Job Description

We are looking for a technical visionary who balances high-level strategy with hands-on execution. You will set the gold standard for UI development, ensuring our applications are as inclusive as they are performant. Based in our Baltimore office, you will play a pivotal role in mentoring our software team, advocating for the end-user, and bridging the gap between ux design and technical feasibility.

  • Taking an AI first approach to development and debugging, using tools such as Claude, Cursor, Codex.
  • Deep technical expertise in Flutter for both mobile and web applications, with a proven track record of shipping high-quality products.
  • Advanced proficiency in predictable app state management patterns such as BLoC, Riverpod, or Redux, with the ability to justify architectural choices based on project scale.
  • Deep understanding of the Flutter rendering pipeline (Widget > Element > RenderObject) and experience using DevTools to diagnose jank, memory leaks, and overdraw.
  • Proven experience writing custom Method Channels to interface with native iOS (Swift) and Android (Kotlin) APIs when Flutter plugins fall short.
  • Experience architecting multi-package monorepos or federated plugins to promote code reuse across web and mobile targets.
  • Advanced knowledge of web accessibility standards (WCAG) and a commitment to building inclusive digital experiences.
  • Direct experience managing the submission, release, and maintenance processes for both iOS and Android platforms.
  • Experience implementing frontend monitoring tools and leveraging browser-level data to diagnose issues and optimize performance.
  • Demonstrated ability to lead complex projects and elevate the technical skills of those around you through mentorship and clear communication.

Desired Skills:

  • Familiarity with native iOS (Swift) or Android (Kotlin) development to further optimize cross-platform bridges.
  • A keen eye for design, user experience,  and a passion for micro-interactions that delight users.
  • Experience migrating legacy systems or scaling frontend architectures in a growing, medium-sized company environment.

Education & Experience:

  • Bachelor’s Degree in Computer Science, Computer Engineering, or related field. Equivalent experience may substitute for education.

What We Do

Alertus - Redefining Mass Notification for 20+ Years Our Mission is to enable organizations to disseminate information to help protect lives, secure assets, and maintain business continuity. OUR MISSION IS PERSONAL. We are committed to providing customizable, scalable, and cost-effective mass notification solutions because we know even a few seconds of warning can help save lives during an emergency. In 2001, an F3 tornado ripped through the University of Maryland campus. There was no warning, and two students — sisters — were killed. The tornado caused dozens of injuries and millions of dollars in damages. An idea was born to engineer a mass notification solution that can be implemented anywhere and activated quickly to help prevent another tragedy. Alertus was founded in 2002 and has focused its efforts on developing superior lifesaving notification solutions ever since. Alertus' dedicated teams of safety, security, and technology leaders are committed to continuously raising the bar for mass notification. Our technology is state of the art, with interoperable software solutions that help tie legacy systems into our next-generation audible and visual notification hardware. It's not enough for us for our customers to have our products. As their trusted partner in mass notification, we want to ensure customers are at peak readiness with the training and support they need to get critical notifications out at a push of a button. We offer pre-sales professional services, ongoing customer training, and 24/7 customer support.
