Come and be yourself with us
Being a Bobber is all about being you. We want you to bring all parts of yourself to work, giving you the freedom and confidence to be the best you and do your best work. If that is bubbly, shy, precise, funny, bold, kind, honest, brilliant, or anything in between, we are waiting with open arms. About the role
We are looking for an experienced Lead Customer Success Manager to join our Enterprise Customer Success team and own a small portfolio of HiBob’s largest and most complex customers.
This is an individual contributor role, not a people manager position. It sits above the current Senior CSM level and is designed for someone who can operate strategically with enterprise customers, executive stakeholders and internal senior partners. You will typically own around five strategic accounts, with a much smaller book than a standard Enterprise CSM, and you will spend your time on customer strategy, retention, expansion and cross-functional coordination.
Every day will be different. Some conversations will be about growth and opportunity, while others will involve navigating complexity, managing escalations, aligning multiple stakeholders or bringing in the right internal experts to move things forward. If you enjoy working with large customers, solving complicated problems and acting as a trusted advisor, we would love to hear from you. Requirements are often considered a measure of how equipped you are to do the job, but sometimes they are not the only factor. If you do not meet every requirement listed below but believe you would be successful in the role, we would still love to hear from you.
