Company Overview
Mainspring Energy is revolutionizing power generation with the world’s most flexible and adaptable onsite power generator, the Mainspring Linear Generator. Commercial, industrial, and utility leaders are choosing Mainspring over traditional options like engines, turbines, and fuel cells to quickly and reliably deliver local power for EV charging, commercial facilities, data centers, and grid-scale operations. The Mainspring Linear Generator is fuel flexible, ramps up and down to meet demand, and utilizes a flameless technology with near-zero NOx emissions.
Backed by top-tier investors such as Khosla Ventures, Bill Gates, American Electric Power, and Lightrock, Mainspring designs, manufactures and delivers its products to customers across the U.S. today, and we’re quickly scaling for international expansion.
Inspired by our vision of the affordable, reliable, net-zero carbon grid, Mainspring is rapidly expanding within the $816B global electricity equipment market, and we’re hiring the best talent to meet growing customer demand around the globe. We welcome a broad range of backgrounds, experiences, and talents to bring fresh perspectives and ongoing innovation to our customers.
We are looking to build relationships with people who share our values:
Pragmatic Optimism. Building a new category of world-class power generation requires the optimism of ambition and creativity, balanced with practicality to solve problems efficiently. The challenges that arise are opportunities for growth.
Excellence without Ego. We bring expertise and commitment to creating the best customer experience, from sales to deployment and service, just as we apply deep technical rigor to building and delivering world-class products. We strive for excellence and behave as leaders with the humility to acknowledge our challenges, both collectively and as individual contributors.

Do you have a knack for diagnosing and redesigning critical electrical subsystems to eliminate persistent field issues?
Have you ever invented a tool or changed a process just to make routine installation or service faster and easier?
If you're obsessed with solving real-world design challenges, especially within complex electromechanical power generation equipment, then this role is built for you. Mainspring Energy is seeking a Continuous Improvement Engineer focused on electrical harness and cable design to lead product improvement efforts across field and production systems. You will work embedded on site at a contract manufacturer in Monterrey, Mexico to address design and manufacturing issues at their root. You will redesign critical components for durability and ease of service, and integrate your findings back into the development process to ensure the long-term reliability and manufacturability of our products.
Core Responsibilities
- Lead the root cause analysis of harness and cable related field failures using data from diagnostics, and hands-on testing.
- Redesign or re-engineer components, connectors, routing schemes, or retention strategies to eliminate failures, reduce costs, or improve serviceability.
- Work closely with design engineering, manufacturing, and quality teams to ensure that changes are thoroughly tested and validated with short feedback cycles.
- Collaborate with NPI, manufacturing quality, and supply chain teams to ensure solutions are optimized for production, vendor capabilities, and field service.
- Predict and prevent failure modes by applying deep understanding of mechanical/electrical system interactions, tolerance stack-ups, and real-world use conditions.
- Implement feedback loops from field issues into design standards and engineering processes to continuously improve product quality and reduce recurrence.
- Create and manage internal improvement systems that embed learnings into manufacturing process flow and future design development efforts.
- Support development of service tooling, testing fixtures, or diagnostic aids as needed for improved deployment and serviceability.
- Travel to HQ in Menlo Park, CA required once per quarter
Qualifications
- BS or MS in Mechanical Engineering or similar technical field
- Senior Level: BS + 6 years, or MS + 5 years in industry roles focused on electrical hardware and systems
- Hands-on experience with cable and harness systems, including routing, strain relief, shielding, termination, and connector selection
- Proven ability to use data-driven root cause analysis to solve complex, cross-functional design issues
- Experience addressing and resolving field and production issues.
- Knowledge of DFM/DFA principles and quality system tools (PFMEA, 8D, CAPA, etc.)
- Deep understanding of tolerance stack-ups and use of CMMs in inspection processes.
- Familiar with manufacturing methods including of the following: crimping, potting, stamping, sheet metal, hydroforming, welding, machining, and fabrication.
- Proficient in SolidWorks or comparable CAD package; PDM experience preferred
- Experience with structural FEA and/or electrical system simulation tools is a plus
- Passion for building robust, field-ready solutions with high reliability and serviceability
- You must have be able to travel to the USA and a high level proficiency in English. You understand culture differences and have track records working collaboratively on technical projects between the USA and Mexico.
