Reliability Engineer Jobs in Irvine, CA (NOW HIRING)

The Reliability Engineering team partners across Anduril's engineering, manufacturing, and operations organizations to ensure our autonomous systems survive real-world conditions and deliver consistent performance for our customers. Our mandate spans the complete product lifecycle - from early concept design through production scale-up and fielded operations. We use data, statistical methods, and engineering analysis to forecast how our systems will perform over time and influence design decisions, including part selection, redundancy strategies, and maintenance approaches. We establish tailored reliability frameworks by program and partner with Quality to drive design robustness, failure prevention, and rapid response to issues in the field.

Anduril's Reliability & System Safety Engineering organization is hiring Reliability Engineers across our product portfolio. Domains may include Air Dominance & Strike, Counter-UAS, Maritime, Ground Systems, Space, and Mission Autonomy. These are highly collaborative, hands-on roles spanning the entire product lifecycle - from early concept trade studies and detailed design through manufacturing scale-up, production, and sustained field performance. You'll be the reliability champion throughout the design and development process, working closely with mechanical, electrical, and software engineering teams to ensure designs are robust. You'll also partner with manufacturing, quality, test operations, and field service teams to transition these products from engineering prototypes to production-ready systems. Your scope will span performing predictive reliability analysis and FMEAs, developing and executing qualification and production test plans, leading root-cause failure investigations from both the factory floor and the field, and closing the loop to drive continuous design and process improvements. We are looking for candidates who bring deep technical knowledge of hardware reliability and failure mechanisms, practical experience in both design and production environments, and the ability to drive cross-functional alignment without direct authority. These roles demand independent, data-driven engineers who can build reliability infrastructure from the ground up and take ownership of product performance from concept to deployment.

• Support and review system block diagrams, interface control documents, and schematics for compliance, redundancy, and accuracy against requirements and concept of operations.
• Lead Failure Modes & Effects Analysis (FMEA) and Fault Tree Analysis (FTA) efforts, collaborating with cross-functional engineering teams to implement design improvements.
• Perform predictive reliability analysis to calculate probability of loss of control, loss of asset, and MTTF/MTBF utilizing Anduril requirements, specifications, and relevant industry standards (i.e. MIL-HDBK-217Plus).
• Develop and execute comprehensive Qualification and Validation Test plans (including environmental, life/limit, and accelerated testing) to ensure appropriate requirements coverage and de-risking for production readiness; partner with Test Engineering to fixture and instrument test campaigns.
• Work with Quality and Manufacturing Engineering to develop, refine, and validate assembly, integration, and testing processes (including inspection/acceptance test gates) to optimize build reliability and reduce time-to-deploy.
• Develop Maintainability prediction models using MIL-HDBK-472, and support the development of Preventative Maintenance & Sparing plans.
• Perform Weibull analysis utilizing data from qualification campaigns, production testing, and fielded assets to predict failures and identify trends.
• Lead failure investigations on anomalies originating from design validation, production testing, and field returns; drive root cause analysis and corrective/preventative actions (CAPA) to closure.
• Support Development Milestone Reviews through the identification of appropriate entry and exit criteria, guiding the transition of designs from engineering development to high-rate production.
• Develop and implement standardized reliability processes, tools, and infrastructure to streamline and accelerate our design, manufacturing, and deployment operations.

• Minimum of 5 years experience as a Reliability Engineer, Design/Development Engineer, or Test Engineer
• B.S. Degree in Mechanical Engineering, Aerospace Engineering, Systems Engineering, or equivalent technical discipline
• Experience with safety-critical hardware & software systems in the defense or aerospace industry
• Experience or familiarity with MIL-STD-810, MIL-HDBK-217, MIL-STD-461, MIL-STD-516C, and MIL-STD-1629
• Experience setting up a Reliability Engineering framework for a product or program, including support of production testing, field testing, data acquisition, and data analysis
• Expertise in reliability analysis techniques, including FMEA/FMECA, predictive modeling, Weibull analysis, and Fault Tree Analysis
• Experience with generating qualification testing requirements and executing tests to proactively characterize product behavior and performance
• Failure investigation/analysis experience with proven track record of solving problems and preventing reoccurrence
• Design Review Experience (PDR, CDR, MRR) and confidence in presentation skills across all levels of leadership
• Eligibility to obtain/maintain a U.S. Secret clearance, as required

• M.S. Degree in Mechanical Engineering, Aerospace Engineering, Systems Engineering, or equivalent technical discipline
• Experience with MIL-HDBK-217Plus, MIL-HDBK-472, MIL-STD-1916
• Experience with Manufacturing Readiness Level (MRL) Assessments, Manufacturing Review Board (MRB), Quality Inspection, Tooling, or Calibration
• Experience with risk management, change control/change management reviews, and software/firmware HITL/SITL
• Experience with HALT (Highly Accelerated Life Testing), HASS (Highly Accelerated Stress Screening), Environmental Testing, and/or Mechanical Testing
• Technical writing experience developing requirements, standards, specifications, user guides, and policies
