Senior Reliability Engineer

Compensation: 120000 USD – 160000 USD / Year

***We are unable to work with 3rd-party or corp-to-corp candidates for this position***

Overview:

Our client will be hiring a Senior Reliability Engineer to join their growing team. As a Reliability Engineer focused on our client's Base product, you will have primary responsibility for the reliability assessment, validation, and design guidance of core electrochemical components, including iron flow battery stacks, electrochemical rebalancing cells, and fluid interfaces. You will own the reliability lifecycle—from concept and design through development testing and analysis, manufacturing, and field operation—ensuring exceptional performance at every stage.

How does this role add value immediately?
Iterate on the design, look at it from a materials standpoint, understand lifetime expectations, core component designs, failure analysis, data investigations. Set up processes.
 

In this role, you will investigate failures using physics-of-failure methods and physical testing to accurately predict component and system robustness. You will then translate these insights into design and architecture improvements that prevent recurrence and continuously enhance product reliability, as well as creating system level reliability estimates. You will act as a reliability advisor to system and hardware design teams, helping assess the suitability of off-the-shelf components for unique operating environment and long service-life requirements.

This position is 100% onsite in Wilsonville, Oregon.

Responsibilities:

Core Component Reliability

• Own reliability engineering of our iron flow battery stacks and rebalancing cells.
• Identify dominant degradation and failure mechanisms (electrochemical, chemical, mechanical, thermal, and environmental).
• Develop physics-of-failure models to guide accelerated life testing, operating limits, and design tradeoffs.
• Define reliability requirements and targets for core components based on field usage conditions, duty cycles, and costing models.
• Design and execute validation plans to determine expected operating lifetimes at different specification ranges.
• Lead teardown and failure analysis of lab-tested and field-returned components.
• Partner with relevant engineering functions to translate failure analysis findings into design changes, updated requirements, and validation improvements.

System-Level Reliability

• Support system-level reliability analyses, including fault trees, reliability block diagrams, and DFMEA.
• Help integrate component-level reliability data into system reliability models and predictions.
• Analyze field data from deployed systems to identify trends, emerging risks, and opportunities for design improvement.
• Serve as a reliability advisor to design teams evaluating off-the-shelf (OTS) components, helping assess whether commercially available parts are fit for long-duration, grid-scale energy storage applications.
• Review OTS component data sheets, qualification reports, and life-test data to evaluate assumptions, margins, and applicability to operating conditions.
• Translate specific duty cycles (electrical, thermal, mechanical, environmental, and chemical exposure) into clear reliability risks, gaps, and recommended validation or derating strategies.
• Provide guidance on when additional testing, screening, or supplier engagement is required before deployment.

Supplier & Cross-Functional Engagement

• Define and communicate reliability requirements for critical suppliers supporting battery and electrochemical components.
• Review and challenge supplier life-test data, assumptions, and acceleration models.
• Support supplier corrective actions related to reliability issues.
• Maintain and grow internal reliability guidelines, best practices, and lessons learned.

Qualifications:

• Bachelor's degree in Materials, Mechanical, Electrical Engineering, or a related field.
• 5 years' experience in reliability engineering, component development, or failure analysis
• Strong understanding of accelerated testing methods, governing equations, and physics-of-failure for a range of failure mechanisms.
• Experience with failure analysis techniques (e.g., optical microscopy, SEM, C-SAM, X-ray, cross-sectioning, EDX, etc.).

Preferred:

• Experience with batteries, flow batteries, fuel cells, electrochemical systems, or fluid-based energy systems.
• Proficiency with reliability engineering analysis tools such as the ReliaSoft platform.
• Solid foundation in applied statistics and reliability statistics (e.g., Weibull analysis, Maximum Likelihood Estimation, Bayesian methods, Monte Carlo simulation).
• Working knowledge of programming, preferably in Python.
• Familiarity with corrosive environments, polymers, or battery materials in general.
• Experience analyzing field reliability data for determining or predicting failure causes.
• Comfort working across disciplines in a fast-moving hardware development environment.
• Knowledge of reliability, warranty analysis, and reliability prediction methodologies.
• Familiarity with design-for-reliability methods, including integrating ECAD/MCAD/CAE data into 3D finite element models.
