Position: Senior Software Engineer 

Job Location: 3155 W Wheatland Rd, Dallas, TX 75237 

Duties: Performs solution design, including software architecture; distributed systems; scalability; design patterns; disaster recovery; tech stacks; minimum viable product (MVP); non-functional requirements; and Telemetry. Assists in design of solutions such that the processes/applications work in tandem for specific components/modules of a product. Evaluates trade-offs while designing a component based on business requirements. Assists 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. Performs requirement and scoping analysis, including traceability matrix; risk analysis methodologies; cost analysis; business objectives; classification of requirements; user stories to explore relevant products/solutions from an existing repertoire to address business/technical needs. Assesses gaps/updates/modifications between the customer/business expectations and existing product/solutions (in case of agile methodology, for the iteration). Classifies the requirements into applicable types (i.e., functional/non-functional, derived/imposed/emergent, etc.). Anticipates solution risks/issues during requirements gathering phase, informs relevant stakeholders and recommends corrective steps. Contributes to the creation of user stories for component/application/complex (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. 

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 3 years of experience in software engineering or a related field.
