CAD Engineer Intern / Working Student (m/f/x)

About The Role

We are looking for a CAD & Tooling Engineering Intern / Working Student(m/f/x) to help design and optimize the tools and molds that power Holy’s autonomous composite manufacturing technology. You will work at the intersection of CAD engineering, tooling development, and advanced fabrication, contributing to both digital design and hands-on manufacturing.

Do you enjoy precise engineering work, improving design workflows, and experimenting with new methods such as parametric modeling or design automation? Do you want to gain real experience by building what you design? Then you will thrive at Holy.

What You Will Do

• Support the design of molds, tools, and manufacturing fixtures for our proprietary composite production processes.
• Create and refine CAD models in SolidWorks and Rhino, ensuring manufacturability and alignment with process requirements.
• Help optimize and automate design workflows, including parametric modeling and repeatable design templates.
• Collaborate with our toolmaking and production teams to translate CAD designs into real components.
• Participate in the manufacturing of your own designs using 3D printing, CNC machining, and other advanced fabrication methods.
• Contribute to standardizing how tooling and mold designs are created, documented, and prepared for production.
• Work closely with engineers across development, tooling, and manufacturing to improve design quality and process efficiency.
• OPTIONAL: Write your Master thesis with us on mold design, process optimization, or CAD workflow automation.
  
  

What We Are Looking For

• You are pursuing a Master’s degree in Mechanical Engineering or a related technical field, or you have completed a training as a Technische/r Produktdesigner/in and want to gain experience in tooling and CAD engineering.
• You are fluent in SolidWorks and can create clean, structured CAD models.
• You are familiar with Rhino and comfortable working with freeform geometries.
• You enjoy engineering-focused design work and think about manufacturability and process efficiency.
• You are curious about design automation, parametric modeling, and more efficient CAD workflows.
• You enjoy hands-on work and like being part of the manufacturing of your own designs (3D printing, CNC machining).
• You are familiar with design for additive manufacturing and have worked with 3D printing technologies before.
• You work proactively and in a structured, step-by-step manner.
• You collaborate well with engineers, designers, and production teams.
• You feel comfortable communicating in English in an international work environment.
• PLUS: Experience with Grasshopper for parametric/automated CAD workflows.
• PLUS: Basic experience with CAM programming or CNC machining.
  
  

You do not tick all the boxes? We are looking for driven candidates who most importantly add to our culture, and don’t just blend in. Feel free to submit an Unsolicited Application if you believe you are a fit.

What We Care About

• Honesty: Being authentic and honest creates trust toward colleagues, customers, and business partners.
• Optimism: Positivity is the fuel for all good decisions. Smile and spread positivity in the workplace. Do not take yourself too seriously and treat others with respect.
• Focus: Always separate unimportant from important. Focus on the impactful actions that lead to impactful results.
• Courage: Courage is the source of any big success. Stand up for your ideas, no matter how bold.
• Sustainability: Do it nice or do it twice. Consider the future consequences of your actions holistically.
• We win and fail together: Fail early, fail often, fail forward. Failure is where the lessons are. We overcome challenges as a team.
  
  

What We Offer

• Impact: Work on a meaningful solution in the fight against climate change with us.
• Growth: Learn from experienced colleagues, grow your knowledge, and expand your skills within your field or by entering new ones.
• Ownership: Take ownership and meaningfully shape an early-stage company.
• Competitive compensation: We believe in rewarding good work.
• Equity: We want you to become a part of us.
• Additional perks: We cover 50% of your costs for fitness (Wellpass), language courses, and the German public transport ticket.
• Pick your poison: Use the technical equipment of your choice including a meaningful home office set-up.
• Fun place to work: Enjoying work is crucial for us.
  
  

About Us

Holy Technologies pioneers autonomous composite manufacturing to help manufacturers build radically better lightweight components.

We are a European contract manufacturer specialized in ultralight load-bearing composite parts for automotive, aerospace, robotics and industrial manufacturing. Our proprietary Infinite Fiber Placement (IFP) technology enables cost-competitive production at mid-to-high volumes, delivering aramid and carbon fiber components that are fast to produce, scalable, and fully recyclable.

IFP places continuous dry fibers along load-optimized trajectories calculated by proprietary software. This process delivers parts at minimum weight with enhanced mechanical performance.

From prototypes to series production, we help teams move from CAD to finished parts in weeks instead of months, allowing our customers to innovate faster and stay ahead of competition.
