Reliability Engineer

The Reliability Engineer is responsible for conducting detailed Failure Modes, Effects, and Criticality Analyses (FMECA) on individual parts and sub‑assemblies and for developing comprehensive test plans that leverage accelerated aging methodologies to validate product reliability and lifecycle performance. The role collaborates closely with design engineers, material scientists, test laboratories, and program managers to ensure that reliability risks are identified early, quantified accurately, and mitigated through targeted testing and design improvements.

• Create and maintain component‑level FMECA worksheets following MIL STD 1629A (or equivalent) and internal reliability standards.
• Identify failure modes, associated causes, and effects on system performance.
• Assign criticality rankings and document mitigation strategies.
• Update FMECA results throughout the product development lifecycle and capture lessons learned.
• Define accelerated life‑test objectives and acceleration factors based on Arrhenius, Coffin‑Manson, or other appropriate models.
• Coordinate test execution with internal laboratories.

• Bachelor's degree in Electrical/Electronic Engineering, Mechanical Engineering, Aerospace Engineering, or a related technical field.
• 1‑3 years of hands‑on reliability engineering experience, with demonstrated expertise in component‑level FMECA and accelerated aging/thermal cycling tests.
• Strong root‑cause analysis, risk assessment, and data interpretation capabilities; comfortable working with large data sets and generating actionable insights.
• Proficiency with reliability analysis standards (such as MIL STD 1629A, IEC 60812, etc.).
• Strong knowledge of failure physics, degradation mechanisms, and material behavior under stress.
• Ability to develop and interpret test plans using ASTM, IEC, or MIL test methods.
• Ability to manage multiple concurrent analyses and test programs, meet deadlines, and maintain documentation control.
• Excellent oral and written communication skills, technical writing experience, and an ability to perform oral presentations in front of large groups.

• Familiarity with Model‑Based Engineering tools (e.g., Cameo).
• Experience using reliability software (e.g., Relia Soft, Weibull++, ANSYS Reliability) and statistical tools (Minitab, R, Python).
• Practical hands‑on experience with hardware test and troubleshooting.
• Analytical thinker with a demonstrated ability to solve complex problems requiring ingenuity and innovation.
• Ability to manage subcontractors in the reliability field of expertise.

• 401(k)
• Medical, dental, and vision coverage
• Sick time as applicable to state law
