Role Description Now we're looking for a Staff Mobile Engineer to serve as a technical leader and contributor for our mobile code that powers our connected sleep ecosystem. You'll be a leader on engineering development for our mobile apps, specifically the iOS and Android apps that keep millions of devices humming in real homes. You’re a great fit if you thrive in environments of rapid learning and delivery. You’re self-motivated and have demonstrated strong ownership and self-direction. You strive to understand the business of what we are trying to accomplish and push engineering solutions to provide customer value. As a small company where AI-assisted development is core to how we work, we expect this role to ramp up quickly, use AI fluently in their day-to-day, and deliver broadly across our mobile systems. Working across Mobile, and partnering closely with Product, you'll lead feature development, set technical direction, and mentor engineers. What You'll Do - First 90 Days: Learn & Contribute - Review existing codebase and identify immediate technical improvements. - Ship meaningful code to production and begin to establish credibility with the engineering team. - First 6 Months: Drive Real Impact - Technical Leadership: Lead delivery of features, and jump into production issues or improvements, debug cross-platform problems spanning mobile/firmware/backend. - Cross-Pillar Ramp: Build context on how the full mobile platform fits together. Contribute meaningfully to your team’s initiatives — shipping features, improving platform reliability, and driving daily app engagement. - Architectural Ownership: Understand problem spaces, partner with stakeholders to shape architectural problems and solutions, and bring proposals to Mobile Strategy and Engineering Forum meetings. - Engineer Mentorship: Provide feedback and support for other engineers. - Cross-functional Collaboration: Work closely with Product, Design, QA, and other stakeholders to scope, plan, and rapidly ship features. - AI Integration: Champion AI-assisted development practices within your team — not just using the tools yourself, but creating the conditions where others adopt them faster and go deeper. - First Year: Transform & Scale - Strategic Impact: Drive business strategy through mobile initiatives and shape the roadmap across the mobile organization — contributing to decisions that benefit all pillars and the people who use Hatch every night. - Raise the AI Bar: Serve as a critical evaluator and implementor of our AI strategy. Help define what "good" looks like so that as new engineers join, there's a standard to onboard into, not just an assumption. Qualifications - Deep Mobile Craft: You’ve spent 6+ years building mobile apps that matter—whether in Swift/SwiftUI or Kotlin/Jetpack Compose. You care about code quality, reliability, and making great experiences for real people. - Technical Leadership: You love leading by example—writing production code, unblocking others, leading architectural decision-making, and helping teams make smart, pragmatic decisions. You’re as comfortable setting direction as you are rolling up your sleeves. - Mentorship: You believe great teams make great products. You’ve mentored other engineers, built trust, and created environments where people do their best work. - Collaborative Energy: You thrive in cross-functional spaces—partnering with Product, Design, and other engineering leaders to turn ideas into reality. You communicate clearly and lead with empathy. - AI Curiosity: You’re genuinely excited about what AI unlocks—how it can make us more effective builders and open new ways to serve our customers. - Broad Technical Reach: You bring experience with modern mobile tooling, CI/CD, testing, and cloud services—and you’re always eager to explore new technologies, tech stacks, and approaches. Benefits - 100% paid medical, dental, and vision insurance for employees (80% for dependents, including domestic partners). - Meaningful equity — you’re an owner here. - 401(k) match (no vesting schedule!). - 16 weeks of fully paid parental leave. - 16 free therapy sessions (for you + one other adult in your life). - Financial support for family planning. - Remote office + monthly internet reimbursement. - Friends & family discounts on Hatch products. - Exclusive discounts on travel, entertainment, and top retail brands. - And so many more spontaneous perks!
