JITX

Senior Software Engineer

Berkeley, Ca (Hybrid)

Senior Software Engineer Berkeley, Ca (Hybrid) About JITX JITX is revolutionizing circuit board design by making it code-first. Instead of dragging components around in a GUI, engineers write code (or have AI write it for them) to define their circuit boards. Our solvers handle the low-level details, making hardware engineering massively reusable. We're a ~12-person startup building tools that bring software engineering practices to hardware design. The Role We're looking for a senior software engineer with a strong mathematical and algorithmic foundation who can own significant product areas end-to-end. You'll work on hard computational problems, from design automation algorithms to real-time visualization, shipping features that directly impact how electrical engineers design the hardware that powers the world. You'll be diving straight into our new simulation loop project, a core initiative that tightly integrates our design engine with circuit simulation to catch errors earlier and give engineers faster feedback. What You'll Work On Design Automation Algorithms - Placement, routing, pin-assignment, and geometry generation algorithms for PCBs - Computational geometry and spatial data structures - Constraint solving and optimization Simulation Integration - Integrating industry simulation tools (e.g. Ansys HFSS) into our design flow - Building feedback loops that drive automated design optimization using simulation results - Bridging between our design engine and external solvers to enable closed-loop iteration What We're Looking For Must Haves - Strong algorithmic problem-solving skills: graph/tree data structures, computational efficiency, and parallelism - Mathematical maturity. Comfortable reasoning formally about geometry, linear algebra, or optimization - Solid software engineering
