Bio-Process Engineer / Bio-Process Technician

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.
