About the Role
The Principal Software Engineer, Mobile is SharkNinja's deepest technical authority on mobile engineering — the person others come to when the patterns don't exist yet. You'll define the architectural standards and engineering principles that shape mobile across SharkNinja's connected product ecosystem, including SharkClean, NinjaPro Connect, and the next-generation unified app platform.
You'll tackle the most complex technical challenges at the intersection of mobile, firmware, cloud, AI, and consumer experience — exercising independent judgment on high-stakes, ambiguous decisions with long-term implications.
This is an IC role. Your authority comes from expertise and trust, not headcount.
What You'll Own
Solve the Hardest Technical Problems
Own SharkNinja's most complex, non-recurring mobile challenges — spanning native iOS/Android, cross-platform frameworks, cloud integration, device connectivity, and AI-driven development.
Make and defend high-stakes architecture and technology decisions with long-term impact on platform reliability and engineering velocity.
Define Technical Standards and Architecture
Set and evolve mobile engineering standards — architecture patterns, cross-platform strategy, testing philosophy, and production-readiness criteria.
Define integration patterns across mobile, cloud, firmware, and connected devices, and drive React Native vs. native platform strategy.
Evaluate emerging technologies and AI coding tools, forming clear technical points of view.
Lead Technical Thought Leadership
Serve as SharkNinja's go-to authority on mobile engineering across Mobile, Firmware, Cloud, Hardware, Product, and Design.
Lead design reviews and communities of practice that raise engineering quality org-wide.
Elevate Engineering Capability
Mentor senior and staff engineers through proximity to hard problems.
Build reusable frameworks, reference architectures, and documentation that outlast any single project.
Champion AI-driven development workflows across the mobile org.
Advance AI-Ready Mobile Architecture
Define how the mobile platform integrates with AI — on-device inference, AI-powered features, and data contracts connecting mobile to cloud-based AI services.
Solve mobile/AI integration challenges with no established playbook, ensuring the platform is built for the AI-powered features SharkNinja will ship next.
What You'll Bring
12+ years of progressive software engineering experience, with deep expertise in native iOS (Swift), Android (Kotlin), and React Native.
A track record of solving the hardest mobile engineering problems — architecture, cross-platform unification, consumer-scale reliability — with measurable impact at scale.
Deep expertise in mobile-to-cloud integration, BLE/Wi-Fi connectivity, and the full stack from firmware interfaces through cloud services.
Recognized technical authority, sought out when the stakes are highest.
Proven ability to set engineering standards and frameworks that scale across teams.
Strong cross-functional influence built on technical credibility, not positional authority.
Excellent written and verbal communication, translating complex decisions for leadership and business stakeholders.
Preferred: Rust/C/C++ for cross-platform or performance-critical work; connected product/IoT/robotics/smart home background; AI-integrated mobile architecture experience (on-device ML, AI-assisted dev, LLM interfaces); experience with platform unification or large-scale architectural transitions; consumer electronics or robotics background.
