Reliability Engineer

CACI International Inc; Danbury (CT); On-site; USD 94,000 - 198,000; Full time

Job summary

CACI International Inc seeks a Reliability Engineer to lead RAMS initiatives for spacecraft, launch vehicles, and ground support systems, ensuring mission assurance across life cycles.

You will perform FMEA/FMECA, FTA, RBD analyses; develop reliability predictions; support PDR/CDR/MRR reviews; collaborate with quality and parts teams to select flight hardware.

Qualifications

• U.S. citizen with ability to obtain and maintain a U.S. government security clearance.
• Bachelor's degree in Aerospace, Mechanical, Electrical, Systems Engineering, or related technical field.
• 4-7 years of relevant experience in reliability/mission assurance engineering, preferably spacecraft, launch vehicle, or satellite programs.
• Working knowledge of reliability tools and methodologies: FMEA/FMECA, FTA, RBD, Weibull analysis, worst-case/derating analysis.
• Familiarity with space-industry reliability and mission assurance standards.
• Understanding of space environmental effects on hardware and their impact on reliability.
• Experience with reliability/statistical software (e.g., Windchill Risk and Reliability, Minitab, MathCAD).
• Strong analytical and problem-solving skills; ability to work through ambiguous, high-consequence design trade-offs.
• Excellent written and verbal communication skills; experience presenting at technical design reviews.

Responsibilities

• Perform FMEA/FMECA, Fault Tree Analysis (FTA), and Reliability Block Diagrams (RBD) for spacecraft subsystems to identify single points of failure and mission-critical risks.
• Develop reliability predictions and lifetime assessments for components operating in extreme space environments using MIL-HDBK-217, NPRD/EPRD, or physics-of-failure models.
• Develop and track reliability metrics including MTBF, failure rates, redundancy margins, and mission success probability across design life.
• Support design reviews (PDR, CDR, MRR) by presenting reliability analyses, risk assessments, and open-item dispositions to internal and customer/program stakeholders
• Collaborate with quality, components, and parts/materials engineering to ensure compliance with applicable standards
• Assess supplier/vendor component reliability data, qualification status, and heritage for flight hardware procurement decisions.
• Contribute to lessons-learned databases and continuous improvement of reliability processes supporting Danbury program missions.
• Support radiation effects analysis (TID, SEE, displacement damage) in coordination with parts engineering to ensure component suitability for mission orbit/duration.

The Opportunity

We are seeking a skilled Reliability Engineer to support our Specialty Engineering team. In this role, you will drive reliability, availability, maintainability, and safety (RAMS) initiatives for spacecraft, launch vehicles, and ground support systems — ensuring our hardware and software meet mission assurance requirements for high-reliability, long-duration, and often unmaintainable space applications.

Responsibilities

• Perform FMEA/FMECA, Fault Tree Analysis (FTA), and Reliability Block Diagrams (RBD) for spacecraft subsystems to identify single points of failure and mission-critical risks.
• Develop reliability predictions and lifetime assessments for components operating in extreme space environments (radiation, vacuum, thermal cycling, vibration/launch loads) using tools such as MIL-HDBK-217, NPRD/EPRD, or physics-of-failure models.
• Develop and track reliability metrics including MTBF, failure rates, redundancy margins, and mission success probability across design life.
• Support design reviews (PDR, CDR, MRR) by presenting reliability analyses, risk assessments, and open-item dispositions to internal and customer/program stakeholders
• Collaborate with quality, components, and parts/materials engineering to ensure compliance with applicable standards
• Assess supplier/vendor component reliability data, qualification status, and heritage for flight hardware procurement decisions.
• Contribute to lessons-learned databases and continuous improvement of reliability processes supporting Danbury program missions.
• Support Electrical Engineering in worst-case analysis (WCA), derating analysis, and parts stress analysis per NASA/aerospace standards
• Support radiation effects analysis (TID, SEE, displacement damage) in coordination with parts engineering to ensure component suitability for mission orbit/duration.

Qualifications

Required:

• U.S. citizen with the ability to obtain and maintain a U.S. government security clearance
• Bachelor's degree in Aerospace, Mechanical, Electrical, Systems Engineering, or related technical field.
• 4-7 years of relevant experience in reliability/mission assurance engineering, preferably supporting spacecraft, launch vehicle, or satellite programs.
• Working knowledge of reliability tools and methodologies: FMEA/FMECA, FTA, RBD, Weibull analysis, worst-case/derating analysis.
• Familiarity with space-industry reliability and mission assurance standards
• Understanding of space environmental effects on hardware (radiation, thermal vacuum, launch vibration/shock) and their impact on reliability.
• Experience with reliability/statistical software (e.g., Windchill Risk and Reliability, Minitab, MathCAD).
• Strong analytical and problem-solving skills with the ability to work through ambiguous, high-consequence design trade-offs.
• Excellent written and verbal communication skills; experience presenting at technical design reviews.

Desired

• Master's degree in a relevant engineering discipline.
• Familiarity with radiation hardness assurance (RHA) processes and EEE parts selection for flight hardware.
• CRE (Certified Reliability Engineer) certification or equivalent.

This position is contingent on funding and may not be filled immediately. However, this position is representative of positions within CACI that are consistently available. Individuals who apply may also be considered for other positions at CACI.
