This role involves building and shipping user-facing experiences for a multi-channel messaging platform, focusing on SMS, email, and emerging channels for top Ecommerce brands. As an experienced individual contributor, you will leverage deep technical expertise and product sense to deliver polished, performant user experiences using React and TypeScript.

Trusted by more than 18,000 Shopify and Shopify Plus stores—like Brooklinen, Ruggable, True Classic and Dr. Squatch—Postscript gives ecommerce brands the tools they need to run a world-class SMS marketing program.

We’re on a mission to make SMS the number-one revenue channel for ecommerce merchants by delivering an easy-to-use platform where they can grow their subscriber list, develop and test their messaging strategy, deliver excellent customer service, and drive sales and loyalty—all in one place. We believe SMS is the most important marketing and sales channel of the decade, and that vision drives everything we do.

Postscript was founded in 2018 as a 100% remote organization. With more than 250 employees (and counting!), we’re backed by Greylock, Y Combinator, and other top investors.

As Senior Frontend Engineer for the Messaging Channels team at Postscript, you will build and ship the user-facing experiences that power our multi-channel messaging platform, enabling top Ecommerce brands to reach their customers across SMS, email, and emerging channels.

Senior Engineers at Postscript are experienced individual contributors who take ownership of significant frontend features and systems. They combine deep technical expertise with strong product sense to deliver polished, performant user experiences.
