Position Overview:

LiquidPiston is seeking a Metallurgical Engineer to lead materials-focused efforts in support of engine design, development, and testing. This hands-on role is critical to enhancing performance, durability, and manufacturability of engine components operating under extreme mechanical and thermal stresses. The ideal candidate will have deep expertise in metallic materials and coatings, a strong understanding of tribology and fatigue behavior, and the ability to translate theoretical knowledge into practical design and manufacturing decisions.

Responsibilities:

• Guide materials selection and processing for high-performance engine components, including rotating and reciprocating parts
• Evaluate and implement surface treatments, coatings (PVD/CVD, HVOF, plating), and thermal barrier solutions
• Lead tribological analysis and make recommendations for improving wear resistance in lubricated engine environments
• Oversee and maintain the metallurgy lab, including heat-treat ovens, hardness testers, microscopes, and wear testing equipment
• Support engine test programs through inspection, failure analysis, and post-test component evaluation
• Collaborate with internal teams and external specialists (e.g., gear, seal, and coating vendors) to solve material challenges
• Act as the primary technical contact for raw material and coating suppliers
• Create and enforce standardized procedures for material selection, treatment, and documentation
• Present findings, material analyses, and recommendations to technical and executive teams
• Proactively contribute to R&D efforts by inventing and evaluating new material solutions that enhance performance, manufacturability, or cost-effectiveness
• Maintain an adaptive, solution-focused mindset to tackle the unique challenges of novel engine development

• MS or higher in Materials Science, Metallurgical Engineering, or related field
• 5+ years of professional experience in materials selection, processing, and testing
• Expertise with metallic materials such as aluminum, steel, magnesium, titanium, and MMCs
• Strong knowledge of tribology, fatigue analysis, and failure mechanisms relevant to mechanical systems and engines
• Familiarity with thermal barriers, welding, and joining technologies for dissimilar metals
• Experience with both traditional and modern manufacturing methods for precision metal components
• Demonstrated ability to work independently and lead technical efforts across disciplines
• Hands-on experience with post-service failure analysis and report writing

• Experience with engine development or rotating machinery
• Familiarity with CAD tools (e.g., SolidWorks) and mechanical simulation tools (ANSYS, MATLAB)
• Experience in R&D or prototype development environments
• Strong communication skills, including technical writing and presenting findings to diverse teams

• Flexible PTO to encourage work-life balance and personal well-being
• Comprehensive healthcare coverage: medical, dental, and vision plans
• Equity participation: RSUs for all permanent employees
• 401(k) with match: 100% up to 3%, plus 50% match for 3-5% range
• Growth opportunities: Mentorship, training, and leadership development

At LiquidPiston, we challenge convention and solve hard problems. We move fast, think boldly, and iterate quickly. Our team thrives on collaboration, creativity, and resilience. We take calculated risks and believe that every setback is a steppingstone toward breakthrough innovation.
