Join us in making a difference

Our Marketing Solutions team is building an AI-first marketing engine that transforms messy, real-world data into autonomous, multichannel growth. We're not just building features—we're creating intelligent agents that research, reason, and execute across brand, paid, social, and CRM channels. As a Full-Stack Engineer, you'll be at the heart of this mission, turning ambitious ideas into production systems that drive measurable marketing impact.

This is your opportunity to own problems end-to-end, from architecture to pixel, and see your code ship to production within hours. You'll work in a high-agency environment where speed meets quality, and where your technical decisions directly influence how trivago reaches millions of travelers. If you're energized by autonomous systems, love the challenge of turning chaos into clarity, and want to build products that marketers love, this role will push you to grow in ways you didn't expect. Ready to make an impact? Let's build the future of marketing together!

Get an inside look at trivago's engineering culture:

How you’ll make an impact:

• Design and ship autonomous agent workflows that orchestrate research, decisioning, and multi-channel execution at scale
• Build robust data ingestion pipelines that transform millions of raw records from diverse sources into a reliable context layer for AI-driven personalization
• Develop customer-facing dashboards that translate complex AI operations into simple, actionable insights for marketing teams
• Own reliability and observability by implementing comprehensive logging, tracing, alerting, and performance budgets integrated into CI/CD
• Prototype and productionize rapidly, shipping agentic playbooks from concept to production in hours using lean experimentation and feature flags
• Close feedback loops by instrumenting end-to-end performance metrics and building self-optimizing systems that learn and improve continuously

What you'll need to thrive:

• Product-first thinking – you start from customer problems, define success metrics, and ship the smallest valuable solution before iterating
• Strong full-stack expertise in TypeScript/Node.js and React/Next.js, with comfort moving into APIs, data pipelines, and infrastructure when needed
• Hands-on experience with data and AI systems – familiarity with data pipelines (Postgres/BigQuery, Kafka), vector search, and agent/LLM frameworks (ai-sdk, LangChain, OpenAI, Anthropic)
• High agency and ownership mindset – you default to action, clarify ambiguity independently, and learn by shipping to production
• Operational excellence – you care deeply about SLAs, test coverage, observability, security, and cost efficiency
• Collaboration and communication skills – you thrive working with cross-functional stakeholders and can translate technical complexity into business value

Stand out with:

Nice to have: GCP (GKE/BigQuery/GCS), Python for data tasks, feature flagging/experimentation, growth/RevOps tooling, GDPR/CCPA awareness.
