We are in the early stages of development and building our founding team. This is your chance to get in on the ground floor of something big! If you’re ready to work at a fun, fast-paced, groundbreaking organization that is positioned to revolutionize geothermal energy, apply today!

We’re seeking an innovative and versatile Mechanical Design Engineer to create new turbo-machinery. Collaborating with engineers across the company, this Mechanical Design Engineer will help design our next generation of power-generating turbine assembly, taking ownership from cradle to grave and driving the project through completion. This role will focus on mechanical design from piece parts to system integration, with both an attention to detail and a broad understanding of the product.

The role will involve working closely with Supply Chain, Manufacturing, Thermodynamics, Turbo-machinery, Field Ops, and other teams. This role will often be a central point of contact between teams. Candidates must be willing to be flexible in their work and help build the Company.

Experience specifically with turbo-machinery is not a requirement, but is a significant strength.

• Find new design solutions by integrating your own innovations with requirements and opportunities found by other subject-area experts (such as turbo machinery, fluid systems, electrical systems, and thermodynamic modeling).
• Create detailed CAD models and draft drawings per ASME Y14.5 to document and communicate your designs; collaborate with other engineers on checking and reviewing models & drawings.
• Perform structural analyses to validate your design; collaborate with other engineers on checking and reviewing structural analyses.
• Drive your project to delivery by supporting the fabrication, assembly, and testing of the hardware you’ve designed. Review production issues and proactively hunt for solutions.
• Support Field Ops teams with technical expertise and advice after product delivery. Accept feedback from Field Ops for design improvements.
• Developing innovative design concepts for new machines or fluid systems. You''ve created CAD models of parts that were actually produced and assembled into a machine.

• Bachelor's degree in mechanical engineering or related field, or equivalent experience.
• 4+ years of proven experience in a mechanical design role, with a strong portfolio of projects involving complex machinery. Experience specifically with turbo-machinery is not a requirement.
• A solid understanding of core mechanical engineering principles, including statics, dynamics, fluid mechanics, thermodynamics, and material science. Must be able to apply this understanding to first principles system sizing and modeling.
• Familiarity with designing for metal CNC machining.
• Familiarity with designing for casting, forging, additive, precision grinding, gear / spline hobbing and / or similar
• Familiarity with high-performance polymers for bushings / seals
• Proficiency in applying Geometric Dimensioning and Tolerancing (ASME Y14.5)
• Experience with a modern CAD package and a willingness to immediately self-teach proficiency in Siemens NX.
• Excellent analytical and problem-solving skills
• Highly self-motivated;
  Good communication and team-working skills

• Experience with assemblies and secondary systems common to engines and generators, like piping, fittings, valves, pumps, sensors, and actuators.
• Building and managing assemblies in CAD while ensuring proper fit and function of all individual piece parts. You can set up an assembly in CAD that is both digitally robust and easy to assemble in the real world.
• In-depth knowledge of the design and operation of specific types of turbo machinery (e.g., gas turbines, steam turbines, centrifugal…
