Navigation Hardware Engineer | AR5
Confirmed on the employer's own hiring board on Oct 17, 2026. First seen by Alion on Mar 18, 2026. Tekever scores A on the Alion truth index.
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
Experience: 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 ArduPilot 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.
