R&D Engineer

Position Overview

The R&D Engineer supports the development and scale-up of rare earth processing technologies, focusing on extraction, separation, and purification from primary and recycled feedstocks. This role is highly hands-on, bridging lab research and pilot plant operations to advance processes toward commercial readiness.

Key Responsibilities

• Design and execute experiments for rare earth leaching, solvent extraction, and purification.
• Translate bench-scale work into pilot-scale operations, supporting scale-up and process optimization.
• Operate and support pilot plant systems, including test planning, data collection, and troubleshooting.
• Perform mass balances and analyze process data to improve recoveries, efficiency, and product quality.
• Develop technical documentation (SOPs, PFDs, test reports) to support pilot operations and scale-up.
• Collaborate with engineering and operations teams to advance process design and commercialization.
• Support safety programs, including PHAs and compliance with environmental and operational standards.
• Coordinate with external partners (EPCMs, vendors, labs) as needed.

Qualifications

• Bachelor’s degree in Chemical, Metallurgical, or Materials Engineering (advanced degree a plus).
• 3–7 years of experience in hydrometallurgy, chemical processing, or process R&D.
• Experience with pilot plant operations and process scale-up.
• Familiarity with rare earth separation techniques (e.g., solvent extraction, precipitation) preferred.
• Strong data analysis, problem-solving, and process troubleshooting skills.
• Working knowledge of PFDs/P&IDs and process control systems (SCADA/DCS) is a plus.

Skills & Attributes

• Hands-on, execution-focused mindset suited for a pilot-stage environment.
• Ability to manage multiple priorities and adapt in a fast-paced setting.
• Strong communication skills and attention to detail.
