Job summary

Tiberius Aerospace is seeking a Senior GNC Software Engineer to own the translation of GNC algorithms into production-grade real-time embedded flight software. You will implement navigation filters, guidance laws, and autopilot control in C/C++ for the flight computer, and you will own the SIL/HIL infrastructure for end-to-end verification.

The role requires leadership in algorithm translation, numerical stability, and fixed/floating-point performance, with ownership of the development and test

Qualifications

• 8+ 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.
• Experience implementing Kalman filter variants or flight control laws in embedded production code.

Responsibilities

• Implement GNC algorithms including the navigation filter, guidance law, and autopilot control laws in embedded C or C++ targeting the flight computer.
• Define and own the GNC flight software architecture including task scheduling, sensor data interfaces, GNC state machine, and fault detection logic.
• Develop and maintain the Software-in-the-Loop environment integrating GNC flight code with the 6-DOF trajectory simulation for closed-loop algorithm verification.
• Design and build the Hardware-in-the-Loop test bench including GPS signal stimulation, IMU stimulation hardware, actuator emulation, and avionics bus interfaces.
• Apply and enforce flight software coding standards and institute code review processes across the GNC software team.
