A device engineer designs, builds, tests, and improves physical devices, most commonly in two industries: medical devices and semiconductors. The exact day-to-day work depends heavily on which of these paths you’re in, but the core thread is the same. You take a product from concept through prototyping, testing, and manufacturing, solving technical problems at every stage.
Medical Device Engineers
Medical device engineers develop equipment and instruments used in healthcare, from surgical tools and imaging machines to artificial organs and implantable devices. The work spans the entire product lifecycle. Early on, that means researching what clinicians and patients actually need, then translating those needs into a design that’s both effective and cost-efficient to manufacture.
Design is only part of the job. Medical device engineers run trials to verify that their equipment is safe and performs as intended. They refine prototypes based on test results, work through regulatory requirements, and eventually hand off a design that can be produced at scale. Because these products go into or onto human bodies, the stakes for precision and reliability are unusually high. You’ll spend significant time documenting your design choices and justifying them to regulatory reviewers.
Within this field, some engineers specialize in designing artificial organs or prosthetics that replace or enhance biological components. Others focus on diagnostic equipment, drug delivery systems, or the manufacturing processes themselves.
Semiconductor Device Engineers
On the electronics side, a semiconductor device engineer designs and optimizes the tiny components that power modern technology: transistors, diodes, and integrated circuits. This work requires a deep understanding of physics at the atomic scale, since the behavior of electrons through different materials determines whether a chip meets its performance targets.
Day-to-day responsibilities include running simulations of how a device will perform, then working with fabrication teams to actually build it on silicon wafers in a cleanroom environment. When a device doesn’t hit its targets for speed, power consumption, or reliability, you dig into the physics to figure out why and adjust the design or the manufacturing process. A major part of the role is improving yield, which means increasing the percentage of chips that come off the production line working correctly.
Semiconductor device engineers also support technology transfers, taking a design that works in a research lab and scaling it up for high-volume manufacturing. This involves close coordination with process engineers, integration engineers, and layout specialists to make sure a design that looks good in simulation can actually be built reliably millions of times over.
Cross-Functional Collaboration
Regardless of industry, device engineers rarely work in isolation. In medical device development, you’ll collaborate with regulatory specialists, clinical teams who understand how a product will be used in practice, supply chain partners who influence what materials and components are available, and manufacturing engineers who need to assemble and test your design at scale. Getting all of these groups aligned early in the process prevents costly redesigns later.
In semiconductors, the collaboration looks different but is just as constant. You’ll work alongside process engineers who control fabrication steps, design engineers who lay out circuits, and reliability engineers who stress-test finished devices. Large semiconductor companies often have teams spread across multiple sites, so coordinating between an R&D lab and a high-volume manufacturing facility is a routine part of the job.
Tools and Software
Device engineers rely on specialized software depending on their discipline. Mechanical and medical device engineers typically use 3D design tools like SolidWorks or Autodesk Inventor for modeling parts and assemblies, along with simulation platforms like ANSYS for testing how a design will behave under real-world stresses, temperatures, and forces without building a physical prototype first. MATLAB is widely used for technical computing, data analysis, and running custom simulations.
Electronics-focused device engineers use tools like Altium Designer for designing printed circuit boards and schematic capture. Semiconductor engineers work with specialized simulation software to model how electrical current flows through nanoscale structures, and they use statistical tools to analyze manufacturing data and track yield improvements. AutoCAD remains a foundational tool across multiple engineering disciplines for 2D and 3D drafting.
Education and Qualifications
A bachelor’s degree is the standard entry point. For medical device engineering, that degree is typically in biomedical engineering, bioengineering, or a related field like mechanical or electrical engineering supplemented with biology coursework. Bachelor’s programs in biomedical engineering combine biological sciences with core engineering subjects like fluid mechanics, circuit design, and biomaterials, and they usually include hands-on design projects.
For semiconductor roles, employers look for degrees in electrical engineering, physics, or materials science, with strong coursework in semiconductor physics and device fabrication principles. Co-ops and internships during school carry real weight in both fields, giving you practical experience that classroom work alone can’t replicate.
A graduate degree isn’t always required to start, but it opens doors. Leading a research team or working on cutting-edge technology development typically requires a master’s or PhD. Some engineers also pursue a Professional Engineer (PE) license, which requires passing exams and accumulating supervised work experience, though this is more common in certain subfields than others.
Work Environment
Most device engineers split their time between office-based design work and hands-on environments. Medical device engineers may work in laboratories, testing facilities, or manufacturing plants. Semiconductor engineers spend time in cleanrooms, which are tightly controlled environments where even a speck of dust can ruin a chip.
The industries that employ the most device engineers include engineering services firms, semiconductor manufacturers, telecommunications companies, aerospace manufacturers, and companies specializing in navigational, measuring, and electromedical instruments. Federal government agencies also employ a notable share of electronics engineers. Some travel is common, particularly when visiting manufacturing sites, supplier facilities, or clinical testing locations.
Salary and Job Growth
Compensation varies by specialization, experience, and location, but the field pays well. Computer hardware engineers, a category that overlaps significantly with device engineering in electronics, earned a median salary of $155,020 per year as of May 2024, according to the Bureau of Labor Statistics. Employment in that category is projected to grow 7% from 2024 to 2034, which the BLS classifies as much faster than average.
Medical device engineers, typically classified under biomedical engineering, generally start at lower salaries but see strong growth as they gain experience or move into management. Engineers with graduate degrees or specialized expertise in high-demand areas like implantable electronics or advanced semiconductor nodes tend to command salaries at the upper end of the range. Geographic location matters too: major hubs for semiconductor work include the San Francisco Bay Area, Austin, and Portland, while medical device roles cluster in areas like Minneapolis, Boston, and parts of Southern California.
