Mechanical Design Engineer (MJF Senor & RF Structures - EVO)

Join DeltaQuad as a Mechanical Design / Creative Engineer

At DeltaQuad, you’ll work on technology that truly matters. As a pioneer in long-range electric VTOL drones (Vertical Take-Off and Landing), we develop robust systems in collaboration with trusted partners, which are deployed across the globe for defence, agriculture and inspection. Our drones are reliable, user-friendly, and built to perform in demanding environments.

We combine technical innovation with a pragmatic mindset. What we do today shapes where we’ll be tomorrow and you’ll play a crucial role in that journey.

Our core values:

• Partnerships – Growing together through long-term collaboration
• Customer focus – Thinking and acting with the customer in mind
• Ownership – Taking responsibility for what we do
• Innovation – Finding smart, practical solutions
• Excellence – Focused on quality and results
• Team spirit – Building trust, growth, and enjoyment together

As a Mechanical Design / Creative Engineer, you will design, prototype, and bring to life advanced mechanical and structural solutions for UAV systems. Your focus lies on sensor integration, RF payloads, and lightweight, high-performance components.

You operate at the intersection of creativity and execution, turning field feedback, failure data, and real-world insights into rapid design improvements. Your work directly impacts UAV reliability, resilience, and performance in demanding environments.

Key responsibilities

Design & Prototyping

• Design and optimise mechanical components, sensor mounts, RF structures, and payload integrations
• Develop complex 3D CAD models and assemblies in SolidWorks (surfacing, configurations)
• Leverage additive manufacturing (MJF, SLS, FDM, SLA) for rapid prototyping and low-volume production
• Work with advanced materials such as PA12, carbon composites, and high-temperature polymers
• Design for manufacturability: tolerances, wall thickness, support strategies, post-processing
• Create modular, serviceable designs for fast field repair and replacement

System Adaptation & Validation

• Translate real-world feedback into fast design iterations
• Perform structural analysis (hand calculations + basic FEA)
• Validate designs against stress, vibration, thermal, and environmental conditions
• Ensure aerodynamic efficiency of external components (fairings, radomes, pods)
• Design with sealing, crash tolerance, and EMC considerations in mind

Integration & UAV Performance

• Develop low-drag housings and payload structures for UAV platforms
• Understand how design choices affect flight stability, endurance, and performance
• Ensure compatibility across systems, payloads, and configurations

Collaboration & Continuous Improvement

• Work closely with Integration, Flight Test, and Software Engineers
• Participate in hands-on assembly, testing, and validation (lab & field)
• Explore new materials, manufacturing techniques, and design approaches
• Maintain strong documentation and configuration control using PDM

• Solid understanding of advanced materials (PA12, carbon fibre composites, reinforced polymers)
• Experience with structural analysis, vibration design, and basic FEA
• Knowledge of aerodynamics in small UAV systems
• Familiarity with FMEA, CFD, and EMC-aware design is a plus

Your mindset

• Hands-on engineer who enjoys being in the lab (or hangar)
• Thrives under pressure and embraces rapid iteration
• Balances speed with precision and structural integrity
• Creative, pragmatic, and solution-driven
• Strong discipline in documentation and version control

What we offer

• Coaching and professional growth opportunities
• 27 vacation days (based on full-time)
• 38-hour workweek with flexible working hours
• Travel reimbursement of €0.23/km or a fully covered NS Business Card
• Excellent pension scheme through the PME pension fund
• Work in an innovative, high-tech environment with real-world impact
• Open, informal company culture where your ideas are valued
• Lunch provided by DeltaQuad, monthly team drinks, and regular team activities
