• Ability to Coach/ Mentor Team members in different Features

Key Responsibilities

1. Driving Position: Occupant packaging studies

• Define and develop driver workspace with focus on seat position, reach, posture, and accommodation

• Establish ergonomic targets using SAE recommended practices:

• J1100 (vehicle dimensions)

• J826 (H-point, manikin positioning)

• J941 (eyellipse and vision reference)

• J1516 / J1517 (accommodation tools and seat track)

• J198 (wiper zones reference in relation to vision)

• J4002, J4004 (extended accommodation/packaging guidelines)

• Perform accommodation analysis to ensure coverage across global anthropometric ranges

• Drive seat track, steering, pedal, and control reach alignment

2. Seat Ergonomics

• Define and evaluate:

• Seat cushion parameters (length, angle, stiffness, contour)

• Backrest parameters (height, angle, lumbar support)

• Headrest position and adjustability

• Seat adjustment ranges and usability

• Seat control button accessibility and placement

• Work closely with seat suppliers and internal teams to balance comfort, adjustability, and packaging constraints

3. Visibility

• Lead visibility development for compliance and performance:

• Direct visibility (forward, sidewards, downward)

• Indirect visibility (mirror systems)
