Sr. Associate, Global Engagement Marketing

Responsibilities

• Build, QA, schedule, and launch email and SMS campaigns in Klaviyo, with a high bar for accuracy, formatting, links, segmentation, compliance, and customer experience.
• Own the day-to-day campaign development process, helping turn briefs, calendars, product priorities, and creative assets into clear, shippable owned-channel communications.
• Support the Harry’s global engagement calendar across key moments including product launches, seasonal campaigns, promotional moments, retention initiatives, and winback efforts.
• Partner with the Global Engagement Lead and Brand Managers to translate business priorities into compelling email and SMS storytelling that is clear, customer-centered, and commercially effective.
• Coordinate closely with Creative, Brand, Digital Product, Analytics, Growth, CX, Legal, and other partners to keep campaigns moving and ensure the right inputs are gathered on time.
• Help improve the way we work by identifying opportunities to make campaign planning, buildout, QA, documentation, templates, and reporting more efficient and repeatable.
• Monitor campaign performance and customer behavior, pulling insights from Klaviyo and analytics partners to understand what is working and where we should test or improve.
• Support lifecycle and flow updates as needed, including building and QA’ing triggered communications, testing personalization, and helping maintain a clean, high-quality customer journey.

Requirements

• You are highly comfortable in CRM tools, ideally Klaviyo, and are energized by the detailed work of building, QA’ing, and launching emails and SMS messages.
• You have experience supporting email, SMS, CRM, lifecycle, retention, or ecommerce marketing campaigns, ideally for a consumer brand or subscription business.
• You are detail-oriented and operationally strong, with the patience to manage tedious buildout work and the judgment to know when small details materially affect the customer experience.
• You care about copy, storytelling, and how a message lands with a customer, not just whether a campaign gets out the door.
• You are curious about strategy and performance, and want to grow into more ownership of audience planning, testing, segmentation, and campaign recommendations over time.
• You are comfortable using data to understand campaign performance, spot trends, and suggest practical optimizations.
• You are a proactive communicator who can manage dependencies across teams, raise risks early, and keep work moving without needing every step prescribed.
• You are organized, collaborative, and comfortable working with global teammates across time zones, including reporting to a manager based in the UK.
• You are customer-centric, with a strong instinct for making owned-channel communications feel useful, clear, and worth engaging with.
