Senior Software Engineer – Agentic AI (M/F/D)

Your mission

Help us make agentic AI a reliable part of how we create, manage, and deliver learning content at bettermarks. You’ll build agentic workflows and shared tools that support our content and engineering teams—from preparing and generating content to making it available reliably in our learning platform.

Your responsibilities:

• Build agentic content workflows: Develop solutions that support the preparation, generation, and organization of learning content, working closely with content experts to meet educational and quality requirements.
• Support content workflow management: Improve how content moves through creation, review, publication, and updates, with clear handovers, visible progress, and effective handling of exceptions.
• Enable scalable content delivery: Build and improve the services and processes that make learning content reliably available in the product, with attention to performance and the experience of teachers and students.
• Create shared AI tooling: Give teams the tools, context, and integrations they need to use agents effectively in their daily work, and help colleagues adopt useful approaches.
• Develop agentic delivery pipelines: Explore how agents can support software delivery, connecting agentic coding to CI/CD workflows, automated tests, and appropriate review.
• Make agent performance visible: Establish review, evaluation, and monitoring practices, and use the results to improve the reliability and quality of agentic workflows over time.
