Sigma Software · Foster City, CA · 3 wk ago
EngineeringFull-time

Required Qualifications

  • Bachelor’s degree in mechanical engineering, Manufacturing Engineering, or a related field
  • 7-8 years of experience in dimensional engineering, tolerance analysis, or geometric integration within automotive or other high-volume manufacturing environments
  • Strong working knowledge of GD&T (ASME Y14.5) with demonstrated application on production-intent designs
  • Hands-on experience with 1D/3D tolerance analysis tools, such as 3DCS
  • Proven experience supporting programs from concept through production launch, including detailed design, DV, PV, and SOP
  • Ability to interpret CAD models, engineering drawings, and build strategies to define robust dimensional requirements
  • Demonstrated experience working cross-functionally with Design Engineering, Manufacturing Engineering, Quality, and Suppliers
  • Strong analytical and problem-solving skills, including dimensional root cause analysis and corrective action development
  • Ability to clearly communicate technical requirements, risks, and trade-offs to diverse stakeholders
  • Solid understanding of manufacturing process capability and material-driven tolerances across common automotive components, including:
    • Stampings (steel and aluminum): spring back, forming variation, trim tolerance, and hemming effect
    • Castings (HPDC, LPDC, sand): draft, wall-thickness variation, shrink, machining stock, and post-machining datum
    • Injection-molded plastics: material shrink, warpage, fiber orientation, tooling condition, and environmental influences
    • Extrusions: profile variation, twist, bow, and cut-length tolerances
  • Ability to translate material behavior and process capability into realistic GD&T schemes and tolerance assumptions during design
  • Experience assessing supplier manufacturing feasibility and tolerance capability during sourcing and design reviews

Preferred Qualifications

  • Experience in an automotive OEM or Tier-1 supplier environment
  • Experience owning or contributing to DVA / DVP / black-box tolerance models, including compliant (flexible) part modeling to represent real-world assembly behavior
  • Hands-on experience modeling part compliance, locator strategies, and assembly sequence effects using 3D tolerance analysis tools (3DCS)
  • Ability to apply compliant modeling techniques to assess gap/flush, fit, and functional performance of flexible components such as stampings, plastic trims, seals, and closures
  • Knowledge of fixture strategy, locating schemes, and build sequence development
  • Experience supporting closures, BIW, interior, or exterior systems
  • Familiarity with craftsmanship targets, including flush, gap, and visual quality requirements
  • Experience supporting low-volume programs or new product launch environments

Benefits

  • Health Care Plan (Medical, Dental & Vision)
  • Life Insurance (Basic, Voluntary & AD&D)
  • Paid Time Off (Vacation, Sick & Public Holidays)
  • Training & Development
  • Retirement Plan (401k, IRA)
  • Free breakfast and lunch
