GNC Embedded Engineer

Interface with the flight computer hardware team on processor selection, memory architecture, sensor bus protocols, and boot sequence requirements.

Coordinate GNC software schedule and deliverables with systems engineering, the navigation team, and the I&T team.

Support range test activities by providing GNC software configuration control, pre-test checkout procedures, and post-test log data extraction.

Participate in configuration control board reviews for GNC software changes and maintain the software version log.

Support environmental qualification by preparing GNC software test configurations for vibration, thermal, and shock testing.

Provide GNC software technical inputs to subcontractor statements of work for GPS receiver and IMU firmware interfaces.

B.S. or M.S. in Computer Engineering, Electrical Engineering, or Aerospace Engineering.

8 or more years of embedded flight software development for flight-critical defense or aerospace systems.

Expert-level C and C++ in real-time embedded environments including RTOS and bare-metal architectures.

Demonstrated experience implementing Kalman filter variants or flight control laws in embedded production code.

Proficiency in MATLAB and Simulink Model-Based Design including production C code generation using Embedded Coder or equivalent.

developing or operating SIL and HIL test infrastructure for GNC algorithm verification.

Must be a U.S. citizen and eligible to obtain and maintain a U.S. government security clearance.

Experience with GPS receiver software interfaces including NMEA, binary proprietary protocols, and M-code or SAASM pulse-per-second and timing interfaces.

Background implementing DO-178C, MISRA-C, or equivalent safety-critical software standards in a flight program.

with high-g inertial sensor digital interfaces including SPI or UART IMU protocols and in-flight calibration algorithms.

Familiarity with MIL-STD-1553, RS-422, or ARINC 429 avionics bus interfaces.

Background with high-g avionics design considerations such as connector retention, PCB via-fill, and component derating under high-g launch load.

with FPGA co-design for navigation algorithm pre-processing or sensor timing synchronization.

Active U.S.

Secret or Top Secret security clearance.

An embedded GNC software engineer who can implement a navigation filter from a MATLAB prototype, make it run deterministically on a flight computer, and verify it against a 6-DOF plant model.

Someone who owns the SIL and HIL infrastructure, not just uses it, and can build it from scratch when it does not yet exist.

An engineer with the numerical instincts to know when a 32-bit float is not enough and the discipline to enforce coding standards that matter.

A technical leader comfortable reviewing algorithm equations with navigation engineers and debugging SPI bus timing issues with hardware engineers on the same day.

A high-ownership engineer who treats flight software as a safety-critical deliverable and builds accordingly.

Tiberius Aerospace offers competitive base compensation commensurate with experience, equity participation, comprehensive health benefits, and 401(k).

Specific compensation will be discussed during the interview process.

This role offers the opportunity to build the GNC flight software function at Tiberius Aerospace from the ground up on a program where the algorithm complexity and flight environment are genuinely challenging.

The Senior GNC Software Engineer will own the implementation stack, build the test infrastructure, and close the software V&V against a real flight computer.

As Tiberius grows, this person will be positioned to lead the broader flight software team and influence avionics architecture decisions on follow-on programs.
