About the Role

We're looking for a Product Manager to lead the development and launch of a mobile app. This is a 0-to-1 product role where you'll own the full product lifecycle from scoping to execution while collaborating closely with a major mobile carrier's in-house development studio. You’ll be responsible for delivering an app that connects users to the Sei ecosystem, including wallet functionality, ecosystem discovery, and gamified experiences. This role requires fluency in both Mandarin and English and is based in NYC or APAC.

Responsibilities

• Own the end-to-end product lifecycle for a mobile app, from v1 through future iterations

• Define the product roadmap, manage prioritization, and lead execution in collaboration with internal teams and external development partners

• Manage relationships with external engineering partners to ensure alignment, delivery, and quality

• Drive key features such as wallet integration, ecosystem discovery, in-app incentives, and gamification

• Deliver weekly milestones toward major launches (v1, v2, v3) and track progress

• Optimize for user adoption and engagement, with success metrics focused on WAUs (Weekly Active Users)

• Serve as the connective tissue between the Sei team, the mobile carrier, and the development studio

What we're looking for

• Proven experience shipping 0-to-1 mobile products and managing external development partnerships

• Bilingual in Mandarin and English, with excellent communication skills in both

• Background in either big consumer tech (e.g., Meta, Snap, YouTube, Instagram) or crypto-native apps (e.g., Coinbase, Binance, Robinhood)

• Familiarity with mobile wallet products, gamification, or ecosystem-driven apps

• Ability to thrive in an autonomous environment and operate like a founder: scrappy, resourceful, and execution-focused

Nice to haves

• Experience in DePIN, passive crypto apps (e.g., Pi, Grass), or superapp environments

• Previous founder or early-stage startup experience

• Understanding of mobile wallet security and user onboarding best practices

• Design intuition or previous work directly influencing UX/UI decisions
