2022-04-05T23:36:56-04:00 X, The Moonshot Factory
Photonics Engineer
Hardware Engineering
Mountain View, CA

X is Alphabet’s moonshot factory. We are a diverse group of inventors and entrepreneurs who build and launch technologies that aim to improve the lives of millions, even billions, of people. Our goal: 10x impact on the world’s most intractable problems, not just 10% improvement. We approach projects that have the aspiration and riskiness of research with the speed and ambition of a startup.

About the Team:

We are exploring automated design for electromagnetic devices. This capability could enable applications ranging from integrated photonics to metasurfaces, and requires technical developments in ultra-large-scale simulators, novel optimization schemes, and prototyping/fabrication capabilities.

 

About the Role:

The position seeks motivated individuals that enjoy working in a small, interdisciplinary team environment, have a growth mindset, a passion for problem-solving directed at achieving meaningful breakthroughs in technology, and are comfortable with uncertainty and exploration.

 

How you will make an impact:

  • Own our silicon photonic component tapeout workflow including: 
    • Layout design: Build layouts to fabricate our custom designs including PDK components, test structures and PCMs to extract fabrication data. 
    • Verification: Verify custom design performance using finite difference time domain (FDTD) and add eigenmode expansion method (EME) to model the performance of silicon photonic components. Ensure our layouts pass DFM (Design for Manufacturability) and DFT (Design for Testability) requirements.
    • Foundry & measurement labs: Work with fabrication vendors (foundries or research fabs) and measurement labs to build chips and measure their performance.
    • Result analysis: Compare the results of the simulation and experimental data to improve our future device designs. 
  • Inform and develop computational fabrication models (including variability) by:
    • Designing and characterizing physical test structures in the layouts
    • Analyzing and translating fabrication SPC data from the layouts
    • Identifying the most relevant approaches in the literature.
  • Using your knowledge of the photonics domain, identify and explore additional high-value targets for our design efforts. Work with the design team to make them a reality. Contribute to the expansion of our IP portfolio through patent filing
  • Using your knowledge of the photonics domain, identify and explore additional high-value foundry vendors to partner with. Work with the partnerships team to make it  reality.
  • Work with software engineers to guide:
    • Development of computational fabrication models in our design process
    • Development of new simulation/optimization tools and capabilities
    • Workflow automation efforts

 

What you should have:

  • Understand the general testing principle in photonics with some basic hands-on test experience.
  • Strong communication skills with the ability to explain complex technical concepts to non-experts. Ability to effectively collaborate with software engineers.
  • MSc. or PhD. in physics, electrical engineering, mathematics, computer science, artificial intelligence or related fields.
  • 2 years of industry scale tapeout experience related to design, fabrication, and testing of integrated photonic components.
  • Expert understanding of CMOS manufacturing process steps and constraints on the design of photonic devices
  • Experience with production scale of silicon packaging
  • Experience with optical proximity correction and its simulation

 

It would be great if you also had these:

  • Experience developing photonics fabrication and testing capability from the ground up.
  • Experience in bringing a photonics product from conception to mass production stage.
  • Proven record of Python programming experience. You must be productive in a code-driven environment that doesn’t rely on GUIs.
  • Strong background in optoelectronic device physics, as it relates to lasers, waveguides, modulators, detectors, etc.
  • Experience with fab process integration.
  • Strong software skills, with experience scripting and automating commercial, open source, and custom-developed software tools.
  • Startup, skunkworks, or other entrepreneurial experience. Experience seeking out and pivoting based on new market or engineering information. 
  • Proven record of contributions to open source packages for graphics, layout, simulations, HPC
  • Experience with the following PDA tools: IPKISS, Lumerical, Meep, Calibre, Virtuoso.
  • Experience running, monitoring and analyzing machine learning jobs.

At X, we don't just accept difference - we celebrate it, we support it, and we thrive on it for the benefit of our employees, our products and our community. We are proud to be an equal opportunity workplace and is an affirmative action employer. We are committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity or Veteran status. We also consider qualified applicants regardless of criminal histories, consistent with legal requirements.

Voluntary Self-Identification

For government reporting purposes, we ask candidates to respond to the below self-identification survey. Completion of the form is entirely voluntary. Whatever your decision, it will not be considered in the hiring process or thereafter. Any information that you do provide will be recorded and maintained in a confidential file.

As set forth in this company’s Equal Employment Opportunity policy, we do not discriminate on the basis of any protected group status under any applicable law.

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Veteran Status
Why are you being asked to complete this form?

We are a federal contractor or subcontractor required by law to provide equal employment opportunity to qualified people with disabilities. We are also required to measure our progress toward having at least 7% of our workforce be individuals with disabilities. To do this, we must ask applicants and employees if they have a disability or have ever had a disability. Because a person may become disabled at any time, we ask all of our employees to update their information at least every five years.

Identifying yourself as an individual with a disability is voluntary, and we hope that you will choose to do so. Your answer will be maintained confidentially and not be seen by selecting officials or anyone else involved in making personnel decisions. Completing the form will not negatively impact you in any way, regardless of whether you have self-identified in the past.
