About The Position

The Sr Engineer, Embedded Firmware will drive firmware design from inception through customer deployment, supporting hardware validation and integration. The role focuses on embedded firmware for high-speed SerDes interfaces and electronic/photonic subsystems, including control algorithms for photonic circuits and firmware requirements for multi-chip package systems. The engineer will support silicon power-on and bringup, debug hardware-firmware interactions, collaborate across product development teams, and maintain technical documentation.

Requirements

• Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field.
• At least 3 years of relevant industry experience.
• Expertise in bare-metal embedded firmware development and strong programming skills in C.
• Experience with microcontrollers and firmware debugging tools.
• Proficiency with version control workflows such as Git, modern firmware development tools, and CI/CD tools.
• A hands-on, proactive approach and ability to work in a fast-paced, dynamic startup environment.
• Silicon bringup experience.
• Experience scripting with a high-level language such as Python.
• Experience with Make-based build flows.

Nice To Haves

• Ability to own the architecture and development of firmware modules from scratch.
• Experience in embedded firmware development for high-speed electronics and photonics applications.
• Silicon bringup experience for high-speed SerDes and photonics applications.

Responsibilities

• Design, develop, and optimize embedded firmware for high-speed SerDes interfaces and electronic/photonic subsystems.
• Collaborate with analog/mixed-signal, digital, and photonic block designers to develop control algorithms for photonic circuits and establish micro-architecture and embedded requirements for multi-chip package systems.
• Write unit and integration tests for firmware modules, participate in firmware code reviews, and maintain firmware quality through CI/CD practices.
• Develop and execute firmware test code for initial silicon power-on and bringup; debug hardware-firmware interactions at first silicon.
• Partner with hardware, validation, systems, and software teams throughout the product development lifecycle.
• Maintain technical documentation, including APIs, firmware architecture documents, module specifications, and build/release notes.
