Aerospace Systems Integration Engineer

Location: San Francisco (Onsite)
Type: Full-time
Start Date: ASAP

• Design and implement hardware integration solutions for aerospace and defense platforms
• Build real-time systems for avionics, satellite, and unmanned vehicle applications
• Develop software interfaces for flight systems, sensors, and mission-critical hardware
• Integrate and test embedded systems across multiple aerospace protocols and standards
• Work on hardware-in-the-loop simulation and validation environments
• Collaborate with aerospace customers on system architecture and integration requirements
• Ensure compliance with DO-178C, DO-254, and other aerospace certification standards

Strong experience with:

• Aerospace systems integration and avionics architectures
• Real-time embedded systems (RTOS, bare-metal, Linux RT)
• Aerospace communication protocols (MIL-STD-1553, ARINC 429, SpaceWire, CAN)
• Hardware-software co-design for flight systems
• Systems programming in C/C++ and embedded development
• Integration testing and hardware-in-the-loop simulation

Familiarity with:

• Satellite systems, payload integration, or space-grade hardware
• DO-178C/DO-254 certification processes
• FPGA development and hardware acceleration
• GNC (Guidance, Navigation, Control) systems
• Defense programs and classified development environments

We're looking for an aerospace systems engineer who can bridge the gap between flight hardware and intelligent software — someone who has shipped systems that fly.

You should have:

• Deep experience integrating complex aerospace hardware and software systems
• Understanding of the unique constraints of flight-critical systems
• Track record of successful system integration on aerospace programs
• Ability to work across mechanical, electrical, and software domains
• Excitement about bringing AI-native tooling to aerospace and defense

Requirements:

• Master's or PhD in Aerospace Engineering, Electrical Engineering, Computer Engineering, or equivalent experience
• 5+ years of aerospace systems integration experience
• Experience with defense or space programs preferred
• Active security clearance or ability to obtain one preferred
• Willingness to work startup hours, in-person (weekends included) at our San Francisco office
• Work authorization in the United States

We're building the intelligence layer for hardware — real-time systems that control physical machines with zero tolerance for latency or failure.

What we offer:

• Startup-level equity and highly competitive salary
• Ownership over aerospace integration that defines how flight systems are built
• Problems at the intersection of AI, embedded systems, and aerospace
• Close collaboration with aerospace and defense customers building the future
