• Experience managing or upgrading agency or vendor partners.
• Comfort with AI-enabled workflow in daily tasks.
• Self-starter who can operate from a blank slate and fill gaps.

Responsibilities

• Build the testing program from scratch, including A/B tests and holdouts tied to incrementality.
• Reconcile Klaviyo and Shopify attribution to produce trusted numbers.
• Take over agency management and bring more work in-house over time.
• Partner with brand, creative, product, and growth to shape the full customer journey.
• Help define and evolve the retention strategy as the function matures.

Job description

A fast-growing consumer tech brand with a physical device and app that help people reclaim their attention from their phones. It's 9-figure revenue, profitable, has been featured in the NYT and Washington Post, and only hires the best when it comes to leadership.

The opportunity

Email and SMS are agency-run today, on a 1.5M+ contact Klaviyo database. This is the company's first in-house lifecycle owner: you'll take the function over, build it, and eventually grow the team around you.

What you'll do

• Own email and SMS end-to-end: campaigns, flows, segmentation, calendar, QA, and reporting in Klaviyo
• Build the testing program from scratch: A/B tests, segment tests, and holdouts tied to incrementality
• Reconcile Klaviyo and Shopify attribution so the team can trust the numbers
• Take over agency management, then bring more of the work in-house
• Partner with brand, creative, product, and growth on the full customer journey, not just the inbox
• Help shape the retention strategy
• Stay hands‑on at the start, with more strategy as the function matures

What you bring

• Deep hands‑on Klaviyo experience and a proven track record in DTC or subscription lifecycle
• A rigorous approach to testing and measurement, beyond "we ran a test"
• Strong email and design judgment, and the ability to raise the creative bar
• Experience managing or upgrading agency or vendor partners
• Daily AI fluency in your workflow
• A scrappy, self‑starter mindset. You're comfortable operating from a blank slate and stepping outside your job description to fill gaps.
• Clear communication and real excitement for the mission

Why this seat

• Build a lifecycle program from zero instead of inheriting one
• Own the retention story in the company's next phase of growth
• Work with a leadership team that moves fast and cares about the mission
• Grow with the function, with a clear path to Director
