Summary

We are seeking a Full Stack Software Developer to design, build, and own the internal software systems that power our manufacturing operations. This is a high-autonomy role spanning the entire stack; from front-end dashboards and back-end services to equipment-level communication protocols where you will drive architecture decisions and deliver end-to-end solutions across MES/RMS integrations, production monitoring tools, and SECS/GEM host software. The ideal candidate pairs strong C#/.NET fundamentals with the initiative to define systems in a growing environment, not just maintain them.

You will join a team of approximately ten engineers within the MIS department, working alongside MES, database, and systems engineering colleagues in an open office environment with occasional time in cleanroom manufacturing areas. As AOI scales U.S. production capacity to meet accelerating AI datacenter demand, this role will be central to building the software infrastructure that supports higher throughput, better yield and yield visibility, with more reliable equipment automation.
