Product Developer (f/m/x) in Film Extrusion technologies

Permanent employee, Full-time · Hamburg-Harburg (Neuland)

Your mission

We’re solving global plastic pollution – and you can be part of the solution!

With our groundbreaking technology, we transform agricultural plant residues into an innovative and environmentally friendly biomaterial – bio-based, plastic-free, and compostable. A material that leaves no harmful traces. Our goal is to replace as much conventional plastic as possible – and that’s where you come in.

As Product Developer (f/m/x) in Film Extrusion technologies, you develop and optimize traceless’ innovative and holistically sustainable film products, ensuring they run robustly on extrusion lines and meet functional, quality and sustainability requirements. You will drive the advancement and optimization of our material technologies and products, to help us enable a transition to use traceless products for a maximum array of applications and make the biggest possible contribution to solving global plastic pollution.

Your responsibilities:

Develop, scale and optimize film formulations based on traceless materials for blown and/or cast film extrusion (e.g. packaging, single-use items, etc.).
Design structured experiment plans, document all trials and evaluate data to derive clear development directions.
Coordinate and perform material and film testing (e.g. tensile, puncture, tear, thickness profile, optical properties, barrier and sealing tests) together with internal labs and external partners.
Investigate relationships between material structure, processing conditions and film properties, and feed results back into formulation and process design.
Translate application requirements (e.g. mechanical strength, barrier, sealability) into film structure, recipes and process settings.
Plan, execute and evaluate lab-, pilot- and production-scale extrusion trials, in collaboration with our Application Engineers.
Create and maintain technical documentation for products and processes (specifications, test plans, trial reports, SOPs, scale-up reports).
Prepare and accompany scale-up and validation runs on internal and customer extrusion lines.
Collaborate cross-functionally with other groups to align on capabilities, customer needs, compliance and product implementation.

You will spend your working days in an innovative work environment with start-up flair in our laboratory in Harburg, Hamburg.
