Navigation Hardware Engineer | AR5

Location: 100% on-site in Caldas da Rainha Experience: 4+ Years You will be responsible for ensuring that the "nervous system" of the AR5 — from IMUs and GNSS/RTK to LiDAR and Optical Flow — delivers high-fidelity data to the autopilot, free from noise, vibration, or electromagnetic interference.

What You'll Do

(Product Focus) Sensor Research & Selection: Lead the benchmarking of state-of-the-art sensors, balancing extreme performance with SWaP (Size, Weight, and Power) constraints. Hardware Design & Physical Integration: Design electronic and mechanical integration solutions, with a strong focus on signal integrity, vibration isolation, and EMI/EMC shielding.

Embedded Development: Develop drivers and firmware (C/C++) to interface sensors via aeronautical protocols (DroneCAN, SPI, I2C, UART), ensuring precise time synchronization of data. Calibration and Validation: Execute complex calibration routines (thermal compensation of IMUs, magnetometer calibration) and analyze flight logs to diagnose anomalous behavior.

Navigation Architecture: Collaborate with the Flight Control Software team to align hardware capabilities with the requirements of state estimation algorithms.

What We're Looking For

4+ years in navigation hardware integration or control systems.

Education

Electrical Engineering, Industrial Automation, or related fields. Low-Level Expertise: Proficiency in C/C++ for embedded systems and a deep understanding of industrial/aeronautical communication protocols. Hands-on Lab Skills: Experience with oscilloscopes, logic analyzers, and PCB prototyping tools. Data Analysis: Ability to interpret complex telemetry to identify sensor noise, bias, or instability.

Differentiating Factors (Nice to Have) Experience with Ardu. Pilot or PX4 (driver/HAL level). Knowledge of signal processing and Kalman filters. Experience with aeronautical hardware certification standards.

What We Offer

An excellent working environment and the opportunity to make a real difference; A salary commensurate with proven experience; Daily transportation from Lisbon, Leiria, Alcobaça and Rio Maior; If you're ready to embrace this opportunity, send us your application.
