Job Description: The Reliability and Maintainability Engineer is a senior-level individual contributor responsible for driving investigation, root cause analysis, corrective action, and reliability improvement for V-BAT field failures, repeat defects, and complex technical issues requiring deeper engineering analysis.This role owns the technical investigation path for fielded V-BAT issues by using logs, returned hardware, test data, maintenance records, operational context, configuration data, and fleet trends to determine failure modes, root causes, contributing factors, and corrective actions. The Reliability and Maintainability Engineer partners closely with Fleet Support Engineering, Product Engineering, Quality, Manufacturing, Reliability Data Engineering, Supply Chain, and Operations to ensure field failures are understood, contained, corrected, and prevented from recurring.This role is accountable for translating field issues into structured technical investigations, verified corrective actions, reliability improvements, maintainability improvements, and clear product health insights that improve fleet readiness, customer support, and long-term system performance.

What you'll do:

Lead engineering investigations for V-BAT field failures, repeat defects, reliability issues, maintainability issues, and complex technical escalations.

Drive Root Cause and Corrective Action investigations for fielded V-BAT issues, including containment, root cause identification, corrective action planning, verification, and closure.

Reproduce and analyze field issues using logs, returned hardware, test data, maintenance records, operational context, configuration data, environmental conditions, and customer-reported symptoms.

Partner with Fleet Support Engineers, Product Engineering, Quality, Manufacturing, Reliability Data Engineering, Supply Chain, and Operations to investigate and resolve fielded system issues.

Determine whether issues are caused by design, manufacturing, supplier quality, configuration, software, operator use, environmental exposure, maintenance practices, documentation gaps, or system integration effects.

Lead and support returned material analysis, teardown reviews, bench testing, inspection planning, fault isolation, and failure replication activities.

Document failure modes, root cause, contributing factors, containment actions, corrective actions, verification plans, and recurrence-prevention measures.

Drive corrective actions through closure by ensuring actions have owners, due dates, verification methods, and measurable field-improvement outcomes.

Identify reliability and maintainability trends from field failures, repeat defects, maintenance data, test results, and product health indicators.

Recommend new tests, inspections, diagnostics, design changes, process changes, maintenance updates, or supplier quality actions to prevent recurrence.

Provide technical input to product health reviews, reliability readouts, sustainment reviews, fleet readiness assessments, and leadership updates.

Support development and improvement of R&M processes, including field failure review, FRACAS, RCCA, reliability growth tracking, maintainability feedback loops, and corrective action management.

Work with Product Engineering to ensure field-failure findings are translated into design improvements, retrofit plans, software updates, service actions, or configuration changes where appropriate.
