About The Position

What you'll do... Position: Software Engineer III Job Location: 702 S.W. 8TH ST., BENTONVILLE, AR 72716 Duties: Performs requirement and scoping analysis, including traceability matrix; risk analysis methodologies; cost analysis; business objectives; classification of requirements; user stories to understand the business/stakeholder/technical requirements and assists in analyzing the existing solutions to address the needs (in case of agile methodology, for the iteration). Prepares requirement traceability matrix and maintain traceability between business requirements, functional requirements, design, and test cases. Contributes to the creation of user stories for component/module/simple requirements (based on scalability, etc.) for Agile methodology. Reviews coding standards and guidelines; coding languages (including JavaScript, Python, C#, etc.), frameworks (including ActiveX, .Net, Cocoa, Android application framework, etc.), tools (Monday.com, Linx, Embold, etc.) and Platforms (Microsoft Azure, AWS, Apple IOS, etc.); Quality, Safety and Security (PCI, etc.) standards; utilizes emerging tools and technologies, including Telemetry, to create/configure minimalistic code for entire component/application and ensure the components are meeting business/technical requirements, non-functional requirements, low-maintainability, high-availability, and high-scalability needs. Assists in the selection of appropriate languages (JavaScript, Python, C#, etc.), development standards and tools (Monday.com, Linx, Embold, etc.) for software coding/configuration. Builds scripts for automation of repetitive and routine tasks in CI/CD (Continuous Integration/Continuous Delivery), testing or any other process (as applicable). Implements telemetry features as required independently. Ensures security policy requirements are properly applied to components/application during code development/configuration. Performs testing, including test case preparation; test objectives; test strategy; test types; test tools (Automation - Selenium, Agile - Jira, Mobile - Eggplant, etc.); test environment; root cause analysis. Maps customer requirements to test objectives. Identifies and creates test cases for the component/module. Executes test cases to test the code and detect errors and defects for the entire component. Executes different types of testing using appropriate testing tools based on the testing needs. Performs defect management and troubleshooting: defect life-cycle process, defect tracking tools and methodologies; defect reporting; regression testing; root cause analysis; and root cause corrective action. Tracks and analyzes defects for the component/ module and carries out regression testing to fix defects in all instances of code changes. Analyzes defects from past projects/solutions to avoid recurrence of similar defects. Troubleshoots performance and availability bottlenecks for the applications. Performs DevOps Orientation, including different operating systems; software maintenance tools and techniques; application monitoring tools and techniques; debugging tools; mock screen; pseudocodes; reverse engineering; traceability matrix; system performance, security, integration; data migration and accessibility; design methodologies. Conducts complex maintenance procedures for applications independently. Monitors and evaluates the performance of the application by tracking and analyzing appropriate metrics. Performs maintenance (corrective, adaptive, perfective) and re-engineering activities. Analyzes application logs, maintenance activity data, performance data and provide analysis; evaluates change requests to identify those which are valid and feasible. Conducts program monitoring including program metrics; program reporting, logging tools and processes; continuous integration/continuous deployment (CICD) to ensure adherence to the project against approved milestones and timelines. Minimum education and experience required: Bachelor’s degree or the equivalent in Computer Science, Computer Engineering, Computer Information Systems, Software Engineering, or related field plus 2 years of experience in software engineering or a related field. Skills Required: Must have experience with: Using Kubernetes to maintain and deploy containerized applications; Docker containerization for consistent deployments in different environments (Docker, Kubernetes, and AKS); Writing multistage docker builds using Debian, alpine, and ubuntu slim images for building slim images and deploying Docker containers (Docker and YAML); Writing helm charts efficiently for deploying applications using helper templates, different types of functions in helm defined by Go template language and spring template library (Helm); Maintaining OLAP databases and deploying helm charts to stateful set configuration on AKS clusters and maintaining under AKS clusters; Creating Kafka topics (Apache Kafka); Writing robust CI/CD automation pipelines for building artifacts, deploying different apps and syncing secrets from akeyless/keyvault(CI/CD, Akeyless, Key vault); Using Azure ADO, Azure repos and Git as source code repository management tools (ADO, Azure repos, Git); Building automation tools such as Maven Gradle and using Jenkins CI for automating builds and testing; Artifactory repository management tools for storing and managing artifacts; Integrating security scanning tools including SonarQube into the CI/CD pipeline for code coverage (Jenkins, Git, SonarQube, Maven, Artifactory, Key Vault, and Akeyless); Deploying java microservice based applications on AKS clusters as container pods using helm charts and updating POM files with required dependencies (Helm, AKS clusters, java microservices); Provisioning Terraform for infrastructure as code MySQL databases, provisioning Azur blob storage, and private AKS clusters using AKS modules (Terraform, MySQL, and Azure blob storage); Service mesh configuration for load balancing the incoming traffic, service-to-service authentication. Istio operator upgrades (Istio and ingress gateways); Azure and AWS services and creating the resources like Azure VMs, configuring NSGs, AKS provisioning using Terraform modules and implementing security best practices within AKS, including role-based access control (RBAC) and network policies; Prometheus and Grafana Dashboard for application telemetry monitoring and Integrated Splunk for log monitoring (Prometheus, Grafana and Splunk); Bash and shell scripting for building artifacts to install software stack on to the Azure VMs, using shell scripting for SMTP configurations on VMs (VMs, Shell scripting Linux, Unix, Bash scripting, and SMTP).
