Senior Build Reliability Engineer

Overview

The Build Reliability Engineer (Rocket Engines) ensures the integrity, reliability, and manufacturability of Ursa Major rocket engines throughout their lifecycle — from concept through hot-fire testing and production release.

You will partner with design, manufacturing, and test teams, developing and executing reliability and quality strategies that make engines robust, repeatable, and production-ready. This is a hands-on technical role, deeply embedded in production and test operations.

You'll drive process improvements, validate inspection and test methods, investigate failures, and lead data-driven problem-solving efforts that directly affect engine performance. While this position operates within an AS9100-compliant environment, it is not a compliance or auditing role — it's about building engines that work the first time, every time.

Key Responsibilities

• Partner with design, manufacturing, and test teams through development and production to create and execute quality and reliability plans for rocket engines and major subsystems — including identification of key characteristics, prototype validation, inspection planning, and lessons learned integration.
• Develop, implement, and validate Lean test and inspection processes for new and existing hardware to ensure criteria are objective, data-driven, and production-efficient.
• Monitor engine and process performance through production ramp-up using statistical and analytical tools to identify trends and drive proactive improvements.
• Conduct build quality reviews to verify design intent and highlight opportunities to reduce risk, improve manufacturability, and eliminate recurring issues.
• Investigate and resolve failures during manufacturing, test, and operation — identifying root causes, leading corrective actions, and improving process robustness.
• Contain and control nonconforming product, coordinating with inspectors, technicians, and engineers to ensure timely disposition, rework, and re-verification.
• Advance Lean and autonomous production systems by standardizing rework guides, reducing redundant inspections, and optimizing critical process controls.
• Mentor junior Quality Engineers, fostering technical rigor, ownership, and sound engineering judgment.
• Support AS9100 requirements and customer standards, maintaining disciplined documentation and contributing to ongoing system-level improvements.
• Drive a reliability-first culture — integrating quality and design thinking across engineering, manufacturing, and test.
