About the Role:

As Technical Product Owner, you will be part of the Email competence center (TEM / Email Security) and work closely with the Technical Product Manager. Your mission is to translate the Email domain vision and roadmap into concrete, deliverable backlog items and to guide our development teams in implementing robust, scalable, secure and efficient Email services. You will help ensure that our Email products deliver high deliverability, strong protection and a reliable experience for enterprise customers with demanding communication and security requirements. You bring a strong software engineering background (ideally in backend, email infrastructure or security/communication platforms) and have grown into a Product Owner role. You are comfortable discussing architecture, performance, filtering and routing details with developers, while also understanding customer use cases, SLAs, compliance and operational constraints. You will sit at the intersection of product, security, operations and engineering: refining requirements, shaping epics and user stories, and ensuring that Email features and platform capabilities are implemented with high quality and are operable at scale.

• Strong experience with agile methods, sprint planning, backlog management and working as Product Owner in Scrum teams, including the ability to transform strategic direction and product requirements into structured epics, user stories and acceptance criteria.
• Solid understanding of email architectures and technologies (e.g. SMTP, MTAs, queues, routing, authentication standards, filtering pipelines), enabling you to have meaningful technical discussions with development and operations teams.
• Familiarity with SLAs, monitoring, high availability, incident management and security in production systems, and how these aspects should be reflected in backlog items and technical priorities.
• Strong analytical and problem‑solving skills; you can quickly grasp complex domain topics, operational constraints and technical dependencies.
