Senior Reliability Engineer

About the role

We are seeking a Senior Reliability Engineer (REL) to lead efforts in ensuring the long-term performance, durability, and robustness of critical hardware systems. This role is a key part of our Hardware Reliability team, with a focus on driving reliability strategy, testing, and validation across a broad range of electromechanical components, including sensors.

Responsibilities

• Lead reliability engineering efforts across hardware programs, ensuring components and systems meet demanding performance, environmental, and durability requirements.
• Apply Design for Reliability (DfR) principles throughout the product lifecycle, from concept through production, to proactively mitigate failure risks.
• Develop and execute comprehensive test strategies to uncover failure modes, validate off-the-shelf and custom hardware, and model expected field performance.
• Translate FMEA and reliability risk analyses into targeted test plans with clearly defined objectives, acceleration factors, and pass/fail criteria.
• Plan and run Design of Experiments (DOE) to isolate root causes and address key reliability concerns.
• Design and optimize test fixtures and setups to evaluate hardware under electrical, thermal, mechanical, and environmental stresses (shock, vibration, thermal cycling, etc.).
• Drive and support failure analysis investigations, collaborating closely with design, manufacturing, and component teams to identify root causes and implement corrective actions.
• Leverage data analytics tools (e.g., Python, JMP, MATLAB) to automate testing workflows, perform reliability modeling (e.g., Weibull, Monte Carlo), and extract actionable insights from test data.
• Champion continuous improvement in reliability processes and tools across hardware engineering teams.

Requirements

• Bachelor’s degree in Electrical Engineering, Mechanical Engineering, Materials Science, or a related field (Master’s preferred).
• 5+ years of hands-on reliability engineering experience, preferably in electromechanical systems or sensors.
• Proven track record in testing and validating hardware components for long-term field performance.
• Strong understanding of physics of failure and reliability engineering principles, particularly for electronic, optical, or mechanical systems.
• Experience with environmental and mechanical stress testing, including test design, execution, and result interpretation.
• Familiarity with reliability analysis tools and techniques: FMEA, Weibull analysis, SPC, HALT/HASS, and accelerated life testing.
• Proficiency in scripting or automation using tools such as Python, MATLAB, or LabVIEW.
• Experience working with reliability test equipment such as environmental chambers, vibration tables, thermocouples, strain gauges, and data acquisition systems.
• Strong communication and collaboration skills to work effectively with design, systems, manufacturing, and test teams.

Qualifications

• Hands-on experience in reliability engineering, specifically in electromechanical systems or sensors.
• Experience with reliability analysis tools and techniques, including FMEA, Weibull analysis, SPC, HALT/HASS, and accelerated life testing.
• Ability to design and execute comprehensive test strategies and failure analysis investigations.
• Experience with reliability engineering principles and practices, including DfR and DOE.
• Strong problem-solving and analytical skills.

Skills

• Reliability engineering principles and practices.
• Environmental and mechanical stress testing.
• Data analytics and automation tools (Python, MATLAB, LabVIEW).
• Test equipment and reliability engineering tools (environmental chambers, vibration tables, thermocouples, strain gauges, data acquisition systems).
• Collaboration and communication skills.

Benefits

• Immediate responsibility and accelerated career growth.
• Equitable compensation and continuous equity investment.
• Full access to health, vision, and dental insurance for you and your dependents.
• Supplemental life insurance.
• Flexible PTO.
• Commuter benefits to ease your daily commute.
• Paid parental leave.
