FOSS and Security experience in South Africa? Who are you?

Dear Lazyweb,

The company that I work for, Exponant, is currently looking for skills in Information Security and FOSS (Free and Open Source Software).
If you are an experienced professional in the above areas I would love to hear from you.

On the security side we are looking for senior engineers and architects.
On the FOSS side we are looking for individuals with experience with FOSS in the enterprise.

We are based in Centurion, South Africa and most our demand is from clients in Pretoria.
