Job description

Job Overview

As a Flight Software Engineer, you will design and develop mission-critical software that enables the operation of advanced aerospace and defense systems. You will work closely with cross-functional engineering teams to translate system requirements into reliable, real-time embedded software, integrating with avionics hardware, sensors, and communication subsystems. This role involves contributing across the full software development lifecycle, including design, implementation, testing, and validation in simulation and hardware-in-the-loop environments. The ideal candidate is passionate about building high-reliability software that meets the rigorous safety, performance, and security standards required for defense missions.

What You’ll Work On

• Real-time flight software architecture for autonomous systems
• Guidance, navigation, and control software integration with onboard sensors
• Interfaces with IMUs, GPS, seekers, and motor/actuation systems
• High-reliability communication between processors (CAN, UART, Ethernet, etc.)
• Hardware-in-the-loop (HITL) and software-in-the-loop (SITL) testing infrastructure
• Telemetry, logging, and system health monitoring
• Flight test support and debugging
• Our systems run across heterogeneous compute environments ranging from embedded microcontrollers to Linux flight computers, and must perform reliably under strict timing and resource constraints.

Qualifications

• Strong C or C++ in performance-critical systems
• Degree in Computer Science, Computer Engineer, or Computer Engineering
• 7+ years of experience working as a Flight Software Engineer
• Real-time or near-real-time software experience
• Experience with Guidance / navigation / control systems team
• Linux-based embedded platforms
• Hardware bring-up and debugging
• Comfortable working close to hardware, reading datasheets, debugging buses, and instrumenting systems in flight tests.

ITAR Requirements

• To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) refugee under 8 U.S.C.1157, or (iv) asylee under 8 U.S.C.1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
