How is splunk for career?

I have been offered a backend senior software engineer role at splunk and might have to make a decision soon. Haven't discussed the numbers yet. I was wondering in general, is splunk considered a good company? And how is it career wise? I am a general backend swe. If I go into splunk, do you think later on I will have to limit myself in to logging, monitoring and apm domain? By going through blind threads it seems, splunk has good culture. People I interviewed with seemed nice too. Do you think company like amazon might be better career wise? More to learn and exit options are better? The only reason I haven't interviewed with them is because of the high probability of ending up in a bad team and what I have read here on blind. IBM Tc: ~140 Background: Master's with ~7 yoe
