Houston's Major Industries and Employers: Job Seeker's Guide
Houston is one of the largest and most economically diverse cities in the United States. It is widely known as the energy capital of the world, but its job market reaches far beyond oil and gas, into healthcare, aerospace, shipping, manufacturing, construction and a growing tech sector. Texas also has no state personal income tax, and housing in the Houston area has historically been more affordable than in many other large US metros. If you are looking for work in the city or considering a move, this guide covers Houston's major industries and the kinds of employers hiring in each.
Energy
Energy remains central to Houston's economy. The region is home to the headquarters or major operations of many of the world's best-known energy companies, including ExxonMobil's large campus in the north Houston suburb of Spring, Chevron, which announced in 2024 that it was moving its headquarters to Houston, and ConocoPhillips, Phillips 66 and Occidental. Oilfield services firms such as SLB, Halliburton and Baker Hughes also have major Houston operations.
Energy jobs include:
- Petroleum, chemical, mechanical, electrical and process engineers
- Geoscientists and data scientists
- Field technicians, operators and maintenance crews
- Finance, accounting, legal, supply chain and HR professionals
- IT, cybersecurity and software engineers supporting operations
Houston is also positioning itself in the energy transition, with growing activity in carbon capture, hydrogen, wind, solar and battery projects. Many traditional energy companies are hiring for these lower-carbon initiatives, creating roles that blend existing engineering skills with new technologies.
Healthcare and life sciences
The Texas Medical Center, often described as the largest medical complex in the world, makes healthcare one of Houston's biggest employment sectors. It includes institutions such as Houston Methodist, Memorial Hermann, the University of Texas MD Anderson Cancer Center, Texas Children's Hospital, Baylor College of Medicine and UTHealth Houston. Beyond the medical center, hospital systems and clinics operate across the metro area.
Healthcare jobs range from nurses, physicians and therapists to medical assistants, lab and imaging technicians, researchers, patient access staff, IT professionals and administrators. Life sciences and biotech activity is growing too, with research and startup space developing around the medical center.
Aerospace
NASA's Johnson Space Center in the Clear Lake area is home to human spaceflight operations and astronaut training, earning Houston the nickname "Space City." A cluster of aerospace contractors and commercial space companies has grown around it, and the Houston Spaceport at Ellington Airport supports newer space businesses. Roles include aerospace, mechanical and electrical engineers, software engineers, technicians and program managers. Some positions require US citizenship or security clearance eligibility.
Port, logistics and transportation
The Port of Houston and the Houston Ship Channel make the region one of the busiest shipping hubs in the country, supported by extensive rail, highway and airport infrastructure. This creates demand for:
- CDL truck drivers and delivery drivers
- Warehouse associates, forklift operators and inventory specialists
- Logistics coordinators, dispatchers and supply chain analysts
- Customs brokers and freight forwarders
- Maritime and port operations staff
Manufacturing and petrochemicals
The Houston area has one of the largest concentrations of petrochemical plants and refineries in the United States, particularly along the Ship Channel and in nearby communities like Pasadena, Baytown and Deer Park. Manufacturers also produce equipment, metals, plastics and industrial products. Jobs include process operators, maintenance technicians, instrumentation and electrical techs, welders, machinists, quality inspectors and plant engineers.
Construction and skilled trades
Population growth and continuous industrial and commercial building keep construction busy across the region. Electricians, plumbers, pipefitters, HVAC technicians, welders, heavy equipment operators, estimators and project managers are in steady demand. Industrial construction for energy and petrochemical facilities is a particular specialty.
Corporate headquarters and professional services
Houston hosts the headquarters of many large companies across industries, including food distributor Sysco and technology company Hewlett Packard Enterprise, alongside major law, accounting, engineering and consulting firms. These employers hire for finance, sales, marketing, legal, HR, operations and administrative roles.
Technology
Houston's tech sector is growing, driven by energy tech, health tech, aerospace and a startup ecosystem anchored by innovation hubs such as the Ion in Midtown. Software engineers, data scientists, cybersecurity specialists and IT professionals find opportunities both at tech startups and inside large energy, healthcare and industrial companies.
Education, government and services
Universities including Rice University, the University of Houston and Texas Southern University, large public school districts, and city and county government are major employers. Retail, hospitality and food service jobs are plentiful across the region as well.
Tips for job seekers in Houston
- Consider the commute. Greater Houston is spread out, and traffic on major freeways can be heavy. Think about where jobs cluster, such as Downtown, the Energy Corridor, the Texas Medical Center, the Galleria area, The Woodlands and Clear Lake.
- Highlight safety training. For industrial roles, certifications such as OSHA training and TWIC cards for port access can make you more competitive.
- Bilingual skills help. Houston is one of the most diverse cities in the country, and Spanish and other languages are valuable in many roles.
