About The Position

Kunin Technologies is hiring a Process Engineer to carry the engineering of metal recovery projects from flowsheet development through drawings, engineering packages, pilot operations, and plant start-up. Working under the Principal Process Engineer, the role turns metallurgical results into process designs and supports projects from pilot through commercial scale. The Process Engineer develops and maintains flowsheet models, including mass and energy balances, water balances, reagent consumption, and techno-economic models used for Go/No-Go decisions. The role authors process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs), equipment lists, and process datasheets; sizes and specifies hydrometallurgical unit operations; designs and runs pilot campaigns; and uses pilot data to establish scale-up parameters. The position also supports FEED and detailed engineering with EPCM partners, commissioning and start-up through nameplate, and preparation of operating procedures. The position is based in Chattanooga, Tennessee. The successful candidate must be willing to relocate there and travel to customer and partner sites in the United States, Canada, Brazil, South Africa, and Australia. Extended hours and weekends are frequently required to support critical project milestones. Relocation support will be provided. Kunin states it will do what it can to secure work authorization for the right candidate.

Requirements

Bachelor's degree in chemical or metallurgical engineering.
3 to 7 years of process engineering experience in hydrometallurgy, chemicals, or minerals processing.
Skill in flowsheet mass-balance and techno-economic modeling using METSIM, SysCAD, Aspen, or a well-built spreadsheet.
Experience authoring PFDs, P&IDs, and equipment specifications for a plant that was built, or willingness to learn by doing so at Kunin.
Comfort working in both a laboratory and on a plant floor, including running a column, reading a level transmitter, and updating a P&ID.
Willingness to work hard in an early-stage startup environment with high autonomy, opportunity, and expectations.
Strong communication skills, including the ability to write a design basis that an EPCM partner can build from and a stage-gate memo that a CEO can use to make decisions.
Willingness to relocate to Chattanooga, Tennessee.
Availability to travel to customer and partner sites across the United States, Canada, Brazil, South Africa, and Australia.
Availability for extended hours and weekends, frequently required for critical project milestones.

Responsibilities

Develop and maintain flowsheet models, including mass and energy balances, water balance, reagent consumption, and techno-economic models for Go/No-Go decisions.
Author PFDs, P&IDs, equipment lists, and process datasheets for pilot and commercial-scale projects.
Size and specify unit operations, including leach reactors, thickeners and filters, ion-exchange and solvent-extraction circuits, precipitation and crystallization, and electrowinning.
Design, build, and run pilot campaigns with the metallurgy team, and translate pilot data into scale-up parameters.
Support FEED and detailed engineering with EPCM partners by reviewing vendor packages, answering process questions, and maintaining the design basis.
Support commissioning and start-up through nameplate.
Write plant operating procedures.
Travel to customer and partner sites for testing, engineering, and start-up.
