Sr. Staff Engineer, Embedded Firmware
Ayar Labs is revolutionizing the world of optical interconnect technology with our cutting‑edge electro‑photonic chips! We are seeking an exceptional Firmware Engineer to drive firmware design from inception to customer deployment, ensuring seamless hardware validation and integration.
This is a unique opportunity to leverage your expertise in embedded systems, multi‑chip package environments, and high‑speed Ser Des to shape the future of optical interconnect.
Essential Functions:- Design a general computing platform:
Initialize and control the platform's hardware (like the CPU, memory and I/O devices) and load the operating system, making the platform ready for use. - Firmware Architecture:
Collaborate closely with embedded firmware, system hardware and AISC engineers to develop sophisticated platform solutions and meet requirements for our digital and photonic multi‑chip and laser systems. - Drive platform firmware development:
Design, develop, and optimize firmware for controlling complex systems with the electronic‑photonic chips and laser. - Provide Technical Leadership:
Mentor and guide junior engineers, contributing to their professional growth and development. - Collaborate Cross‑Functionally:
Partner effectively with diverse teams, including hardware, software, validation and systems engineers, to achieve project goals.
- Bachelor's in Electrical/Computer Engineering or a related field with 6+ years of experience.
- Proven expertise in bare‑metal platform firmware development, with strong programming skills in C, C++ and python.
- Industry experience with CMIS (Content Management Interoperability Services) communication protocol.
- Hands‑on, proactive approach with the ability to thrive in a fast‑paced, dynamic startup environment.
- Experience with various microcontrollers (e.g., STM, Microchip) and firmware debugging tools.
- Experience with hardware schematics.
- Experience with driver development (e.g., ADC/ DAC).
- Experience with communication protocols (e.g., I2C, SPI, USB, UART).
- Proficiency with modern version control workflows (e.g., Git).
- Familiarity with project management tools (JIRA), and CI/CD tools.
- Experience in platform firmware development for laser applications.
- Experience in firmware development for high‑speed electronics and photonics applications.
- Experience in scripting with high level language like Python.
- Experience with Make‑based build flows.
- Ability to own architecture and development of firmware modules from scratch.
Salary range: $170,000 - $223,000
