Full Job Description
đź“‹ Description
- • As the Lifecycle Growth Lead at Sei Foundation, you will be the architect of our user journey, meticulously crafting and executing strategies that foster deep engagement and lasting loyalty from the very first interaction through to sustained, habitual usage. This pivotal role sits at the intersection of product, marketing, and data, ensuring that every user's experience with Sei is optimized for growth and retention.
- • Pre-launch, your primary mission will be to cultivate a vibrant and engaged waitlist. This involves developing and implementing sophisticated nurturing strategies. You will design and deploy compelling email sequences that educate, excite, and build anticipation. You'll establish engaging loops that encourage ongoing interaction and create powerful referral mechanics to organically expand our community of early adopters. A key part of this phase is building robust segmentation models, leveraging data from signup sources, early behavioral signals, and depth of engagement to tailor communications and maximize impact.
- • Your expertise will be crucial in designing and executing a flawless launch-day activation sequence. The goal here is to convert our enthusiastic waitlist into actively participating users from day one, minimizing any friction and maximizing immediate value realization. You will be responsible for instrumenting and rigorously tracking key waitlist health metrics, including open rates, click-through rates, referral rates, and crucially, churn from the list, allowing for rapid iteration and optimization.
- • Post-launch, your focus shifts to driving sustained user engagement, retention, and maximizing lifetime value (LTV). You will own the end-to-end lifecycle marketing efforts across multiple channels, including email, push notifications, in-app messaging, and SMS. This requires a deep understanding of user behavior and a strategic approach to communication.
- • You will design and implement sophisticated lifecycle campaigns that are intrinsically tied to key user milestones. Whether it's a user's first transaction, their completion of their first week, or identifying windows for reactivation, your campaigns will be designed to reinforce positive behaviors and re-engage dormant users.
- • A significant aspect of your role will involve building and optimizing behavioral nudge systems. These systems will deliver the right message, through the right channel, at the precise moment a user is most receptive, guiding them towards their next desired action and deepening their engagement with the Sei ecosystem.
- • You will act as a crucial partner to the product team, proactively identifying points of user drop-off within the product journey and collaborating to design and implement effective interventions. This cross-functional collaboration is essential for creating a seamless and rewarding user experience.
- • Continuous improvement is at the heart of this role. You will be responsible for running constant A/B tests across various elements of your campaigns – including messaging, timing, channel selection, and sequencing – to identify what resonates best with our users and drives the most impactful results.
- • Finally, you will be the primary owner of reporting on key growth and retention metrics. This includes cohort retention analysis, tracking LTV trends over time, and providing detailed performance reports for all campaign-level activities, ensuring transparency and data-driven decision-making across the organization.
- • This role offers a unique opportunity to shape the growth trajectory of a groundbreaking Layer 1 blockchain, directly impacting user acquisition, engagement, and long-term value. You will be instrumental in defining the user experience for a platform poised to set new standards in Web3 performance and scalability.
