About Mainspring Energy

Local power generation for data centers, utilities, industrial & enterprise applications. Fuel-flexible, fast to deploy, high-efficiency, low NOx power. Backed by General Catalyst and Khosla.

About the role

Mainspring Energy has fundamentally redefined onsite power generation. Our breakthrough product—the Mainspring Linear Generator (LGen)—is a completely new category of energy technology. Distinct from an engine, turbine, or fuel cell, the LGen directly converts straight-line motion into electricity using a low-temperature, non-combustion thermochemical reaction.

What they're looking for

  • Experience & Education: Bachelor’s degree in Computer Science or a related field with 10+ years of professional experience, or a Master’s degree with 9+ years in an SDET, Embedded Test, or Software Engineering role
  • Strategic Automation Leadership: A proven track record of leading complex automation projects from design to implementation, combined with the foundational ability to perform deep-dive manual exploratory testing and technical test case design
  • Technical Versatility: Strong hands-on software development experience in Python and C++, with the flexibility to navigate, debug, and contribute to diverse codebases (including Bash scripting) as the project requires
  • Domain Expertise: Professional experience testing and validating systems in at least three of the following areas: Cloud computing, embedded systems, networking, IoT with RTOS, controls, simulations (MIL/SIL/PIL), emulators, or complex algorithms
  • DevOps & Infrastructure: Experience working with containerization and orchestration tools such as Docker, Kubernetes, and configuration management via Ansible
  • Industry Tooling: High proficiency with common industry test and development workflows like Jira, Xray, GitLab, or equivalent tools
