Site Reliability Engineer

An aerospace and defense client is seeking a dedicated and proactive Site Reliability Engineer. 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., Minimum of 5 years experience as a Reliability Engineer, Design/Development Engineer, or Test Engineer
