Backend Software Engineer, Weather & Aviation

The Role:

 

Spire's Weather & Aviation business delivers global weather forecasts, flight tracking, and aviation data to customers who rely on it every day to make operational decisions. As we grow, we're investing in the engineering foundations that keep our platform fast, secure, and dependable at scale.

 

We're seeking a Senior Backend Software Engineer who has helped production systems scale, harden, and stay reliable as usage and expectations grew.

• Build and improve AWS-based backend services with a focus on availability, fault tolerance, and performance as load grows
• Design and implement authentication and authorization features using OIDC and OAuth 2.0, including token handling, service-to-service auth, and access control
• Develop and maint
