You will help ensure mission-essential applications function as intended, deliver accurate information, and perform reliably when our customers need them most. As an integral member of a collaborative Agile development team, you will take a hands-on approach to software quality through manual functional testing, comprehensive test planning, detailed test procedure development, and API validation. Responsibilities: - Plan, develop, and execute comprehensive manual test cases and detailed test procedures to validate software functionality against defined requirements, user stories, and acceptance criteria. - Perform hands-on functional, integration, system, regression, smoke, and exploratory testing of web-based applications and associated services. - Develop and maintain test plans, test scenarios, test cases, test procedures, and test execution documentation that provide clear, repeatable, and traceable verification of software requirements. - Conduct API testing using tools such as Bruno, Postman, and/or Swagger UI to validate RESTful services, HTTP requests and responses, JSON payloads, authentication, error handling, and data integrity. - Collaborate with developers, product owners, business analysts, and other stakeholders to understand application functionality, clarify requirements, and identify appropriate testing strategies. - Participate actively in Agile ceremonies, including sprint planning, daily standups, backlog refinement, sprint reviews, and retrospectives. - Analyze user stories and acceptance criteria to identify positive, negative, boundary, and edge-case test scenarios. - Execute manual tests across development, integration, and staging environments to identify functional defects, integration issues, and unexpected application behavior. - Document, track, and manage software defects using Jira or comparable issue-tracking tools, providing clear reproduction steps, supporting evidence, and expected versus actual results. - Perform defect verification and regression testing to confirm that identified issues have been resolved without introducing new problems. - Maintain requirements traceability to ensure test coverage aligns with functional specifications and customer expectations. - Support test data preparation, test environment readiness, and troubleshooting activities to enable effective test execution. - Work closely with software engineers to investigate application issues, isolate defects, and support root-cause analysis. - Communicate testing progress, defect trends, risks, and overall software quality to Agile team members and program stakeholders. - Identify opportunities to improve testing processes, increase test coverage, and strengthen overall software quality throughout the development lifecycle. Requirements: - Bachelor's degree in Computer Science, Engineering, Information Technology or related field and 4-8 years of prior relevant experience or Master's with 2-6 years of prior relevant experience. - 4+ years of software testing, quality engineering, or software validation experience. - Demonstrated experience performing manual functional, integration, regression, and system testing of enterprise software applications. - Proven ability to develop comprehensive test plans, detailed test procedures, test cases, and test scenarios based on software requirements and user stories. - Hands-on experience performing API testing using Bruno, Postman, or comparable API testing tools. - Working knowledge of RESTful APIs, HTTP methods, status codes, JSON payloads, and API request/response validation. - Experience identifying, documenting, tracking, and retesting software defects. - Experience working within an Agile software development environment, including participation in Scrum ceremonies and sprint-based testing activities. - Experience using test management and issue-tracking tools such as Jira, or equivalent platforms. - Strong understanding of software testing methodologies, the Agile Software Development Life Cycle (Agile SDLC) the software development lifecycle (SDLC), and the software testing lifecycle (STLC). - Ability to analyze technical requirements and translate them into clear, measurable, and repeatable test procedures. - Experience validating end-to-end business processes and user workflows across multiple application components. - Hands-on experience with geospatial applications or GEOINT data. - Strong analytical, troubleshooting, and problem-solving skills with exceptional attention to detail. - Excellent written and verbal communication skills, including the ability to clearly document test results and communicate defects to technical and nontechnical stakeholders. - Ability to work independently and collaboratively in a fast-paced, mission-focused Agile environment. Preferred Qualifications: - Experience supporting DoD or IC programs. - Experience developing and executing detailed test procedures for complex, mission-critical enterprise applications. - Experience testing applications that support intelligence analysis, data processing, or operational workflows. - Familiarity with API authentication mechanisms, including OAuth 2.0, JWT, and role-based access controls. - Experience performing SQL queries to validate backend data, troubleshoot defects, and verify data integrity. - Experience testing microservices-based applications and distributed systems. - Familiarity with Continuous Integration/Continuous Delivery (CI/CD) processes and DevSecOps software delivery practices. - Exposure to automated testing frameworks or tools such as Playwright, Selenium, or Cypress. - Experience testing cloud-hosted applications or applications deployed in AWS environments. - Familiarity with Linux environments, command-line utilities, and application log analysis. - Experience with requirements traceability matrices, formal test documentation, and test readiness reviews. - Knowledge of accessibility, usability, and security testing considerations. - Experience working with cross-functional teams to improve testing processes and establish quality engineering best practices. - Certifications such as ISTQB, CASTP, CAST, CSTE, Security+, or similar. ## Skills ### Required - Agile - API testing - Bruno - Postman - Swagger UI - RESTful APIs - HTTP methods - JSON payloads - API request/response validation - Jira - software testing methodologies - Agile SDLC - SDLC - STLC ### Nice to have - DoD or IC programs - detailed test procedures - intelligence analysis - data processing - operational workflows - OAuth 2.0 - JWT - role-based access controls - SQL queries - microservices-based applications - distributed systems - CI/CD processes - DevSecOps - automated testing frameworks - Playwright - Selenium - Cypress - AWS environments - Linux environments - requirements traceability matrices - formal test documentation - test readiness reviews --- Source: [Apply at leidos.wd5.myworkdayjobs.com](https://leidos.wd5.myworkdayjobs.com/en-US/External/job/Gaithersburg-MD/Mid-Level-Test-Engineer_R-00194560?utm_source=yubhub.co&utm_medium=jobs_feed&utm_campaign=apply)
