Job Description:
Parsons is looking for an exceptionally talented Senior Software Development Engineer in Test to join our team! In this role, you will design and execute test strategies that span software-hardware integration, sensor fusion, autonomy algorithms, and end-to-end system verification within a fast-paced Agile/Scrum environment. You will embed quality practices, identify defects early, and support rapid iteration while meeting stringent DoD security, safety, and performance standards in a classified defense setting.
What You'll Be Doing:
Develop, maintain, and execute detailed test plans, test cases, and test procedures for software-hardware integration, interface validation, sensor data handling, and autonomy module performance
Perform manual exploratory, functional, regression, and system-level testing in integration labs and hardware-in-the-loop (HWIL) environments
Design, implement, and maintain automated test frameworks and scripts (UI, API, integration, and performance) to accelerate verification within CI/CD and MLOps pipelines
Collaborate with software developers, systems engineers, and the Scrum Master to define acceptance criteria, automate regression suites, and shift quality left in every sprint
Conduct integration & verification (I&V) activities, including defect triage, root-cause analysis, and verification of MOSA compliance and interoperability requirements
Integrate automated tests into DevSecOps pipelines (static/dynamic analysis, container scanning, and model validation) to ensure secure, repeatable deployments
Support formal qualification testing, field demonstrations, and operational assessments for USSOCOM unmanned platforms
Document test artifacts in tools such as Jira, Confluence, and test management systems while maintaining traceability to program requirements
Identify process improvements, champion test automation best practices, and mentor junior testers on manual and automated techniques
Work in compliance with DoD, USSOCOM, and program security requirements while sustaining high Agile velocity in a high-tempo, sometimes classified development environment
Required Clearance:
Must be a U.S. Citizen
Must possess an active Secret clearance and be willing/able to obtain/maintain a TS/SCI clearance
What Required Skills You'll Bring:
Bachelor's degree in Computer Science, Software Engineering, Systems Engineering, Electrical Engineering, or a related technical field and 8+ years of hands-on experience as a Software Development Engineer in Test (SDET) or Test Engineer, with demonstrated proficiency in both manual testing and test automation
Strong manual testing skills, including test design, exploratory testing, and execution in complex software-hardware integration environments
Solid experience developing and maintaining automated tests using frameworks such as Selenium, PyTest, Robot Framework, Cucumber, or equivalent, with scripting proficiency in Python or similar languages
Working knowledge of CI/CD pipelines (GitLab CI, Jenkins), containerization (Docker, Kubernetes), and test integration within DevSecOps workflows
Understanding of systems engineering principles, interface management, and integration & verification processes
Willingness to travel (25-50%)
Excellent collaboration, communication, and problem-solving skills with the ability to thrive in an Agile/Scrum team environment
What Desired Skills You'll Bring:
Experience supporting DoD or USSOCOM programs, especially in unmanned systems, autonomy, AI/ML, or MOSA-based architectures.
Hands-on background with defense-specific testing environments (integration labs, HWIL, autonomy simulation frameworks, or sensor test beds).
Prior exposure to classified development workflows and cross-domain solutions.
Certifications such as ISTQB, Certified Tester, or equivalent Agile testing credentials.
Preferred Toolsets / Technologies: Python, Java, Selenium, Playwright, Cypress, Postman, Docker, Kubernetes, GitLab, Jenkins, Terraform, OpenShift, REST APIs, Kafka, Elasticsearch, Grafana, Jira, Confluence, TAK Ecosystem Technologies, AI/ML Frameworks, Linux, AWS, Azure
