Senior Process Engineer – Gold Processing

Location: Arizona / Nevada, USA

Project: $4B World-Class Gold Mining Project

We are seeking an experienced Senior Process Engineer to join a major EPCM-led $4B gold mining project in Nevada. This is a key technical role responsible for leading process development, metallurgical evaluation, and engineering studies across the project lifecycle, supporting the successful delivery of a large-scale gold processing operation.

The successful candidate will play a critical role in the development, optimisation, and technical assurance of process flowsheets, working across scoping, pre-feasibility (PFS), feasibility (FS), and detailed engineering phases . This position requires strong expertise in gold processing, metallurgical test work interpretation, and the development of practical, operable process solutions.

Key Responsibilities

- Lead process development and engineering studies for gold processing facilities, ensuring technical integrity and alignment with project objectives.
- Develop, review, and optimise process flowsheets, mass balances, PFDs, P&IDs;, and process design criteria .
- Interpret and integrate metallurgical test work data into process design and engineering deliverables.
- Support engineering studies including trade-off assessments, process simulations, equipment sizing, and technical evaluations .
- Collaborate with multidisciplinary engineering teams including metallurgy, mechanical, piping, electrical, civil, and project controls to deliver integrated project outcomes.
- Provide technical input into CAPEX/OPEX estimates,



risk assessments, and project execution strategies .
- Support process plant design with a focus on gold recovery, crushing, grinding, flotation, leaching/CIL/CIP, elution, detoxification, and tailings systems .
- Participate in HAZOPs, design reviews, and value engineering workshops to ensure safe, efficient, and operable plant solutions.
- Mentor junior engineers and contribute to technical excellence across the process engineering team.

Requirements
- Bachelor’s degree in Chemical Engineering, Metallurgical Engineering, Mineral Processing, or related discipline .
- Significant experience as a Process Engineer within gold or precious metals processing projects , ideally in an EPCM environment.
- Strong experience delivering engineering studies across Scoping, PFS, FS, and execution phases .
- Proven knowledge of gold process plant design and process optimisation .
- Experience with metallurgical test work programs, process modelling, and equipment selection .
- Strong stakeholder engagement and communication skills, with the ability to work across multidisciplinary project teams.
- Experience on large-scale mining capital projects is highly desirable.

Why Join? This is an chance to play a leading technical role on one of the mining sector’s most significant gold developments , contributing to the successful delivery of a major, long-life operation while working alongside an experienced project team.

Interested candidates are encouraged to apply. EPCM project experience is strongly preferred.
