenue driving channel, we built the best-in-class SMS marketing platform and launched revenue-driving AI features not available on any other platform. And we're just getting started.
Backed by Greylock and Y Combinator, fully remote since 2018.
Postscript is looking for a Principal CSM to serve as our subject matter expert and internal champion for one of our newest product lines. This is not a traditional CSM role — it sits at the intersection of customer success, enablement, and program development. You'll operate as a strategic overlay across a focused book of business while also doing the foundational work of building what a great customer journey looks like for this new offering.
This is a fully remote position that can be based in the US or Canada.
You'll carry a book of business while simultaneously building the playbooks and enablement materials that will scale what you learn to the broader CSM team. The right person has been a strong CSM, but has also led programs, built assets others use, and influenced strategy beyond their own accounts.
