Software Engineer, iOS/Mobile - Electronic Flight Bag (EFB)

About Beacon AI

We’re a fast-moving team of aviators, engineers, and operators building an AI platform to make flying safer, more efficient, and more capable. Backed by top investors, we’ve secured a dozen Department of Defense contracts and partnered with major airlines to deliver mission-critical systems. We operate without silos or heavy processes. Small, focused teams own what they build, ship quickly, and learn fast, pushing the boundaries of how humans and AI work together in aviation.

Role Overview

We are seeking an iOS Software Engineer to join our mobile team and help build high-impact iOS applications primarily targeting iPad that support our flight safety platform. In this role, you will work closely with senior engineers and designers to develop user-facing features and contribute to production systems. You will have experience building Electronic Flight Bag (EFB) applications, working with location services and map navigation, and integrating with external hardware and edge devices. You are performance obsessed where your applications handle large datasets efficiently such as millions of data points for wind and weather data, and render aviation instruments with precision and zero lag. You understand that EFB applications must remain fully operational in offline and degraded connectivity environments, and you know how to build for that reality. You'll grow your iOS expertise while working on real-time, safety critical applications where reliability and accuracy are non negotiable.

What You'll Do

• Design and implement iOS features using Swift, SwiftUI, UIKit, and modern iOS frameworks.

• Build and maintain high performance mobile applications that handle large datasets such as wind and weather data in real time.

• Develop and integrate Electronic Flight Bag (EFB) features including location services, map navigation, and aviation instrument displays.

• Integrate with external hardware and edge devices to support real time data ingestion and application functionality.

• Architect offline-first experiences and graceful degradation strategies to ensure full application functionality in low or no connectivity environments.

• Implement background processing and long-running compute tasks using Swift Concurrency, async/await, and background task APIs to support continuous data handling without impacting the user experience.

• Apply data security best practices including Keychain storage, encryption, and secure data handling to protect sensitive flight and user data.

• Collaborate with senior engineers and designers to deliver precise, reliable, and intuitive mobile experiences.

• Participate in code reviews and follow established iOS best practices and architectural patterns.

• Help ensure code quality, performance, and maintainability through testing and documentation.

What Will Make You Successful

• 3+ years of experience developing iOS applications, or equivalent experience through internships, projects, or coursework.

• Experience with Swift and SwiftUI, with some exposure to UIKit and common iOS frameworks.

• Familiarity with building or working on EFB applications, location services, or map navigation frameworks such as Mapbox or MapKit.

• Experience integrating with external hardware or edge devices and managing real time data pipelines.

• Demonstrated ability to optimize application performance and handle large datasets without degradation in speed or reliability.

• Experience building offline-first or connectivity-resilient mobile applications, including local data caching and sync strategies.

• Familiarity with background processing patterns and long-running task management using Swift Concurrency or background task frameworks.

• Understanding of iOS data security practices including Keychain, encrypted storage, and secure coding principles.

• Familiarity with asynchronous programming concepts such as async/await, multithreading, or GCD.

• Strong problem solving skills and eagerness to learn from feedback and mentorship.

• Ability to work effectively in a collaborative, fast moving environment.

Bonus Points

• Experience building or optimizing applications specifically for iPad, including split view, multitasking, or large screen layout design.

• Passion for aviation and a desire to improve air travel efficiency and safety.

• Experience working on safety critical or mission critical systems.

• Familiarity with CI/CD workflows or cloud backed mobile systems.

• Interest in real time data, sensors, or hardware adjacent systems.

Work Location
This is a hybrid role based in San Carlos, CA, with 3+ days per week onsite and the option to work remotely on remaining days.
