Mobile / Cross-Platform Lead Developer or Solutions Architect — United States

About the Role

The Lead Developer / Solutions Architect recommends the technical approach and leads the build of a cross-platform app for iOS, Android, and the web. You own the architecture, integrations, admin tools, SMS and push notifications, and the path to production and app store release.

Responsibilities

• Build guided navigation, search and filtering with location data, forms and referrals, scheduling, event registration with calendar integration, and optional user accounts with document or resume upload.

• Set up hosting, APIs, environments, CI/CD, backup, monitoring, and disaster recovery.

• Implement security controls; data minimization, role-based access, encryption, audit logs, retention and deletion.

• Build to WCAG 2.1 AA, with screen-reader support, scalable text, and multilingual support.

• Manage App Store and Google Play submission under agency-owned developer accounts; write technical documentation.

Qualifications

• 6+ years in software development, with 4+ years building mobile apps and at least two cross-platform apps live in the App Store and Google Play.
