André Fernandes


Selling involves lots of different activities, a very important part of my work is to identify new clients and new business opportunities within the existing customer base. Being able to work for a dynamic company with a team that is looking to succeed and continuously evolve is very interesting. Even having a remote role, the relationship with my direct team is fantastic. We work in a very collaborative way, almost as if we were physically together.

Matt Dobbs


My main role is to purify raw materials to meet our final product specifications. I help Medix Biochemica in succeeding by ensuring quality product is produced in a reliable, repeatable, and well documented manner on time. The variation of different products I purify, and the various methods used for the targeted product purity make my job exciting.

Vincent Chen


I work for Medix Biochemica across China (including mainland, Hong kong, Taiwan and Macau), as well as being part of the global team. What energizes me about working here is being part of a team that's developing and constantly achieving.
