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

• 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.

Requirements

• Formação: Engenharia Eletrotécnica, Automação Industrial ou áreas similares.
• Domínio de Baixo Nível: Proficiência em C/C++ para sistemas embebidos e compreensão profunda de protocolos de comunicação industrial/aeronáutica.
• Hands-on Lab: Experiência com osciloscópios, analisadores lógicos e ferramentas de prototipagem de PCB.
• Análise de Dados: Capacidade de interpretar telemetria complexa para identificar ruído, bias ou instabilidade de sensores.
• Experiência com ArduPilot ou PX4 (nível de driver/HAL).
• Conhecimentos de processamento de sinal e filtros de Kalman.
• Experiência com normas de certificação de hardware aeronáutico.

Benefits

• Oferecemos um excelente ambiente de trabalho e uma oportunidade de fazeres a diferença.
• Salário compatível com o nível de experiência comprovada.
• Transporte diário de Lisboa e Leiria.
