How can I get a component data from an entity inside a JobComponentSystem?

I had this system as an ECS, now I am trying to convert it to a job system. My issue is I was using

 World.DefaultGameObjectInjectionWorld.EntityManager.GetComponentData<Translation>( hasTarget.targetEntity );

But this does not work inside of JobSystem. I am new to this and would appreciate any help. Since this job runs on multiple entities, I am unsure of how to pass multiple Translation data to the job and I dont understand how the job will know which Translation data corresponds to each entity.

 public class UnitMoveToTargetJobSystem : JobComponentSystem
 {
     //[ RequireComponentTag( typeof( HasTarget ) ) ]
     [ ExcludeComponent( typeof( InCombat ) ) ]
     [ BurstCompile ]
     private struct MoveToTargetJob : IJobForEachWithEntity<HasTarget , Translation>
     {
         public EntityCommandBuffer.Concurrent entityCommandBuffer;
         public float dt;
         public bool entityHasTarget;
 
         public void Execute( Entity unitEntity , int index , ref HasTarget hasTarget , ref Translation translation )
         {
             if ( hasTarget.targetEntity != null )
             {
                 Translation targetTranslation = World.DefaultGameObjectInjectionWorld.EntityManager.GetComponentData<Translation>( hasTarget.targetEntity );
 
                 float3 targetDirection = math.normalize( targetTranslation.Value - translation.Value );
                 float moveSpeed = 8f;
                 translation.Value += targetDirection * moveSpeed * dt;
 
                 if ( math.distance( translation.Value , targetTranslation.Value ) <= 0.3f )
                 {
                     entityCommandBuffer.AddComponent( index , unitEntity , new InCombat { enemy = hasTarget.targetEntity } );
                     entityCommandBuffer.RemoveComponent( index , unitEntity , typeof( HasTarget ) );
 
                     //PostUpdateCommands.AddComponent( unitEntity , new InCombat { enemy = hasTarget.targetEntity } );
                     //PostUpdateCommands.RemoveComponent( unitEntity , typeof( HasTarget ) );
                 }
             }
             else
             {
                 entityCommandBuffer.RemoveComponent( index , unitEntity , typeof( HasTarget ) );
 
                 //PostUpdateCommands.RemoveComponent( unitEntity , typeof( HasTarget ) );
             }
         }
     }
 
     private EndSimulationEntityCommandBufferSystem endSimulationEntityCommandBufferSystem;
     protected override void OnCreate()
     {
         endSimulationEntityCommandBufferSystem = World.GetOrCreateSystem<EndSimulationEntityCommandBufferSystem>();
         base.OnCreate();
     }
 
     protected override JobHandle OnUpdate( JobHandle inputDeps )
     {
         MoveToTargetJob moveToTargetJob = new MoveToTargetJob
         {
             entityCommandBuffer = endSimulationEntityCommandBufferSystem.CreateCommandBuffer().ToConcurrent() ,
             dt = Time.DeltaTime
         };
 
         JobHandle jobHandle = moveToTargetJob.Schedule( this , inputDeps );
         endSimulationEntityCommandBufferSystem.AddJobHandleForProducer( jobHandle );
 
         return jobHandle;
     }
