About the Role

Jobgether is hiring an AI Principal Engineer / Architect to lead the design and implementation of advanced AI systems for real-time decision-making in high-stakes environments. You will shape our AI strategy, drive model development, and ensure seamless integration of AI capabilities across product and platform teams.

What You'll Do

  • Architect and scale AI/ML systems for real-time and generative use cases, including embeddings, prompt pipelines, feature stores, and inference services.
  • Partner with product and engineering teams to integrate AI capabilities into workflows that detect fraud and surface actionable insights.
  • Develop reusable infrastructure, SDKs, and pipelines for LLM integration, prompt templating, and retrieval-augmented generation (RAG).
  • Define AI infrastructure standards, including model lifecycle management, versioning, deployment, monitoring, and CI/CD best practices.
  • Collaborate cross-functionally with product managers, engineers, and domain experts to shape AI-first features and ensure alignment with business goals.
  • Explore and prototype emerging AI tools, open-source models, and vector store technologies to test real-world applicability.
  • Champion engineering standards for reliable, testable, and observable AI systems.

What We're Looking For

  • 8+ years of experience building scalable AI/ML systems, preferably in SaaS, B2B, or data-intensive environments.
  • Strong knowledge of generative AI, LLMs, prompt engineering, embeddings, vector search technologies (e.g., FAISS, pgvector), and RAG workflows.
  • Expertise in AWS-native AI/ML infrastructure (SageMaker, S3, Lambda, Step Functions, API Gateway).
  • Proven system design skills, balancing latency, scalability, experimentation, and cost.
  • Familiarity with the full AI lifecycle: prototyping, evaluation, deployment, monitoring, and optimization.
  • Experience leading cross-functional teams and mentoring engineers or data scientists.
  • Product-oriented mindset: ability to translate AI capabilities into solutions that deliver real user value.

Nice to Have

  • Advanced degree (Masters or PhD) in Data Science, Computer Science, or a related field.
  • Experience in fraud detection, fintech, risk management, or security domains.

Technical Stack

  • AWS: SageMaker, S3, Lambda, Step Functions, API Gateway
  • Vector Technologies: FAISS, pgvector

Team & Environment

You will collaborate closely with product and engineering teams in a collaborative and innovative culture with global impact.

Benefits & Compensation

  • Competitive salary with performance-based opportunities.
  • Flexible working arrangements and fully remote position within the EU.
  • Professional development support including courses, conferences, and certifications.
  • Opportunity to work with advanced AI technologies in a fast-growing, high-impact environment.
  • Influence strategic AI and product decisions at scale.
