About The Role

We are looking for an Manufacturing Process Engineer - Injection & Tooling with strong experience in injection molding or RTM to take ownership of scaling manufacturing processes from prototype to serial production.

You will design mould and tooling concepts, validate process parameters, and ensure robust, repeatable production at scale in a fast-moving industrial environment.

A key part of this role is leading the transition from early prototypes to stable, high-volume serial production, including tool validation, parameter optimization, and production readiness.

Are you excited to industrialize manufacturing processes and turn prototypes into stable serial production? Do you enjoy designing and optimizing molds, parameters, and cycle times until production runs reliably at scale? Do you thrive in a collaborative engineering team where your ideas quickly translate into production reality? Do you thrive in a collaborative engineering team where your ideas turn quickly into working solutions? Are you motivated by the opportunity to help shape the future of sustainable manufacturing — and make a real impact in the climate emergency? Then you will love Holy.

What You Will Do

Be part of a motivated engineering team to develop, industrialize, and automate the first upcyclable carbon fiber manufacturing technology.
Design, test, and validate resin injection processes for a range of composite components and material systems.
Build and operate injection setups in-house, from prototype molds to production-grade tooling.
Define, document, and optimize critical process parameters to ensure stable and repeatable serial production.
Work closely with automation engineers, designers, and technicians to develop robust, scalable processes for series production.
Develop advanced composite solutions tailored to customer needs — from one-off functional prototypes to high-volume, cost-efficient components.
Use the best equipment in our state-of-the-art workshop and lab to iterate quickly and test at industrial scale.
Share your process know-how across the team and help set technical standards for our robotic production system.

This role can grow into an expert, generalist, or team lead position — and we'll regularly align on your personal development goals.

What We Are Looking For

You have 2+ years of hands-on experience in injection molding, RTM, or comparable high-volume manufacturing environments.
You've worked in fast-paced environments — ideally in automotive, aerospace, or high-performance composites production
You enjoy collaborating with engineers, designers, and technicians to solve real-world production challenges.
You have an autonomous, hands-on working attitude and enjoy building things yourself.
You understand industrial manufacturing processes end-to-end — from tooling design and mold trials to stable serial production.
You're motivated to help move from prototype to production and build robust, scalable processes.

You're curious about new materials, tooling concepts, and injection techniques, and want to help define best practices in a young, growing company.

You thrive in an agile, fast-moving environment where results matter more than titles.

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.

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.
