Mechanical Engineer

Role Overview

Mariana Minerals is looking for a highly motivated Mechanical Engineer with experience in civil, structural, piping, or static equipment engineering and design. Mariana Minerals is building the critical minerals supply chain to support the world’s energy transition.

As a Mechanical Engineer at Mariana Minerals, you will lead the development and deployment of first-of-its-kind chemical refining processes, while also supporting development of software for capital project execution and automated plant optimization. Responsibilities will include leading basic and detailed engineering strategies, managing external engineering firms, staff-aug contractors, and internal teams, developing issued-for-construction engineering packages for civil, structural, piping, and static equipment scopes.

What You’ll Do

• Lead mechanical, civil, structural, or piping engineering scopes from concept and preliminary design through detailed engineering, procurement, and construction

• Develop engineering deliverables such as:

  • Equipment plot plan and layout drawings

  • Civil foundation design packages

  • Stormwater management design packages

  • Structural steel design packages

  • Piping isometrics

  • Bill of Materials (BOMs), specifications, and data sheets

• Perform and review detailed calculations for equipment supports, structural members, and piping systems under various load conditions.

• Support field implementation through construction support, RFIs, and redlines to as-built packages.

• Coordinate with external engineering partners, vendors, and contractors to deliver safe, high-quality, and cost-effective engineering solutions.

• Integrate work with cross-functional teams including process engineering, project execution, controls, software, and operations teams to ensure successful implementation of refining infrastructure.

• Support constructability and value-engineering efforts to reduce cost and accelerate project timelines.

What You’ll Bring

• Strong understanding of engineering fundamentals and demonstrated ability to leverage the understanding to solve challenging problems

• A strong foundation in mechanical, civil, structural, or piping engineering with a demonstrated ability to apply first principles to solve complex design and field challenges

• Familiarity with relevant codes and standards (e.g., ASME, API, AISC, ASTM, CSA).

• Strong proficiency with engineering design tools such as:

  • AutoCAD

  • SolidWorks

  • Compress

  • CAESAR II

  • STAAD Pro

  • ANSYS Mechanical

  • IDEA Statica

  • FE PIPE/NOZZLE PRO

  • MECASTACK

  • L-Pile

• Experience with equipment engineering and design. Including but not limited to:

  • Brownfield equipment modifications and upgrades

  • Greenfield equipment design

  • Evaluation and optimization of operating equipment

• Experience with the following industries and/or production environments:

  • Industrial manufacturing

  • Large-scale mining or mineral processing

  • Large-scale chemical production processes

  • Engineering, procurement, and construction firms
