My name is Andrew Rossignol and I am a Staff Software Engineer at Google.
Hobbies
I have too many hobbies. I enjoy spending time tinkering with vintage audio, lithium batteries, electric vehicles, 3D printing, electronics, embedded software, Linux servers, and more.
As a creative outlet, I maintain a blog called TheResistorNetwork and companion YouTube channel. When I decide that a project is large or interesting enough to warrant a blog post, I will post over there. This website captures smaller projects, one-liners, photos of interesting projects and more.
Career
I have held a number of jobs over the years. Most of those jobs have been technical or engineering-related but I have also had some opportunities to work with my hands and coordinate youth activities over the years.
I love working with technology and am a generalist. I have worked on everything from embedded systems to business automation web applications and everything in between.
I have been working for Google since June 2014 and have contributed to a number of exciting projects since then.
Jamboard
In June 2014 I joined Google and worked on Jamboard out of the New York City
office. I worked on integration of touch drivers with Android, working with
the uinput interface. I also worked heavily with OpenGL and found numerous
opportunities for performance optimizations in the rendering stack.
I developed the first integration with Google’s video conferencing solution known as GVC. This was a self-motivated weekend hackathon and later went on to become a core feature of the product.
Android
In October 2015 I moved to Mountain View, CA and joined the Android team. I accepted this role to apply my experience with embedded systems to the sensor hubs of mobile phones. I was on the team for Nexus 5X/6P and Pixel 1 through 4. I also launched two watches and developed functionality that reduced screen-on power consumption by a factor of 10. This was adopted by other vendors.
As part of the sensor hub project, a new platform known as Context Hub was designed to standardize the APIs available to algorithms running on low-power sensor processors.
Tidal
In February 2019, I moved to Google X to work on a project known as Tidal. On this team, I became the Tech Lead Manager of the System Software team. This team is responsible for a variety of functionality including device firmware, factory test software, web control/montoring, application scheduling, working with image sensors and more.
One of my more prominent contributions was a complete realtime firmware solution responsible for power monitoring, sensor readout and realime control over motors and lights attached to the system.
gChips
In December of 2021, I decided to leave Tidal to spend more time working closely with embedded systems and accepted a role as lead of the Image Signal Processor (ISP) Silicon Validation (SiVal) team. This team is responsible for validating the design of the ISP used in the Tensor SoC. This covers a large body of work including part characterization, pre-silicon emulation and working with hardened complex algorithms to validate their correctness and performance.
L-3 WESCAM
Prior to Google I worked for L-3 Wescam in Burlington, Ontario. I was hired as a manufacturing engineering student to develop electrical test fixtures for the ETAD (Eelectrical Test Automation Development) group. Within a few weeks I demonstrated my software capabiltiies and was dedicated to design a new Manufacturing Execution System (MES) to digitize documents used while building camera systems on the production line.
This effort was a massive success, was deployed company-wide and resulted in huge financial savings for the company.
Once MES was feature complete, I turned my attention to a number of other business applications including Shipment Management System (SMS) to manage the shipping/receiving dock and AssetTracker to track tool calibration on the production line.
