Simulate a sensor design
Simulate how a sensor's tiny structure responds, tweak its geometry and compare results before building a prototype.
Career profile
Microsystems Engineer
Microsystems engineers design tiny mechanical parts and electronic circuits that work together on one chip.
Some microphones hold a moving part invisible without magnification. MEMS (microelectromechanical systems) engineers shape it, simulate it and check the built device works as planned.
A day in the life
Draw fabrication masks
You draw one mask per fabrication step, and together the layers must free the part to move.
Find why a prototype underperformed
Under a microscope, match the structure to its drawing and probe flaws that might explain weak results.
See if the device holds up
Put a device through environmental stress or aging tests, then note where readings fall below acceptance limits.

Fit, tradeoffs & changing tools
You might like this if…
- You like connecting a physics equation to something you can measure.
- You enjoy finding why a carefully designed object behaves unexpectedly.
- You are willing to revise small details and keep track of what changed.
Things to weigh
- Fabrication-focused jobs can require regular on-site cleanroom and laboratory work.
- Some consumer-device roles include travel to work with suppliers.
Where AI may help
Simulation software helps predict interacting mechanical, electrical, and thermal behavior before fabrication.
What people still lead
You choose assumptions and experiments, then investigate why real measurements disagree with predictions.
What we can’t predict yet
Artificial intelligence is being explored for microsystems design. How much of the design-and-test cycle it will take over remains uncertain.
Pay in context
Earnings
The national figures below give broader engineering context. The workplace salary ranges describe specific experienced MEMS roles, so neither is a starting-pay expectation.
National pay context
For the broader Engineers, All Other group, the 2025 U.S. median was $122,930 a year, or $59.10 an hour. The lowest-paid 10% earned $66,810 or less annually; the highest-paid 10% earned $189,950 or more. These figures cover multiple engineering specialties, and the percentiles are not career stages.
National job prospects
For the same broader Engineers, All Other group, employment is projected to grow 1%–2% over 2024–2034, with about 9,300 openings annually from growth and replacement. These are not forecasts for microsystems engineers alone.
Consumer electronics: device design
An experienced MEMS design role in Boulder advertises $128,300–$193,200 in annual base pay. Skills, qualifications, experience, and location affect the offer; stock programs and benefits are separate.
Biological sensing: senior development
A senior MEMS development role in Cambridge advertises $108,000–$176,000 annually and requires at least five years of relevant experience. Incentives and benefits are additional. Different locations and responsibilities prevent a direct industry-pay comparison.
Getting started
Build device skills during a bachelor's degree
- What the route involves
- Study engineering fundamentals alongside fabrication and testing. Rochester Institute of Technology's microelectronic engineering Bachelor of Science includes cleanroom labs, MEMS electives, and cooperative work experience.
- What it can lead to
- You develop a foundation for device-building and testing work, with projects and workplace experience to bring to applications.
- What to check
- Choose electives and projects deliberately: a microelectronics degree covers more than MEMS.
Specialize through graduate study
- What the route involves
- After a related bachelor's degree, pursue advanced device coursework and research. A Master of Science in electrical engineering can offer a MEMS focus.
- What it can lead to
- You build deeper preparation for specialized engineering problems and, if desired, doctoral research.
- What to check
- Programs set their own admission requirements; changing from another engineering field may require prerequisite courses.
Look for engineering programs where you can design, fabricate, and measure small devices. Two education routes build toward this work.
After entry
Career paths
This starts where the entry routes leave off: early work, growing capability, and advancement or specialization.
Get established
Learn the device's test methods and records. Make your measurements repeatable before interpreting unexpected results.
Connect design with fabrication
Take responsibility for a device change, working through how its layer patterns and fabrication process constrain the final structure.
Lead a device into production
Advance toward technical leadership: guide a sensor from concept through fabrication and help transfer the process to a manufacturing partner.
Where you can work
Consumer-device design teams
Work with acoustics, electronics, and mechanical specialists. Supplier discussions connect your models to components intended for finished products.
- Office
- Lab
Biological-sensor startups
Move between cleanroom fabrication and lab measurements, working with bioengineers to connect tiny silicon structures with biological samples.
- Indoors
- Lab
National-laboratory research facilities
Develop custom microsystems in facilities combining offices, labs, and cleanrooms. Small batches of experimental devices and demanding reliability problems can shape the work.
- Office
- Lab
Try it
See whether the job clicks before you commit to the path.
On paper, sketch a tiny bridge held at both ends above a surface. Draw separate layer views showing its supports, bridge, and the space beneath it. Explain how removing a temporary layer could leave the bridge free. Notice whether reasoning from flat patterns to a moving structure interests you.
Stay safe: Keep this a drawing exercise; actual microfabrication requires specialized facilities and training.
