At Zone 5 Technologies, we're redefining what's possible in precision weapons and unmanned aircraft systems (UAS). Our team of engineers and innovators are developing cutting-edge autonomous solutions to deliver affordable and scalable precision weapons, interceptors, and UAS.

We're building the next generation of munitions and unmanned systems for the United States and its allies. If you're driven by hard problems, energized by rapid innovation, and ready to make an impact on defense technology, you belong here.

We are seeking a Senior Systems Reliability Engineer to lead Reliability & Maintainability (R&M) activities across the product lifecycle. This role focuses on R&M architecture, data-driven analysis, comprehensive documentation, and test planning for reliability verification. You will engage directly with customer counterparts on R&M reviews and milestone events, including Reliability Scoring Conferences, Corrective Action Boards, and Milestone B/C Design Reviews.

Key Responsibilities:

Reliability & Maintainability Architecture

Develop and maintain the R&M Program Plan and reliability architecture documentation, including the RAM-C (Reliability, Availability, Maintainability-Cost) Rationale Report
Lead Failure Modes, Effects, and Criticality Analysis (FMEA/FMECA), Fault Tree Analysis (FTA), and Reliability Block Diagram (RBD) development across system architecture
Develop R&M allocations and apportion reliability and maintainability requirements to lower-level items; support R&M requirements analysis and trade studies
Draft Reliability Predictions (per MIL-HDBK-217 and related methods) and Maintainability Analyses; maintain traceability between R&M requirements, predictions, and demonstrated performance
Lead Reliability-Centered Maintenance (RCM) and Level of Repair Analysis (LORA); support Testability and Built-In Test (BIT) analysis

Data, Documentation & Test Planning

Establish and own the Failure Reporting, Analysis, and Corrective Action System (FRACAS); maintain closed-loop failure data collection and trending from design through test, production, and sustainment
Develop Failure Definitions and Scoring Criteria (FDSC) and reliability test plans tied to program milestones
Lead reliability growth planning and execution of reliability growth and demonstration testing, including Environmental Stress Screening (ESS) and HALT/HASS where applicable
Support Qualification Test Plan development, all-up-round testing, and flight and live-fire test reliability assessments
Develop technical documentation including R&M standards, specifications, procedures, and user guides
Review ground test, flight test, and live-fire test data to confirm R&M requirements compliance

Customer Engagement & Reviews

Serve as primary point of contact with customers on R&M matters
Present R&M analyses, RAM-C Rationale Report updates, and risk posture at Milestone Reviews (A/B/C) and design reviews (PDR, CDR, TRR, PRR)
Lead Reliability Scoring Conferences and Corrective Action Boards (CAB) with customer participation
Coordinate responses to customer R&M data item deliverables and support In-Service Reviews

Risk Management & Process Improvement

Lead Root Cause and Corrective Action (RCCA) investigations for failures identified through FRACAS
Host corrective action reviews and ensure lessons learned are implemented across the program
Coordinate R&M risk mitigation with Manufacturing Engineering, Logistics, Quality, and System Safety, including DMSMS/obsolescence and shelf-life and aging surveillance considerations
Apply digital engineering and AI-enabled tools (predictive maintenance, digital twins, automated FRACAS analytics) to R&M processes
Ensure compliance with MIL-STD-785, MIL-HDBK-217, GEIA-STD-0009, and other applicable R&M standards

Basic Qualifications:

7+ years as a Reliability Engineer, R&M Engineer, or equivalent reliability-critical engineering role
Bachelor's degree in Mechanical, Aerospace, Systems, or Electrical Engineering, or Physics
Expertise with MIL-STD-785, MIL-HDBK-217, and related R&M standards
