Impinj Tech Stack

RAIN RFID platform connecting physical items to enterprise applications

Information Technology & Services Seattle, WA 201–500 employees Founded 2000 Public Company

Impinj is a public RFID platform company (NASDAQ: PI) using RAIN wireless technology to tag and track physical items—apparel, parts, logistics, assets—at enterprise scale. The tech stack reflects a hardware-software hybrid: embedded Linux, C/C++, ARM, plus data science (PyTorch, TensorFlow, scikit-learn) for signal processing and RF modeling. Hiring is heavily engineering-focused with 7 active roles in that department, concentrated at the intern and principal levels—a pattern that suggests either on-boarding new talent at scale or staffing specialized RF/algorithm work.
