About the Role:
We are seeking a Principal Engineer, Mobile who combines deep technical mastery with hands-on leadership. You will own the architectural evolution and strategic technical direction of our native mobile apps-defining how we build, scale, and deliver world-class experiences for millions of users.
As the most senior technical leader for mobile, you will partner closely with senior engineering, product, and design leaders to craft a best-in-class experience for millions of customers, while mentoring the next generation of technical leaders.
This role is both strategic and hands-on: you'll design and prototype core frameworks, guide critical architectural decisions, and mentor teams in engineering excellence. You'll influence the long-term technical direction for iOS and Android while contributing directly to the most complex, high-impact initiatives across the mobile ecosystem.
You Will:
• Define and evolve the architectural vision for our native mobile platforms (iOS and Android), ensuring scalability, performance, and reliability across the entire mobile ecosystem.
• Lead by example-prototype, code, review PRs, and shape engineering standards that elevate quality across the org.
• Partner cross-functionally with Product, Design, Data, and Platform teams to align technical roadmaps with customer and business goals.
• Establish frameworks and standards that ensure engineering excellence-covering modularity, observability, CI/CD, release safety, and operational resilience.
• Drive architectural modernization efforts-modularization, performance optimization, offline capabilities, and dependency management.
• 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.
You Have:
• 15+ years of software engineering experience, with deep expertise in native mobile engineering (Swift, Kotlin, Android SDK, iOS frameworks, ReactNative).
• Proven track record of architecting and delivering mobile applications at scale, including complex, distributed consumer systems.
• Experience shaping cross-platform strategies (React Native, Kotlin Multiplatform, or similar) a strong plus.
• Strong understanding of app architecture patterns, mobile CI/CD pipelines, and observability practices.
• Demonstrated ability to drive technical strategy and lead cross-team initiatives that span multiple disciplines and product areas.
• Deep knowledge of system performance, reliability, and mobile UX principles.
• Strong business acumen-able to connect technical decisions to customer and company outcomes.
• Exceptional collaboration and communication skills, with experience influencing across functions and leadership levels.
• A passion for mentoring and growing technical talent, fostering excellence through coaching and exemplars.
• Bachelor's or Master's degree in Computer Science, Engineering, or a related field (or equivalent experience).
What You'll Bring to the Org
• Vision for how mobile systems, architecture, and teams scale together sustainably.
• Deep empathy for both the end-user experience and the engineer experience.
• The ability to simplify complex systems and make bold, pragmatic technical decisions that accelerate delivery.
• A track record of shaping mobile architectures that drive measurable business impact
• Balance long-term architectural vision with pragmatic, iterative delivery.
• Care deeply about system resilience, developer experience, and customer reliability.
• Are motivated by complexity and thrive in high-impact, cross-functional environments.
Our Benefits (there are more but here are some highlights):
• Competitive salary & equity compensation for full-time roles
• Unlimited PTO, company holidays, and quarterly mental health days
• Comprehensive health benefits including medical, dental & vision, and parental leave
• Employee Stock Purchase Program (ESPP)
• 401k benefits with employer matching contribution
• Offsite team retreats
We are committed to building a workforce that reflects diverse perspectives and prioritizes ethics, wellness, and a strong sense of belonging. If you're excited about this role, we encourage you to apply-even if you're not sure if your background or experience is a perfect match.
