Translation guide
The English word 'engineer' covers a wide range of technical professions. In Japanese, the most common equivalent is エンジニア, a loanword used broadly for IT, software, and technical roles. For traditional engineering fields (civil, mechanical, electrical), 技師 or 技術者 are more formal and precise. This guide helps learners choose the right term based on context.

A more formal and traditional term for 'engineer' or 'technician'. It emphasizes technical expertise and is used across various engineering fields, but can sound slightly stiff in casual conversation.
Often used in official titles or licenses, such as 'civil engineer' (土木技師) or 'mechanical engineer' (機械技師). It implies a certified or professional status and is less common in everyday speech.
To specify an engineer in a classical engineering discipline, often with a formal or professional connotation.
To form compound job titles like 'software engineer', 'network engineer', etc.

エンジニア is the most common and modern term, used widely in IT and tech. 技術者 is a formal, traditional term for engineers in any field, often used in official contexts. 技師 is typically used for licensed or certified professionals, like 建築技師 (architectural engineer). For everyday conversation about tech jobs, エンジニア is safest.
I work as an IT engineer.
I want to become an engineer.
An engineer's job is to solve problems.
彼は優秀な技術者です。

He is a first-class architectural engineer.
The standard term for engineers in traditional fields. It is neutral and widely used in job titles and descriptions.
I work as a civil engineer.
The demand for electrical engineers is increasing.
Used in formal titles and certifications, such as 機械技師 (mechanical engineer) or 電気技師 (electrical engineer). It often implies a licensed professional.
I obtained a mechanical engineer license.
Also used for traditional engineering fields, especially in international or modern contexts, but 技術者 is more common in domestic settings.
He is a mechanical engineer.
Used for more traditional or formal titles, e.g., 電気技術者 (electrical engineer), 建築技術者 (architectural engineer).
She is an environmental engineer.
The standard term for a train driver or operator. It is used for professional drivers of trains and other vehicles.
He is a train engineer.
Specifically refers to a steam locomotive engineer or a ship's engineer. It is less common today but still used in historical or specific contexts.

The standard term for a military engineer or sapper. It refers to soldiers who handle construction, demolition, and other engineering tasks.
He is an army engineer.

In Japanese, エンジニア never means a train driver. Use 運転士 (うんてんし) for that meaning. Using エンジニア for a train operator will cause confusion.
She is a brilliant engineer.
