How to use these keywords

Start from the job ad. Mark the requirements it repeats or lists first, and focus on those.
Only use what you can back up. If an interviewer asks about a keyword, you should have an example.
Put tools and certifications in your skills section, and prove them in your experience bullets.
Use the employer's wording for work you've actually done, for example their name for a system or process.
Add scope and results: numbers, volumes, settings and outcomes make a keyword believable.

Questions

Should I add every Third Engineer keyword to my CV / resume?

No. Use the ones the specific job ad asks for and that you can back up with real experience. A long list of unsupported keywords makes a CV / resume less credible, not more.

Where should the keywords go?

Tools, systems and certifications belong in your skills section. Prove them in your experience bullets, and mention the two or three most important ones in your summary.

Do I need the exact wording from the job ad?

Where it's accurate, yes. Recruiters and screening systems often search for the employer's own terms, so use their name for a tool, certification or process you have actually worked with.
