What are the different positions in NASA?

The work done at the National Aeronautics and Space Administration spans vastly more territory than just strapping humans onto rockets; it involves intricate science, massive logistical undertakings, complex technology development, and essential administrative support. When people think of NASA jobs, the image is often that of an astronaut floating in space or a rocket scientist in a clean room. While those positions are certainly present, the organization requires thousands of different specialties to achieve its goals, from the Martian rover teams to the teams managing international agreements. ^[1][2] Understanding the breadth of these careers reveals an ecosystem of expertise required to push the boundaries of human knowledge and exploration.

# Application Gateway

For most entry points into the agency, the process follows standard federal hiring procedures. Unlike private aerospace companies, a significant portion of NASA positions are posted through the official U.S. government employment website, USAJOBS. ^[7] This is the central hub where applicants will find postings for civil service positions across the various NASA centers. ^[1][7]

It is important for prospective employees to recognize that the application process isn't simply uploading a resume; it requires tailoring application materials to meet specific federal vacancy announcement requirements. ^[7] Furthermore, jobs at specific centers, like the Jet Propulsion Laboratory (JPL), which is managed by Caltech for NASA, may utilize their own dedicated application portals alongside or instead of the main federal site. ^[5]

A crucial, though often overlooked, aspect of navigating these federal listings is understanding the grading system. Positions are frequently classified using the General Schedule (GS) pay scale. ^[7] For someone transitioning from industry, grasping where a role falls on the GS-11 or GS-15 scale provides immediate context about the expected level of responsibility, required experience, and salary band, something not always immediately obvious from a broad job title alone. ^[7] Success in applying often hinges on translating one's private-sector experience into the specific language and competencies demanded by these federal job descriptions.

# Engineering Core

Engineers form the backbone of the hardware and software that make space exploration possible. These roles are essential for designing, building, testing, and operating everything from launch vehicles and habitats to sophisticated scientific instruments. ^[2][4] The sheer variety within this category is immense.

# System Development

Roles such as aerospace engineers, mechanical engineers, and electrical engineers are fundamental. Aerospace engineers focus on the dynamics of flight, propulsion systems, and vehicle design. ^[2][4] Mechanical engineers tackle structural integrity, thermal control, and moving parts—the things that must physically survive launch and the extreme environments of space. Electrical engineers deal with power systems, avionics, and communication arrays. ^[2] These positions are heavily concentrated at centers with major development facilities, like Kennedy Space Center or Johnson Space Center.

# Software and Computing

With every mission relying on immense data processing, telemetry, and autonomous operations, Information Technology (IT) professionals and software developers are indispensable. ^[2] This group encompasses cybersecurity specialists protecting sensitive data, network engineers maintaining global communications, and software engineers coding the flight control systems or the algorithms that process images from the James Webb Space Telescope. At centers like JPL, which specializes heavily in robotic exploration, mission software development is often the largest single engineering discipline. ^[5]

# Scientific Discovery

NASA’s fundamental purpose is to explore and discover, meaning scientific positions are central to its mission. These roles often require advanced academic degrees and focus on analyzing data and proposing new areas of inquiry. ^[3][4]

# Domain Expertise

Scientists fall into numerous fields, often aligned with NASA’s core research areas: planetary science, astrophysics, Earth science, and heliophysics. ^[3][4]

• Astrophysicists and Planetary Scientists: These individuals study celestial bodies, stellar evolution, and the origins of the universe, directly interpreting data returned by probes and telescopes. ^[4]
• Earth Scientists: These professionals apply space-based observation technology to study terrestrial systems—climate change, weather patterns, ocean currents, and land use—using NASA’s fleet of Earth-observing satellites. ^[3]

A key difference to note in the scientific track is the division between civil servant scientists (federal employees) and researchers working at affiliated institutions (like universities or Federally Funded Research and Development Centers like JPL). ^[4][5] While both groups collaborate intensely, their employment structures and day-to-day focus can differ; the civil servant often focuses on direct agency programs, whereas the affiliated researcher might have more freedom to pursue fundamental, curiosity-driven research, though both feed into NASA’s strategic goals. ^[4]

# Astronaut Corps

The most visible positions at NASA are, without question, the astronauts. These roles are extremely selective, requiring backgrounds in science, technology, engineering, or mathematics (STEM), or extensive piloting experience. ^[3] However, even within the Astronaut Office, there is a defined hierarchy, far beyond simply being an "astronaut". ^[6]

# Astronaut Ranks and Roles

Astronauts progress through defined ranks based on experience and tenure, a structure mirroring traditional military or naval organizations. ^[6]

The hierarchy ensures that the most experienced individuals, often those who have flown multiple missions, assume leadership roles in training the next generation and in critical mission planning roles while on the ground. ^[6] Becoming a Senior Astronaut often means having already completed one or more long-duration assignments on the International Space Station or similar long-term projects.

# Support Systems

No mission is launched, funded, or managed without a vast operational and administrative structure surrounding the technical teams. These roles ensure compliance, funding, communication, and institutional stability. ^[1][2]

# Administrative and Business

These positions are vital for the agency's functioning as a large federal body. This includes contract specialists who manage the multi-billion dollar contracts NASA awards to private industry, human resources personnel who manage hiring across centers, financial officers who manage congressional appropriations, and legal counsel dealing with everything from procurement law to international space treaties. ^[2]

# Communications and Outreach

NASA has a mandate to inform the public about its findings, making communications experts critical. Public affairs officers, technical writers, and media specialists translate complex engineering and scientific jargon into accessible information for news outlets and the general public. ^[2] These individuals are the voice of the agency across all platforms, including the official NASA websites and social media channels. ^[1]

# Center Specialization

It is also helpful to consider that NASA is not a monolith but a collection of specialized centers across the country. While general positions exist everywhere, certain disciplines cluster based on a center’s primary mission. ^[1][5] For example:

• Johnson Space Center (JSC) in Houston, TX: Heavily focused on human spaceflight operations, training, and medical research.
• Goddard Space Flight Center (GSFC) in Greenbelt, MD: A major hub for scientific research and the operation of many large space observatories.
• Jet Propulsion Laboratory (JPL) in Pasadena, CA: Though run by Caltech, JPL manages robotic exploration missions, meaning roles here are heavily weighted toward deep-space navigation, autonomous robotics, and communication with distant spacecraft. ^[5]

An engineer applying to JPL might focus almost entirely on autonomous systems that need to operate for years without direct human intervention, whereas an engineer at JSC might focus on life support systems designed for short-term, high-risk human interaction. This variation means that simply stating "I am a propulsion engineer" is less informative than saying "I am a propulsion engineer specializing in reusable liquid-fueled rocket development for a center focused on launch vehicle testing". ^[2]

In essence, exploring a career at NASA means looking far past the launch pad. It requires identifying where one's specific expertise—be it coding in Python, drafting international memoranda, performing complex structural stress tests, or interpreting gamma-ray burst data—intersects with the agency’s mission needs, often found listed under the broad umbrellas of administration, engineering, science, or flight operations. ^[1][3]
