Are you seeking a dynamic position in security where you will positively impact both your peers and MailChimp customers? If so, you might be the right person to fill the Principal Security Engineer role on our team.

You can communicate effectively both upwards to our management team and across our engineering team. You love helping others balance the need to be secure with being pragmatic about getting features released to our customers.
