Software Engineer - Infrastructure and Factory Systems

Software Engineer, Infrastructure (C++) - Build the Backbone of a Software-Driven Factory Billerica, MA | On-site Opportunity Summary A well-funded manufacturing startup is building a software-driven foundry that delivers precision metal castings to aerospace, defense, and industrial customers far faster than traditional suppliers. Every machine, operator, and production job depends on the software platform that ties the factory together. You will own that platform. This role builds the backend services, databases, and tooling that connect machines and workflows, and owns the build systems, CI/CD, and cloud infrastructure that keep both the software team and the factory running. You will report to the CTO and work on-site alongside the people who rely on your systems. About Us We are an early-stage, well-capitalized advanced manufacturing startup rebuilding domestic metal casting capacity for aerospace, defense, and energy customers. Backed by leading venture firms and strategic aerospace and defense investors, the company has a production foundry up and running, is shipping parts to customers, and plans to bring additional foundries online as demand grows. The founding team comes from top commercial space and metal additive manufacturing companies, and every employee works on-site, close to the physical process.
