Job Description Job Description Metal Additive Manufacturing
Designer/Modeler Location: Onsite in Bloomfield, CT About
LiquidPiston: LiquidPiston, Inc. is reinventing the internal
combustion engine. Our patented thermodynamic cycle and compact
rotary engine architecture are designed to deliver significantly
higher efficiency and power density than traditional engines. We’re
applying cutting-edge engineering—including additive manufacturing
and advanced optimization tools—to shape the future of propulsion
and portable power. Position Overview: We are seeking a talented
Engineer with a strong background in Additive Manufacturing and
Topology Optimization to join our R&D team. In this role,
you’ll be responsible for transforming next-generation rotary
engine designs through advanced computational design methods and
manufacturing technologies. You’ll work at the intersection of
simulation, design, and manufacturing to push performance and
efficiency beyond traditional boundaries. This is a hands-on,
high-impact position with opportunities to invent, iterate, and
deliver real-world solutions in a fast-paced development
environment. Key Responsibilities: Apply topology optimization and
additive manufacturing (AM) methods to design lightweight,
high-performance engine components Use nTop (preferred) or similar
software to optimize structural, thermal, and fluid-related
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 Required Qualifications:
BS or higher in Mechanical Engineering or related field 3 years of
professional experience in product design, simulation, and/or
manufacturing Expertise in additive manufacturing methods (e.g.,
DMLS, SLS, Binder Jetting, etc.) 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 Proven ability to work independently and solve
complex, cross-disciplinary problems Preferred Skills: Experience
with internal combustion engines, compressors, or advanced
thermodynamic systems Knowledge of GT-Suite, MATLAB, Python, or
other engineering simulation/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
Benefits: 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 Our Culture 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. Equal
