Temp Data Ai Jobs (NOW HIRING)

About the role

We are looking for a Senior Data & AI Architect to design, build, and manage the end-to-end data infrastructure that powers intelligent AI applications. In this role, you will act as a systems-oriented Senior Data & AI Architect for our clients. You are not just a developer writing code in isolation; you are a strategic thinker who bridges the gap between complex data networks and tangible business value—directly on-site with clients.

With a strong "Builder’s Mindset," you prioritize sustainable, scalable, and secure engineering over temporary quick fixes. You will bring this mindset into high-stakes, regulated environments (such as Financial Services and Med-Tech) where data quality, compliance, and governance are core product features, not administrative burdens.

Your responsibilities

• As a Senior Data & AI Architect, you will shape the data ecosystems of our clients and represent reeeliance’s architectural vision
• At this role, you will design and build the technical foundation for generative AI and machine learning workloads, including feature stores, vector databases (e.g., Pinecone, pgvector), embedding layers, and scalable ingestion pipelines
• Your role will be to define and implement robust modeling standards for structured, semi-structured, and unstructured data (utilizing Data Vault, dimensional modeling, and schema-on-read approaches)
• You will be responsible for structuring and conducting assessments to map a client’s data landscape, identify readiness gaps (schema quality, lineage, governance maturity) and establish reusable assessment frameworks
• You will treat regulatory requirements (e.g., EU AI Act, BCBS 239, GDPR, GxP) not as a burden, but as a technical feature, automate policies and security guardrails directly into CI/CD pipelines and platform provisioning
• In this role, you will champion the "Golden Path" philosophy, value clean architecture, automated testing, documentation, and total reproducibility (via Git, MLflow, and containerization) as non-negotiables, a hands‑on engineer who is as comfortable deep‑debugging a pipeline as you are designing high-level workflows
• As a Senior Data & AI Architect, you will act as a bilingual bridge, by explaining vector embeddings to a business executive and business ROI to a developer, listening first to understand the client’s problem before proposing technical solutions
• You will coach client teams and mentor junior colleagues at reeeliance, enabling them to adopt modern, high-quality data engineering practices and scaling our architectural mindset

Our requirements

• 5+ years of experience in data engineering, data architecture, or a related software engineering role
• Experience in or a strong interest in working within regulated sectors like Financial Services or Med-Tech, with an understanding of how regulatory standards shape data architectures
• Deep expertise in architecting and scaling solutions on Databricks, Snowflake, BigQuery, or similar modern cloud platforms
• High proficiency in Python and SQL, solid experience with transformation and orchestration tools (e.g., dbt, Apache Spark, Airflow, Prefect)
• Hands‑on experience building architectures for Large Language Models (LLMs) and Retrieval‑Augmented Generation (RAG), practical knowledge of vector databases (e.g., Pinecone, Weaviate, pgvector) and embedding management
• Solid understanding of MLOps patterns and tooling (e.g., MLflow, Kubeflow, SageMaker, or Vertex AI) to ensure models, code, and data versions are fully auditable and reproducible
• Proven ability to build systems focused on automated data quality, data lineage, metadata catalogs, and real‑time process monitoring
• Familiarity with decentralized data architectures, such as Data Mesh, and separating platform capabilities (Data Fabric) from domain data products
• Comfort with CI/CD tools, containerization (Docker, Kubernetes), and IaC (Terraform)
• A passion for understanding how tools work under the hood and proactively exploring emerging tech trends (e.g., transition from basic RAG to Agentic Reasoning)
• Strong consultative skills, empathy, and the ability to explain complex technical designs in plain language and experience in mentoring team members and helping them grow
• Articulate with impeccable verbal and written communication skills in German (C1 level) and English (B2 level). Strong & discerning listener
