Principal Mobile Engineer
About The Position
We are looking for a hands-on Principal Mobile Engineer to own and modernize our iOS and Android application ecosystem — spanning modern React Native apps and legacy native codebases. You will define and drive the North America mobile roadmap while collaborating globally, directly shaping connected products in access control, security, gate and door automation, and IoT-enabled solutions. This is a high-ownership builder role in a lean, empowered team. You will combine strategic leadership with daily hands-on coding, architecture decisions, and modernization work. The ideal candidate thrives on turning complex legacy systems into clean, reliable, high-impact mobile experiences that connect users to real-world hardware. This is not a people-management or pure design role — you will stay close to the code and own meaningful outcomes.
Requirements
- 8+ years of experience building and shipping production mobile applications on iOS and Android, preferably in connected devices, IoT, or customer-facing environments
- Experience working in mixed React Native + native + legacy environments, with a proven ability to assess applications and systematically reduce technical debt
- Experience with mobile CI/CD pipelines, crash reporting (Sentry or similar), monitoring, and app store delivery processes
- Comfortable working in Atlassian Cloud (Jira, Confluence, Bitbucket) and collaborating effectively across global teams and regions
- Experience with connected devices, IoT workflows, hardware integration, or physical security/access-control products
- Practical experience with key connected-product flows: device onboarding, pairing, remote control, notifications, and user access models
- Ability to use Figma for lightweight prototyping and collaboration with design/product teams
- AWS experience, particularly with API Gateway, Cognito, Lambda, IoT Core, S3, and CloudWatch
- Familiarity with modern AI-assisted development tools (e.g., ChatGPT, Claude, Cursor) and the judgment to use them effectively while maintaining a secure and well-tested codebase
- Excellent JavaScript and TypeScript knowledge, with strong expertise in React Native and React, including shared web + mobile codebase architectures
- Solid working knowledge of Swift and Kotlin, plus ability to work with Objective-C and Java in legacy codebases
- Deep understanding of mobile architecture (state management, performance, API integration, authentication, and app lifecycle)
- Familiarity with secure-by-design principles, identity management, privacy, and handling sensitive user data
- Strong written communication and verbal skills
- Proven ability to multi-task, set project priorities, establish department/discipline goals and objectives for self
- Computer literacy required; including advanced skills in Microsoft applications (i.e. Excel, Word, PPT, etc.)
- Strong attention to detail
- Positive attitude, self-motivated and eager to succeed
Responsibilities
- Own the strategy, architecture, and hands-on modernization of our mobile ecosystem across React Native and legacy iOS/Android applications
- Define and execute the North America mobile roadmap while representing regional needs in global planning and execution
- Assess the current application landscape and make pragmatic decisions on what to maintain, modernize, rebuild, consolidate, or retire
- Deliver high-quality code through feature development, performance optimization, troubleshooting, and technical debt reduction
- Elevate engineering standards across release processes, observability, crash reporting, monitoring, and platform compliance
- Proactively track and adapt to evolving iOS and Android platform changes, deprecations, OS releases, and app store requirements
- Partner closely with cloud, platform, product, and design teams to create seamless connected-device experiences (pairing, remote control, notifications, authentication, onboarding, etc.)
- Build strong cross-functional and cross-regional relationships to drive aligned execution
- Implements and maintains department policies and standards
- Required to have a strong comfort-level communicating throughout all levels of the organization
- Understand, support and execute all work according to the established procedures of the organization
