• Contribute to the codebase for critical paths and architectural exemplars—setting the tone for craftsmanship, quality, and velocity.

• Drive cross-org initiatives that unify app architecture, component libraries, and shared services—balancing platform consistency with team autonomy.

• Shape mobile technical strategy, influencing native (Swift, Kotlin) and hybrid (React Native) approaches with a pragmatic, future-oriented mindset.

• Mentor senior engineers and tech leads, raising the overall bar for system design, operational excellence, and customer empathy.

• Champion mobile performance, reliability, and quality—building systems that anticipate scaling challenges, minimize app size, and ensure best-in-class user experiences.

• Lead through ambiguity by identifying high-impact problems, clarifying ownership, and creating frameworks that drive momentum across teams.

• Represent Mobile Engineering in company-wide architectural forums, ensuring mobile’s voice shapes Hims & Hers’ broader technical evolution.

• Foster a culture of innovation and excellence, embedding principles of craftsmanship, experimentation, and continuous learning into the mobile organization.

• Influence company-wide architecture by representing mobile in cross-platform technical strategy discussions.
