Vollständige Stellenbeschreibung

Overview

BIOWEG is seeking a motivated student assistant (Werkstudent/in) to support the bioleaching and hydrometallurgical work within the BIOPEPLEACH project. You will work closely with the Project Engineer and collaborate with academic partners at TU Berlin.

This is a hands-on laboratory role. You will be assisting in leaching experiments, preparing samples for analysis, maintaining lab equipment, and contributing to literature review.

Your Role

Laboratory work (primary focus):

Hands-on experience in a chemical laboratory.
Preparation of feedstock samples for leaching experiments
Setting up experiments for leaching and filtration.
Recording experimental parameters: pH, ORP/Eh measurements, temperature logging, sampling at defined time intervals
Prepare samples for ICP-OES/ICP-MS/HPLC/IC analysis
Maintenance of laboratory equipments like pH meters, ORP probes, and titration equipment
Prepare calibration standards and reagent solutions

Data and documentation:

Analyze and extract important, applicable data from research papers.
Maintain clean, organized lab documentation following SOPs

Your Profile

Currently enrolled in a Bachelor's or Master's program in Chemistry, Chemical Engineering, Materials Science, Metallurgy, Process Engineering, Environmental Engineering, or a related field
Basic understanding of solution chemistry: pH, acid-base equilibria, precipitation reactions
Understanding of hydrometallurgical concepts is an advantage
Interest in sustainability, circular economy, and critical raw materials
Hands-on laboratory experience (from coursework, internships, or thesis work)
Careful, systematic working style with attention to detail and reproducibility
Reliable, self-organized, and able to work independently after initial training
Ability to work independently and collaboratively in a fast-paced startup
Good written and verbal communication skills in English (working language of the project); Fluency in German is a plus

What We Offer

Hands-on involvement in a project at the intersection of biotechnology and hydrometallurgy
Collaboration with academic partners at TU Berlin (UniSysCat Cluster of Excellence)
Practical experience with industrial-relevant analytical techniques (ICP, HPLC, titration)
Mentorship from an experienced process engineer with pilot-scale REE separation expertise
Flexible hours compatible with your study schedule
Potential for the role to develop into a thesis project (Bachelor's or Master's)
