How to jobify this?

Code (CSharp):

1. protected override void OnUpdate()
2.     {
3.         var dt = Time.deltaTime;
4.  
5.         Entities.ForEach((BonesContainer BC, ref PoserV2 Poser, ref LocalVelocity Velocity, ref IsVisible IsVisible) =>
6. {
7.     if (IsVisible.Value == true)
8.     {
9.         //check for pose and switch if necessary
10.         Pose currentPose = PoseManager.Poses[Poser.CurrentPoseId];
11.         Pose idealPose = PoseManager.GetNearest(Velocity.Value);
12.  
13.         //If ideal pose is not the current pose, and currentPose is not the transition of the ideal pose
14.         if (idealPose.Id != currentPose.Id && idealPose.TransitionId != currentPose.Id)
15.         {
16.             Poser.CurrentPoseId = idealPose.Id;
17.             Poser.isAnimating = true;
18.         }
19.         else
20.         {
21.             if (Poser.isAnimating)
22.             {
23.                 bool ready = true;
24.  
25.                 for (int i = 0; i < BC.Bones.Length; i++)
26.                 {
27.                     BC.Bones[i].localRotation = math.slerp(BC.Bones[i].localRotation, currentPose.Rotations[i], currentPose.Speed * dt);
28.  
29.                     float angle = Quaternion.Angle(BC.Bones[i].localRotation, currentPose.Rotations[i]);
30.                     if (angle > currentPose.Window) ready = false;
31.                 }
32.  
33.                 if (ready)
34.                 {
35.                     Poser.isAnimating = false;
36.                     if (currentPose.TransitionId != -1)
37.                     {
38.                         Pose trans = PoseManager.Poses[currentPose.TransitionId];
39.                         if (idealPose.Id == trans.Id || idealPose.Id == trans.TransitionId)
40.                         {
41.                             Poser.CurrentPoseId = trans.Id;
42.                             Poser.isAnimating = true;
43.                         }
44.                     }
45.                 }
46.  
47.             }
48.         }
49.  
50.     }
51.  
52. });

I have a simple animation system that is done using the hybrid approach.
1. I collect pose data from monobehaviour "skeletons", which I can edit in the editor view. These are saved into a static class which the systems then can access to find pose data
2. I store the animators state inside a Poser IComponentData

My problem is, that I can't really come up with a smart way to store the Animators bone transforms that need to be rotated according to the ideal pose. Currently I'm using a MonoBehaviour that collects all child transforms in the start.

The performance is allright at the moment, and making new poses is very easy - but I'd really like to Jobify it. The biggest performance eater I've discovered seem to the this part

Code (CSharp):

1.                 for (int i = 0; i < BC.Bones.Length; i++)
2.                 {
3.                     BC.Bones[i].localRotation = math.slerp(BC.Bones[i].localRotation, currentPose.Rotations[i], currentPose.Speed * dt);
4.  
5.                     float angle = Quaternion.Angle(BC.Bones[i].localRotation, currentPose.Rotations[i]);
6.                     if (angle > currentPose.Window) ready = false;
7.                 }

Do you have any suggestions of re-factoring or authoring data in a way that it is more ECS friendly / performant? Even if it is for a small part of the logic?
