Role summary

We are seeking a Senior Software Engineer to tackle complex problems at the intersection of statistics, machine learning, and scalable systems. You will develop quantitative models for evaluation challenges, ensuring mathematical rigor and experimental validation. Responsibilities include designing and building automation for evaluation infrastructure, enhancing efficiency and scalability, and collaborating with cross-functional teams to deliver data-driven evaluation products. The role requires fluency in implementing algorithms for large datasets and adapting research techniques to applied problems, with 3-5 years of experience in large code bases (C++, Python, SQL), statistical analysis, data pipelines, and code maintainability. A BS in a quantitative field is required, with a PhD preferred.

Waymo is an autonomous driving technology company with the mission to be the world's most trusted driver. Since its start as the Google Self-Driving Car Project in 2009, Waymo has focused on building the Waymo Driver—The World's Most Experienced Driver™—to improve access to mobility while saving thousands of lives now lost to traffic crashes. The Waymo Driver powers Waymo’s fully autonomous ride-hail service and can also be applied to a range of vehicle platforms and product use cases. The Waymo Driver has provided over ten million rider-only trips, enabled by its experience autonomously driving over 100 million miles on public roads and tens of billions in simulation across 15+ U.S. states.

As a Software Engineer, you will solve ill-defined problems at the intersection of statistics, machine learning, and scalable systems engineering. You will develop creative quantitative models to address eval challenges, while providing rigorous mathematical and experimental proof of the correctness and statistical efficiency of your solutions.

You will:

Tackle ill-defined, ambiguous problems and reduce complex systems into tractable quantitative models.

Develop statistical techniques that enable our evaluation pipelines to deliver better signals with fewer resources.

Design and build automation to enhance the efficiency and scalability of our evaluation infrastructure.

Collaborate with other engineers, data scientists, product managers, and the leadership team to deliver evaluation products and help make data driven decisions.

Champion code health and best practices in a large and complex code base.

You have:

BS in Math, Physics, or another quantitative field

Fluency in implementing statistical, ML, and general mathematical algorithms for large datasets

Experience adapting techniques in research papers to applied problems

Strong self-motivation and comfort with ambiguity to navigate complex systems and pursue open-ended problems to completion

3-5 years of experience with

Navigating and modifying a large code base containing a variety of languages, such as C++, Python, and SQL

Performing statistical analyses

Building data processing pipelines

Writing, reviewing, and merging code following industry standards for code health and maintainability

We prefer:

PhD in a quantitative field

Experience programming in C++ and Python

Experience developing, evaluating, and deploying products at scale

3
Longest Substring with Two Distinct Characters Find the longest substring with at most two distinct characters. Input: s = "ccaabbb" Output: 5 Explanation: The substring "aabbb" contains exactly two distinct characters and has a maximum length of 5.

4
Alien Dictionary Order Derive the alien dictionary order from a sorted list of alien words. Input: words = ["z","x","z"] Output: "" (Empty String) Explanation: The letter 'z' cannot come before 'x' and then suddenly after 'x', creating a cycle and making the dictionary invalid.

5
Palindrome After Deleting One Character Determine if a string can be a palindrome after deleting at most one character. Input: s = "abc" Output: FALSE Explanation: Deleting any single character leaves either "ab", "bc", or "ac", none of which result in a valid palindrome.
