About The Position

Leidos has an exciting opportunity for a Junior Manual Test Engineer on an important, fast-paced, mission critical program. The selected candidate will perform component, integration, and system level testing by writing and executing system-level test procedures, evaluating changes made to software applications, and verifying defect corrective actions discovered during development, testing, and/or operational use. The selected candidate will join the existing Manual Test Team in support of a fast-paced, dynamic software development program. The Manual Test team is part of a test organization that includes teams that automate tests and maintain a complex testing framework and infrastructure. The Manual Test team will drive discovery and implementation of AI concepts to improve test effectiveness and efficiency. The selected individual will utilize basic system administration skills and will work with physical equipment in a test lab environment.

Requirements

Bachelor’s degree in Computer Science, Engineering, Data Science, Statistics, or a related discipline.
Experience/familiarity with basic testing concepts (test procedures, test plans, defect tracking, regression testing, etc.).
Experience executing test cases and documenting results clearly and accurately.
Experience logging and tacking test cases and/or research findings.
Experience working with defect tracking processes/tools (create, update, validate closure).
Experience gathering and analyzing data and checking for compliance.
Basic skills with SQL or data verification (e.g., validating results in a database or log files).
Experience with programming and scripting languages (e.g., Java, shell, Python).
Experience or familiarity with using AI or other tools to identify correlations and relationships among data attributes to derive actionable insights.
Experience or familiarity with using AI or other tools to analyze relationships between key variables to identify causal factors and inform solutions.
Must demonstrate a strong attention to detail and ability to follow pre-established procedures.
Strong problem-solving skills and willingness to learn new tools and technologies.
Ability to work collaboratively in a team environment and communicate clearly with other testers and other stakeholders.

Nice To Haves

Experience in software testing, system administration, and/or quality assurance.
Experience or familiarity with Agile program environments.
Experience in using automated test tools.

Responsibilities

Perform component-level (module) system testing and progressively integrate modules to execute integration, system, and end-to-end test scenarios that validate functional behavior, interfaces, data flows, and error handling across the full solution, documenting results and coordinating defect identification, retesting, and regression checks through closure.
Accurately document test execution results and supporting evidence (including pass/fail outcomes, steps performed, test data used, and observed defects) to enable timely corrective actions, provide clear status reporting to stakeholders, and maintain traceable records that are audit-ready and can be independently reviewed to reach the same conclusion.
Execute approved test plans, procedures, and scripts to complete verification for a large, complex system, including setting up and validating test environments, running scheduled test events, capturing objective evidence and results against expected outcomes, logging anomalies/defects with sufficient detail to support troubleshooting and retesting, and using AI-enabled tools where appropriate to accelerate tasks such as test case refinement, coverage checks, result summarization, and defect triage—while ensuring a human reviews and validates outputs prior to reporting.
Develop, curate, and refine test data to support functional, integration, and regression testing, including creating representative datasets, validating data accuracy and completeness against requirements, updating datasets as the system evolves, and documenting test data sources, assumptions, and reuse procedures to ensure repeatable and reliable test execution.
Assist the Software Development, System Engineering, Integration, Deployment, and Sustainment Teams with test-related tasking when necessary.
