About this role

About the Role We're hiring an Email Marketing Automation Developer to join Rhythm's Lifecycle Marketing Platform team and help power the customer journeys that drive acquisition, engagement, retention, and winback. This is a highly hands-on technical role focused on building, maintaining, and troubleshooting email and SMS automations in Iterable. You'll work closely with our Marketing Platform Manager as her primary technical partner, taking ownership of journey execution, template development, quality assurance, and platform operations across multiple Iterable instances.

This isn't a marketing strategy role. We're looking for someone who enjoys getting into the details—building complex automations, troubleshooting technical issues, optimizing deliverability, and ensuring every customer journey works exactly as intended. As our agency support winds down, you'll play a critical role in bringing this capability fully in-house and helping establish a scalable lifecycle marketing platform.

What You'll Do Marketing Automation & Journey Development Build, maintain, and optimize email and SMS customer journeys using Iterable's workflow builder. Develop and troubleshoot complex, multi-step automations, including branching logic, wait conditions, audience filters, re-entry rules, and cross-channel messaging. Configure new Iterable projects, sending domains, and sender profiles as needed. Manage audience segmentation, suppression lists, frequency caps, and compliance workflows across multiple Iterable instances.

Template Development & Technical Operations Build and maintain highly dynamic email templates using Handlebars, including conditional logic, loops, data feeds, and fallback handling. Read and modify HTML and CSS to support email template development and troubleshooting. Investigate and resolve technical issues such as failed sends, broken triggers, stale drafts, and audience discrepancies without relying on engineering support.

Support IP and domain warmup activities by building rollout schedules, monitoring deliverability metrics, and adjusting sending strategies. Quality Assurance & Platform Support Own campaign QA, including pre-send validation, render testing, link testing, and journey verification. Partner with the Marketing Platform Manager to set up A/B tests and support performance reporting. Support customer surveys, including Qualtrics setup, Iterable distribution, monitoring, and reporting.
