Worker: Capsule Designer
The Capsule Designer focuses on ensuring that the system is able to respond to events in a timely manner, in accord with the concurrency requirements. The primary vehicle for solving these problems is the Artifact: Capsule.
Staffing 
The skills of the Capsule Designer are similar to that of the Worker:
Designer (the Capsule Designer is in fact a kind of Designer), but the
Capsule Designer requires more experience in dealing with concurrency issues.
The Capsule Designer must have a solid understanding of the types of problems
that surface in highly concurrent, reactive systems, as well as the various
approaches for addressing these problems. Required skills include an
understanding of the resource issues involved in creating, destroying and
synchronizing operating system processes and threads. In addition, the Capsule
Designer requires an understanding of handling state-dependent and event-driven
behavior in software systems.
