Initiative, creativity, reliability, and efficient teamwork will be required to successfully deliver innovative solutions in this dynamic customer space.

The selected Senior Systems Architect will be responsible to turn customer’s goals and needs into solutions. The Systems Engineer possesses the background and skills to communicate both with customers and IDT designers, lead development and deployment teams, and define product features and capabilities to apply automated Testing and Analysis technologies for rapid assessment and deployment of capability.

The ideal candidate will have skills applicable to instrumentation and data recording, data analysis, behavior assessment against requirements, understanding of Combat Systems, Kill Chains and/or effects chains, and presentation/visualization methods to help the System Analyst understand results and take corrective actions. The candidate will learn IDT’s technologies and how to apply them to a Customer’s Products to accelerate the pace of development, test, deployment, and in-service upgrade.
All applicants must be able to obtain/maintain an active Secret U.S. Security Clearance.
This is an on-site position. Requiring at least 4 days in the office, based out of our Arlington, VA or Mount Laurel, NJ location.

What You Will Do:
Develop test/data algorithms for reducing instrumentation and data streams to meaningful quantification of system actions, behaviors, and outcomes
Evaluate customer/operational needs to define system performance requirements, integrate technical parameters and assure compatibility of all functional and program interfaces
Apply advanced systems/software technologies and principles to develop innovative solutions for in-service and next generation complex software systems
Drive interdisciplinary teams to rapidly define, design, develop, integrate, and deploy tactical and test systems
Analyze and decompose requirements, review software designs, generate test cases, test procedures, and test plans, and troubleshoot discrepancies to fulfill customer needs
Perform analyses to optimize total system of systems and/or system architecture
Determine operational feasibility by evaluating analysis, problem definition, requirements, solution development, and proposed solutions
Determine SysML model implementation of Systems Engineering designs
Communicate directly with customer and users to understand need and drive cross-functional technical issues/challenges to closure

Who You Are (Required):
Bachelor’s Degree in engineering, computer science, mathematics, physics, other STEM field, or equivalent full-time professional experience
7-10+ Years experience in building, testing and fielding products
Ability and interest in the logical, systematic conversion of program requirements into viable technical solutions
Mathematical and communication skills to understand what System Users and Testers need to make decisions and do assessments rapidly and accurately
Understanding of System Engineering and Software Engineering best practices. Ability to communicate with customer Subject Matter Experts and understand their processes and designs.
Understanding of performing test and integration, applying best engineering practices, and developing test methodologies
Ability to apply analysis to systems, data, and processes to determine if exhibited Behavior is expected
Ability to understand system behavior through reading system specifications and requirements
Understanding of the activities described by the Systems Engineering V-Model
Ability to work on-site with potential hybrid flexibility
Ability to travel approximately 10%
What Makes You Stand Out:
Knowledge of modern AESA or DBF radar designs, distributed Kill Chains and Combat System, and management of distributed data for decision making
Ability to create Agentic AI workflows to accelerate turning data into decisions, accelerate system design, and facilitate rapid trade studies and product decisions
Familiarity with Model Based Systems Engineering/Model Based Software Development using SysML or UML
Demonstrated knowledge in related disciplines (e.g. Software Engineering)
Familiarity with Agile development processes
Experience developing or testing large, complex systems
Experience implementing algorithms in C++, Python, MATLAB or other languages
Systems Engineering experience with system integration, verification, and validation testing
Experience designing and testing complex SW systems, especially DoD Systems or large distributed SW Solutions
Experience performing test and integration, applying best engineering practices, and developing test methodologies
Experience with data visualization and presentation. Understanding of data instrumentation and data reduction techniques to use data to communicate system performance
Experience and proficiency with Requirements Management tools (e.g. DOORS)
Experience identifying and describing software interfaces
Ability to perform concurrent assignments and adapt to changing priorities
Excellent verbal and written communication skills
Strong Team-centric execution and coordination skills
