Product Developer; f​/m​/x in Film Extrusion technologies

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
, youdevelop 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.

• University degree in polymer science, material science, chemical engineering or similar with an applied research mindset.
• You have 5+ years
  of experience in biopolymer-based product
  and features develop ment.
• You have 5+ years of technical experience in the (bio) polymer converting industry with a specialization in film extrusion
  processes.
• Strong technical understanding
  of natural polymer structures, interactions, processing techniques and polymer compounds.
• Hands-on mentality and a solution-oriented mindset
  .
• Proven track record of delivering projects on time
  from concept to implementation,and at the required quality standards
  .
• Excellent decision-making
  skills and analytical thinking
  , with the ability to manage complexity and ambiguity.
