Senior Reliability Engineer

Independent energy is here. Help us deploy it.
Energy should be free. Free from aging grids, fragile supply chains, and unnecessary extraction. At Moment Energy, we’re building a world where clean power is abundant, affordable, and uninterrupted for everyone.
The world doesn’t need another promise about energy;
it needs proof that a freer future is possible. Moment Energy is the pragmatic liberator of power, the only company certified to turn the largest untapped energy supply into independent energy.
Now is the moment. While the industry scraps millions of batteries with decades of life left, we put them to work by repurposing large-format batteries into advanced battery energy storage systems that deliver real-world impact.
We were told second-life batteries would never be safe enough or scalable enough. We didn’t argue, we engineered the solution. Today, Moment Energy delivers 5x the energy density and holds the certifications required to deploy energy independence at scale.
Now is the moment. Join us.The OpportunityWe are seeking a
Senior Reliability Engineer
to help ensure the long-term reliability, durability, and performance of Moment Energy's battery energy storage systems (BESS). In this role, you will develop reliability models, translate field and simulated operating conditions into mission profiles, and help predict product life and identify potential failure mechanisms. You will also support failure analysis investigations and prepare technical reliability reports that demonstrate product performance to our customers.
This is an opportunity to contribute to the development and improvement of our reliability engineering practices as we scale our second-life battery technology. You will work closely with engineering, testing, and product development teams to turn operating data into actionable engineering insights and help improve confidence in our products.
Responsibilities and Duties
Develop and apply reliability methodologies to assess product durability, expected service life, and performance across Moment Energy's battery energy storage systems.
Derive mission profiles using available field data, operating conditions, environmental exposure, and system usage patterns. Develop simulation-based approaches when sufficient field data is unavailable.
Contribute to damage models based on mission profiles, expected failure mechanisms, component characteristics, and anticipated operating conditions to evaluate degradation and estimate useful life.
Translate real-world mission profiles into appropriate accelerated test conditions that expose potential failure mechanisms and predict degradation without introducing unrealistic failure modes through excessive stress.
Support Design Failure Mode and Effects Analysis (DFMEA) and other reliability assessments to identify risks, prioritize failure modes, and recommend design improvements throughout product development.
Help guide technical discussions and investigations into product and component failures, particularly when the root cause is not immediately apparent. Recommend systematic, non‑destructive investigative methods before progressing to more intrusive testing or destructive analysis.
Analyze field performance, test results, and observed failure trends to help identify root causes, contributing factors, and opportunities to improve product reliability.
Prepare Customer Reliability Reports: Prepare technical documentation and reliability reports that communicate product performance, expected service life, testing results, assumptions, and supporting evidence to customers.
Work closely with electrical, mechanical, battery, systems, and test engineering teams to incorporate reliability considerations into design decisions, validation plans, and product improvements.
Help develop and improve reliability methods, analysis tools, documentation, and processes that can scale with Moment Energy's expanding product portfolio and manufacturing operations.
Use field feedback, test results, and failure investigations to recommend design changes and help prevent recurring issues across our products.
