Lead Test Engineer
About The Position
Leidos is seeking a Test Engineer to support development of the Leidos Common Automation Platform (L-CAP) within the Air Traffic Business Area of the Homeland Sector. L-CAP is a mission-critical automation platform built on a hybrid cloud data mesh architecture to enable next-generation air traffic management capabilities. The team uses an AI-first engineering mindset and modern development practices to improve delivery and software quality. The role operates within a SAFe/Agile framework as part of an Agile Release Train delivering iterative value across the program. It supports government programs and requires the ability to obtain and maintain a favorable Public Trust investigation. This is a hybrid position for candidates within a commutable distance (less than one hour's drive one-way during normal traffic) of Gaithersburg, Maryland; Eagan, Minnesota; or Egg Harbor Township, New Jersey, with three days onsite and two days working from home. Candidates who do not reside within a commutable distance may be considered for a 100% remote role.
Requirements
- Bachelor’s degree in Computer Science, Software Engineering, or a related discipline with 8 or more years of experience, or a master’s degree with 6 or more years of experience; additional experience, education, and training may be considered in lieu of a degree.
- Strong experience with test automation frameworks such as Selenium, JUnit, pytest, or equivalent, and Java or JavaScript test development.
- Expertise integrating automated testing into CI/CD pipelines using Jenkins, GitLab CI, GitHub Actions, or similar tools.
- High experience with performance, integration, and API testing for distributed systems using tools such as JMeter or Gatling.
- Knowledge of distributed service testing, including service virtualization, contract testing, chaos engineering, and data-driven test automation.
- Experience with operational scenario-based testing, behavioral validation, root cause analysis, and defect investigation.
- Familiarity with Agile/SAFe testing, quality engineering principles, test management, and defect tracking tools.
- Ability to obtain and maintain a Public Trust.
- U.S. citizenship is required.
- Successful completion of background investigations as required by the government customer.
Nice To Haves
- Python scripting and test development proficiency.
- Experience testing microservices and event-driven architectures.
- Knowledge of containerized test environments such as Docker and Kubernetes.
- Experience with API testing frameworks such as REST Assured and Postman/Newman.
- Familiarity with security testing tools and practices.
- Experience in aviation, defense, or safety-critical testing domains.
- Knowledge of test-driven development (TDD) and behavior-driven development (BDD).
- Experience with AI-assisted development tools, such as code generation, automated testing, and intelligent debugging.
- Experience testing legacy-to-modern migration and verifying functional equivalence between old and new systems.
Responsibilities
- Design and implement test automation frameworks for microservices-based platform components.
- Build and maintain reusable test libraries and utilities for the L-CAP test infrastructure.
