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
