Hey there. The find people enrichment is typically the best for this. As you can see here, you start with a company name and domain, and then when you get the options of job titles to include, you add your filter. If that doesn't work, I recommend enriching that company to find their LinkedIn page, and then using Claygent to find LinkedIn profiles of people that are in a specific job function. However the former will cost you way less credits and is much more efficient.
