Onsite linear generators for scalable power
Mainspring Energy manufactures and delivers fuel-flexible, low-emissions local power solutions that rapidly add new capacity and deliver reliable, affordable, and sustainable electric power. The company began commercial shipments of its Mainspring Linear Generators in 2020 and today has hundreds of megawatts in advanced development and field operations for leading Fortune 500 companies, data centers, and utilities. Mainspring also partners with global energy leaders including AEP, NextEra Energy Resources, Schneider Electric, and more.
The core values that ground our work, guide our decisions, and connect us together:
Create, refine, and maintain detailed 3D CAD models and 2D engineering drawings for COTS parts as well as designs for product and manufacturing tools
Execute on high volumes of CAD queue tickets to incorporate engineering requests into 2D fabrication drawings, 3D models, and BOMs accurately and efficiently within SolidWorks and PLM
Perform self-reviews and peer reviews to ensure drawings meet ANSI standards and internal requirements before releasing files via PLM
Support maintenance of reference assemblies, updating metadata, fix and repair broken model mates, defeature complex vendor models, and perform rebuilds for complex assemblies
Assist engineers with SolidWorks questions on internal channels and support new documentation and continuous improvement initiatives
4-6 years or BS in Mechanical Engineering with 3-5 years of industry experience in a drafting role
Strength in SolidWorks or a comparable CAD package, modeling, large assembly management, and experience with some level of PDM/PLM model and drawing release workflows
Demonstrable experience applying ANSI/ASME standards for dimensioning, datums, GD&T application, AWSweld symbols and sheet metal callouts
Experience maintaining revision-controlled Bills of Materials and managing metadata fields
Experience documenting department and CAD processes
Experience debugging issues related to SolidWorks, release processes, industry standards and the ability to mentor colleagues on resolving these issues
Ability to execute moderately difficult CAD tasks carefully, communicate progress, and incorporate feedback from others on the team
Clear verbal and written communication skills in English and Spanish to interact with US-based and local engineering teams
A willingness to ask questions, learn company processes, and build practical engineering judgment
Experience working on tolerance analyses on parts and assemblies is a plus
Exposure to manufacturing processes such as machining, sheet metal, welding, casting, molding, additive manufacturing, or assembly and ability to identify and resolve design for manufacturability issues is a plus
Interest in energy systems, engines, generators, compressors, pumps, thermal systems, fluid systems, structures, electromechanical systems, or industrial equipment
Onsite linear generators for scalable power
Mainspring Energy designs and ships onsite linear generators that produce electricity for commercial and industrial customers, data centers, utilities, and microgrids. The kit uses a straight-line motion that is converted into electric current by magnets moving through copper coils, driven by a flameless, low-temperature air-and-fuel reaction with only two moving parts and an oil-free air-bearing. The system is fuel-flexible, handling natural gas, biogas, hydrogen, ammonia, and propane, and it scales from about 250 kW to more than 100 MW, with near-zero NOx and no after-treatment required. The company sells power as a service, enabling installations with no upfront cost and ongoing payments based on energy use, aiming to lower operating costs and increase energy resilience for its customers.
