A STEM career is any job rooted in one of four fields: science, technology, engineering, or mathematics. These careers span a huge range of industries and education levels, from technicians with associate’s degrees to researchers with doctorates. As a group, STEM occupations are projected to grow 10.4% by 2033, more than double the 4.0% growth rate expected across all occupations.
The Four Pillars of STEM
The acronym breaks down into broad categories, each covering dozens of specializations:
- Science includes fields like biology, chemistry, environmental science, geoscience, and physics. Jobs range from microbiologists and epidemiologists to soil and plant scientists.
- Technology covers computer science, information systems, cybersecurity, and data science. Roles include information security analysts, computer network architects, and systems managers.
- Engineering spans chemical, mechanical, civil, bioprocess, and robotics engineering, along with technician roles that support them.
- Mathematics encompasses actuaries, statisticians, and mathematicians, plus the growing number of data-focused roles that rely heavily on quantitative analysis.
What STEM Jobs Actually Look Like
STEM careers aren’t limited to lab coats and chalkboards. A chemical technician might spend the day running quality tests in a manufacturing plant. An information security analyst monitors networks for threats from a home office. A civil engineering technician visits construction sites to ensure structures match design specifications. An epidemiologist tracks disease outbreaks by analyzing population health data.
Newer roles are blurring traditional boundaries. Bioinformatics scientists use computational tools to analyze genetic data. Clinical data scientists work with information generated during drug trials. AI research scientists in biotech develop machine learning methods tailored to biological problems. These hybrid positions reflect a broader trend: as artificial intelligence reshapes industries, STEM careers increasingly combine deep scientific knowledge with computational skills.
Pay and Job Outlook
STEM workers earn significantly more than the national average. In 2021, median earnings for full-time STEM workers were $69,000, compared to $49,900 for non-STEM workers. That’s a gap of about $19,100 per year across all education levels.
The salary advantage holds even at the same level of education, but it varies by specialty. Roles in computer science and engineering tend to pay the most at the bachelor’s degree level, while some science and math positions require graduate degrees before salaries climb substantially. Actuaries, for instance, typically need a bachelor’s degree, while statisticians and physicists often need a master’s or doctorate.
Education Requirements Are More Flexible Than You’d Think
One of the biggest misconceptions about STEM is that you need a four-year degree to get started. In reality, the largest proportion of STEM workers in 2021 had not earned a bachelor’s degree. About 24% had never attended college, 17% had some college but no degree, and 12% held an associate’s degree. Only 28% had a bachelor’s, and 20% had a master’s or higher.
The education you need depends entirely on the type of STEM work. Among middle-skill STEM occupations (think technicians, installers, and IT support), 52% of workers had never attended college. These roles often rely on hands-on training, apprenticeships, or professional certifications. On the other end, 47% of workers in core science and engineering roles held at least a bachelor’s degree.
Credentials beyond degrees also matter. About 46% of all STEM workers held a professional certification, license, or educational certificate in 2020. Licensing is especially common in health-related STEM roles. Certifications in areas like cybersecurity, project management, or specific programming languages can open doors in technology fields without requiring a traditional degree path.
Skills That Matter Beyond Technical Knowledge
Technical expertise gets you in the door, but STEM employers consistently look for a set of broader capabilities. Communication ranks at the top: the ability to explain complex work to people outside your specialty, whether that’s a client, a manager, or a cross-functional team. Problem-solving is a close second, particularly the skill of breaking a large, ambiguous challenge into smaller pieces that can be tackled systematically.
Organization, time management, and teamwork round out the list. STEM projects rarely happen in isolation. Engineers coordinate with designers, scientists collaborate with data analysts, and software developers work alongside product managers. The ability to set clear goals, manage competing deadlines, and contribute to a team’s shared objectives often separates someone who does good technical work from someone who advances into leadership.
Remote and Hybrid Work in STEM
Not all STEM jobs require you to be on-site. Fields that center on digital work have adapted quickly to remote and hybrid arrangements. Software developers, data scientists, and cybersecurity specialists are among the roles most commonly done remotely. Bioinformatics analysts, who decode complex biological data using computational tools, also work remotely with increasing frequency.
Even some hardware-oriented roles have shifted. Robotics engineers can now design, program, and simulate systems remotely, testing and iterating without touching a physical machine. That said, many STEM careers in laboratory science, field research, healthcare, and manufacturing still require a physical presence. Your flexibility depends heavily on the specific role and employer.
Who Works in STEM Today
The STEM workforce doesn’t yet reflect the full diversity of the population. In 2021, about 24% of all U.S. workers held a STEM job, but only 18% of female workers did, compared to 30% of male workers. Black workers made up 8% of the STEM workforce versus 11% of the total workforce. Hispanic workers represented 15% of STEM occupations, below their 18% share of all jobs. Asian workers were overrepresented in STEM at 10%, compared to 6% of the overall workforce.
These gaps have driven significant investment in STEM education and outreach programs, particularly at the K-12 level and in community colleges that serve as pipelines for middle-skill STEM roles.
STEM vs. STEAM
You may also see the term STEAM, which adds “arts” to the mix. STEAM-focused education integrates design, visual arts, music, and humanities alongside traditional STEM subjects. The idea is that creative and analytical thinking work best together. An architect uses both engineering principles and design sensibility. A graphic designer relies on technology tools and artistic judgment. Urban planners, sound engineers, product designers, and conservators all fall under the STEAM umbrella.
In practice, STEM and STEAM aren’t competing categories. STEAM simply acknowledges that many modern careers require people who can think both analytically and creatively, and that programmers and engineers increasingly collaborate with artists to develop software, products, and visual content.
