Email Developer - Maropost / ESP Migration

About the Role 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. This is execution-focused work on a tight timeline (build complete before late-August UAT, September launch). What You'll Do • Build and deploy ~100 transactional and lifecycle emails in Maropost — order confirmations, shipping notifications, refunds, cancellations, account updates, abandoned cart, welcome/onboarding, reorder flows, product review requests, and promotional campaigns • 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 You're a Strong Fit If You Have • 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) Bonus Points For • 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 Engagement Details • 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
