- 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).

- 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.

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.
