How much do full time mcnp jobs pay per year?

As of Jun 9, 2026, the average yearly pay for full time mcnp in the United States is $96,169.00, according to ZipRecruiter salary data. Most workers in this role earn between $81,000.00 and $109,500.00 per year, depending on experience, location, and employer.

What are Full Time MCNP jobs?

Full Time MCNP jobs involve working with the Monte Carlo N-Particle (MCNP) transport code, which is widely used for simulating nuclear processes such as neutron, photon, electron, or coupled transport. Professionals in these roles typically work in nuclear engineering, radiation shielding design, medical physics, or research institutions. Responsibilities include running simulations, analyzing results, validating models, and sometimes developing custom code or scripts to support specific projects. Full time positions often require strong backgrounds in physics, engineering, or applied mathematics, along with proficiency in MCNP and related computational tools.

What are some common challenges faced by full-time MCNP (Monte Carlo N-Particle) specialists and how can they be addressed?

Full-time MCNP specialists often encounter challenges such as managing complex simulation models, ensuring accurate input data, and interpreting intricate results. To overcome these, it's important to maintain thorough documentation, collaborate closely with subject matter experts (like nuclear engineers or physicists), and stay updated on the latest MCNP code updates and best practices. Regular peer reviews and participation in user forums or workshops can also help troubleshoot difficult modeling issues and enhance simulation accuracy.

What is the difference between Full Time Mcnp vs Full Time Paramedic?

AspectFull Time McnpFull Time Paramedic
CertificationsMcnp certification, Basic Life Support (BLS), Advanced Cardiovascular Life Support (ACLS)Paramedic certification, BLS, ACLS, and often Pre-Hospital Trauma Life Support (PHTLS)
Work EnvironmentHospitals, clinics, outpatient settingsAmbulance services, emergency scenes, pre-hospital care
Employer & IndustryHealthcare facilities, clinicsEMS agencies, emergency medical services

Both Full Time Mcnp and Full Time Paramedic roles require advanced certifications and involve patient care, but Mcnp typically works in clinical settings, while Paramedics operate mainly in pre-hospital emergency environments. The choice depends on your preferred work setting and career goals.

What are the key skills and qualifications needed to thrive as a Full-Time MCNP (Monte Carlo N-Particle) specialist, and why are they important?

To thrive as a Full-Time MCNP specialist, you need a strong background in nuclear engineering, physics, or a related field, often supported by an advanced degree and experience with radiation transport modeling. Proficiency with the MCNP software, programming languages (such as Python or Fortran), and familiarity with data analysis tools are typically required. Strong problem-solving abilities, attention to detail, and effective communication skills help individuals excel in collaborative and research-driven environments. These skills ensure accurate simulations, reliable research outcomes, and successful integration of complex modeling projects in nuclear applications.

Job description

The Aerospace Corporation is the trusted partner to the nation's space programs, solving the hardest problems and providing unmatched technical expertise. As the operator of a federally funded research and development center (FFRDC), we are broadly engaged across all aspects of space- delivering innovative solutions that span satellite, launch, ground, and cyber systems for defense, civil and commercial customers. When you join our team, you'll be part of a special collection of problem solvers, thought leaders, and innovators. Join us and take your place in space.

Job Summary

Physical Sciences Laboratories (PSL) supports the effective andtimelydevelopment and operation of national security systems through scientific research and the application of advanced technologies. PSL has more than 150 specialized laboratories used to test, analyze, and troubleshootvirtually everyaspect of rocket and satellite system design, development, construction, deployment, and operation. The diverseexpertiseof the laboratories' technical staff allows PSL to stay abreast of new technological developments and program support issues associated with rapidly evolving space systems.

The Microelectronics Technology Department (MTD) is part of PSL with specialized laboratoriesfortesting, accelerating, and analyzing, failures in electronics used for space system. MTD iscomprisedof two sections: one that performs radiation effects testing and discrete microelectronics testing, while the other section performs failure analysis on microelectronics using tools that canidentifyanomalies from the macroscopic down to the atomic scale.

MTD is looking aRadiation EffectsResearchScientist(Research Scientist/ Senior Scientist - Microelectronics/Semiconductor Engineering)to support the investigation of radiation effects, reliability- andradiation-hardness-by-design,and physics of failure of advanced CMOS, SiGe, SOI, III-V(GaN, GaAs), II-VI,and other advanced technology for space applications.
