Job Summary

This role is responsible for leading the architecture, design, and development of low-level connectivity firmware for HP printer platforms, with a focus on Wi-Fi, Bluetooth, Ethernet, and NFC subsystems.

As a subject matter expert, the engineer drives end-to-end connectivity solutions, working across hardware interfaces, firmware, and networking layers to ensure robust, secure, and high-performance device connectivity in complex real-world environments.

Responsibilities

• Lead the design, architecture, and implementation of low-level firmware and drivers that interface with connectivity chipsets (Wi-Fi, Bluetooth, NFC).

• Own and drive integration of connectivity subsystems using hardware interfaces such as:

• SDIO, USB, UART, I2C, SPI

• Architect and optimize firmware components responsible for:

• Wireless module bring-up, initialization, and configuration
• Power management and system-level coordination with platform firmware

• Provide deep technical leadership in integration of third-party connectivity modules, including vendor driver stacks and SDKs.

System & Cross-Layer Ownership

• Lead debugging and root cause analysis across the full networking stack:

• Physical layer through application-layer protocols

• Drive resolution of complex, cross-layer issues involving:

• Wi-Fi, Bluetooth, Ethernet, and IP networking interactions
• Client device interoperability and router ecosystem behavior

• Analyze and troubleshoot packet flows including:

• Ethernet and Wi-Fi framing
• MAC layer behavior and MAC address handling
• IPv4/IPv6 addressing, routing, and packet delivery
• Multicast and unicast communication behavior

Protocols & Security Leadership

• Provide subject matter expertise in:

• IEEE 802.11 (Wi-Fi), Bluetooth (BLE), Wi-Fi Direct (P2P), Wi-Fi Aware (NAN)

• Lead implementation and integration of security protocols, including:

• WPA3, 802.1X (EAP), TLS/SSL

• Drive compliance and interoperability across standards bodies (e.g., Wi-Fi Alliance, Bluetooth SIG)

Diagnostics, Reliability, and Field Excellence

• Define and drive advanced logging, telemetry, and diagnostics strategies to enable efficient field issue triage and root cause analysis.

• Lead investigations of customer-reported connectivity issues, including:

• Reproduction, root cause analysis, and resolution across firmware and network layers

• Establish best practices for connectivity reliability, self-healing, and performance optimization

Technical Leadership & Influence

• Act as the connectivity firmware domain expert across programs and organizations

• Lead or significantly influence architecture decisions for new platforms and connectivity features

• Drive alignment with cross-functional teams:

• SoC vendors, module vendors, platform firmware teams, OS/client teams

• Mentor engineers and elevate team capability in connectivity firmware development

• Contribute to long-term strategy and innovation in printer connectivity

Education & Experience

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

• Typically 7–10+ years of experience in embedded firmware development, with deep expertise in connectivity and networking

• Proven experience leading technically complex firmware projects involving hardware-software integration

• Proven ability to lead remote collaboration and drive cross-geographical teamwork across across different time zones, including U.S. Pacific Time and India

• Flexibility to support work across global time zones and travel occasionally as required.

Knowledge & Skills (Expert-Level Connectivity Focus)

Embedded & Low-Level Firmware

• Expert-level proficiency in C/C++ for embedded systems

• Strong experience with RTOS and/or embedded Linux platforms

• Deep understanding of firmware architecture, driver development, and hardware abstraction layers

Wireless & Networking Protocols

• Deep expertise in:

• EEE 802.11 (including MAC layer behavior)
• Bluetooth (Classic and BLE)
• Wi-Fi Direct and Wi-Fi Aware

• Strong understanding of:

• TCP/IP stack (IPv4/IPv6)
• DHCP, DNS, mDNS, and service discovery mechanisms

Networking Fundamentals

• Strong-level understanding of:

• OSI model (Layers 1–7)
• Ethernet and Wi-Fi frame structures
• MAC layer behavior and MAC address usage
• IP addressing, subnetting, routing, and packet delivery
• Multicast vs unicast communication dynamics

Hardware Interface Protocols

• Strong experience with:

• SDIO (WLAN/BT combo modules), UART, USB, I2C, SPI

• Deep understanding of:

• Interrupt handling, DMA, concurrency, and performance optimization

• Experience debugging hardware/firmware interactions using low-level tools (logic analyzers, bus analyzers)

Security & Authentication

• Good understanding of:

• WPA2/WPA3
• 802.1X (EAP methods)
• TLS/SSL and certificate-based authentication
• Secure Boot fundamentals

Debugging & System Analysis
