I currently work at a large IT consulting firm as an **agile project manager**.
I am PMI-PMP, ACP certified and have **3-4 yrs of scrum/xp experience** of which **2 years as a scrum master**. I am contemplating a job offer for the role of **Iteration manager / Scrum Master** with a large e-commerce retailer. The big plus for me is to get ecommerce experience exp in large scalable systems - and it offers an immediate job opportunity.

The scrum master/IM role (Typically and in this case) does not have stakeholder management responsibilities, staffing, people management, risk management and P&L responsibilities - all of these I currently do in my role and I know is high demand for PM jobs. I do not want to make a career out of scrum-mastering or becoming an agile coach. My aspiration is to grow to program manager or business development roles and consider this opportunity to gain some e-Com experience.

I would like to know 

1. How do recruiters & hiring managers view this transition from PM to SM - will this transition hurt me if I want to shift back to Proj / program mgmt roles after gaining e-commerce experience ?

2. Does the actual job title matter (Project Manager vs Scrum Master) when looking for new jobs in the PM space ? 

*I am trying to ascertain if taking up the Iteration manager for the benefits it offers (eg: immediate job offer, e-commerce experience) will hurt my chances of progressing along the project/program manager track (which I am currently on)* 

Feedback will be much appreciated from Recruiters/Hiring Managers/Fellow PMs/Scrum Masters.
