We are seeking a Mechanical Engineer in our Broomfield, CO location. This role is responsible for designing, building, and validating complex mechanical and opto-mechanical systems from concept through production release, with a strong focus on creative problem-solving, reliability, scalability, and robustness. You will also be responsible for research and development, new product introduction, prototype builds, system characterization, integration, documentation, and transfer to production. You will work cross functionally with design, manufacturing, quality, and supply chain teams to deliver robust mechanical components and assemblies that support both prototype development and production hardware.
All applicants for placement in safety-sensitive positions will be required to submit to a pre-employment drug test.
Key Responsibilities:
- Design and develop mechanical components and assemblies from concept through production release, including prototype and production hardware.
- Create and maintain 3D CAD models and 2D drawings using industry standard CAD tools, applying GD&T and best drafting practices.
- Release and manage product data, drawings, and change orders in the PLM system in accordance with configuration management processes.
- Perform basic to intermediate mechanical analyses (e.g., structural, thermal, tolerance, and trade studies) to support design decisions.
- Collaborate with manufacturing, quality, and supply chain teams to ensure designs are manufacturable, reliable, and scalable.
- Develop and maintain engineering documentation such as specifications, test plans, assembly procedures, and work instructions.
- Participate in design reviews and contribute to technical risk identification and mitigation. Contribute to continuous improvement of engineering processes, tools, and standards.
YOU MUST HAVE:
- Minimum bachelor’s degree
- 4+ years of experience of mechanical engineering.
- Minimum 4+ years of mechanical design experience, including CAD based modeling, electro-mechanical design and packaging, and stress and thermal analysis.
