## Description

The Principal Systems Engineer 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 product to include: concept, design, fabrication, test, installation, operation, maintenance and disposal. Ensures the logical and systematic conversion of customer or product requirements into total systems solutions that acknowledge technical, schedule, and cost constraints. Performs 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 senior engineer guidance.
Essential Functions/Key Responsibilities:

 * Implements 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 document 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.
 * Implements changes to Functional/Logical/Physical Model of System Architecture and support less experienced engineers with similar tasking.
 * Supports system design, analyses, interface verification, testing, failure/anomaly resolution or mission operations.
 * Supports the testing and/or evaluation/validation of one or more components of a system or subsystem analytical model or actual system implementation.
 * Attends and prepares materials to support system engineering during major internal and external reviews.
 * 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 CONOPS development.
 * Analyzes cost history for bidders from projects where directly involved.
