redirect a specific url to another url with .htaccess

If you want the rule to only execute when the domain is "tz433.tld", you need this condition:

RewriteCond %{HTTP_HOST} ^(www\.)?tz433\.tld

And to redirect "jobs/" and "jobs" to "tz433.tld/about-us/jobs.html", you can try one of these:

RewriteRule ^jobs/? /about-us/jobs.html [R=301,L]
# or
RewriteRule ^jobs/? http://tz433.tld/about-us/jobs.html [R=301,L]

If someone is just interested in simple redirect you can try this:

Redirect /URL URLtoRedirect

e.g

Redirect /old-url https://mywebsite.com/new-url
