Job description

Company Description

At Exum Instruments, we are transforming chemical analysis by developing powerful, intuitive, and accessible scientific instruments—such as our flagship Massbox®. We believe that advanced instrumentation shouldn't be confined to massive, specialized labs; it should be everywhere innovation happens. We thrive in a high-paced, collaborative environment where creative problem-solving and rapid execution drive our success.

Role Description

We are seeking a driven and talented Mechanical Engineer II to join our growing engineering team. The role is based on-site in Lakewood, CO in a full-time capacity. In this role, you will play a critical part in designing and optimizing ultra-high vacuum (UHV) components and complex electromechanical systems. We harness a blend of rapid prototyping and production techniques to take designs from concept to reality. You'll be responsible for design ideation, prototyping, validation testing, and production verification. If you have a passion for precision mechanics, a deep understanding of vacuum technology, and exceptional CAD skills, we want to hear from you.

Key Responsibilities

• UHV Design: Design, model, and optimize ultra-high vacuum (UHV) components, chambers, manifolds, optomechanical systems, and integrated electromechanical sub-systems.
• Rapid Prototyping & Production: Leverage rapid prototyping methods (3D printing, in-house machining) alongside traditional manufacturing techniques to quickly test, iterate, and finalize production-ready designs.
• Documentation & Detail: Create thorough fabrication drawings, BOMs (Bills of Materials), and assembly documentation while maintaining strict revision control.
• Cross-Functional Collaboration: Work closely with electrical engineers, software developers, and production teams to ensure seamless instrument integration and manufacturability (DFM/DFA).
• Testing & Validation: Develop and execute test plans for vacuum integrity, thermal performance, and mechanical reliability.

Qualifications

• Strong foundation in Mechanical Engineering with experience in optomechanical systems, UHV design practices, micro precision engineering, and using the metric system like a normal human being.
• Proficiency in Computer-Aided Design (CAD) tools for 3D modeling, assemblies, and detailed GD&T drawings. SolidWorks and PDM experience preferred.
• Experience with Product Development Lifecycle, including R&D, prototyping, testing, and iterative design improvement.
• Project Management skills to plan tasks, track progress, and coordinate with internal and external stakeholders.
• Bachelor’s degree or higher in Mechanical Engineering or a closely related field.
• Microsoft 365 proficiency including Word, OneNote, Excel, Outlook, and PowerPoint.
• Knowledge of materials, manufacturing processes, and tolerance analysis; experience in instrumentation or scientific equipment is a plus.
• Effective communication skills and the ability to collaborate in multidisciplinary teams.

What We Offer

• Competitive salary respective to Denver, CO ($85,000-$100,000) per year based on experience
• Unlimited flexible paid time off (PTO)
• A hands-on role with a high degree of ownership and impact on cutting-edge scientific technology
