"We can help you with your job. If nothing else, it's good for a Spectre agent to learn basic engineering skills," Nihlus remarks as they walk. "And if it gets too difficult for you, I'm always willing to switch. There's significantly less engineering in cleaning and security."

Less chances of people dying from your mistakes too, but the Spectre very carefully leaves that out for the time being. He trusts Tali not to give Shepard anything that actually would put the crew in jeopardy if messed up at any rate.
