Title:  Sr Firmware Engineer

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
