Noah Eisen
Hi, I'm Noah, an engineer based in San Francisco with a background in Computer Science and Mathematics from the University of Michigan. Over the past decade, I've led teams and shipped projects at companies like Google, Waymo, Roblox, and Faire. My experience spans infrastructure and product development, with a consistent emphasis on clean code, maintainable systems, and thoughtful architecture.
Career Timeline
Roblox
Roblox is an online platform for games and immersive social experiences that connects players and creators globally. Some key achievements:
- Served as Holiday Readiness DRI for all 10 Social Pods and engineered a graceful degradation system now adopted across 15 services; increased system capacity by 10% for peak traffic events.
- Led bi-weekly architecture design reviews for 3 pods to ensure engineering decisions were long-view aligned.
Faire
Faire is an online wholesale marketplace that connects retailers and brands globally, empowering small businesses to compete with major retailers such as Amazon and Walmart. In a dynamic startup environment, my role has evolved significantly, with key achievements including:
- Authored technical vision document for Faire's payment systems. Initiated and drove critical projects, such as extracting a payment service and developing a SQL-based invariant validation system. These systems eliminated payment-related SEVs.
- Served as Senior Engineering Manager and tech lead for the Shipping team, overseeing 8β12 engineers. Developed a long-term technical strategy to optimize shipping costs and improve system stability. Delivered +0.25pp to contribution margin on $2B GMV.
- Led 5 person tiger team to build Volume Pricing (akin to airline loyalty programs) from design to launch in under two months.
- Drove org-wide cultural transformations across 300+ engineers by leading several cross-functional High-Performance Culture working groups, raising engineering standards and execution velocity.
Waymo
Waymo is an Alphabet company focusing on the development of self-driving technology. I worked on the Fleet Infrastructure team where I was the tech lead for the OpsApp, an internal Android app that is used by 1000+ safety drivers daily. Some highlights include:
- Tech lead of 7 person team, including 3 engineers, a product manager, a product operations specialist, a technical program manager, and a UX designer.
- Received early promotion to Senior Software Engineer within first year of joining.
- Optimized data path from the self-driving car to the phone to achieve sub-300ms latency in support of streaming real-time telemetries to the safety driver.
- Co-authored this patent based on my work designing and building the tool suite that enabled roadside assistance team to navigate to a self-driving car on public roads within minutes of an incident.
gRPC is Google's next-gen RPC system, built from the ground up in open source. gRPC is a highly performant system built around a simple yet powerful wire protocol. The library provides idiomatic APIs in nine supported languages. Through 250+ pull requests, and even more internal changes, I have contributed mainly to gRPC's C core. I have also made significant contributions to the C++ and Python wrapped layers. Some highlights include:
- Created the team's internal benchmarking framework, automatic regression detection system, and performance dashboards.
- Migrated TensorFlow's distributed runtime to use gRPC internally at Google.
- Implemented connection-level monitoring feature for the C++ stack, which exports critical debugging data of live services and presents them in a simple HTML page.
- Co-authored RFC for gRPC client retries in 2017. It is now implemented across all language stacks.
- Created and delivered 40 minute tech talk on gRPC performance at KubeCon.
Bloomberg
Full stack internship on the infrastructure team. Key accomplishments include:
- Created multi-tiered tool (frontend UI, service layer, backend task) for Bloomberg developers to aid in the task of debugging and killing haywire processes on production machines.
- Developed a program to track the master logfile on specific production machines and raise alerts and tickets automatically based on previous decisions.
- Won first place in algorithmic coding competition among all of the interns.
TAPP TV
Freelance programming work focused on social media data analysis and audience research. Key contributions include:
- Collaborated with team of freelance coders to create several methods of exploiting Twitter data in order to gauge audience interest and find potential markets for celebrity TV channels.
- Designed and developed a program that uses the Twitter API to construct graphs from follower/following relationships, then performs various metrics on the data (PageRank, HITS, etc).
Jump Trading, LLC
Quality assurance internship at a high-frequency trading firm in Chicago. Key accomplishments include:
- Developed an automated testing wrapper to validate company software responsible for sending orders to the BATS exchange.
- Planned and executed comprehensive set of manual tests on a program providing a live market feed from the exchange.

Other Interests
Movies
I'm an avid film enthusiast and maintain a detailed log of my movie watching on Letterboxd. I have rated 13 films this year and 885 since starting to use the site.
Project Hail Mary (2026)
Watched on 2026-03-23
When I read the book a few years back the first thing I said was "this would work better as a movie" and you know what that was a great call.
Almost certainly would have been 4+ stars if I had seen this without knowing the plot ahead of time. Someone Andy to skip the prose and go right to a screenplay for the next one.
Books
I love reading and track my books on Goodreads. I have read 6 books this year and have rated 286 since I started using the site.
Wild Dark Shore

I'm done reading climate fiction unless it's written by Richard Powers.
