Overview
Precision engineers design machines, fixtures, processes and equipment where very small tolerances, repeatability and stable operation matter.
In job descriptions, look for precision engineering, technical drawings, prototypes, test procedures, calibration, part requirements, scientific equipment, microelectromechanical systems and project responsibility.

Open in Job ExplorerWhat the work can involve
Precision engineering focuses on designs that must work with very low tolerances over repeated use. Work may cover fixtures, machines, scientific equipment, prototypes, test procedures and technical requirement reviews.
Skills and specializations
Important skills include technical drawings, precision mechanics, calibration, part requirements, design specifications, prototype testing, test data analysis and technical drawing software. Some roles add electronics, mechatronics or product data management.
Salary context
Salary context depends on design authority, tolerance complexity, test responsibility, project management, prototype ownership, regulated equipment and whether the engineer signs off requirements or supports a senior design lead.
Career paths
Career paths can grow from mechanical design, test engineering or prototype work into senior precision engineering, project leadership, scientific equipment design, manufacturing engineering or specialist calibration roles.
Good to know
Check whether the vacancy names the product scale, tolerances, drawing tools, testing methods and sign-off responsibility. Precision engineering should be separated from general mechanical design when the tolerance and repeatability demands are central.
