ASTRIA HOLDINGS PTE. LTD. Hiring! Full Time Bio-Process Engineer - Bio-Process Technician (industrial waste recycling process) in East Region (Singapore), Earn up to SGD 3,700 - Ricebowl

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 roleinvolves 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

• 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.
• Ability to work independently and collaboratively in a multidisciplinary team environment.

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.
