Job Description

Job Summary

We are seeking a motivated Bio-Process Engineer/Technician to support the development and scale-up of bioleaching processes for the recycling of industrial waste using bacteria or other microorganisms. The role involves conducting laboratory- and pilot-scale experiments, managing process flows to produce pregnant leach solutions, and evaluating key technical parameters to support process optimization and scale-up.

Key Responsibilities

Design and conduct laboratory-scale experiments on the bioleaching of industrial waste using bacteria or other microorganisms.
Prepare, operate, and monitor bioleaching systems (e.g., flasks, bioreactors, leaching columns) under controlled conditions.
Handle and manage the overall process flow from feedstock preparation through bioleaching to obtain pregnant leach solutions (PLS).
Monitor and analyze critical process parameters such as pH, temperature, redox potential, microbial activity, metal recovery rates, and leaching kinetics.
Scale experiments from laboratory scale to pilot-line level, evaluating process performance, reproducibility, and scalability.
Collect, analyze, and document experimental data to support process optimization and decision-making.
Assist in the development, improvement, and standardization of bioleaching protocols and operating procedures.
Ensure compliance with laboratory safety, biosafety, chemical handling, and environmental regulations.
Support cross-functional or ad hoc projects related to bio-process development, equipment trials, or technology evaluation as assigned.

Qualifications & Requirements

Diploma or Bachelor's degree (or equivalent) in Bioprocess Engineering, Biotechnology, Microbiology, Chemical Engineering, Metallurgical Engineering, or a related field. 1-2 years experience preferred. Fresh graduate are also welcome to apply.

Hands-on experience with microbial processes, fermentation, bioleaching, or related biochemical/bioprocess operations.
Familiarity with laboratory-scale bioreactors, process monitoring, and analytical techniques.
Understanding of mass balances, process flows, and basic scale-up principles.
Strong experimental, analytical, and documentation skills.

. Proficiency in Mandarin Chinese would be advantageous, as the position requires regular communication with China-based team members who primarily communicate in Mandarin Chinese.

. Willingness to undertake business travel when required, including travel arranged at relatively short notice.

. Ability to handle and move raw materials and laboratory/process materials weighing up to approximately 10 kg.

Preferred Skills (Optional)

Experience with hydrometallurgy, metal recovery, or recycling of electronic waste or batteries.
Experience in pilot-scale operations or technology scale-up.
Knowledge of process control, data analysis tools, or process simulation.
Exposure to GLP, GMP, or industrial R&D environments.
