Test Engineer Job Egg Harbor Township New Jersey USA,Software Development

Leidos is seeking a Test Engineer to join the Air Traffic Business Area within the Homeland Sector, supporting the development of the Leidos Common Automation Platform (L-CAP). L-CAP is a mission‑critical, future‑ready automation platform built on a hybrid cloud data mesh architecture, enabling next‑generation air traffic management capabilities. We are building with an AI‑first engineering mindset, embracing emerging AI capabilities and modern development practices to accelerate delivery, improve software quality, and continuously evolve how we design and build mission‑critical systems.

This role operates within a SAFe/Agile framework as part of an Agile Release Train (ART) delivering iterative value across the program. This position supports government programs and requires the ability to obtain and maintain a favorable Public Trust investigation.

This is a hybrid position requiring 3 days onsite and 2 days working from home, if you are located within a commutable distance (Less than 1 hour's drive one-way during normal traffic) from Gaithersburg, MD;
Eagan, MN; or Egg Harbor Township, NJ.

However, if you do not reside within a commutable distance, you may be considered for a 100% remote role.

What You’ll Do

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
Integrate automated tests into CI/CD pipelines ensuring continuous quality gates
Conduct performance testing to validate system behavior under load and stress conditions
Execute integration testing across platform services, APIs, and external system interfaces
Develop test plans and strategies aligned with sprint and PI objectives
Analyze defect patterns and test metrics to identify quality trends and improvement opportunities
Collaborate with development and systems engineering teams on testability and quality requirements
Support test environment configuration and test data management activities
Mentor junior test engineers on automation practices and testing methodologies
Design and execute test scenarios based on operational ATC workflows ensuring modernized services replicate legacy system behavior
Develop distributed service validation frameworks verifying inter‑service communication, data flow, and performance under operational conditions
Implement data‑driven verification approaches supporting modernization of legacy automation functions
Embrace an AI‑first engineering culture by actively adopting AI‑assisted development tools, automation, and modern engineering practices that improve productivity, code quality, and delivery velocity.
