Position Summary...

What youll do...

Cortex Team is Walmarts core A.I. conversational platform powering the vision of delivering the worlds best personal assistants to Walmarts customers accessible via natural voice commands text messages rich UI interactions and a mix of all of the above via multi-modal believeconversationsare a natural and powerful user interface for interacting with technology and enable a richer customer experiences both online and in-store. We are building and designing the next generation of Natural Language Understanding (NLU) services that other teams can easily integrate and leverage and build rich experiences: from pure voice and text shopping assistants (SiriSparky) to customer care channels to mobile apps with rich intertwined multi-modal interaction modes ().Interested in diving inWe need solid engineers with the talent and expertise required to design build improve and evolve our capabilities in at least some of the following areas:Service oriented architecture in charge of exposing our NLU capabilities at scale and enabling increasingly sophisticated model the service takes in traffic for a large set of Walmart customers (that is 80% of American households!) you will get to solve non trivial challenges in terms of service scalability and will design and build the primitives to efficiently orchestrate model-serving microservices taking into account their dependencies and improving thecombinedlatency and robustness of such microservices (e.g. fan out in parallel to N services for a single request and reply with whichever gives the fastest answer).You will also bake-in functionality which can drive improved machine learning modeling and experimental design such as A/B serving and operationsThere is a constant tension between model improvements (more computations) and model serving latency. So we are always in a quest of crunching more numbers while preserving our SLAs and controlling the operational will guide our efforts to always find the best tradeoffs in terms of architecture tooling (Tensorflow serving / ONNYX / Triton) and infrastructure (CPU / GPU GCP / Azure) for model serving based on the latest model developments and product particular you will drive principled and scientific load-testing efforts to clearly identify the tradeoffs at hands and tune/optimize the model-serving interested you will also get some opportunity to work on prompt engineering and agentic infrastructure and pipelines for reproducible workflow and models enabling rapid innovation across the entire product will author and maintain pipelines that safely build and deploy models to production via continuous will achieve scalable and efficient resource management capabilities (cloud infrastructure).You will provide robust and built-in diagnostics for quality control will integrate or build labeling tools which can seamlessly integrate at the heart of our conversation data store (GCP Big Query) and intertwine multiple labeling sources of various confidence at the right time and you will have an enormous opportunity to make a massive impact on the design architecture and implementation of an innovative mission critical product used every day by people you know and which customers part of the emerging tech group you will also have the additional opportunity of building demos proof of concepts creating white papers writing blogs that this is not a fully remote job you are required to come to the office (currently at least 2 days a week).Minimum Qualifications6 years experience in software engineering or related data skills sound computer-science fundamentals and strong programming hands-on technical expertise in full-stack experience with at least one modern language with an efficient runtime such as Scala Java C or C#.Experience with at least one relational database technology such as My SQL Postgre SQL Oracle or MS level of fluency in Python (lingua-franca of our data-scientists).Understanding of the challenge of distributed data-processing at well with ambiguous/undefined problems; ability to think to take a project from scoping requirements through actual launch.A continuous drive to explore improve enhance automate and optimize systems and to apply scientific analysis and mathematical modeling techniques to predict measure and evaluate the consequences of designs and the ongoing success of our oral and written communication degree or certification in Computer Science Engineering Mathematics or any other related QualificationsLarge scale distributed systems experience including scalability and fault taking a leading role in building complex data-driven software systems successfully delivered to customersRelentless focus on scalability latency performance robustness and cost trade-offs especially those present in highly virtualized elastic cloud-based to cloud infrastructure such as Open Stack Azure GCP or AWS as well as infrastructure management tech (Docker Kubernetes)Experience building/operating highly available systems of data extraction ingestion and massively parallel processing for large data sets. In particular experience in building large scale data pipelines using big data technologies (e.g. Spark / Kafka / Cassandra / Hadoop / Hive / Big Query / Presto / Airflow).Hands-on expertise in many disparate technologies typically ranging from front-end user interfaces through to back-end systems and all points in with Machine Learning concepts ; processesMasters or Ph D in Computer Science Physics Engineering Math or Walmart Global TechImagine working in an environment where one line of code can make life easier for hundreds of millions of people.
