We are bsport. The place to be!

bsport is an all-in-one platform combining boutique fitness and advanced technology. Our platform helps partners manage their bookings, payroll, marketing and more, to streamline operations and boost their commercial success.

🎯 What you’ll own & the role

Build Security from the ground up!!

We're looking for a hands-on Senior Security Engineer who will be the driving force behind bsport's security transformation.

This role is critical because:

• You'll directly protect ~10 million users' personal data.

• You'll enable our sales team to confidently answer security questionnaires as we pursue enterprise clients.

• You’ll work in the SRE team, with close collaboration with SWE teams and exposure to most if not all department leaders.

• You'll reduce business risk in a fast-scaling environment where security incidents can damage trust and revenue.
