ECSE - Senior Mechanical Engineer

Mission Support and Test Services, LLC (MSTS) manages and operates the Nevada National Security Site (NNSS) for the U.S. National Nuclear Security Administration (NNSA).  Our MISSION is to help ensure the security of the United States and its allies by providing high-hazard experimentation and incident response capabilities through operations, engineering, education, field, and integration services and by acting as environmental stewards to the Site’s Cold War legacy.  Our VISION is to be the user site of choice for large-scale, high-hazard, national security experimentation, with premier facilities and capabilities below ground, on the ground, and in the air. (See NNSS.gov for our unique capabilities.) Our 2,750+ professional, craft, and support employees are called upon to innovate, collaborate, and deliver on some of the more difficult nuclear security challenges facing the world today.   

• MSTS offers our full-time employees highly competitive salaries and benefits packages including medical, dental, and vision; both a pension and a 401k; paid time off and 96 hours of paid holidays; relocation (if located more than 75 miles from work location); tuition assistance and reimbursement; and more.  
• MSTS is a limited liability company consisting of Honeywell International Inc. (Honeywell), Jacobs Engineering Group Inc. (Jacobs), and HII Nuclear Inc.

The Nevada National Security Sites (NNSS) is seeking an outstanding Staff Engineer supporting the Advanced Sources and Detectors (ASD) Project as part of the Scorpius Accelerator Group. ASD is responsible for developing the world’s newest and most advanced Linear Induction Accelerator (Scorpius) where it will generate high-current, relativistic electron beams that will be converted into intense bremsstrahlung x-ray pulses used to interrogate dynamic materials.

In this role, you will be expected to apply a range of theoretical, computational, and experimental techniques. Experience with large pulsed power equipment and systems (linear induction accelerators, pulsed diodes, high power lasers, Z-pinch machines, high magnetic fields, etc.) is preferred.

Key Responsibilities

• Serve as a key member of ASD Technology Maturation and Design teams to address mechanical designs related to Scorpius accelerator mechanical engineering systems.
• Help plan and conduct work-requiring judgment in the evaluation, selection, application, and modification of mechanical parts and assemblies.
• Implement new approaches for designing and drafting complex chassis builds and mechanical assemblies.
• Plan, guide, or prepare administrative and technical documents as required for the design and build of complex assemblies.
• Apply creative solutions to produce 3D CAD designs of Scorpius accelerator systems, structures, and components.
• Produce high-quality engineering assembly and component manufacturing drawings to ASME Y14.5 standards.
• Research, analyze, design, test, and verify engineering and technology solutions.
• Plan, schedule, and coordinate the preparation of activities or documents related to the project.
• Support research and development, and technology maturation activities in laboratory testing environments.
• Adapt to evolving R&D design requirements while meeting safety, security, compliance, and schedule imperatives.
• Ability to work under limited technical direction exercising Engineering judgement.
• Advises senior team members on technology utilization and development.
• May be invited to serve on internal and external committees.

• Bachelor’s degree in an engineering program accredited by the Accreditation Board for Engineering and Technology (ABET) required for Civil, Mechanical and Electrical engineering degrees

  • Or, Calculus-based STEM bachelor’s degree in engineering

     

  • Or Professional Engineer license
• Plus at least 5 years’ relevant experience. Skill building experience must demonstrate either deeper technical specialization or additional cross-disciplinary knowledge; graduate research experience may be recognized.
• Knowledge of how codes and standards of other disciplines affect their discipline.
• Demonstrated experience in precision mechanical design of structures, systems, and components, with due consideration to design for manufacturability.
• Demonstrated knowledge and implementation of various fabrication processes including metals machining, welding, and metal forming.
• Demonstrated experience working within a formal design process environment, including supporting engineering change orders and approvals.
• Demonstrated experience interfacing with machine shops and machine shop operations and resolving manufacturing issues with fabricators.
• Excellent interpersonal, verbal,
