Jule Tech Stack

Grid-independent EV and bus charging with integrated energy storage

Appliances, Electrical, and Electronics Manufacturing Toronto, ON 51–200 employees Founded 2009 Privately Held

Jule manufactures battery-backed EV charging infrastructure designed to operate independently from grid constraints. The tech stack reveals a hardware-first organization: C/C++, ARM, LabVIEW, and RTOS for embedded systems, paired with Go, React, and PostgreSQL for operations and network management. Active firmware work (OTA updates, board support packages, hardware bring-up) and thermal-management challenges indicate Jule is scaling new hardware platforms while managing the reliability demands of deployed systems. The hiring mix—mostly senior and mid-level engineers with one sales role—reflects a product-and-operations-focused phase, not yet revenue-driven hiring.
