Powertrain Engineer

Pentangle Tech Services | P5 Group; Mount Vernon (WA); On-site; USD 90,000 - 130,000; Full time

Job summary

PENTANGLE TECH SERVICES | P5 GROUP seeks an onsite engineer to calibrate the engine and adjust the powertrain to improve drivability as a complete system. You will work with offsite test teams, integrate with onsite teams, and extend their capabilities to ensure alignment and timely execution.

Key duties include tuning acceleration and transients, low speed maneuvering, cold start fuel blends, cruise control, altitude performance, and CAN communication with the system and diagnostics suppliers.

Qualifications

• Experience calibrating engines and tuning drivetrain components.
• Familiarity with CAN communication and vehicle diagnostics.

Responsibilities

• Acceleration/transient response – gear shifts, transitions in/out of coasting and engine braking
• Low speed maneuverability – light pedal vehicle behavior, with/without load and grades
• Cold start – Fuel blends and altitude
• Cruise control
• Altitude performance – drivability, low speed, accel, derate strategy/reporting for the transmission
• Launch (idle governor) tuning for rear axle ratio range and transmission variants with PTC and transmission supplier jointly
• Extended idle performance (desorb and soot)
• PTO gain tuning for customer applications
• Torque limiting with brake application and powertrain component limits (max torque per gear, axle shaft, etc.)
• System integration including CAN communication and subsystem diagnostic communication

Job description
