Job Description

Roles & Responsibilities

Role Overview

We are looking for a hands-on Embedded Systems Engineer to join the Hardware team. You will design, develop, and maintain firmware across three core domains that are central to Blu EV's next phase of growth: swapping station control systems, battery management systems, and IoT connectivity. Working closely with the Hardware Team Leader and field operations teams.

• Design, develop, and maintain embedded firmware across the Blu EV ecosystem, covering swapping station controllers, battery management systems, and IoT connectivity layers.
• Implement and debug communication interfaces between hardware subsystems to ensure reliable data exchange, fault detection, and real-time telemetry.
• Manage firmware update processes for deployed field units, supporting both remote and on-site update workflows.
• Investigate hardware and firmware anomalies in the field, correlating log data and telemetry with physical findings to identify root causes and drive corrective actions.
• Ensure security best practices are applied across all connected devices, including encrypted communication, device identity management, and certificate lifecycle.
• Produce clear technical documentation for firmware modules, communication protocols, and diagnostic procedures.
• Support field team training on diagnostic tools, monitoring interfaces, and log extraction workflows.
• Coordinate with hardware and software suppliers on firmware integration, protocol clarification, and technical issue escalation.
• Contribute to hardware-software co-design decisions for future platform generations.
