• Partner with backend engineers, product managers, and UX/UI designers to make informed design and implementation decisions.
• Ensure reliable, maintainable frontend systems through automated testing, clear documentation, and strong engineering standards.
• Build reusable components and internal libraries to accelerate future development.

What Will Make You Successful

• 9+ years of experience building and shipping high-performance, user-facing web applications.
• Deep expertise in React, TypeScript, JavaScript, state management, and modern web standards (HTML/CSS).
• Strong experience with asynchronous frontend patterns and efficient handling of live and historical data streams.
• Proven ownership of complex features or product areas, driving work from concept through delivery with a high degree of autonomy.
• Proactive, resourceful mindset with the ability to operate effectively in fast-moving, ambiguous environments.
• Consistently sets and upholds a high technical bar through design decisions, code quality, mentorship, and hiring input.
• Ability to analyze and optimize frontend performance for scalability, responsiveness, and reliability.

Bonus Points

• Passion for aviation and a desire to improve air travel efficiency and safety.
• Experience with geospatial or mapping tools such as Mapbox or Cesium.
• Deep experience with live data streaming and playback systems.
