Hypersonic Systems Engineer

Description

The Defense Group has an opening for an experienced Hypersonic Systems Engineer. Leidos is looking for experienced engineers with a Hypersonics Aerospace background to lead Systems development and Modeling and Simulation (M&S) efforts. This is a senior engineering position integrating multiple design concepts and defining analysis and test roadmaps to validate performance of hypersonic systems against system level requirements. This position will lead and develop system level critical thinking skill sets for less experienced engineers.

Responsibilities include working with hypersonic boost glide or air breathing systems, articulating technical challenges of high speed flight system design, and applying multidisciplinary knowledge across aerodynamics, aerothermal, materials, thermal, structural analysis, loads & dynamics, and related domains. Candidates should be able to define and integrate multiple domain analyses and test results through the systems engineering process from requirements generation through verification and validation, guiding methodologies and resources to meet system level requirements.

The Aerophysics group operates in a collaborative team environment where creativity is rewarded and continuous learning is the norm. Engineers in this group typically work directly with DoD personnel and interact with senior leaders in developing hypersonic weapons. This role contributes to designing the next generation of hypersonic weapon systems in a fast-growing field.

Successful candidates will interact with internal and external stakeholders to define system level requirements, plan design requirements and allocations, and develop M&S plans for execution by Leidos and external team members. They will integrate analysis and test results into a comprehensive customer deliverable that demonstrates design capabilities and ability to meet customer needs.

• Lead systems development and modeling and simulation efforts for hypersonic systems.
• Define analysis and test roadmaps to validate performance against system level requirements.
