About the Job

Requirements

  • At least 6 years of mechanical design experience in automotive electronics, sensors, or ECUs; ADAS experience is strongly preferred.
  • Strong 3D CAD skills in at least one of Siemens NX, CATIA V5/3DEXPERIENCE, or PTC Creo, including surfacing for plastic parts.
  • Hands-on experience with GD&T and tolerance stack-up analysis using CETOL, 3DCS, or spreadsheets.
  • Solid knowledge of plastic part design, including draft, ribs, bosses, snap fits, weld lines, and shrinkage, as well as die-cast and sheet-metal design rules.
  • Working knowledge of FEA tools such as ANSYS, Abaqus, or HyperWorks for static, modal, and random-vibration analysis.
  • Experience with DFMEA, DFM/DFA, and design reviews.
  • Familiarity with automotive environmental standards such as ISO 16750, ISO 20653 IP codes, LV 124, or equivalent OEM standards.
  • Understanding of automotive product development processes, including APQP, PPAP, IATF 16949, and engineering change management.
  • Fluent communication with internal and external engineers.
  • Support project management.
  • Experience working with Japanese OEMs and Tier 1 suppliers in the automotive domain.
  • Good English communication skills for practical work, including meetings and email.
  • Native-level or business-level Japanese, with the ability to read, write, and speak.

Responsibilities

  • Design enclosures, covers, brackets, and mounts for ADAS sensors, including front and surround cameras, corner and front radars, LiDAR, ultrasonic sensors, and ADAS domain ECUs.
  • Develop windshield-camera brackets, radar-mounting brackets, and bumper/fascia integration features that keep sensors aligned within specified tolerances.
  • Design for radar radome transparency by considering material dielectric properties, wall thickness, and paint stack, and provide camera field-of-view clearance while controlling glare and stray light.
  • Create 3D models and fully detailed 2D drawings with GD&T in accordance with ASME Y14.5 and ISO 1101.
  • Perform worst-case and RSS tolerance stack-up analyses for sensor aim, connector mating, and PCB-to-housing fit.
  • Run or support FEA for structural, modal and random vibration, mechanical shock, and drop cases.
  • Define DV/PV mechanical test plans to ISO 16750, LV 124, or OEM specifications covering vibration, thermal shock, humidity, salt spray, and dust/water ingress, and drive root-cause investigation for failures.
  • Own mechanical DFMEA and support PFMEA and control plans.
  • Apply DFM/DFA to injection-moulded plastics, aluminium die-cast parts, sheet-metal parts, and machined parts.
  • Work with suppliers on tool design, mould-flow results, first-article inspection, and PPAP.
  • Support APQP milestones, design reviews, and engineering change management through SOP.
  • Coordinate with electronics teams on PCB outlines and connector placement, optics, RF, software teams, and OEM vehicle-integration engineers on packaging and interfaces.
  • Maintain BOMs and release data in PLM systems, including Teamcenter, Windchill, or ENOVIA, and keep design documentation current.

Desired Qualifications

  • Detailed understanding of automotive safety regulations, including Euro NCAP, ASEAN NCAP, IIHC, Global NCAP, and Japan NCAP.
  • Bachelor's degree or higher in Electrical/Electronic Engineering, Mechanical Engineering, Systems Engineering, Computer Science, or another field.
  • Direct experience designing camera, radar, or LiDAR housings, including radome design and sensor calibration/alignment fixtures.
  • Awareness of ISO 26262 functional safety and how mechanical failures affect the safety case.
  • Exposure to thermal simulation using FloTHERM or Icepak and to mould-flow analysis.
  • Experience with laser welding, ultrasonic welding, adhesive dispensing, and press-fit connectors.
  • Experience interacting with OEM customers and integrating sensors into vehicles at the bumper, windshield, grille, or roof.
  • Clear technical communication with OEMs, suppliers, and cross-functional teams.
  • Experience with structured problem-solving methods such as 8D, 5-Why, and Ishikawa.
  • Ownership of deliverables against program timelines.
  • Ability to mentor junior engineers at senior level.
