Northrop Grumman’s Space Sector is seeking a Systems Engineer – Level 4 to join our team in Chandler, AZ.

The Systems Engineer Level 4 will perform technical planning, system integration, verification and validation, cost and risk, and supportability and effectiveness analyses for total systems. Analyses are performed at all levels of total system products to include concept, design, fabrication, test, installation, operation, maintenance and disposal. The role ensures the logical and systematic conversion of customer or product requirements into total system solutions that acknowledge technical, schedule, and cost constraints.

Responsibilities include functional analysis, timeline analysis, detailed trade studies, requirements allocation, and interface definition studies to translate customer requirements into hardware and software specifications.

This is a hands‑on engineering position requiring strong analytical skills, a willingness to learn complex DoD requirements, and the ability to operate under more senior engineer guidance.

• Extensive requirements experience and implement and manages system requirement changes in the Requirements Management databases under direction of more experienced engineers.
• Revises and manages both original and revised specification/interface definition documents and expedites documents through signature approval process.
• Manages the requirements verification database provided to the customer, to ensure, as the system design/build matures, that it satisfies each system requirement.
• Modifies management tracking reports for a variety of systems engineering performance parameters, resource metrics and design margins.
• May also be required to support proposal‑writing efforts for Systems Engineering.
• Provides data to risk management (identifies potential risks) and trade study processes.
• Implement changes to Functional/Logical/Physical Model of System Architecture under direction and support of more experienced engineers.
• Implement System Representations under direction and support of more experienced engineers.
• Technical Resource Budgets and Configuration Control Board participation.
• Supports system design, analyses, interface verification, testing, failure/anomaly resolution or mission operations under direction of more experienced engineers.
• Implements and manages changes to system or subsystem analytical models under direction and support of more experienced engineers.
• Implements system architectures that capture the system logical/functional views and the system physical view — system elements (blocks) and critical interfaces (internal and external).
• Supports the testing and/or evaluation/validation of one or more components of a system or subsystem analytical model or actual system implementation.
• Runs existing system or subsystem analytical models and simulations to collect data while under direction and support of more experienced engineers.
• Attends and prepares materials to support system engineers during System Requirement Review, System Functional Review, Preliminary Design Review, Critical Design Review and System Verification Review.
• Supports trade studies, system sensitivity studies, design optimization studies, system performance assessments, system design assessments, Operations Analysis work such as mission analysis and timelines and Con Ops development.
• Analyzes cost history for bidders from projects where directly involved.

• Bachelor's degree in a STEM discipline (Science, Technology, Engineering or Math) with 8 years of related engineering experience; OR a Master’s degree in STEM with 6 years of related engineering experience, or a PhD in STEM with 4 years of related engineering experience.
• U.S. citizenship.
• Active U.S. DoD Interim Secret security clearance, or higher at the time of application.
• Strong written and verbal communication skills; ability to work collaboratively in team environments.

• Experience writing,…
