Senior Radar Algorithm Engineer

About the role

As a Senior Radar Algorithm Engineer at Castelion, you will develop and deploy advanced algorithms for air‑to‑air radar systems operating in contested, modern electronic‑warfare environments. You will own the full lifecycle from algorithm design through production‑ready implementation, validation, and integration into real hardware systems, directly shaping critical capabilities.

Responsibilities

• Own end‑to‑end development of air‑to‑air radar algorithms—from concept through production—ensuring performance, affordability, testability, and scalability.
• Design, implement, and validate radar mode logic in Python or Rust, delivering robust performance in modern electronic‑warfare environments.
• Develop and execute verification and validation plans across simulation, chamber testing, captive flight, and live‑fire scenarios, including calibration considerations.
• Operate within a disciplined software‑engineering environment, leveraging version control, code reviews, CI/CD, and testing frameworks.

Basic Qualifications

• Bachelor's or Master's degree in Electrical Engineering, Computer Science, Physics, or a related technical field.
• Direct experience with air‑to‑air radar systems and associated algorithms.
• Strong background in signal processing, detection, tracking, and radar modes.
• Proficiency in Python and/or Rust, with experience writing production‑quality code.
• Ability to operate in a disciplined software‑engineering environment (e.g., Git, code reviews, testing, issue‑tracking tools like Jira).

Preferred Skills and Experience

• Experience working in electronic warfare or contested RF environments.
• Background in taking algorithms from concept through deployment on hardware systems.
• Familiarity with radar system calibration, integration, and testing across multiple environments.
• Experience building scalable, maintainable software architectures for real‑time systems.

Additional Requirements

• Ability to work extended hours, including evenings and weekends, when required to meet aggressive timelines.
• Full‑time onsite presence in Allen, TX.
• U.S. citizenship required; ability to obtain and maintain a U.S. government‑issued security clearance (currently not required but may be in the near future).

Benefits and Perks

• Meaningful long‑term equity for all full‑time employees.
• Four weeks of paid time off plus ten company‑paid holidays.
• Comprehensive health benefits with 100% employee‑covered medical costs and strong dependent coverage, plus dental and vision plans.
• Paid parental leave.
• $100 monthly fitness stipend.
• Onsite EV charging.
• Catered meals, company‑covered food during high‑demand periods, and a fully stocked kitchen.
