The core values that ground our work, guide our decisions, and connect us together:
At Mainspring, Product Managers sit at the intersection of engineering, sales, marketing, installation, and maintenance. The Project Strategist sits one step further out, at the boundary between the product Mainspring repeats at every large site and the full site a customer is buying. This role defines everything in between, from balance of plant and switchgear to the equipment Mainspring may have to partner to supply and the customer-facing side of site communications and controls. It is the externally facing counterpart to the product owner of that repeatable suite, so a large part of the job is understanding what customers expect a linear generator site to do, how they expect to monitor and dispatch it, and what it has to connect to on their site. Our ideal Project Strategist has developed, engineered, or built power generation sites and can hold a technical conversation with an EPC, a utility interconnection engineer, and a data center owner in the same week. They enjoy taking an ambiguous set of customer expectations and turning it into a project development plan a company can execute and stand behind. Most importantly, they can make strategic decisions about what Mainspring must standardize as part of our site project offering, to reduce variability and increase reliability across sites.
