Does this opportunity sound like a good corporate finance role?

I am wondering what your thoughts are on the following job opportunity. I left my MM bank after two years as an analyst. I am interviewing for a junior role in the corporate finance team of a mid sized utility (c. $2.0bn TEV). The role would initially involve working in the finance team building a detailed bottom up operational model of the business, which would be used to drive business planning and regulatory analysis. In addition, the business was recently acquired by a consortium of infrastructure funds, and I would use the model to produce IRR and dividend yield metrics for the owners. I would also work with the equity owners on a regular basis, and would be reporting to the Financial Controller.

Does this role, based on the information I have provided, sound like a decent role for someone with two years of M&A experience? I like the fact that it would offer a much better lifestyle than banking / PE, and I would develop a lot of industry expertise, and hopefully have regular contact with senior guys at the firm. However, I would be worried about the career progression opportunities, pay, and exit options, after a few years, of working for a relatively small privately owned company, in such a niche area. In addition it is initially a pretty modelling heavy role, am not sure if this is a good or bad thing.
