Senior Machine Control Software Engineer

The Company Halo Industries has invented a technology to replace a decades-old semiconductor material wire saw slicing process that wastes billions of dollars annually in high-value materials. Halo's laser-based technology eliminates this waste from the silicon carbide (SiC) substrate manufacturing process, delivering improvements in both material cost and performance, while enabling accelerated growth for a diverse set of high-growth application markets, including the electric vehicle, grid infrastructure, industrial HVAC and other high-voltage power electronics sectors. Halo originally spun out of Stanford University in 2014, acquiring a significant series A round of VC funding in 2020 following the successful demonstration of the company's precision material slicing equipment. Having recently closed on an $80M+ B round of VC funding, Halo is driving the fast-scale growth of the company's team and manufacturing operations. Halo Industries is well-funded, deeply engaged with multiple strategic customers, and staged to achieve rapid operational, revenue, and valuation growth. The Opportunity As Halo transitions from R&D to high-volume manufacturing, we are seeking a Machine Control Software Engineer to support the development, integration, and maintenance of equipment control systems for our semiconductor production tools. This role will focus on hands-on software development and system integration, working closely with cross-functional engineering teams. The engineer will report to a senior member of the machine control team and contribute to building reliable, scalable automation systems. Job Description
