Lifecycle Marketing Manager

Lifecycle Program Manager

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.

What You'll Do

• 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.

What We're Looking For

• 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.

Bonus Points

• Experience with in-app messaging and push, not just email

• Experience in — or genuine passion/curiosity for — sports, fantasy, DFS, gaming, or another real-money/regulated consumer product

• Familiarity with responsible-gaming or compliance-aware messaging

• SQL, and comfort working directly with a data warehouse

• You're a sports fan who actually uses products like ours

Why This Role

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.
