Senior Software Developer / Test Engineer - Secret

Job Description Parsons seeks a Senior Software Development Engineer in Test to design and execute test strategies spanning software‑hardware integration, sensor fusion, autonomy algorithms, and system verification in an Agile/Scrum environment. The role embeds quality practices, identifies defects early, and supports rapid iteration while meeting DoD security, safety, and performance standards in a classified defense setting. Responsibilities 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 U.S. Citizen. Active Secret clearance; willing and able to obtain/maintain TS/SCI clearance. Required Skills Bachelor’s degree in Computer Science, Software Engineering, Systems Engineering, Electrical Engineering, or related technical field and 8+ years of experience as an SDET or Test Engineer with proficiency in manual testing and 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; 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 ability to thrive in an Agile/Scrum team environment. Desired Skills 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 tools and 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. Benefits Salary Range: $103,500.00 – $181,100.00. Medical, dental, vision, paid time off, 401(k), life insurance, flexible work schedules, holidays.
