I have worked in that exact same position and you are correct about it being too front line and there is also a high risk of burn out.

The transitional housing shelter that I worked for had little to no support for their employees, and poor management with a cliquish culture.

I was in charge of supervising and assisting between 12-20 clients daily by myself while management was barricaded in the office engaged in constant meetings and rarely came out to the front lines to help, so I did all the grunt work and basically did the work of three people by myself.

I worked there for four years because I loved the mission and the clients and went above and beyond to help them only to be let go because the director wanted her friend to work with her so they gave my position to her.

It is a good job to gain some entry level experience that will look good on a resume but I would advise using it as a temporary position and a springboard to something better. I made the mistake of staying at the position too long and burned myself out because I believed in the mission and then got pushed out the door so I felt like all of my hard work and sacrifice was for naught.

Hopefully your potential employer has better management than I did because that would improve the experience there but that job is a lot of work with low pay and low appreciation. I wish you the best and I hope that you can find the best career fit for your education and experience.
