Integration Software Engineer Jobs (NOW HIRING)

ASRC Federal Mission Solutions is a premier provider of systems engineering, software engineering, system integration and project management services for real-time, mission-critical defense systems.

We are seeking a Software Integration & Test Engineer in support of the development and sustainment of the U.S. Navy Aegis Weapons System in Moorestown, NJ. The Software Integration & Test Engineer supports system-level software integration within a laboratory environment.  This role executes requirement-driven manual and automated integration testing, supports software loading and lab operations, and performs troubleshooting across distributed software components and pub/sub architectures. The position requires hands-on engagement with live systems, gray-box analysis of production code, and development of integration support tools in a configuration-controlled environment.

Roles and Responsibilities:

• Develop working-level understanding of system architecture and inter-subsystem message flows in distributed pub/sub environments.
• Read and analyze production software code when required to support integration troubleshooting, gray-box validation, and development of requirement-aligned test procedures.
• Develop and execute system-level integration test procedures derived from documented software requirements, in parallel with or prior to software implementation, and document test outcomes.
• Identify, isolate, reproduce, document, and retest integration defects; capture logs, traces, and diagnostic data to support root cause analysis.
• Develop, maintain, and execute automated regression tests using Python; analyze failures to determine root cause (software, environment, or automation).
• Develop small utilities, scripts, or integration support tools to enhance testing, automation, and diagnostic capabilities.
• Install, configure, load, and integrate subsystem software builds into laboratory equipment suites; execute integration testing using hardware, simulators, and networked systems.
• Maintain laboratory system operability and equipment readiness, providing hands-on operational and technical support during integration and test activities, leveraging expertise in lab equipment and system behavior.
• Plan, schedule, and coordinate laboratory resource usage to enable effective integration and test execution.
• Collaborate effectively with software developers, systems engineers, and integration teams in a configuration-controlled environment.
• Support integration events and testing activities outside standard business hours as required.

Requirements:

• Bachelor’s degree in Computer Science, Engineering, or related technical discipline.
• This position requires the ability to obtain and maintain a government clearance, U.S. Citizenship is required.
• This position requires the successful applicant to obtain and maintain the required security clearance or other authorization(s) within the necessary timeframe required by applicable contract(s).
• 2–4 years of experience in software integration, system test, or software engineering in a structured, configuration-controlled environment.
• Ability to work on-site in laboratory environments and support testing outside standard business hours.
• Experience executing system-level test procedures derived from documented requirements.
• Experience troubleshooting distributed software systems in Linux/Unix environments.
• Ability to read and analyze production software code written in C/C++, Java, or similar languages to support integration troubleshooting and gray-box validation.
• Proficiency in Python or comparable scripting language.
• Experience capturing and analyzing logs, traces, and diagnostic data to support root cause analysis.
• Strong written and verbal communication skills.

Preferred but Not Required Experience:

• Experience integrating software in distributed or system-of-systems architectures.
• Familiarity with pub/sub messaging systems and message-based communication patterns.
• Experience developing automated test frameworks or integration support tooling.
• Familiarity with CI/CD pipelines and automated build/test environments.
• Experience using version control, artifact management, and issue/requirements tracking tools (e.g., Git, Artifactory, Jira, DOORS, Jazz, or similar).
• Exposure to performance analysis, performance metrics collection, or system resource monitoring tools.
• Industry-recognized certifications related to software testing, quality engineering, cybersecurity, or software development (e.g., ISTQB, Security+, or similar).
