Job summary

LiquidPiston, Inc. seeks a Metal Additive Manufacturing Designer/Modeler to join our R&D team in Bloomfield, CT.

The role combines simulation, design, and direct manufacturing work to push the performance and weight targets of next‑gen rotary engines through topology optimization and AM processes. You will develop solid models, run FEA/CFD analyses, and validate designs with additive builds, collaborating with mechanical, thermal, and manufacturing engineers.

Qualifications

• 3+ years of professional experience in product design, simulation, and/or manufacturing.
• Expertise in additive manufacturing methods (e.g., DMLS, SLS, Binder Jetting).
• Proficiency in topology optimization tools (nTop preferred) for structural, thermal, and fluid systems.
• Strong 3D CAD skills (SolidWorks or equivalent).
• Simulation experience with ANSYS or similar FEA/thermal software.
• Deep understanding of materials science, especially metallurgy as it pertains to AM.

Responsibilities

• Apply topology optimization and AM methods to design lightweight, high-performance engine components.
• Use nTop or similar software to optimize structural, thermal, and fluid features.
• Develop and refine solid models and assemblies tailored for AM processes.
• Collaborate with mechanical, thermal, and manufacturing engineers to integrate optimized parts into complete engine systems.
• Analyze designs using simulations (FEA, CFD, thermal) and correlate with physical test data.
• Oversee additive builds from design validation through manufacturing and post-processing.
• Innovate new design approaches to improve performance, reduce weight, and streamline manufacturing.
• Support engine testing and contribute insights based on material behavior and part performance.
• Maintain clear documentation, share findings in presentations, and contribute to design reviews.
• Uphold a proactive, problem-solving mindset with a collaborative and resilient approach to technical challenges.
