Mechanical Engineer II

About the role

Quaise Energy is a technology innovator and project developer focused on harnessing superhot geothermal energy through millimeter wave drilling. This role is for a Mechanical Engineer II who will lead component-level design and development for lab-scale and field-ready mmW drilling systems.

Responsibilities

• Lead component-level mechanical design from requirements definition through detailed drawings, release, manufacturing, and testing.
• Perform tolerance stack-up analysis and apply GD&T principles to ensure fit, function, and manufacturability.
• Support the design and development of testing and drilling systems for the Quaise mmW Drilling System.
• Perform engineering analysis including structural analysis, thermal analysis, and fluid system evaluation to support design validation and optimization.
• Utilize FEA tools to evaluate components and assemblies against expected operating conditions and loads.
• Apply ASME standards and engineering best practices in component selection and mechanical system design.
• Assist with CFD evaluations and flow analysis to support fluid and thermal system development.
• Design, execute, and document experiments and testing activities, including Design of Experiments methodologies where appropriate.
• Identify, specify, and integrate sensors, actuators, and instrumentation used in experimental and operational systems.
• Develop and integrate hardware for laboratory experiments, test fixtures, and field-ready drilling systems.
• Select materials and components based on thermal, structural, fatigue, and operational requirements.
• Maintain organized engineering documentation including drawings, calculations, analyses, BOMs, and test records.
• Collaborate with vendors and manufacturers to source custom and commercially available components.
• Troubleshoot mechanical and experimental systems and support recovery efforts during testing and field operations.
• Participate in technical reviews and cross-functional engineering discussions.

Requirements

• Proficiency with CAD software; Creo experience preferred.
• Strong understanding of GD&T, tolerance analysis, and mechanical design principles.
• Experience with structural analysis tools such as ANSYS Mechanical or similar FEA platforms.
• Working knowledge of fluid systems, thermal systems, and mechanical testing methodologies.
• Familiarity with ASME standards related to tubing, fittings, flanges, and pressure-containing systems.
• Ability to independently execute engineering tasks and manage multiple technical priorities simultaneously.
• Strong analytical and problem-solving skills in experimental or fast-paced development environments.
• Strong organizational skills and attention to detail, including maintaining review-ready engineering documentation.
• Comfortable operating within a startup or high-growth environment with evolving priorities.
• Excellent verbal and written communication skills.
• Proficient with Microsoft Office Suite and familiarity with project planning tools.
• Ability to interact effectively with coworkers, vendors, contractors, and cross-functional teams in both office and field environments.

Qualifications

• Bachelor’s degree or higher in Mechanical Engineering or related engineering discipline required (Mechanical, Aerospace, Mechatronics, Robotics, or similar).
• 2–5 years of related engineering experience in a design-focused or product development environment.
• Demonstrated ability to independently execute component-level design, analysis, testing, and troubleshooting activities.
• Experience working in laboratory, R&D, manufacturing, energy, aerospace, industrial, or other highly technical engineering environments preferred.

Physical requirements

• This role requires prolonged periods sitting at a desk and working on a computer.
• The employee is regularly required to stand, sit, walk, stoop, kneel, crouch, or crawl, as well as use hands to feel, reach, grasp, handle, or operate objects, tools, and/or controls.
• The employee must be able to lift, push, pull, transfer, or move items up to 50 pounds at times for departmental needs.
• Able to move between worksites or travel to various job sites and locations to complete tasks.
• The vision requirement includes reviewing written and electronic materials in digital and physical format.
• Able to work safely around high voltage and high-power systems while adhering to established safety protocols and procedures.
• The employee must be able to adjust to changing work hours and locations as needed in support of operational and testing activities.
