Job Description & How to Apply Below

We’re seeking a Senior Mechanical Designer with strong 3D modeling and drafting expertise, deep understanding of mechanical design principles, and experience translating complex engineering concepts into production‑ready documentation.

This role is ideal for a designer who thrives in a fast‑paced, highly technical environment — and who enjoys solving real engineering challenges through meticulous design execution.

Key Responsibilities
  • Design Execution:
    Develop high-quality 3D CAD models, assemblies, and detailed drawings for mechanical systems and components using Solid Works or Creo.
  • Design for Manufacturability:
    Collaborate with engineers and fabricators to ensure all designs meet DFM/DFA principles and production constraints.
  • Documentation:
    Generate engineering drawings with complete GD&T, tolerances, and BOMs in accordance with ASME standards.
  • System Integration:
    Support system‑level design by coordinating interfaces across structures, thermal systems, enclosures, and electrical integration points.
  • Configuration Control:
    Manage design data, revisions, and release processes using PDM/PLM tools.
  • Review & Validation:
    Participate in design reviews, tolerance stack‑ups, and fit‑check studies to validate form, fit, and function.
  • Mentorship:
    Provide guidance and technical support to junior designers and drafters on CAD practices, standards, and design methodologies.
  • Continuous Improvement:
    Contribute to the refinement of internal design standards, CAD libraries, and workflows to enhance efficiency and consistency.
Qualifications

Required:

  • Associate or Bachelor’s degree in Mechanical Design, Drafting, or related discipline.
  • 7+ years of professional experience as a mechanical designer in a hardware development environment.
  • Expert‑level proficiency in 3D CAD software (Solid Works, Creo, or NX).
  • Strong understanding of GD&T, dimensioning, tolerancing, and drawing standards (ASME Y14.5).
  • Experience designing machined, sheet metal, and fabricated components.
  • Ability to collaborate closely with engineers and manufacturers to resolve design challenges.
  • Excellent attention to detail and strong organizational skills.

Preferred:

  • Experience in aerospace, energy, or defense hardware environments.
  • Knowledge of materials, coatings, and high‑performance fabrication methods.
  • Proficiency with PDM/PLM systems (e.g., Windchill, Teamcenter, Solid Works PDM).
  • Hands‑on experience with prototype assembly and testing.
What We Offer
  • Competitive compensation and benefits package.
  • Opportunities for professional growth and advancement.
  • A collaborative, high‑performance engineering culture.
  • Access to cutting‑edge design tools and prototyping facilities.
  • The chance to make a tangible impact on next‑generation energy systems.
