What is a chemical engineer?

Chemical engineers are professionals who apply principles of chemistry, physics, mathematics, biology, and engineering to solve problems involving the production or use of chemicals, fuel, drugs, food, and many other products. They design processes and equipment for large-scale manufacturing, plan and test production methods, and oversee facility operations. Chemical engineers work in a variety of industries, including pharmaceuticals, energy, food processing, and environmental health and safety. Their work helps turn raw materials into useful products safely, efficiently, and sustainably.

What are the key skills and qualifications needed to thrive as a chemical engineer, and why are they important?

To thrive as a Chemical Engineer, you need a solid background in chemistry, mathematics, and process engineering, usually supported by a bachelor's degree in chemical engineering or a related field. Familiarity with process simulation software (such as Aspen Plus or HYSYS), safety regulations, and laboratory analysis tools is commonly required. Strong problem-solving, project management, and teamwork skills help Chemical Engineers excel in collaborative and dynamic environments. These competencies are vital for designing efficient processes, ensuring safety, and driving innovation in chemical manufacturing and related industries.

What are some common challenges chemical engineers face when working on process optimization projects?

Chemical engineers often encounter challenges such as balancing safety requirements with production efficiency, troubleshooting complex process issues, and adapting to new technologies or regulations. These projects typically require close collaboration with multidisciplinary teams, including operators, quality control, and maintenance staff, to implement changes without disrupting ongoing operations. Staying up-to-date with industry best practices and maintaining strong problem-solving skills are essential to successfully navigate these challenges and drive continuous improvement.

What is the difference between Chemical Engineer vs Process Engineer?

AspectChemical EngineerProcess Engineer
CredentialsBachelor's degree in chemical engineering; often licensed as a Professional Engineer (PE)Bachelor's degree in chemical, process, or industrial engineering; may also pursue PE licensure
Work EnvironmentFactories, laboratories, research facilities, and industrial plantsManufacturing plants, process design, and optimization settings
Industry UsageChemical, pharmaceuticals, energy, and materials industriesManufacturing, refining, and process industries

Both Chemical Engineers and Process Engineers work in industrial environments and often require similar educational backgrounds. Chemical Engineers typically focus on designing and developing chemical processes, while Process Engineers optimize and improve existing manufacturing processes. Their roles often overlap, but their primary responsibilities differ slightly based on project scope and focus.

Is there a high demand for chemical engineers?

Chemical engineers are in high demand across industries such as pharmaceuticals, energy, and manufacturing due to ongoing innovation and the need for process optimization. Employment opportunities are expected to grow faster than the average for all occupations, especially for those with strong technical skills and relevant certifications.

What type of jobs do chemical engineers do?

Chemical engineers design, develop, and optimize processes for producing chemicals, fuels, pharmaceuticals, and materials. They work in industries such as manufacturing, energy, and environmental protection, often using tools like process simulation software and adhering to safety and environmental regulations.

  • Develop and apply multiscale modeling approaches to catalytic systems
  • Conduct spectroscopy simulations, including techniques such as XANES, EXAFS, and Mössbauer spectroscopy
  • Develop and implement machine learning methods and automated workflows for complex catalytic simulations
  • Collaborate closely with experimental researchers to interpret results and guide catalyst development
  • Contribute to proposal development and funding applications
  • Mentor postdoctoral researchers and graduate students

Position Requirements
  • Ph.D. in physical chemistry, inorganic chemistry, computational materials science, chemical engineering, or a related field, along with 3-6 years of postdoctoral research experience
  • Comprehensive understanding of quantum mechanics and catalysis
  • Extensive experience in heterogeneous thermal catalysis and electrocatalysis, including:
    • catalyst design
    • mechanistic studies
    • microkinetic modeling
    • reactor modeling
  • Strong computational expertise in applying quantum mechanical methods to determine electronic structure, catalytic properties, and reaction mechanisms
  • Demonstrated experience in spectroscopy simulations, including XANES, EXAFS, and Mössbauer spectroscopy
  • Proficiency in Python and relevant computational platforms
  • At least 1-2 years of experience adapting and implementing AI/ML methods in catalysis, including:
    • machine learning interatomic potentials
    • agentic workflows
  • Experience in proposal writing and funding applications
  • Experience mentoring postdoctoral researchers and graduate students
  • Excellent written and oral communication skills
  • Ability to model Argonne's core values of impact, safety, respect, integrity, and teamwork

Preferred Qualifications
  • Experience with PGM-free oxygen reduction reaction (ORR) catalysts
  • Experience with CO₂ reduction catalysis
