UAV Design & Aerodynamics Engineer

ARQUIMEA we are a technology company operating globally and providing innovate solutions and products in highly demanding sectors.

Our areas of activity are Aerospace Defense & Security Big Science Biotechnology and Fintech.

In ARQUIMEA AEROSPACE DEFENCE & SECURITY develops safer and more reliable defense systems through technology including unmanned aerial systems (UAVs) sensing systems command and control software and aiming systems.

The UAV Design & Aerodynamics Engineer will contribute to the conceptual and preliminary design of unmanned aerial vehicle platforms translating mission and system requirements into viable aircraft configurations. The role combines aerodynamic design aircraft performance 3D design and system-level integration with a strong focus on making practical design trade-offs across the complete UAV.

The engineer will own and support aerodynamic sizing flight-performance prediction configuration definition and propulsion-related trade studies while understanding how the airframe must accommodate and support the rest of the vehicle: propulsion servos and control surfaces avionics autopilot antennas payloads energy storage cooling and other onboard systems.

Key Accountabilities:

Perform conceptual and preliminary design of fixed-wing multirotor VTOL and other UAV configurations balancing mission needs aerodynamic efficiency mass volume manufacturability and system constraints.

Develop and evolve 3D aircraft configurations and packaging using CAD tools working from early layouts through prototype-ready geometry.

Perform aerodynamic sizing and engineering calculations for wings tails control surfaces and complete-aircraft configurations using analytical and low-order methods.

Build and maintain performance models covering cruise endurance range climb glide stall manoeuvre capability and other mission-relevant flight conditions.

Perform preliminary stability and control assessments including static margin trim control-surface sizing and centre-of-gravity envelope considerations providing inputs to GNC and flight-control teams.

Contribute to propulsion and energy-system sizing and trade studies including motor/engine propeller battery or fuel selection power requirements and propulsive efficiency.

Drive system-level airframe integration decisions ensuring adequate space interfaces installation constraints and aerodynamic compatibility for servos avionics autopilot GNSS/INS antennas payloads batteries/fuel and other onboard systems.

Perform multidisciplinary trade studies and support configuration decisions involving performance mass centre of gravity packaging propulsion and operational constraints.

Use appropriate engineering tools for preliminary aerodynamic analysis sizing and performance modelling such as XFLR5 AVL VSPAero or equivalent.

Define analysis needs and work with CFD and structural specialists when higher-fidelity simulations or detailed calculations are required integrating their results back into the aircraft design.

Support prototype build ground testing and flight testing; analyse flight-test data and correlate actual aircraft performance with engineering predictions.

Prepare design justifications trade-study reports performance documentation configuration definitions and technical inputs for design reviews.

Level Degree:

Bachelors or Masters degree in Aeronautical Engineering Aerospace Engineering or a closely related engineering discipline.

Additional Training/Qualifications:

Strong fundamentals in aerodynamics flight mechanics aircraft performance and preliminary aircraft design.

Practical experience with 3D CAD tools and the ability to develop complete aircraft configurations rather than only analysis models.

Ability to perform engineering-level aerodynamic and performance calculations independently and to turn results into design decisions.

Experience with preliminary aerodynamic tools such as XFLR5 AVL VSPAero or equivalent.

Knowledge of Matlab Python Excel or equivalent tools for calculations performance models data reduction or engineering automation is valued.

Good understanding of propulsion and energy-system sizing for UAVs including propellers electric motors combustion engines batteries and fuel systems as applicable.

Strong system-level mindset: able to understand how aerodynamic and mechanical design supports avionics flight controls sensors communications payloads and other UAV subsystems.

Ability to work hands-on with prototypes and to support manufacturing integration and flight-test activities.

Specific Knowledge:

UAV configuration design aerodynamic sizing stability and control aircraft performance and propulsion integration.

Understanding of mass properties centre-of-gravity management and packaging constraints in compact UAV platforms.

Familiarity with fixed-wing multirotor and/or VTOL UAV architectures and their practical integration constraints.

Knowledge of UAV piloting simulator operation or flight-test activities is valued.

Minimum Required Experience:

05 years of experience in UAV or aircraft design preliminary aerodynamics performance engineering or a comparable multidisciplinary aerospace development role. Experience participating in the development of a complete UAV or aircraft product from early design through prototype and flight testing is highly desirable.

The position is located in our Headquarters of Torrejón de Ardoz (Madrid).
