Construction, HSE & Commissioning Support

• Provide mechanical engineering support during construction, equipment installation, pre-commissioning and commissioning.
• Review equipment erection, alignment, inspection and testing requirements.
• Participate in HAZID, HAZOP and technical risk assessment workshops.
• Ensure that equipment design considers occupational safety, accessibility, lifting operations, wear resistance, corrosion and maintenance requirements.
• Support the resolution of site technical queries, non-conformities and engineering modifications.
• Contribute to mechanical completion activities and commissioning readiness.

Project Performance

• Support engineering schedules, resource estimates and technical progress reporting.
• Contribute to project cost estimates and CAPEX assessments for mechanical equipment and installations.
• Identify risks associated with long-lead equipment, engineering interfaces and design changes.
• Report technical progress, challenges and recommendations to the Engineering Manager.

Education & Professional Background

• Bachelor's or Master's degree in Mechanical Engineering.
• Minimum 10 years of professional experience in mechanical engineering, preferably within mining, mineral processing, heavy industry or large-scale EPC/EPCM projects.
• Demonstrated experience in the engineering and design of mechanical equipment for mining and mineral processing operations.
• Experience supporting construction, equipment installation or commissioning activities is highly desirable.
• Professional engineering registration with ECN Namibia, ECSA or an equivalent professional body would be an advantage.

Technical Expertise

• Strong technical knowledge of crushing, conveying, stacking, bulk material handling, pumping, agitation, tanks and industrial piping systems.
• Proven experience reviewing detailed engineering documentation and mechanical design packages.
• Good understanding of international engineering codes and standards, including ISO, ASME, API, EN and SANS.
• Experience working with EPC/EPCM contractors, equipment suppliers and multidisciplinary engineering teams.
• Knowledge of mechanical inspection and quality assurance processes, including ITPs, FAT, welding and NDT.
• Familiarity with 3D engineering models and mechanical design review tools.
• Understanding of equipment reliability, maintainability, abrasion, corrosion and mechanical integrity.
• Knowledge of Namibian technical regulations would be an advantage.
• Previous experience in nuclear facilities, uranium mining or radiologically controlled environments would be a strong asset.

Personal Skills

• Excellent technical analysis and problem-solving abilities.
• Strong organizational and coordination skills.
• Ability to manage multiple engineering interfaces and priorities.
• Autonomous, proactive and results-oriented approach.
• Excellent communication skills and ability to work effectively in multicultural environments.
• Fluent English, both written and spoken. French would be an advantage.
• Valid driver's license.
