On-siteEngineeringFull-time

Duties and Responsibilities

  • Material Selection, Qualification & Behavior
  • Plan and execute material tests including tensile, creep, fatigue, thermal cycling, hardness, and corrosion/oxidation evaluations.
  • Use metallography, SEM/EDS, and other microstructural methods to understand material behavior and property changes under operating conditions.
  • Support nondestructive evaluation (NDE) approaches when required.
  • Additive Manufacturing Support
  • Assess metal powders, powder behavior, and printability for powder-bed and DED additive systems.
  • Work directly with AM engineers to connect material properties with parameter development, heat-treatment cycles, and post-processing requirements.
  • Verify that process changes, maintain material integrity and meet downstream performance demands.
  • Failure Analysis & Quality Control
  • Investigate component or material failures using microstructural analysis, fracture mechanics, and material degradation models.
  • Translate findings into improved designs, tighter process controls, or updated material specifications.
  • Research, Development & Process Improvement
  • Drive R&D efforts for next-generation materials suitable for high-efficiency distributed power generation.
  • Collaborate with design, thermal, combustion, and mechanical teams to create data-driven material strategies.
  • Improve welding, joining, heat-treat, and fabrication practices to increase durability and manufacturability.
  • Cross-Functional Collaboration & Documentation
  • Prepare clear technical reports, specifications, and test summaries.
  • Work with suppliers, powder vendors, and external labs to qualify materials and coatings.
  • Ensure all material documentation aligns with ASTM, ASME, and internal engineering standards.

Qualifications

  • Education, Experience and Certifications
  • Bachelor’s in metallurgical engineering or materials science degree required
  • 5+ years working with metals and materials characterization (graduate research counts).
  • Strong background in material behaviors such as fatigue, creep, oxidation, and thermal-mechanical degradation.
  • Experience supporting additive manufacturing materials or metal powder evaluation is strongly preferred.
  • Skills and Abilities
  • Hands-on experience with mechanical testing, microstructural evaluation, and failure analysis.
  • Understanding of how material properties change with heat treatment, AM process changes, or post-processing steps.
  • Familiarity with high-temperature alloys, surface treatments, coatings, and joining methods.
  • Ability to evaluate metal integrity when parameters or processes shift.
  • Strong analytical and problem-solving ability.
  • Clear, concise technical communication.
  • Comfortable working across disciplines (AM, thermal, mechanical, combustion, suppliers).
  • Detail-oriented with a research-driven mindset.
