Principal Mineral is seeking an experienced Mechanical Engineer to join our Engineering Team and deliver plant modernization and capital improvement projects. You’ll apply deep technical expertise and hands-on experience to ensure mechanical designs, specifications, vendor deliverables, fabrication approaches, and field execution plans are safe, technically sound, constructable, and cost-effective. This an onsite role located in Camden, South Carolina.

As the Mechanical Engineer, you will own mechanical systems from initial concept through final startup—covering design, specification, procurement support, installation coordination, and commissioning. You’ll partner across disciplines and with external vendors to support successful project delivery in industrial environments, with a focus on advanced manufacturing, automation, and continuous improvement.

Core Responsibilities

• Project planning & execution: Lead mechanical engineering scopes across project phases—from concept and feasibility through detailed design, procurement, fabrication, installation, and commissioning.

• Equipment specification: Specify and select industrial equipment such as pumps, boilers, chillers, compressors, and HVAC systems based on operating needs, performance requirements, and safety standards.

• Procurement & vendor management: Prepare mechanical equipment specifications and requisition packages, support technical bid evaluations, and assist with vendor selection.

• Design & code compliance: Review drawings and ensure mechanical systems meet applicable codes and regulations, including ASME, API, and local safety requirements.

• Cross-functional collaboration: Work with multidisciplinary EPC partners and internal teams (process, structural, piping, electrical, instrumentation, and construction management) to deliver integrated, buildable engineering packages.

• Technical documentation: Develop and maintain engineering drawings, specifications, and project documentation.

• Budget & timeline management: Track project costs and schedules to help ensure alignment with capital plans.

• Commissioning & safety reviews: Support checkouts, startup planning, and Pre-Startup Safety Reviews (PSSRs) to transition new installations safely into active plant operations.

Key Qualifications and Skills

• Technical knowledge: Deep technical knowledge and broad practical experience to ensure mechanical designs, specifications, vendor deliverables, fabrication approaches, and field execution plans are technically sound.

• Software proficiency: Strong experience with 2D and 3D modeling tools such as AutoCAD or SolidWorks.

• Education: Bachelor’s degree in mechanical, industrial, manufacturing, construction engineering, or a related field.

• Attention to detail: Demonstrated experience across the full capital project lifecycle—from concept and detailed design through procurement, fabrication, construction, commissioning, and Management of Change.

• Communication & organization: Strong written and verbal communication skills, with the ability to explain technical issues to both technical and business stakeholders.
