JITX

About

JITX is a code-first electronic systems design platform that applies software engineering practices to circuit board design. Instead of dragging components in a GUI, engineers write Python—or have AI write it—to define boards, while JITX's solvers handle low-level details like routing, pin assignment, and schematic generation. The platform integrates HFSS simulation into the design loop, using measured results to drive iterative code edits for high-frequency boards. A ~12-person startup, JITX is trusted by Honeywell Aerospace, Lockheed Martin, and OpenAI. The company is hiring a senior software engineer with a strong mathematical and algorithmic foundation to own significant product areas.
