CRM & User Lifecycle Manager Product Team (W/M/NB)

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

Helping users install lasting mobility habits is one of our strongest growth levers. We believe user engagement is not simply about sending messages—it’s about delivering the right experience to the right user at the right moment.

Over the last few years, we’ve built the foundations of a powerful lifecycle platform with Braze, event tracking and a clear lifecycle strategy. We’re now looking for someone who can turn these foundations into impactful user experiences.

As our CRM & User Lifecycle Manager, you will join the Product team and work closely with the User Engagement Product Manager. This is an individual-contributor role in which you will help design, build and continuously optimise the communication layer of the Karos user experience.

As part of the Product team at Karos, your responsibilities will include:

• CRM and marketing automation: Build, launch and maintain automated journeys in Braze across push notifications, in-app messages, email and SMS. Thoroughly test user journeys before launch, monitor their execution and maintain a consistently high level of quality across our lifecycle platform.

• Enablement & collaboration: Build & maintain ready-to-use documentation and good practices that make Product & Ops teams autonomous. Work closely with Product teams to make lifecycle communications part of the overall product experience.

• Lifecycle journey optimisation: Analyse user behaviour and identify communication opportunities or friction points across onboarding, activation, repeat usage, retention and reactivation. Turn these insights into improved user journeys leveraging behavioural segments and personalised experiences. Leverage AI to increase your efficiency and experimentation to design, launch and analyse A/B tests covering content, timing, channel, audience and journey structure.

• Performance analysis: Monitor activation, engagement and retention indicators, evaluate the impact of lifecycle initiatives and turn results into actionable recommendations.
