Senior Hardware Reliability Engineer

Anduril Industries is a defense technology company with a mission to transform U.S. and allied military capabilities with advanced technology. By bringing the expertise, technology, and business model of the 21st century’s most innovative companies to the defense industry, Anduril is changing how military systems are designed, built and sold. Anduril’s family of systems is powered by Lattice OS, an AI-powered operating system that turns thousands of data streams into a realtime, 3D command and control center. As the world enters an era of strategic competition, Anduril is committed to bringing cutting-edge autonomy, AI, computer vision, sensor fusion, and networking technology to the military in months, not years. ABOUT THE TEAM: 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. ABOUT THE JOB: We are seeking an experienced Reliability Engineer to join our team in Lexington, MA / Waltham, MA, driving reliability for our Imaging product line. This is a hands-on role focused on embedding reliability into early product architecture and detailed design - from early concept trade studies through design validation and transition to manufacturing. 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. Your responsibilities will include conducting reliability predictions and allocations during architecture trades, leading design FMEAs and fault tree analyses to identify and mitigate failure modes, developing and executing design verification test plans, performing stress-derating analysis and parts selection reviews, and assessing design changes for reliability impact throughout the development cycle. The right person for this role brings deep technical knowledge of hardware reliability and failure mechanisms, has practical experience on product development programs, and can engage credibly with design engineers and Anduril's subcontractors on technical details while maintaining focus on system-level reliability outcomes. This role demands someone who can embed early in design cycles, influence engineering decisions with data and analysis, and take ownership of reliability outcomes as designs mature from concept to launch readiness. WHAT YOU'll DO: Performing Failure Modes Effects and Criticality Analyses (FMECA) and Fault Detection/Fault Isolation (FDFI) analyses and collaborating cross-functionally to implement product improvements for reliability Performing predictive reliability analyses to forecast probability of field failures and MTTF/MTBF utilizing Anduril requirements, specifications and relevant industry standards (i.e. MIL-HDBK-217Plus). Developing Maintainability prediction models using MIL-HDBK-472 and support the development of Preventative Maintenance and Sparing Plans Developing and communicating RAM (Reliability, Availability, Maintainability) reports internally and to external parties Reviewing field failure data and performing Weibull analyses utilizing that data to determine gap to initial model in order to further fine tune and adjust it for further predictions Collaborate with HW teams and Failure Analysis (FA) labs to investigate the root causes of time-based failures and guide design iterati…
