Training, Other Qualifications

A bachelor's degree in biochemical or chemical engineering is required for almost all entry-level biochemical engineering jobs, but some basic research positions may require a graduate degree. Faculty positions require graduate degrees. Engineers offering their services directly to the public must be licensed. To keep current with rapidly changing technology, continuing education is important for biochemical engineers.

Beginning biochemical engineering graduates usually work under the supervision of experienced biochemical engineers and, in large companies, also may receive formal classroom or seminar-type training. As new engineers gain knowledge and experience, they are assigned more difficult projects with greater independence to develop designs, solve problems, and make decisions. Biochemical engineers may advance to become technical specialists or to supervise a staff or team of engineers and technicians.

Education and Training

A bachelor's degree in biochemical or chemical engineering is required for all entry-level positions. Research and development jobs at industrial laboratories or with the government usually require graduate training, either a master's degree or a PhD. Faculty positions require a PhD. Many experienced engineers obtain graduate degrees in engineering or in business administration to learn new technology and to broaden their education.

Admissions requirements for entry into a biochemical or chemical engineering university program include a solid background in mathematics (algebra, geometry, trigonometry, calculus) and science (biology, chemistry, physics) with courses in English and humanities. Bachelor's degree programs are typically designed to last four years, but many students find that the program takes between four and five years to complete their studies.

Other Qualifications

Biochemical engineers should be creative, inquisitive, analytical, and detail oriented. They should be able to work as part of a team and to communicate well, both orally and in writing. Communication skills are becoming increasingly important as biochemical engineers frequently interact with specialists in a wide range of fields outside engineering.

In this video a process development engineer explains why his job is rewarding, exciting, and important to everyone.

Nature of the Work

Biochemical engineers act on teams with biologists and chemists to take laboratory processes and ramp them up into large-scale manufacturing. In fact, they are integral to a variety of manufacturing industries, such as food manufacturing and agro-technology. They design the equipment that is used to produce cell cultures of up to thousands of liters. Biochemical engineers grow cell cultures in order to develop natural fuels, improve the efficiency of drugs and pharmaceutical processes, and also develop cures for disease. They formulate the instructions the equipment uses to grow and maintain the cell cultures, and they create the operating specifications used by manufacturing personnel to keep the manufacturing floor running smoothly. Since biochemical engineers work directly on making large volumes of products for human use, they are concerned with manufacturing-plant safety and product safety.

Biochemical engineers design and conduct studies to determine the optimal conditions for cell growth, protein production, and virus expression and recovery using a variety of equipment such as centrifuges and bioreactors. The cell cultures produced in bioreactors can also be used for waste treatment. Biochemical engineers apply their engineering problem-solving skills to studying and learning more about the cell cultures they grow. The discoveries they make are often used to make manufacturing a repeatable and efficient process. Chemists and biologists also use this knowledge to improve their understanding of the molecular workings of the cell.

Biochemical engineers work in corporate laboratories and in research laboratories. This career has a wide focus and includes metabolic engineering, enzyme engineering, and tissue engineering.

  • Metabolic engineers use the tools of molecular genetics to optimize the production of specific metabolites and proteins.
  • Enzyme engineers use and design biocatalysts to produce chemicals and biochemicals.
  • Tissue engineers study all aspects of transplanting living cells to combat disease.

Work Environment

Most biochemical engineers work in office buildings, laboratories, or industrial manufacturing plants. Because many biochemical engineers work on the manufacturing floor, they may come in contact with hazardous chemicals and machinery.

Many biochemical engineers work a standard 40-hour week. At times, deadlines or design standards may bring extra pressure to a job, requiring engineers to work longer hours.
