Can an introvert do well in ECM?

I'm very introverted, I'm really quiet, keep to myself, and am normally the silent one in group situations. I'm not at the extreme end of being socially awkward with no people skills, I can hold a conversation with others but I'm just naturally very quiet.

I enjoy banking but I've decided I don't like the hours and wanted a role where I had better work-life balance and stable hours so I've spoken with my managers who suggested moving into my banks ECM team where culture is really good with decent hours. I was introduced to the ECM team and they liked me and invited me to join their team but warned me that the role is much more sales heavy than industry teams so I would be expected to be on the phone to investors/clients answering queries and attending investor/client meetings, participate in pitches etc.

The role of ECM sounds very interesting to me and the team has a great culture with good hours but it's the complete opposite of my natural personality of normally avoiding people and being quiet, when I was younger I used to tell myself 'I would never ever want to be a salesman'... I've always been a maths geek. I feel buyside would have been ideal i.e. a hedge fund would be perfect for my personality and PE sounds very interesting, but I want a role where I would have good stable hours.

Am I setting myself up for failure by moving into an ECM role or is it possible for an introvert to be successful in a sales/people orientated role?

Also if there are any other introverts who are in the industry it would be great to also hear your thoughts.
