Metal Additive Manufacturing Designer/Modeler

LiquidPiston•Suffield, CT

7d•Onsite

About The Position

LiquidPiston is seeking an Engineer with a strong background in additive manufacturing and topology optimization to join its R&D team. The role transforms rotary engine designs using computational design methods and manufacturing technologies, working across simulation, design, and manufacturing to improve performance and efficiency. It is a hands-on position in a fast-paced development environment. The role is fully onsite in Bloomfield, Connecticut, five days per week. The company plans to relocate to Suffield, Connecticut, later in 2026.

Requirements

Bachelor’s degree or higher in Mechanical Engineering or a related field.
At least 3 years of professional experience in product design, simulation, and/or manufacturing.
Expertise in additive manufacturing methods such as DMLS, SLS, or Binder Jetting.
Proficiency with topology optimization tools for structural, thermal, and fluid systems; nTop is preferred.
Strong 3D CAD skills, such as SolidWorks or equivalent.
Simulation experience with ANSYS or similar FEA/thermal software.
Deep understanding of materials science, especially metallurgy as it relates to additive manufacturing.
Ability to work independently and solve complex, cross-disciplinary problems.

Nice To Haves

Experience with internal combustion engines, compressors, or advanced thermodynamic systems.
Knowledge of GT-Suite, MATLAB, Python, or other engineering simulation or scripting tools.
Experience in a prototype or R&D environment.
Strong written communication skills, including proposal and technical report writing.
Familiarity with quality control and inspection processes for additive parts.

Responsibilities

Apply topology optimization and additive manufacturing methods to design lightweight, high-performance engine components.
Use nTop or similar software to optimize structural, thermal, and fluid-related features.
Develop and refine solid models and assemblies tailored for additive manufacturing processes.
Collaborate with mechanical, thermal, and manufacturing engineers to integrate optimized parts into complete engine systems.
Analyze designs using FEA, CFD, and thermal simulations, and correlate results with physical test data.
Oversee additive builds from design validation through manufacturing and post-processing.
Develop 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, present findings, and contribute to design reviews.
Bring a proactive, problem-solving, collaborative, and resilient approach to technical challenges.
