Email Marketing Developer

We're migrating an established ecommerce client from Mandrill to Maropost as part of a broader Shopify replatform. We have designers and strategy covered — the gap is a hands-on email developer who can take designs and turn them into production-ready, logic-driven templates inside Maropost.

You'll own the build-out of roughly 100 transactional and lifecycle marketing emails: Liquid-based templates, modular components, conditional logic for complex user segments, multi-country/multi-language support, and Shopify trigger integration. You'll also help audit and migrate existing Mandrill flows.

Develop a reusable, modular component library plus a global header/footer system aligned with the client's new design system

Implement Liquid-based dynamic templates with conditional logic for variables like customer type (e.g., preferred customer vs. unaffiliated buyer), autoship vs. non-autoship, affiliate flows, subscription lifecycle events, and lead routing

Configure multi-country and multi-language localization

Audit the client's existing Mandrill email inventory and migrate flows to Maropost (or support a hybrid approach if needed)

Wire up Shopify triggers to Maropost flows; validate end-to-end functionality alongside the broader platform migration

Coordinate with subscription tooling (Seal Subscriptions) for subscription-related email events

Support a dedicated QA phase covering business logic variability, localization, deliverability, and rendering across major clients and devices

Document templates, components, and conditional logic so the client's marketing team can maintain and extend the system post-launch

Requirements

3+ years of hands-on email development experience with production builds inside an ESP

Direct Maropost experience strongly preferred. Will consider experienced developers from Klaviyo, Iterable, Braze, Customer.io, Salesforce Marketing Cloud, or similar platforms if you can ramp quickly

Prior experience executing an ESP migration, ideally Mandrill another platform

Strong command of Liquid templating (or comparable ESP templating languages)

Expert-level HTML/CSS for email: tables, inline styles, MSO conditional comments, dark mode handling, and responsive techniques that survive Outlook

Experience integrating an ESP with Shopify (or comparable ecommerce platform), including event-triggered transactional flows

Comfort translating Figma designs into pixel-faithful production templates

High attention to detail around conditional logic, edge cases, and localization variants

Familiarity with email QA tooling (Litmus, Email on Acid, or similar)

Nice to have:

Maropost certifications or shippable Maropost portfolio work

Subscription / autoship email flow experience (Seal Subscriptions, ReCharge, Skio, etc.)

Multi-language / multi-country email programs at scale

Deliverability fundamentals (SPF, DKIM, DMARC, sender reputation, suppression management)

Working on migration timelines tied to a larger replatform launch

Benefits

Type: Contract, with potential to extend into post-launch optimization and remaining marketing campaigns

Duration: ~2 months of active build; target completion before late-August UAT for a September launch

Commitment: Full-time preferred; 30+ hours/week minimum

Location: Remote
