Interim Chief Product Officer

Job description

At Karos, our mission is to make short-distance carpooling a new form of public transport.

We are entering a particularly exciting chapter. The acquisition of BlablaCar Daily gives us the opportunity to join forces to build a stronger, unified platform. At the same time, growing momentum in France and internationally is pushing us to rethink our market fit and how deeply our solution can integrate with cities and public transport networks.

Meanwhile, AI is transforming how product organisations operate - from discovery and delivery to design and user support.

To lead Karos through this pivotal period, we are looking for an Interim Chief Product Officer to cover maternity leave from January to August 2027 (with some handover time to be planned in December 2026 & September 2027).

In this role, you will join the Executive Committee and take ownership of major strategic decisions, team development and product performance in a key transitional period for the company. You will lead a multidisciplinary team spanning across Product Management and Design primarily but also managing the User Support lead. Working as a close CPO-CTO duo with Tristan Croiset, our CTO, you will set the vision, priorities and cadence of the Product & Engineering organisation.

Your scope

Your mandate will focus on four priorities:

• Shape our offering: Complete the Daily migration, turn the acquisition’s learnings into a stronger unified platform, and guide strategic product decisions for major opportunities in France and internationally.

• Grow the team: Coach team members and define the right organisation following the Daily integration, and ensure teams remain focused on high-impact outcomes.

• Transform our practices with AI: Help Product Managers and Designers use AI to work faster and better, improve operational efficiency and support internationalisation.

• Drive product impact: Lead OKR planning, maintain a strong review rhythm and continuously align priorities, delivery and measurable outcomes with the CTO and Executive Committee.

Location: Paris

Contract period: January-August 2027
