How good is the Multi-Asset Strategies team at BR?

Have an offer from them but unclear whether the exit opps are decent. It's a PM role which would be split down the middle between

1) tactical asset allocation, custom portfolio construction, implementation, manage client flows, monitor risk, maybe portfolio optimisation, perf attribution, and working with the CIO, exposure SMAs/UCITS/ICAV structures

and

2) systematic active equity trading (not the SAE group), but designing signals on ESG, and adding/removing bespoke filters. Focusing on US large caps for now. Rather than focusing on pure alpha, would be lower cost and not explicitly targeting alpha as an outcome. Leveraging their Sustainability their research. Improving models using Python, optimisation, rebalancing, and building algos that allow automation of some PM processes. Been told that that is the fastest growing part of their business? 

Also the comp is really low to what I expected (this is BR London though). For a mid-year associate about 140k all-in USD equivalent... (25-30% bonus).

Are other groups more lucrative?

Is the group decent? What would a pivot to say, an AQR type of shop or even a HF look like if possible on the systematic equities side?
