Technical Specialist

We are seeking an experienced and motivated Chemical Engineer to lead the development, optimization, and scale-up of hydrometallurgical and chemical separation processes. This role is centered on complex solid–liquid systems, including acid leaching, impurity removal, crystallization, and downstream solids handling, supporting the production of high-purity chemical and materials products.

What You’ll Do 

As a Chemical Engineer, you will be responsible for the end-to-end design and improvement of integrated chemical processing flowsheets, with a strong emphasis on separation science and scale-up:

Process Design & Optimization

• Lead the design, development, and optimization of hydrometallurgical and chemical processing flowsheets, including acid leaching, solid–liquid separation,

solution purification, and crystallization.

• Define process operating windows to maximize recovery, purity, and/or throughput

while minimizing reagent consumption and waste generation.

Leaching & Reaction Engineering

• Develop and model leaching and dissolution processes for mineral or solid feedstocks, evaluating kinetics, mass transfer, and impurity behavior.

• Optimize reaction conditions to enhance target species extraction while controlling co-dissolution of unwanted elements.

Solid–Liquid Separation

• Design and optimize solid–liquid separation operations such as thickening, filtration, washing, and clarification.

• Troubleshoot issues related to particle size distribution, settling behavior, filtration

performance, and solids losses.

Purification & Separation

• Develop and refine impurity removal strategies using techniques such as

precipitation, solvent extraction, ion exchange, or selective crystallization.

• Achieve stringent purity specifications through robust and scalable separation

schemes.

Crystallization & Solids Processing

• Design and optimize crystallization systems, including control of supersaturation, temperature profiles, residence time, and crystal morphology.

• Support downstream solids processing steps such as drying, calcination, or thermal

treatment as required by the product.

Troubleshooting & Continuous Improvement

• Act as a technical authority for diagnosing and resolving complex plant issues, including fouling, corrosion, impurity buildup, yield loss, characterization, and

operability challenges.

• Drive continuous improvement initiatives across safety, reliability, and process performance.

Safety, Compliance & Documentation

• Ensure all process designs and operations comply with safety, health, and environmental regulations.

• Prepare technical reports, process documentation, economic evaluations, and support intellectual property development.

What We’re looking For

• Bachelor’s degree or higher in Chemical Engineering, Metallurgical Engineering, or a related discipline.

• 5 years of progressive experience in process engineering, including hands-on

experience in chemical, hydrometallurgical, or minerals processing operations (academic experience doesn’t count towards this).

• Strong expertise in acid leaching, solid–liquid separation, and purification technologies.

• Demonstrated experience with chemical crystallization processes and solids-forming systems.

• Familiarity with processing mineral, industrial, or inorganic solid feedstocks is highly desirable.

• Experience with high-purity or specialty chemical/materials production is an asset.

• Proficiency in process simulation and modeling tools (e.g., Aspen Plus, HSC Chemistry) and data analysis.

• Proven ability to lead complex technical projects, solve multidisciplinary problems, and support process scale-up.

• This role requires extensive R&D lab/pilot work for the first 6 months, physical ability to carry out long experiments/process runs, and full ownership to meet the deadlines.
