Job description: Chief Technology Officer

To make Funxtion scalable, a lot needs to be done behind the scenes – especially when it comes to building the IT team and architecture. This will be the Chief Technology Officer’s responsibility.

Funxtion still heavily relies on third-party services. To enable their ambitious growth, bringing all core technology in-house is key. For example, API and SDK development, as well as DevOps/Cloud engineering, will be in scope in this transition. To achieve this, the IT team is envisioned to grow from its current eleven members to almost thirty next year, with another doubling in size in the three years thereafter. The CTO will oversee the talent acquisition for all necessary capabilities.

The CTO will also set up the Data Science capability from scratch. Deep learning and machine learning are on the roadmap to be incorporated into Funxtion’s organization. This will allow for further personalization of clients’ content and ultimately, members’ fitness journey.

“With a clear roadmap, a proven product, and the budget for growth, this is an excellent moment for a CTO to join Funxtion. If you are excited by ensuring scalability while maintaining our innovative edge, this role is the perfect challenge.” – Mendel Witzenhausen, Co-founder Funxtion

The CTO will rely on their technical background to drive innovation, while taking pride in nurturing company and team culture with a strong focus on the personal and professional growth of team members. The team will be divided into multiple functional development squads that need to be in sync, without losing agility or speed. The CTO will take charge of this transformation, building the squads based on sensible organizational design choices that fit with Funxtion’s IT and product strategy.

The CTO will contribute to Funxtion’s strategy through their invaluable perspective on product and IT, in discussions with the co-founders and board. They will also be able to understand and discuss code and processes. This is an ideal role for someone with experience as a developer or solution architect and several years’ worth of expertise in growing a young company through leadership and strategic decision-making preferably in a multi-client or white-label environment.
