Hardware Engineering Intern (m/f/d)

Location: Berlin / Hybrid

Duration: By arrangement

Start: As soon as possible

We are a Berlin-based defense deep-tech startup developing mission-critical systems for defense against drones, missiles, and other airborne threats.

Our systems combine mechanical engineering, electronics, software, and sensing, and must perform reliably under real-world operational conditions.

As an early-stage company, we operate with high speed, close team collaboration, and a strong focus on technical excellence and ownership.

As a Hardware Engineering Intern, you will actively contribute to the development of our hardware systems. You will support both conceptual work and hands-on implementation, including simulation, prototyping, and testing.

This role is ideal for students who are interested in real-world engineering systems and want to work not only theoretically, but also practically with hardware.

• Contribute to the design and development of mechanical or electromechanical components
• Support CAD modeling, design iterations, and detailed engineering work
• Assist with FEM and thermal simulations and help interpret results
• Support the setup, integration, and validation of prototypes
• Plan, build, and document test setups and experimental series
• Collaborate closely with adjacent teams in electronics, embedded systems, and software
• Contribute to additive manufacturing / 3D printing (metal, plastics, carbon), from part preparation to evaluation of form, function, and manufacturability

• Currently enrolled in Mechanical Engineering, Mechatronics, Aerospace Engineering, or a related field
• Strong interest in design, prototyping, validation, and interdisciplinary system development
• Initial experience with CAD is helpful but not required
• Independent working style, solid technical understanding, and strong willingness to learn
• Motivation to work hands-on with hardware

• First experience with simulation, manufacturing, or lab work
• Experience with 3D printing, CNC machining, workshop work, or mechanical integration

• A paid internship with real responsibility rather than purely supportive tasks
• Hands-on experience building real-world defense hardware systems
• Close collaboration within a highly technical, interdisciplinary team
• High ownership and responsibility from early on
• Fast-paced startup environment with strong learning opportunities
• Hybrid work setup based in Berlin

• Hands-on and practical: You enjoy working directly with hardware and prototypes
• Curious and eager to learn: You actively seek to deepen your technical skills
• Structured and reliable: You work independently and follow through on tasks
• Collaborative: You enjoy working across disciplines with different teams
• Ownership-driven: You take initiative and responsibility for your work
