The ideal candidate has a strong background in Azure data services, particularly Azure Cosmos DB and Azure Synapse Analytics, and has personally designed or taken architectural ownership of enterprise data solutions used by AI-powered applications.

Important: This is a Data Architecture role, not an AI/ML Engineering position. Hands-on development of RAG pipelines or AI agents is not required. The primary focus is designing scalable, reliable, AI-ready enterprise data architectures.

Key Responsibilities

• Design and own enterprise-scale data architectures within the Microsoft Azure ecosystem.
• Architect production-ready data platforms supporting GenAI, RAG, and Agentic AI applications.
• Design data ingestion, transformation, storage, and retrieval architectures for structured and unstructured enterprise data.
• Define AI-ready data architecture patterns, ensuring enterprise knowledge is accessible to AI-powered applications.
• Design and optimize solutions using Azure Cosmos DB, Azure Synapse Analytics, and related Azure data services.
• Develop scalable, metadata-driven and configuration-driven data ingestion frameworks.
• Design data models, lakehouse architectures, and enterprise data integration patterns.
• Lead architectural decisions related to data platform modernization, scalability, reliability, and performance.
• Ensure appropriate data governance, security, accessibility, and maintainability.
• Collaborate with engineering, AI, and business teams to align data architecture with application requirements.

Must-Have Requirements

• Strong expertise in enterprise Azure Data Architecture.
• Deep hands-on architectural experience with Azure Cosmos DB — mandatory.
• Strong experience with Azure Synapse Analytics.
• Proven experience designing production-ready data architectures for GenAI, RAG, or Agentic AI applications.
• Direct involvement in at least one real-world project where you designed or owned the data architecture supporting RAG, GenAI, or AI-agent applications.
• Demonstrated ability to independently design and take ownership of complex enterprise data architectures.
• Experience designing AI-ready data platforms, including data ingestion, preparation, storage, governance, and retrieval.
• Understanding of enterprise knowledge management and data accessibility requirements for AI applications.
• Experience working with structured and unstructured data.
• Strong data modeling, system integration, and architecture modernization skills.
• Experience designing scalable and reliable production data platforms.
• English B2+/C1.

Please note: Theoretical knowledge of RAG or Agentic AI is not sufficient. Candidates must demonstrate practical architectural experience and clearly explain their personal responsibilities and contributions to production projects.

Additional Technical Skills

• Azure Databricks
• Azure SQL Managed Instance / SQL Server / T-SQL
• Azure Data Lake Storage
• Lakehouse Architecture
• Azure Functions
• Metadata-driven and configuration-driven ingestion frameworks
• Enterprise data platform modernization
• Data governance and integration patterns
• Data retrieval and knowledge management architectures

What We Offer

• Fully remote collaboration from anywhere in the world (except Russia).
• Long-term, full-time engagement.
• Competitive hourly rate up to $30.

Project Description

A B2B marketing analytics platform for LinkedIn advertisers wants to know whether the early signals of an ad campaign can predict its outcome months ahead. Small B2B advertisers close only a handful of deals per year, so standard attribution has too little data to work with. The proof of concept tests a different approach on the platform's historical data across many advertisers. Engagement and website signals from the first 7-21 days of a campaign are combined into a surrogate index that predicts later pipeline outcomes and states how confident the prediction is.

The PoC is time-boxed to 5-6 weeks and ends with a Go or No-Go decision backed by numbers.

• A B2B marketing analytics platform for LinkedIn advertisers wants to know whether the early signals of an ad campaign can predict its outcome months ahead. Small B2B advertisers close only a handful of deals per year, so standard attribution has too little data to work with. The proof of concept tests a different approach on the platform's historical data across many advertisers. Engagement and website signals from the first 7-21 days of a campaign are combined into a surrogate index that predicts later pipeline outcomes and states how confident the prediction is.
   

Requirements:

• 5+ years of applied data science or statistics at a senior level.
• Strong command of regression modeling, including regularized and hierarchical (multilevel) models.
• Proven experience with small or sparse datasets and with probability calibration.
• Rigorous validation practice: temporal splits, leakage prevention, overfitting control.
• Python (pandas, scikit-learn, statsmodels) and SQL.
• Ability to explain uncertainty to non-technical stakeholders.
• English - upper-intermediate.

Nice to have

• Bayesian tooling such as PyMC, Stan or bambi.

  5-6 weeks, starting in October 2026, exact date to be confirmed.
• Possible continuation into productization if the PoC succeeds.

Responsibilities:

• Define, together with the client and a business analyst, what counts as campaign success, the outcome window and the cut-off between signals and outcome.
• Design the analytical dataset: candidate signals, outcome labels, exclusion rules and safeguards against future information leaking into the signals. A Python data engineer builds the dataset in ClickHouse to this design.
• Build the surrogate index as a regularized or hierarchical model, with signal weights shared across advertisers and adjusted per advertiser in proportion to its own data volume.
• Validate the model on campaigns it has not seen: temporal backtesting and leave-one-advertiser-out evaluation, with AUC, Brier score and calibration curves.
• Compare the model against the current practice of judging campaigns by CTR and CPC, and measure how prediction quality changes between day 14 and 21.
• Run error analysis, source ablation and learning curves to show which data is missing for a reliable forecast.
• Present weights, patterns and uncertainty to the team and reccomend Go or No-Go for the future phase.

- Assess an existing Azure data platform, separate quick tactical fixes from the long-term target architecture, and drive both forward
- Deliver implementation-ready architecture: documentation, diagrams and recommendations that engineering teams can act on, with first results within 1-2 weeks
- Design the data and knowledge layer for RAG and Agentic AI applications
- Design scalable metadata/configuration-driven ingestion for databases, APIs and file-based sources
- Make technology-neutral decisions on when Synapse, Databricks, ADF, Azure SQL or a Lakehouse are justified
