  • Proactive Collaboration

Job Overview

We have a high-impact opportunity for a Materials and Process Engineer who wants to join a world-class engineering team and help scale production of the Linear Generator. The materials and process team at Mainspring Energy works on complex development projects which are at the intersection of properties, performance and processing of a wide range of materials – non ferrous, ferrous, coatings, graphite, polymers etc.

In this role, you will develop reliable cost effective materials solutions and manage existing solutions through validation testing, process development and deployment on an actual part/subassembly. This is a great opportunity to be part of cross functional projects and collaborate with multiple teams such as Supply chain, Quality, Reliability, Design and Production.

Core responsibilities

  • Lead independent process development and material validation of cast metal components and other mechanical systems in the Linear Generator

  • Collaborate with other members of the Materials and Engineering teams to characterize material properties, identify failure modes, and execute validation tests to meet reliability requirements

  • Create, develop, and optimize material and process specifications related to castings and other mechanical components.

  • Write specifications, process control, and quality control plans for cast and other mechanical components

  • Collaborate with other teams such as mechanical design, supply chain and quality to qualify processes and establish key process controls at manufacturing locations, including casting suppliers

  • Participate in FMEA for design, process, and maintenance

  • Support the Materials and Process team with failure analysis and process development projects across multiple materials and process areas (e.g., coatings, polymers, graphite, joining/welding)

  • Qualifications

  • BS in Materials Science/Engineering or Mechanical Engineering

  • MS + 5 years or PhD + 3 years of industry experience

  • Prior experience with metal casting processes (e.g., die casting, investment casting, sand casting) and their impact on part properties and performance is strongly preferred

  • Fundamental understanding of properties and performance of engineering materials, and basic knowledge of structure-property relationships

  • Broader exposure to other materials and process areas — such as coatings, polymers, graphite, forging, or joining/welding — is a plus

  • Experience with volume production of metal or cast components is highly preferred

  • Working knowledge and experience with FMEA (Failure Mode and Effects Analysis)

  • Demonstrated experience with statistical data analysis and reporting (Matlab/Python, Google Sheets/Excel, Weibull++, etc.)

  • Excellent communication skills, adaptable self-starter, enjoys collaboration in a fast-paced environment


  • Does your experience not meet all of our posted requirements? Studies have shown that some people are less likely to apply to positions unless they meet every listed requirement. At Mainspring, we are committed to building a diverse, inclusive, flexible, and collaborative environment, so if you want to help us transition the world to clean and affordable electricity, and don’t meet all posted requirements for a particular role, we’d still love to hear from you. Mainspring can sometimes be flexible enough to shift responsibilities for the right person, or otherwise identify open or upcoming roles that may better fit your professional background.
