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, and Faire. My experience spans infrastructure and product development, with a consistent emphasis on clean code, maintainable systems, and thoughtful architecture.
Career Snapshot
Faire
At Faire - a fast-moving, high-growth startup - I've worn many hats: hands-on engineer, system architect, tech lead, and senior engineering manager. I've led platform work across shipping, payments, and third-party integrations, delivering high-impact features like multi-user account infrastructure, SQL-based invariant validation, and guaranteed shipping pricing. I authored Faire's long-term technical vision for shipping and oversaw complex service extractions in payments. Whether driving strategy or writing critical path code, my focus has been on close patnership with prodcut and building scalable systems that move fast without compromising on reliability.
Waymo
At Waymo, I was on the Fleet Infrastructure team, leading development of OpsApp, an internal Android application used daily by over 1,000 safety drivers. I managed a cross-functional team spanning engineering, product, UX, and operations, and drove initiatives to ensure safety, speed, and reliability across the self-driving fleet. I built systems to stream real-time telemetry with sub-300ms latency, integrated compliance checklists directly into vehicle startup logic, and designed roadside support tooling that enabled responders to locate vehicles within minutes of an incident. I co-authored a patent for my work on the subject.
I started my full-time career at Google as part of the gRPC team, contributing to core C, C++, and Python libraries that power Google's internal and external services. I built benchmarking and regression detection tools, helped migrate TensorFlow's distributed runtime to gRPC, and gave a tech talk at KubeCon on tuning RPC performance .
Bloomberg
Full stack internship on the infrastructure team. Built internal tooling to help debug and kill processes running on production machines.
Side Projects
Newer projects coming soon! In the meantime, you can check out my old website for projects I made many years ago.
Other Interests
Movies
I'm an avid film enthusiast and maintain a detailed log of my movie watching on Letterboxd.
Sinners (2025)
Watched on 2025-04-27
Took a big swing -> scored a big hit. How many genres / tones / styles can one man smoosh into a movie?? But it totally works.
Michael B Jordan really had great chemistry with everyone in this movie, including and above all himself.
Books
I love reading and track my reading progress on Goodreads.
Station Eleven

Re-reading this post-pandy hits a lot harder. The chapters that describe the fallout from the flu went from being interesting sci-fi to fridge-horror what-ifs about the real pandemic.
Such a solid work of literary-ish sci-fi. I could see someone criticizing this book for having an anti-climatic ending, but they would have missed the the fact that it was all about the journey.
ORIGINAL 2017 REVIEW BELOW
I'll always love a well executed, deeply intertwined, mosaic piece.
Read this very shortly after reading The Road, and the astounding differences in tone were fun to think about.
Fitness
I enjoy running and cycling around San Francisco. Here are my most recent workouts:
