About Innoven Energy

Innoven Energy is at the forefront of laser-driven fusion energy. Our KrF excimer laser platform for Inertial Confinement Fusion (ICF) is engineered to deliver high-gain, clean energy with repeatability and scalability. Following the completion of a multi-year research and engineering campaign, the company is transitioning to a full system engineering and demonstration phase. We're assembling a world-class team of scientists and engineers to make fusion energy a commercial reality.

Position Overview

This position will work closely with our Optical Architect/Engineer and other multidisciplinary team members to develop robust, precise, and scalable mechanical solutions supporting advanced laser hardware and optical assemblies. The ideal candidate will bring deep experience in large-scale mechanical systems, structural analysis, and CAD-based product development.

Key Responsibilities

• Develop, model, and analyze mechanical and opto-mechanical assemblies using SolidWorks.
• Execute detailed stress, thermal, and dynamic analysis on large mechanical structures, including pressure vessels, pipe networks, and optical support systems.
• Design precision mechanisms and fixtures for alignment and mounting of large-scale optics.
• Interpret and apply structural and mechanical engineering principles in the context of ICF systems, vacuum chambers, and laser systems.
• Generate fabrication-ready 3D CAD models, detailed drawings, and bill of materials (BOMs).
• Support structural design validation through FEA (Finite Element Analysis) and other simulation tools.
• Collaborate cross-functionally with optical, electrical, and systems engineering teams to integrate mechanical designs into high-energy systems.
• Oversee prototyping, testing, and iteration of mechanical components and assemblies.
• Manage documentation of design intent, test results, and design modifications.
• Coordinate with vendors and fabricators for component sourcing and manufacturing.

Required Qualifications

• B.S., M.S., or Ph.D. in Mechanical Engineering, or related field.
• Minimum of 5 years of experience in mechanical design and engineering, preferably in high-tech or R&D environments.
• Advanced proficiency with SolidWorks, including part/assembly modeling, motion studies, and rendering.
• Experience with stress analysis and structural modeling of large-diameter pipes, vacuum vessels, and welded assemblies.
• Understanding of structural dynamics, materials science, and heat transfer fundamentals.
• Familiarity with opto-mechanical engineering principles, including alignment tolerances and vibration isolation.
• Strong knowledge of GD&T, ASME Y14.5 standards, and mechanical drawing interpretation.
• Ability to read and interpret complex engineering drawings, specifications, and technical documentation.
• Self-directed, able to work independently under guidance from senior leadership.
• Excellent communication and technical documentation skills.
• U.S. citizenship is required

Preferred Qualifications

• Licensed Professional Engineer (PE) or equivalent credential.
• Experience in the design of high-vacuum systems, pressure-rated vessels, or high-energy physics instrumentation.
• Proficiency with MATLAB or Python for engineering calculations, data analysis, or design automation.
• Familiarity with optical engineering, particularly handling and integration of large-aperture optics.
• Experience with fabrication processes, including machining, welding, and metal finishing.
• Exposure to fusion energy, laser systems, or large-scale R&D programs (e.g., at DOE national labs).
