Lifecycle Marketing Manager, Sleeper

• 3-5 years in lifecycle, CRM, or growth marketing, with meaningful ownership of a consumer program
• Deep hands-on Braze experience (or comparable: Iterable, Airship, Customer.io) — you've built multi-step, branching journeys yourself, not just briefed them
• Strong grasp of email deliverability — sender reputation, authentication, and engagement-based sending. Bonus if you've personally run a domain warm-up or deliverability recovery
• Analytically rigorous. Comfortable in the data, designing holdouts, and telling incremental lift from correlation
• A builder's bias. You're energized by a blank slate and can go from strategy to shipped without waiting for a team
• Clear writer. You can write a push notification that gets tapped and an email that gets opened
• Collaborative with product and engineering — you can scope an instrumentation ask and see it through

Desirable

• Sleeper is where millions of sports fans play fantasy, make picks, and follow the games together. We've built a product people love — and now we're building the lifecycle program to match it
• This is a rare zero-to-one role, embedded directly with our product team. Every automated journey — onboarding, activation, retention, win-back — is yours to design and build. You'll own the strategy and the execution, from segmentation logic to the copy that ships
• You'll sit with product because lifecycle is product here: the moments that matter happen in the app, and your work shapes how users discover, adopt, and stick with what we build
• Build out and optimize our lifecycle program in Braze — canvases for onboarding, activation, retention, and reactivation across push, email, and in-app
• Strengthen email as a channel. Own email deliverability end to end: domain warm-up, list hygiene, and engagement-based sending
• Own segmentation and targeting. Define audiences from behavioral data, and partner with data and engineering to get the events and attributes you need instrumented
• Run real experiments. Holdouts, incrementality, and A/B tests — measure lift, not vanity metrics
• Drive lifecycle for tentpole moments — season kickoffs, competitions, and product launches — partnering closely with PMs, design, and marketing
• Set the operating standards: naming conventions, QA, frequency capping, and how we decide what's worth sending
• You won't be optimizing someone else's program — you'll be defining ours. High autonomy, a direct line to the product team, and measurable impact on activation, retention, and revenue
