About The Position

Leonardo DRS Naval Power Systems is seeking an experienced Systems Engineer III–IV for its Fitchburg, Massachusetts location. This role focuses on leading and executing cross-disciplinary system modeling and analysis efforts across thermal, electrical, power transmission, and control domains, with a strong emphasis on dynamic system behavior, multi-physics interactions, and integrated system performance. The position is centered on the analysis and development of complex engineered systems, supporting Model Based Systems Engineering (MBSE), requirements decomposition, and verification planning, but with a primary focus on understanding physical system interactions, using models to assess behavior, and shaping architectures for robust, high-performing solutions. This role is ideal for a systems engineer with strong fundamentals in thermo-fluid systems, electrical power systems, controls, energy conversion, transmission systems, and dynamic cycles, who can collaborate across organizational and multi-disciplinary boundaries to develop practical, analyzable system solutions.

Requirements

Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Electrical Engineering, Systems Engineering, or a related engineering discipline.
5+ years of relevant engineering experience for Level III consideration; additional experience and demonstrated technical breadth for Level IV consideration.
Experience analyzing and modeling complex systems that span multiple disciplines such as thermal/fluid, electrical, controls, mechanical, or power systems.
Demonstrated ability to perform first-principles engineering analysis and translate findings into practical system architecture or design recommendations.
Experience with dynamic system modeling, transient analysis, or simulation of integrated physical systems.
Working knowledge of energy conversion systems, power generation systems, fluid systems, thermal systems, electrical systems, or control systems.
Ability to decompose complex technical problems, define analytical approaches, and communicate conclusions clearly to multidisciplinary teams.
Experience supporting system integration, trade studies, or performance assessment for complex engineered products.
U.S. Citizenship required.
This position requires an active DOD security clearance or the ability to obtain such clearance within a reasonable time after commencement of employment.

Nice To Haves

Experience with shipboard, naval, industrial, or other large integrated power and energy systems.
Knowledge of Rankine, Brayton, or other open- and closed-cycle systems.
Experience with thermo-fluid system analysis including piping, heat exchangers, pumps, flow networks, and heat balance methods.
Experience with control-oriented system modeling, dynamic response analysis, system tuning, hardware-in-the-loop concepts, or commissioning support.
Familiarity with electrical power generation, regulation, conversion, protection, or transmission systems.
Experience using system simulation and modeling tools such as Simulink, Simcenter, AxSTREAM/AxCYCLE, Modelica-based tools, or comparable multi-physics environments.
Familiarity with optimization, multivariate analysis, uncertainty analysis, or design space exploration methods.
Exposure to defense, marine, propulsion, turbine-generator, or Navy-related applications.
Familiarity with MBSE tools and methods, including SysML, used as a supporting systems engineering framework.

Responsibilities

Perform system-level modeling, analysis, and trade studies across multiple physical domains, with emphasis on dynamic and transient behavior.
Develop and evaluate integrated system architectures involving combinations of thermal, electrical, mechanical, controls, power conversion, and transmission elements.
Analyze system interactions, interfaces, and performance margins to ensure components function together as a cohesive and reliable system.
Build, adapt, and apply lumped-parameter, reduced-order, and multi-physics models to support design decisions, performance predictions, and risk reduction.
Support the development of system concepts, operating philosophies, and functional behavior for complex power and energy systems.
Perform engineering analyses related to system cycles, energy balances, heat transfer, fluid flow, control response, power distribution, and component interaction.
Lead or support design studies involving integrated plant and subsystem performance, including normal operation, off-design conditions, and transient events.
Define and assess system requirements derived from analysis, operational expectations, interfaces, and performance objectives.
Support verification and validation planning by linking analytical methods, simulation results, and test approaches to system requirements.
Collaborate with component, controls, electrical, mechanical, and test engineers to mature integrated solutions.
Interface with internal subject matter experts, suppliers, and program stakeholders to coordinate technical inputs into coherent system designs.
Contribute to MBSE, requirements management, systems integration, and systems Verification & Validation (V&V) activities as collateral duties in support of the broader engineering lifecycle.
