AI Principal Engineer / Architect
SEON is the command center for fraud prevention and AML compliance helping thousands of companies worldwide stop fraud reduce risk and protect revenue. Powered by 900 real-time first-party data signals SEON enriches customer profiles flags suspicious behavior and streamlines compliance workflows - all from one place. SEON provides richer data more flexible and transparent analysis and faster time to value than any other provider on the market. Weve helped companies reduce fraud by 95% and achieve 32x ROI and were growing fast thanks to our partnerships with some of the worlds most ambitious digital brands like Revolut Wise and Bilt.
We are looking for an exceptional AI Principal Engineer / Architect to guide the evolution of SEONs AI and ML architecture. You will serve as the technical visionary and hands-on leader for our AI strategy setting direction for model lifecycle management infrastructure design and cross-functional integrations with product platform and engineering.
This role is critical in ensuring that SEONs fraud detection models remain cutting-edge scalable and deeply integrated into our core systems. You will work across domains from real-time inference pipelines and feature stores to advanced anomaly detection and LLM-enabled risk workflows helping us push the boundaries of whats possible in digital fraud prevention.
This role offers flexibility and can be based remotely in the EU.
What Youll Do
- Architect and Scale AI Systems: Design the foundational architecture for GenAI-powered fraud detection from prompt pipelines and embeddings to real-time enrichment and scoring services.
- Lead GenAI Product Integration: Partner with product and engineering teams to build and launch features that leverage LLMs and generative techniques to detect fraud signals surface insights and enhance user workflows.
- Develop Reusable Components: Build reusable infrastructure and SDKs for LLM integration prompt templating retrieval-augmented generation (RAG) and online feature inference.
- Own AI Infrastructure: Define patterns and tooling for model lifecycle experimentation evaluation versioning deployment and monitoring using an AWS-native stack (e.g. SageMaker BedRock etc.).
- Embed AI in the Platform: Drive seamless integration of generative and traditional ML capabilities into SEONs core SaaS product with a focus on real-time responsiveness and usability.
- Collaborate Cross-Functionally: Act as a trusted technical partner to product managers fraud experts and customer-facing teams shaping the roadmap for AI-first product features.
- Champion Engineering Standards: Set the bar for high-quality reliable AI systems through testing CI/CD integration data validation and observability practices.

What You Bring
- Generative AI Experience: Solid understanding of LLM architecture prompt engineering embeddings vector search (e.g. FAISS pgvector) and GenAI product patterns like RAG or tool use.
- Product-Oriented Mindset: A strong belief that AI is only valuable when it solves real user problems with a bias toward simplicity reliability and performance.
- ML & Engineering Expertise: 8 years of experience building AI/ML systems at scale ideally in a SaaS B2B or data-heavy product environment.
- AWS-Native Thinking: Proficiency in designing AI/ML infrastructure on AWS (SageMaker S3 Lambda API Gateway Step Functions etc.).
- System Design Strength: Ability to define architecture that balances latency scale experimentation and cost with a deep understanding of distributed systems.
- Full-Stack AI Lifecycle: Familiarity with the end-to-end AI development process from prototyping and evaluation to deployment and monitoring.
- Collaboration and Leadership: Experience working cross-functionally and mentoring other engineers or data scientists to deliver AI features that make it to production.
- Fraud Risk or Fintech Curiosity (a plus): Experience in domains like fraud detection fintech transaction monitoring or security is a bonus but a sharp learning curve is just as welcome.
- Masters or PhD - Data Science is preferable.
