About Size Stream 

Size Stream is a technology company specializing in advanced 3D body scanning for apparel and health & fitness applications, including a widely used in-store scanning solution. The team is multi-disciplinary and innovative, applying state-of-the-art and increasingly AI-forward approaches to industry-leading body measurement software. 

Role Overview 

The Mobile Application Team Lead is a hands-on “player/coach” responsible for leading the team that builds and maintains Size Stream’s globally deployed iOS and Android applications. The role blends 50–60% hands-on coding with leadership, architecture, and process ownership, while staying aware of evolving legal, privacy, and technical requirements for industry-scale mobile applications. The Team Lead collaborates closely with other engineering teams and business stakeholders to deliver secure, robust, and compliant mobile experiences. 

Key Responsibilities 

• Lead, mentor, and manage a team of iOS and Android developers (employees and contractors) delivering new features and improvements. 

• Design and implement robust, efficient, and maintainable app features in Swift, Objective-C, and Kotlin/Java. 

• Manage setup, configuration, and operation of third-party mobile integrations such as RevenueCat, AppsFlyer, Firebase, and similar services. 

• Oversee and continuously improve the mobile build and release pipeline for Apple App Store and Google Play. 

• Maintain and evolve Size Stream’s mobile scanning SDK offering, including documentation, versioning, and lifecycle management. 

• Provide technical support for client developers integrating with Size Stream SDKs and APIs. 

• Support integration with back-end APIs in close collaboration with cloud platform and eStore teams. 

• Provide QA with requirements and context for test cases; review and assess the quality of QA testing and test coverage. 

• Assist operations with troubleshooting production issues, diagnosing mobile-related incidents, and supporting customer-facing teams. 

• Contribute to and help evolve Agile processes, CI/CD practices, and automation, with an eye toward AI-forward tooling where appropriate. 

• Communicate complex technical topics clearly to non-technical stakeholders, including business unit leaders and product managers. 

• Primarily remote with an expectation of being able to work onsite in Cary, NC for key meetings or collaboration events as needed (for example, a few times per quarter rather than strictly 2 days per week). 

Required Qualifications 

• US Citizenship is mandatory. 

• Bachelor’s degree in Computer Science, Engineering, Applied Math, Imaging Science, Physics, or a related discipline, or equivalent practical experience. 

• Demonstrated experience developing, shipping, and supporting production iOS and Android apps, including code review and store deployment. 

• Strong coding skills in Swift and Objective-C, with hands-on experience in Android development (Kotlin or Java). 

• Experience working with and extending existing/legacy mobile codebases; strong familiarity with git and branching workflows. 

• Proven ability to collaborate with QA on debugging, feature validation, and requirements traceability. 

• Excellent written and verbal communication skills, including the ability to explain technical concepts to non-technical audiences. 

• Strong sense of ownership, self-direction, and comfort working with distributed/remote teams in a fast-evolving environment. 

Nice-to-Have Skills 

• Experience with React Native, browser-based scanning, or other hybrid/mobile web frameworks. 

• Knowledge of computer vision and on-device ML (e.g., CoreML) or AI-forward features in mobile applications. 

• AWS platform development experience, including Python, Lambda, DynamoDB, and related services. 

• Familiarity with automated mobile build and testing frameworks (e.g., Fastlane, Gradle pipelines, XCTest / UI testing, or similar tooling). 

• Experience with Agile methodologies, startup or product launch environments, and cross-platform development across Windows and Unix-based systems. 

• Experience using AI-assisted development tools (for example, code generation, automated refactoring, or intelligent test creation) as part of the software delivery workflow. 

Benefits & Perks 

• Three weeks paid vacation annually plus 13 company-paid holidays. 

• Comprehensive healthcare plan and education benefits. 

• Opportunity to work on a globally deployed, industry-leading mobile product with a team focused on innovation and practical AI-forward enhancements.
