Much of the work starts with direct observation: watching people do their jobs, running or witnessing tests, and interviewing or surveying users about fatigue, comfort, or usability. From there, ergonomists inspect worksites for physical hazards like heavy loads or repetitive motion and write up recommendations, then advocate for the end user's perspective alongside engineers, designers, and managers who may be focused elsewhere. It's a desk-heavy, indoor role but grounded in real fieldwork, and it typically requires a master's degree, with a PhD common among those doing original research.
Pros
High upside earning potential, up to $160k
Strong pay even at the entry level
Much faster than average projected job growth (11% over the next decade)
Cons
Requires a master's degree, with a PhD common for research-focused roles
Highly structured work following set procedures, with less day-to-day variety
Work often depends on site visits and interviews, adding coordination overhead beyond desk research
A typical day
The morning is a usability test behind one-way glass: a nurse volunteer works through a new infusion pump interface while the engineer logs every hesitation and wrong tap — each one a future medication error the design has to prevent. Analysis follows: coding the session data, comparing error rates against the older interface, and drafting design changes ranked by risk. After lunch the engineer is on a factory floor with a force gauge and a posture-analysis app, evaluating a workstation blamed for wrist injuries, then sketching a fixture that would eliminate the awkward reach. The afternoon closes in a design review, arguing — with data, not opinion — that the confirmation button belongs where the thumb already rests.
Tasks at the job
Collect data through direct observation of work activities or witnessing the conduct of tests.
Conduct interviews or surveys of users or customers to collect information on topics, such as requirements, needs, fatigue, ergonomics, or interfaces.
Advocate for end users in collaboration with other professionals, including engineers, designers, managers, or customers.
Inspect work sites to identify physical hazards.
Prepare reports or presentations summarizing results or conclusions of human factors engineering or ergonomics activities, such as testing, investigation, or validation.
Recommend workplace changes to improve health and safety, using knowledge of potentially harmful factors, such as heavy loads or repetitive motions.
Workplace & working conditions
Work happens indoors in a climate-controlled setting.
There's a regular, moderate amount of time pressure, and you're expected to exercise significant independent judgment day to day. The work is highly structured, following set procedures.
Education necessary or common
Master's degree in human factors, industrial engineering, or psychology; a PhD is common for research roles
