Job Title:

Mechanical EngineerJob Description This role offers the opportunity to work as a Mechanical Engineer within a highly innovative team that develops cutting-edge security and space-based solutions for government customers. You will design, analyze, and support first-of-a-kind electromagnetic and electric power generation systems, spacecraft payloads, and satellite structures, often in highly constrained, power-limited environments. The position involves tackling complex, non-traditional engineering challenges in the national security arena while collaborating with multidisciplinary teams focused on spacecraft systems, ground control, embedded software, and unique cyber capabilities. Responsibilities

+ Independently perform difficult and complex mechanical engineering work with guidance focused on overall objectives and expected results.

+ Develop, document, and present technical findings, ensuring clear communication of results to engineering staff and stakeholders.

+ Serve as a primary technical point of contact on small contracts or single component projects, representing the organization in technical discussions as needed.

+ Support the operation of engineering systems, identify issues, and document problems and resolutions thoroughly.

+ Devise new approaches and methodologies to resolve unusual or complex engineering problems in spacecraft and related systems.

+ Troubleshoot conflicting design and development requirements, including challenging coordination and special material requirements.

+ Prepare high-quality technical documentation and deliver formal technical presentations to internal and external audiences.

+ Provide direction and technical guidance to design and technical staff, and lead a team of moderately experienced professional engineers when required.

+ Maintain strict confidentiality of sensitive and classified information while working on national security-related programs.

+ Observe and comply with all applicable laws, regulations, and organizational obligations in the performance of engineering work.

+ Work safely and consistently follow established operating procedures, engineering standards, and best practices.

+ Collaborate with multidisciplinary teams involved in spacecraft payloads, satellite systems, ground control, embedded software, and cyber capabilities.

+ Contribute to the structural and thermal design, analysis, and testing of metallic and composite spacecraft structures, where applicable.

+ Support or participate in hardware spacecraft testing, including environmental testing and verification of test requirements, when needed.

+ Perform other related engineering duties as assigned to support program and organizational objectives. Essential Skills

+ Bachelors degree, masters degree, or PhD in engineering or a related technical discipline from an accredited institution, or equivalent engineering experience in lieu of formal education.

+ Progressive engineering experience typically including six or more years with a bachelors degree, four or more years with a masters degree, or two or more years with a PhD.

+ Previous experience with satellite space systems.

+ Experience with computer-aided design (CAD) and/or finite element analysis (FEA) software such as SolidWorks, NASTRAN, or ANSYS.

+ Thorough understanding of core engineering concepts, principles, codes, and theory, with demonstrated broad application of those concepts.

+ Ability to develop and communicate new engineering concepts and apply them accurately in evolving technical environments.

+ Ability to organize, schedule, and coordinate work phases and determine appropriate approaches at the task level, and with support, at the project level, to solve complex problems.

+ Strong technical communication skills, including the ability to document work clearly and deliver effective technical presentations.

+ Ability to maintain confidentiality and handle sensitive information appropriately.

+ Commitment to safe work practices and adherence to established operating procedures. Additional Skills & Qualifications

+ Experience with structural analysis of metallic and composite spacecraft structures.

+ Experience in hardware spacecraft testing, environmental testing, and development or interpretation of test requirements.

+ Demonstrated proficiency in thermal modeling and simulation tools for space applications, such as Thermal Desktop.

+ Solid understanding of heat transfer principles, thermal management techniques, and selection of materials suitable for space environments.

+ Knowledge of propulsion system design and experience with the development and testing of cold gas propulsion systems.

+ Familiarity with the full satellite system design life cycle, including spacecraft-level environmental testing, launch, and on-orbit operations.

+ Expanding knowledge of principles, concepts, theory, and practices in related technical specialties beyond core mechanical engineering.

+ Experience working in multidisciplinary teams that include spacecraft payload, system development, ground control, embedded software, and cyber capabilities.

+ Interest in working on innovative, non-traditional solutions to challenging national security problems. Work Environment This position is based onsite at a smaller, highly focused business unit, providing a close-knit environment where you will not feel like just another cog in the wheel.
