What you will do: As a Technical Lead on the Defense team, you'll lead a small team of engineers while staying hands-on, guiding implementation from design through delivery. Your work will span building innovative products from scratch (0 to 1) and evolving existing systems as they scale (1 to n). You'll operate in a fast-paced environment where you'll help set the standard for technical excellence, working alongside a cross-functional team of platform engineers, domain experts, deployment strategists, and end users. You'll solve real problems that make a difference — putting better decision-making platforms in operators' hands and improving the safety of our airspace. What we value: - 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. - Proficient in leveraging modern LLM tools to accelerate development workflows and enhance code quality. - Ability to partner across teams and directly with customers, turning ambiguous requirements into shipped software. - Comfort operating independently in a fast-paced and dynamic environment - driving work to completion without waiting for direction. - Curiosity and a desire to grow, including learning our customers' domain deeply enough to anticipate their needs. - Ability to travel. - Ability to obtain security clearance. 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.
