About the squad: PCA x SIO

Our product organisation is built around verticals. This squad covers two of them.

PCA (Profitable Connected Assets): everything that happens once a charger is installed and connected. Commissioning and connectivity reliability, session data, the driver apps, billing of sessions and subscriptions, integration with CPO platforms like Ampeco and be.energised, SEPA and ad-hoc payments, Advenir subsidy flows, and the value-added services we sell on the connected fleet.

SIO (Streamlined Internal Operations): the systems our own teams run on. Purchasing and supplier flows, logistics and stock management, plus the customer support and administration tooling used by our teams across 8 countries.

Both verticals run on the same core platform, which is why they share one squad.
