Customer Success Manager (CSM)

Upstream delivers a cloud-based, AI-powered behavioral intelligence platform for physical AI and smart mobility. Upstream empowers customers with advanced AI-driven cybersecurity solutions, including detection and response (XDR), AI Security, quality and operational intelligence, cyber threat Intel, SOC services, and more.

Upstream is seeking an experienced Customer Success Manager to join our EMEA team and lead high-touch enterprise relationships across automotive and mobility customers. This role reports to the Director of Customer Success EMEA, and works closely with cross-functional leaders across Sales, Product, Data, Research, Cyber, Delivery, and Ops.

This position combines strategic account ownership with hands-on technical execution and solution architecture. The CSM serves as the primary technical lead and main customer focal point, leading technical discovery and solution design, and guiding customers from the early engagement and PoV, through onboarding, production deployment, operationalization, and ongoing value delivery. You will engage both at the executive level and directly with technical and operational teams to ensure measurable business impact.

As we grow and scale, we are strengthening structure, accountability, and proactive account management across the region, while maintaining the agility and ownership mindset of a startup. This role will play a key part in driving that balance: bringing clarity, follow-through, and disciplined execution in complex, fast-moving environments.

Success in this role requires strong project management skills, technical fluency, value delivery and the ability to manage detailed day-to-day execution without losing sight of long-term strategy.

This role is full-time and based in Sweden, with a preference for the Gothenburg area.
