Overview of role
Working in the B2B Team at ONE FIIT, you will be joining the team to support the growth of our commercial function across a range of different industries such as Gyms, Corporates, Residential, Hotels and Wellness. You will be working with some of our biggest client partners, and will work with our business development team to help drive and optimise the sales funnel.

Role responsibilities
Pre sales

• Sales support - Support sales process by helping book meetings, draft follow up emails + organise calls, managing trial accounts, chase prospects, building out named account lists and database management
• B2B Marketing - Working with Product and Marketing teams; write proposals, pitches, case studies, product docs and CRM + nurture campaigns.

Key skills and experience
We are looking for someone with 3-4 years experience of working in account management, project management or sales type roles. They need to have high energy and a can-do attitude and thrive in fast paced, startup environments. Being able to manage multiple workstreams and being adept at multitasking is critical.

Although the role is commercially focused so a passion for business development is important (like helping win new customers, renewing & expanding existing partners), we are looking for someone who is a strong project manager with good organisational skills, great time management and loves getting into the details (as well as get things done at pace).

We need someone who is a great communicator, problem solver and has a growth mindset. We are looking for someone who occasionally doesn't mind getting thrown into the deep end.

At ONE FIIT we are using technology to make fitness a lifelong habit for everybody, so having passion for fitness and a good understanding of how technology can impact people's lives in a positive way is a big plus.
