Chamber's Role

Cypher defends the site with his traps

Killjoy defends the site with her alarmbot and turret

Sage defends site with her slow orb and wall

Chamber defends the site with the Sniper and his trap.

Considering that, Chamber is just an aggressive Sentinel, his job is to defend the site with his abilities. (JUST LIKE other Sentinels)

Getting that many first blood is all about his site defense abilities. imo

I don't know why people even care about agent roles at this point. We've seen that most agents can act as another role if utilized correctly

I know this is pretty crazy, but the entire purpose of every agent on defense is to defend the site with their abilities
