We are seeking a Senior Design & CFD Engineer to lead the development, validation, and optimization of digital twin models for our internally designed atomization systems. This is a high-impact role requiring deep expertise in fluid dynamics, mechanical design, and system-level engineering. The right candidate will take full ownership of modeling and design efforts that directly influence system performance and next-generation technology development.

The Senior Design & CFD Engineer will design, analyze, and optimize complex mechanical systems used in advanced metal processing applications. This role combines hands-on mechanical design with advanced multi-physics simulation (CFD), focused on high-temperature gas flows, controlled atmospheres, and vacuum systems.

The ideal candidate is a technically strong, self-directed engineer who thrives in a fast-paced, collaborative environment and can drive projects from concept through production with minimal oversight.

Key Responsibilities

Digital Twin & CFD Leadership

  • Develop, validate, and continuously improve multi-physics CFD models using Ansys Fluent (or similar platforms).
  • Simulate high-temperature gas flows involving multiple inert gases, subsonic and supersonic velocities, and vacuum conditions.
  • Model complex thermo-fluid interactions relevant to metal atomization processes.
  • Translate simulation results into actionable design improvements and performance optimization strategies.

Mechanical Design & System Development

  • Design and detail mechanical systems and subassemblies including weldments, piping, pressure systems, hydraulics, pneumatics, and motion systems.
  • Develop robust design concepts and detailed fabrication drawings aligned with performance, safety, and manufacturability requirements.
  • Perform extensive 3D CAD modeling and 2D detailing (SolidWorks preferred).
  • Ensure design integrity through verification, peer reviews, and adherence to engineering standards.

Cross-Functional Collaboration & Execution

  • Collaborate with engineering, manufacturing, procurement, and project management teams to ensure seamless design integration into production.
  • Provide technical leadership during drafting, fabrication, and system commissioning phases.
  • Support supplier selection and purchasing by defining technical requirements and evaluating capabilities.
  • Manage assigned design projects, including cost estimation, scheduling, and progress tracking.
  • Troubleshoot design and production challenges, implementing practical, data-driven solutions with accountability for results.

Required Qualifications

  • Bachelor’s degree in mechanical engineering (BSME) or equivalent required.
  • 5+ years of experience in mechanical system design.
  • Demonstrated experience with CFD modeling of thermo-fluid systems.
  • Experience working with vacuum systems, controlled atmospheres, high-temperature gas systems, or similar environments.
  • Strong proficiency in SolidWorks (or comparable 3D CAD platform).
  • Strong proficiency in Ansys Fluent or comparable CFD software.
  • Working knowledge of GD&T (Geometric Dimensioning & Tolerancing).
  • Familiarity with metals including carbon steel, stainless steel, copper, brass, aluminum, and engineering plastics.
  • Understanding of fabrication and joining methods: welding, threading, forming, brazing.
  • Experience integrating motors, sensors, actuators, hydraulics, and pneumatics into mechanical systems.
  • Proficiency in Microsoft Office and engineering documentation tools.

Preferred Qualifications

  • Experience in metal atomization, powder processing, or additive manufacturing.
  • Experience developing and maintaining digital twin models.
  • Experience working in startup or fast-growth environments.
  • Master’s degree in mechanical engineering or related field (CFD focus a plus).

Desired Candidate Qualities

  • Strong analytical and problem-solving capabilities for complex, multidisciplinary challenges.
  • Ability to clearly communicate technical findings to both engineering and non-technical stakeholders.
  • High level of ownership and accountability.
  • Organized, detail-oriented, and quality-driven.
  • Adaptable and comfortable working in a dynamic, evolving technical environment.

Work Environment & Physical Requirements

  • Primarily office-based with periodic time on the manufacturing floor.
  • Ability to sit, stand, walk, and bend for extended periods.
  • Occasionally required to lift or move up to 25 lbs.
  • May be required to reach, climb, balance, stoop, kneel, crouch, or crawl.
  • Requires close vision, color vision, and depth perception.

Travel:

Occasional domestic travel may be required.
