POSITION SUMMARY

We are seeking a senior firmware engineer to design and develop Power Management Controller (PMC) systems used in hyperscale power shelf solutions.

The PMC is an embedded Linux-based system controller responsible for monitoring, aggregating, and managing multiple power modules (PSU/BBU) and exposing system-level services via Redfish, Web UI, and network interfaces.

This role focuses on system-level firmware architecture, data processing pipelines, and power system control, rather than low-level driver development.

KEY RESPONSIBILITIES

System & Feature Ownership

Own the design, implementation, and lifecycle management of PMC software components
Lead development of new PMC features aligned with customer and platform requirements
Define and maintain software architecture for power monitoring and control systems

Power System Monitoring & Control

Develop firmware to monitor and control PSU / BBU modules via PMBus / Modbus
Implement telemetry collection (voltage, current, power, temperature, alarms, etc.)
Manage aggregation of power data at shelf/system level

Data Architecture & Software Framework

Design and implement PMC software layers including

Data processing (polling, validation, reporting)
Data management / warehousing
System actions (configuration, housekeeping, firmware update)

Define and maintain system models such as

PSU / shelf / manager / FRU resources

Platform & Interface Development

Develop and integrate system interfaces

Redfish API / RESTful services

Web UI / GUI

SSH / CLI tools

Enable communication over

Ethernet (TCP/IP, UDP)

I2C / PMBus / RS232 / Modbus

Software Quality & Collaboration

Perform code reviews, refactoring, and continuous improvement
Support system integration, validation, and release activities
Work closely with FAE, customers, and cross-functional teams
Collaborate with global PMC engineering teams (e.g., Philippines-based team) to share resources, align system architecture, and co-develop features across regions

REQUIRED SKILLS

Core Technical Skills

Strong experience with embedded Linux systems (application layer focus)
Proficiency in C/C++ for system-level firmware
Experience with Python / scripting for system integration and automation
Solid understanding of software architecture and system design

Communication & Protocols

Familiarity with

PMBus / I2C / Modbus

TCP/IP networking
Redfish or RESTful APIs
Experience building system-level services and data models

Domain Knowledge

Experience in one or more

Power systems / power supply / server power infrastructure
System monitoring / telemetry platforms
Embedded system management controllers (e.g. BMC / PMC)

Preferred Qualifications

Experience with OpenBMC / Yocto-based systems

Knowledge of power telemetry aggregation and system-level analytics

Hands-on experience with

Web UI integration

Firmware update / lifecycle management

Experience in hyperscale or datacenter power systems

EDUCATION

Bachelor’s or Master’s degree in Electrical Engineering, Computer Science, or related field
