Staff Engineer Embedded Firmware

Role Overview

We are seeking an Embedded Linux Firmware Engineer to develop next-generation Intelligent PDUs (Power Distribution Units) used in Audio/Video racks, enterprise IT racks, and edge infrastructure environments.

This role focuses primarily on embedded Linux application firmware, middleware services, backend feature development, and embedded web UI integration. The engineer will build customer-facing PDU functionality such as outlet scheduling, monitoring, telemetry, configuration management, sensor integration, and network management services by leveraging BSP and Hardware Abstraction Layer (HAL) APIs.

The ideal candidate has strong experience in embedded Linux systems, C/C++ development, networking protocols, and feature-level embedded application development.
