About the role

We are looking for a sharp, fast, brand-obsessed Retention Specialist to own the voice of a high-growth consumer technology client. You will write the email and SMS copy that carries the program, direct the creative that goes with it, and keep the marketing calendar moving as output scales.

You are writing a program into existence rather than maintaining one. The list starts near 20,000 and grows fast behind a significant acquisition investment, volume ramps to 40-60 emails a month, and deepening segmentation multiplies the number of versions behind every send. Most of what you write is automated - lead capture, welcome series, first-conversion and activation sequences - and then loyalty and repeat purchase programming on top of it. The program runs on enterprise tooling such as Braze, Salesforce Marketing Cloud, Iterable, or Customer.io.

This is a copy-led role. You will write more than you manage, and the quality of your writing is the primary thing we are hiring for. The ability to hold a consistent voice across a lot of output is essential.

A day in the life

• Write the email and SMS copy for campaigns, flows, and automations across your client's program, from lead capture through activation, loyalty, and repeat purchase.

• Develop and maintain the client's marketing calendar, sequencing campaigns against the strategy your Associate Director sets and flagging capacity risks before they become problems.

• Write creative briefs for the design team and give clear, specific direction on what each asset needs to do.

• Review and approve designs in Figma, leaving actionable feedback and shepherding assets to final.

• Own the brand voice and the copy guidelines for your client, keeping tone consistent as output scales and segmentation multiplies the number of versions.

• Partner with the CRM Specialist to make sure copy, segmentation logic, and dynamic content line up in the build.

• Proof every send before it goes out - copy, links, personalization, rendering.

• Review performance with your Associate Director and translate what you learn into your next round of copy tests.

You are a copywriter who happens to work in lifecycle marketing. You can explain a technical product simply, write a subject line that earns the open, and make a subscription upgrade feel like a good idea rather than a sales pitch.
