Bioengineering
Engineer living systems - design biological circuits, grow tissues, and program cells
Overview
Bioengineering applies engineering principles to design, build, and manipulate biological systems. Unlike biomedical engineering, which focuses on medical devices and clinical tools, bioengineering works at the level of cells, genes, and biological pathways. Bioengineers design genetic circuits the way electrical engineers design electronic ones, program microorganisms to produce useful chemicals, and build synthetic biological systems from the ground up.
What You'll Actually Do
A typical day might involve designing a genetic circuit in software, then building it in the lab by assembling DNA sequences and transforming them into cells. You run experiments to test whether your engineered organisms behave as predicted, analyze data from sequencing runs and growth assays, and iterate on your designs. Some bioengineers work at the computational level, modeling biological networks and running simulations before anything reaches the bench. Others focus on fermentation and bioprocess scale-up, turning lab-scale results into production-ready systems. The work is deeply interdisciplinary, drawing on molecular biology, genetics, chemistry, computer science, and control theory.
Specializations
Synthetic biology focuses on designing novel biological circuits, pathways, and organisms that do not exist in nature. Metabolic engineering optimizes cellular metabolism to produce fuels, pharmaceuticals, and industrial chemicals at scale. Genetic engineering and gene editing use tools like CRISPR to modify DNA sequences for research and therapeutic applications. Bioprocess engineering deals with scaling up biological production systems from lab flasks to industrial bioreactors. Computational biology and bioinformatics use software to model, simulate, and analyze biological data. Tissue engineering grows functional tissues and organoids for research, drug testing, and eventually transplantation.
Who's Hiring
Ginkgo Bioworks is building a platform for programming cells across industries from agriculture to pharmaceuticals. Corteva Agriscience engineers crops with improved traits using synthetic biology. Twist Bioscience manufactures synthetic DNA at scale. Cortical Labs is pioneering biological computing by integrating living neurons with silicon chips. Moderna applies bioengineering to mRNA therapeutics and vaccines. Zymergen (acquired by Ginkgo) and Amyris develop bio-based materials and products. Smaller startups like Asimov design genetic circuits with CAD tools, and companies like Mammoth Biosciences develop next-generation CRISPR diagnostics.
Career Path
Entry-level positions include research associate and bioprocess engineer, where you run experiments, maintain cell cultures, and support senior scientists. With a few years of experience you move into scientist or senior bioprocess engineer roles, leading projects and making key design decisions. Principal scientists and staff bioengineers set the technical direction for entire programs. At startups, you might take on a broader role early, combining lab work with computational design and business development. Leadership paths include director of synthetic biology, VP of research, and chief scientific officer.
Licensing and Certification
There is no standard PE licensure path for bioengineering. The FE exam can be taken in related disciplines like chemical or biological engineering, but it is not commonly required for bioengineering roles. The field relies more on academic credentials and demonstrated research ability. A PhD is common for research-focused positions, though many industry roles are accessible with a BS or MS in bioengineering, chemical engineering, molecular biology, or a related field. Biosafety certifications and familiarity with biosafety level (BSL) protocols are important for lab-based roles. Regulatory knowledge around FDA and EPA guidelines matters for anyone working on products that enter the market.
