Auditors will take a company's size into account. I work for a smaller company with approximately 60-70 employees. In our organizational structure I am listed as QA and Practitioner. In addition to that, I am listed as backup to: President, Ops Manager, QC, Bakery Supervisor and Packaging Supervisor.
Come to think of it, at one point I believe I was back up to maintenance during our initial audit... might still be. I'm going to go look into that. Point being, in smaller companies you're forced to "wear many hats" as they say and auditors understand that.
Company size aside, Ops Manager fits the criteria laid out in 18.104.22.168
