Flexible Thermodynamics Engineer information

What is the difference between Flexible Thermodynamics Engineer vs Mechanical Engineer?

AspectFlexible Thermodynamics EngineerMechanical Engineer
Required CredentialsBachelor's or Master's in Mechanical, Thermodynamics, or related fields; certifications in thermodynamics or HVACBachelor's or Master's in Mechanical Engineering; licensure may be preferred
Work EnvironmentResearch labs, energy companies, HVAC firms, industrial settingsManufacturing, design firms, construction sites, R&D departments
Industry UsageEnergy, HVAC, renewable energy, industrial processesManufacturing, automotive, aerospace, product design

The Flexible Thermodynamics Engineer specializes in thermodynamic systems, energy efficiency, and flexible solutions within energy and HVAC sectors. In contrast, Mechanical Engineers have a broader scope, working across various mechanical systems and industries. While both roles require similar educational backgrounds, the Flexible Thermodynamics Engineer focuses more on energy-specific applications, making it a more specialized position within the mechanical field.

How much does a flexible thermodynamics engineer make?

A flexible thermodynamics engineer typically earns between $70,000 and $120,000 annually, depending on experience, location, and industry. Senior roles or those with specialized skills in simulation tools or certifications may offer higher salaries.

Job description

Mechanical Engineer

This role is fully onsite in Bloomfield, CT, five days per week, and the company will be relocating to Suffield, CT later in 2026.

About LiquidPiston

LiquidPiston, Inc. is developing the next generation of compact, high‑efficiency rotary engines based on its patented thermodynamic cycle. Our engines are being designed to transform power generation and propulsion across aerospace, defense, and commercial industries. We offer a fast‑paced, hands‑on R&D environment where mechanical engineers have a direct impact on shaping breakthrough technologies.

Position Overview

We are seeking a hands‑on, innovative Mechanical Engineer to join our dynamic team. In this role, you will contribute to all phases of engine development—from concept and design through testing and iteration—as we advance LiquidPiston’s rotary diesel engines toward production. This is a high‑impact, cross‑functional role requiring strong mechanical design skills, analytical thinking, and a passion for solving complex technical challenges.

Responsibilities
  • Design, analyze, and develop engine components, subsystems, and custom test rigs
  • Use SolidWorks for 3D CAD modeling and drafting of engine parts and assemblies
  • Conduct engineering analysis using a combination of hand calculations, Matlab, custom code, and commercial simulation tools (e.g., GT‑Suite)
  • Support prototype fabrication by working with in‑house machinists and external vendors
  • Participate in the operation and testing of rotary engines on dynamometers and data acquisition systems
  • Assemble and disassemble prototype engines; perform part inspections and document build details
  • Troubleshoot and debug mechanical systems through hands‑on work and root‑cause analysis
  • Collaborate with cross‑functional teams, technicians, and contractors to execute test and design projects
  • Present design proposals and test data clearly through reports, presentations, and team meetings
  • Help enforce engineering best practices and company policies (file organization, documentation, project management tools)
  • Stay current with advancements in rotary engines, diesel combustion, thermodynamics, and related technologies
Qualifications
  • Bachelor’s degree in Mechanical Engineering or a closely related field
  • Proficiency in CAD design (SolidWorks preferred)
  • Familiarity with Matlab and mechanical system modeling/analysis
  • Solid understanding of mechanical fundamentals: thermodynamics, kinematics, stress analysis
  • Hands‑on experience with mechanical systems—building, testing, or prototyping
  • Strong problem‑solving skills, self‑direction, and attention to detail
  • Excellent communication skills and ability to work in a collaborative team environment
Preferred Qualifications
  • Experience with internal combustion engines, especially rotary or diesel platforms
  • Familiarity with GT‑Suite or other engine simulation tools
  • Exposure to DAQ systems and test instrumentation
  • Experience managing prototype builds or working closely with machinists
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 stepping stone toward breakthrough innovation.
