Narrative:

Departing from runway 32 out of ZZZ; we experienced an RA (resolution advisory) due to close proximity traffic. Lining up on runway 32 after tower had just opened; we were cleared for takeoff with an assigned altitude of 2000 ft and runway heading. I and the tower had visual contact with a single engine cessna that had just departed prior to us taking the runway. It appeared to be turning to the right of the runway centerline. On takeoff roll the tower changed our heading instructions to a left turn 280 in order to maintain separation from that traffic. The tower did note that he was not talking to the cessna ahead of us. We executed a left turn to 280 after takeoff and nearing 2000 feet; the tower instructed us to make a 'hard right turn to heading 360 and climb to 10;000 ft;' as pm (pilot monitoring) I read back those instructions; however; knowing the cessna traffic's location; the captain and I were concerned about executing a right turn in the direction of the traffic. Within seconds of that instruction to turn right and climb; we received a traffic warning from the TCAS (traffic collision avoidance system) systems and within a split second and RA was announced by the TCAS system. The captain; who was acting as PF (pilot flying) disengaged the autopilot and started a climb to avoid the traffic and comply with the resolution advisory. As we were climbing above 2000 ft; I acquired visual of the cessna and noted it was not more than 300 to 400 feet below us as we were climbing. At this point we were still on a 280 heading. After clearing the conflict; we turned on course continuing the climb to 10;000ft and contacted departure. A single engine cessna departure ZZZ and was not in communications with tower. He appeared to be turning east. We took off and the traffic turned west towards us. We followed SOP (standard operating procedure) guidance and cfm (company flight manual) procedures following the TCAS systems to avoid a mid-air. The cessna aircraft should have been in direct radio contact with the tower. Tower should have directed us to continue our turn to the west instead of the east while climbing.
