## Description

Shield AI is seeking a Senior Propulsion Engineer to serve as the propulsion SME for the V-BAT Fleet Support team. In this role, you will be the customer-facing engineering lead for escalated propulsion issues across the fielded fleet. You will act as the bridge between Fleet Support and the core propulsion, vehicle, manufacturing, and quality engineering teams to diagnose issues, drive root cause, and improve fleet reliability.

This role is ideal for an engineer who combines strong propulsion fundamentals with practical field troubleshooting experience and a customer-first mindset.

Responsibilities: 	Serve as the propulsion SME for Fleet Support and the primary engineering point of contact for propulsion-related escalations. 	Diagnose and resolve engine performance issues, including hard starts, unstable operation, power loss, thermal excursions, endurance degradation, and intermittent behavior. 	Troubleshoot engine mechanical and hardware issues, including vibration, wear, leaks, mounting or interface issues, actuator concerns, and component failures. 	Investigate fuel and oil system issues, including pressure, flow, filtration, contamination, venting, priming, lubrication, and thermal-management problems. 	Analyse flight data, maintenance records, teardown findings, and field reports to identify failure modes and define corrective actions. 	Develop troubleshooting procedures, inspection criteria, repair guidance, and return-to-service recommendations for Fleet Support personnel and customers. 	Partner with propulsion, air vehicle, quality, manufacturing, and supplier teams to drive permanent corrective actions and reliability improvements. 	Capture recurring fleet issues and translate them into engineering recommendations, service actions, and long-term design improvements.
