Average Industrial Engineer Salary in WashingtonNo State Income Tax

Industrial engineers design efficient systems that integrate people, machines, materials, information, and energy to produce a product or provide a service. Unlike other engineering disciplines focused on specific technologies, industrial engineering is inherently cross-functional — applying mathematical modeling, statistical analysis, operations research, and human factors principles to eliminate waste, reduce costs, and improve quality in manufacturing, healthcare, logistics, and service industries. The BLS reports a median annual wage of $99,380, making it one of the better-compensated engineering disciplines accessible via a 4-year degree. Industrial engineers working in management consulting, semiconductor manufacturing, aerospace, and pharmaceutical sectors often earn substantially above this median.

In Washington, industrial engineers earn an average of $121,636 per year as of 2026, with salaries ranging from $78,686 for entry-level roles to $171,186 for the most experienced professionals — +22.4% above the national average. Pay is influenced most by industry sector — semiconductor, aerospace, defense, and pharmaceutical manufacturers pay the highest industrial engineering wages; food processing and textiles pay toward the lower end, geographic location — california's silicon valley and semiconductor corridors, washington (boeing), and texas (oil/gas, semiconductors) pay above-national-average wages, and the specific metro area within Washington.
