Engineer III

General Atomics • Acton, MA

30d • Onsite

About The Position

General Atomics Electromagnetic Systems (GA-EMS) designs and manufactures first-of-a-kind electromagnetic and electric power generation systems. GA-EMS’ expanding portfolio of specialized products and integrated system solutions support critical fleet, space systems and satellites, missile defense, power and energy, and process and monitoring applications for defense, industrial, and commercial customers worldwide. We have an exciting opportunity in Acton, MA for a Mechanical Engineer with a focus on thermal design for optical space payloads. The ideal candidate has a strong background in heat transfer and thermal engineering and their application to space systems, direct experience in the thermal design and analysis of spacecraft or space payloads, and hands-on experience with the assembly, integration, and test (AI&T) of hardware. This role is well suited for an engineer with approximately 2–5 years of experience who is ready to take on increasing technical responsibility while working closely with experienced senior engineers. The successful applicant will work as part of a multi-disciplinary team to develop, analyze, and test thermal control solutions for optical payloads and satellite systems. You will collaborate with mechanical, systems, optical, electrical, manufacturing, and test engineers, learn and apply best practices for thermal control of space systems, and progressively assume responsibility for key portions of payload and spacecraft thermal subsystems.

Requirements

• Must be able to obtain and maintain a DoD Security Clearance.
• U.S. citizenship is required.

Nice To Haves

• Experience with thermal analysis tools such as SINDA/FLUINT and Thermal Desktop is highly desirable; experience with other thermal or finite element tools is a plus.
• Experience with the thermal design and analysis of space payloads, or other complex electro-mechanical systems; direct EO/IR space payload experience is a plus.
• Hands-on experience with the assembly, integration, and test (AI&T) of hardware, preferably including thermal control hardware (e.g., radiators, thermal straps, heaters, MLI, thermal interfaces).
• Familiarity with CAD tools (e.g., SOLIDWORKS, CREO, or NX) and basic scripting/programming (e.g., Python, MATLAB, or FORTRAN)
• Exposure to thermal vacuum (TVAC), thermal cycling, or other environmental test programs, including test planning and data analysis; experience correlating thermal models to test data is a plus.
• Demonstrated ability to apply engineering principles and perform thermal calculations, including hand calculations to support and cross-check numerical models.
• Strong written and verbal communication skills, including the ability to clearly present technical information to audiences with varying technical backgrounds.
• Ability to organize and prioritize tasks, work effectively in a team environment, and meet established deadlines or milestones.

Responsibilities

• Contribute to the design and development of thermal management solutions for optical space payloads, payload components, payload subassemblies, and orbital satellite systems.
• Perform thermal analysis, modeling, and simulation (e.g., using SINDA/FLUINT and Thermal Desktop) to support design trades, requirements verification, and performance assessments.
• Support and increasingly lead elements of the assembly, integration, and test (AI&T) process for payload thermal hardware, including procedure development, test setup, execution support, and data analysis.
• Participate in the development and review of thermal subsystem requirements, allocations, design documentation, integration plans, and test procedures.
• Support environmental test campaigns (e.g., thermal vacuum, thermal cycling), including planning, test readiness and execution, and correlation of models to test results.
• Prepare technical documentation, including analysis reports, design review materials, and test reports, for internal meetings and program milestone reviews.
• Maintain the strict confidentiality of sensitive information.
