Software Engineer - Java/Cloud

Redolent•Sunnyvale, CA

5d•Hybrid

About The Position

This role involves building highly scalable, fault-tolerant, and reactive Microservices using Java/Scala, AKKA, and RESTful architecture for Walmart Omni platforms. The engineer will design and develop applications using No-SQL databases such as Cassandra, ScyllaDB, YugaByteDB, and Azure Cosmos DB for the Walmart e-commerce platform, leveraging open-source technologies like Akka-Http, Apache Camel, Apache Drools, and Rest/Grpc Webservices. A key responsibility is to work with the application team to migrate from virtual machines to containers using Kubernetes and CI/CD, and to optimize platform utilization. The role requires experience deploying web applications to cloud infrastructure (Azure, GCP) and working with distributed, service-oriented architectures, with a focus on continuously improving DevOps tooling and software delivery processes. The engineer will also research application components to enhance product scalability, stability, and performance, build high-throughput data pipelines using Apache Kafka for Azure/GCP Data Lake, and lead the migration of legacy catalog services to next-generation reactive microsystems deployed in Kubernetes on public cloud platforms (GCP, Azure). Understanding the machine learning lifecycle and building solutions for data scientists to iterate and deploy ML applications at scale is also part of the role. Additionally, the engineer will develop applications for web and mobile media, utilize data structure and algorithmic skills for data mining, and apply industry research and innovation to build next-generation systems. The role includes designing and developing service-oriented (SOA) architectures and Big Data platforms using Hortonworks, Cloudera CDH, Apache Hadoop, Apache Spark, and Presto Analytics Engine. Directing root cause analysis of critical issues and designing/architecting cloud-native, distributed, high-performance, and scalable microservices for the Walmart grocery ecosystem are also key duties. Collaboration with geographically distributed teams for development, rollout of new features, and issue resolution is expected.
