Software Engineer (Civil Aviation)

What You Will Do

As a Software Engineer for the Civil Aviation team, you will design and build a backend system that will operate at the center of U.S. air travel for the next decade and beyond. This is a platform that needs to be right the first time and maintainable by future engineers who had no hand in building it.

The core technical challenge is data fusion at operational scale: ingesting disparate, noisy, and potentially conflicting data streams, from radar, flight plans, weather systems, operator inputs, and more, and resolving them into a single, authoritative view of the world. From there, the system projects that state forward in time, enabling optimization across a complex set of competing conditions and constraints.

The person in this role needs to have strong intuitions about how to model uncertainty, how to reason about data provenance and confidence, and how to build systems that degrade gracefully when inputs are incomplete or wrong.

What We Value

• Experience building production-grade backend or distributed systems where strong design principles make the difference in maintainability, scalability, and performance.
• Proficiency in at least one modern programming language. We work in Rust and Python and expect you to have the foundation to quickly learn these languages.
• Experience with data integration, data storage, data processing, and data modeling systems.
• Experience with AWS and cloud-native architectures.
• Exposure to high-availability systems (e.g., “four nines” reliability) is a strong plus.
• Ability to work in complex, multi-system environments with evolving data models.
• Strong collaboration skills and comfort working across teams in a mission-critical environment.
• Proficient in leveraging modern LLM tools to accelerate development workflows and enhance code quality.
• Domain experience in aviation, mapping, geospatial systems, or any field where the physical world is the source of truth and data is always an approximation of it is a strong plus.

How We Hire

We look at the interview process not as a screening or test, but rather as an opportunity to simulate what it would look like working together. We build the interview process around you.

ASI works with export-controlled technology and restricted U.S. Government data, including on contracts mandating U.S. immigration status and location restrictions for performing personnel. Employment offers are contingent on ability to timely obtain all required authorizations for contemplated job duties.
