About The Position

What you'll do... Position: Senior Software Engineer, Information Security Job Location: 1 Customer Drive, Mail Stop #0215, Bentonville, AR 72716 Duties: Tech. Problem Formulation: Translate/ co-own business problems within one's discipline to data related or mathematical solutions. Identifies appropriate methods/tools to be leveraged to provide a solution for the problem. Shares use cases and gives examples to demonstrate how the method would solve the business problem. Managing Functional Partnerships: Understand the interests & profiles of key stakeholders to manage functional relationships. Analyze stakeholder technical needs and partner with them to share relevant information. Engage with business partners on a periodic basis and establish credibility for exchanging functional information. Requirement And Scoping Analysis: Explore relevant products/solutions from an existing repertoire, that can address business/technical needs. Assess gaps/ updates/ modifications between the customer/business expectations and the existing product/solutions. Classify the requirements into applicable types. Program Monitoring: Ensure adherence to the project against approved milestones and timelines. Coding: 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. Assist in the selection of appropriate languages, development standards and tools for software coding/configuration. Take initiative to learn the fundamentals of different coding languages and frameworks that would be useful for future scope of work. Build scripts for automation of repetitive and routine tasks in CI/CD(Continuous Integration/Continuous Delivery), Testing or any other process as applicable. Implement telemetry features as required independently. Ensure security policy requirements are properly applied to components/application during code development/configuration. Testing: Map the customer requirements in to test objectives. Identify and create test cases for the component/module. Execute test cases to test the code and detect errors and defects for the entire component. Execute different types of testing using appropriate testing tools based on the testing needs Defect Management and Troubleshooting: Track and analyze defects for the component/ module and carryout regression testing to fix defects in all instances of code changes. Analyze defects from past projects/solutions to avoid recurrence of similar defects. Troubleshoot performance and availability bottlenecks for the application. DevOps Orientation: Conduct complex maintenance procedures for applications independently. Monitor and evaluate the performance of the application by tracking and analyzing appropriate metrics; Perform maintenance (corrective, adaptive, perfective) and re-engineering activities. Analyze application logs, maintenance activity data, performance data and provide analysis; Evaluate change requests to identify those which are valid and feasible. Solution Design: Assist in design of solutions such that the processes / applications work in tandem for specific components/modules of a product. Evaluate trade-offs while designing a component based on the business requirements. Assist in conversion of HLD(High Level Design) to create detailed design using mock screens, pseudo codes and detailed functional logic of the modules for specific modules / components of a product. Demonstrates up-to-date expertise and applies this to the development, execution, and improvement of action plans by providing expert advice and guidance to others in the application of information and best practices; supporting and aligning efforts to meet customer and business needs; and building commitment for perspectives and rationales.
