Hey everyone! 
@sam_ca is a Senior Backend Engineer and the Security Platform tech lead - so perfectly placed to discuss what steps we have in place as a bank to make sure that the right people have the right level of access.
For context, as a bank we run on thousands of microservices and these microservices communicate with each other using remote procedure calls (RPCs). Sometimes Monzo engineers need to use RPCs to communicate with a microservice.
Sam’s written a blog to detail, that with us constantly expanding these microservices we need to make this process secure - super detailed blog below 
In the blog, you’ll also see a few job openings if you want to jump on to Monzo:
Senior Backend Engineer - Security
Senior Engineering Manager - Security Engineering
Director of Engineering - Security Engineering
Sam is gonna pick up questions about the blog and his world if you have any
