Job Description

We are building a next‑generation, business‑centric data intelligence and AI foundation that fuels Finance—from FP&A intelligence to product, compliance, and controllership decision‑making. As a Data Engineer of the Finance Technology – Data Intelligence organization, you will architect scalable data pipelines, semantic models, and end‑to‑end BI solutions, while safely operationalizing GenAI capabilities such as RAG, prompt engineering, evaluation frameworks, and agent‑based workflows. You will collaborate closely with analysts, data scientists, and engineering partners to deliver secure, reliable, auditable, and reusable data and AI services that materially enhance decision quality, automation, and speed across Finance.

Responsibilities:

Build the data foundation

• Collaborate with Data Analysts, Data Scientists, Software Engineers, and cross-functional partners to design, build, and deploy scalable data pipelines that deliver high‑quality, governed analytical datasets across Finance domains.

• Engineer high‑quality batch/streaming data pipelines (SQL/Hive/Py Spark) across Lake/Lakehouse to power curated finance domain marts and a governed semantic layer.

• Design dimensional/semantic models that enable self‑service analytics (Power BI / Fabric semantic models / SSAS Tabular) with performant DAX measures and row‑level security.

Operationalize Gen AI for Finance

• Ship production‑grade Gen AI features (retrieval‑augmented generation, prompt‑chaining/agents) on governed datasets - implement vectorization strategies and chunking that respect PII/SOX controls.

• Partner with DS/ML to train/fine‑tune and evaluate models - harden prompt templates, guardrails, and content filters - track hallucination, toxicity, and retrieval metrics (precision/recall, hit@k).

• Build reusable components (prompt libraries, evaluation harnesses, vector store abstractions) and integration SDKs/APIs for reuse across Finance use cases.

Platform, reliability & DevOps

• Implement CI/CD for data & AI (Git, Azure DevOps/GitHub Actions), data quality tests (Great Expectations or equivalent), and model/data deployment automation (MLflow/Fabric/Azure ML).

• Define observability (lineage, drift, freshness, cost) with alerts/SLAs - drive continuous hardening for performance (SQL/DAX tuning), cost efficiency, and reliability.

Analytics enablement

• Deliver high‑impact dashboards/scorecards (Power BI/Tableau) and governed certified datasets - coach analysts on best‑practice modeling and performance tuning.

Risk, governance & documentation

• Embed privacy‑by‑design (PII masking, purpose limitation), finance controls (SOX, audit trails), and robust documentation (runbooks, data dictionaries, model cards).

This is a hybrid position. Expectation of days in the office will be confirmed by your Hiring Manager.

Qualifications

Basic Qualifications:

• Bachelor's degree, OR 3+ years of relevant work experience

Preferred Qualifications:

• Bachelor's degree, OR 3+ years of relevant work experience
• Bachelors degree in Engineering with Honors in Data Science or Computer Science is required, along with 1+ years of hands-on experience building large scale data processing platforms
• Strong understanding of data warehousing concepts, including ER data modeling, data warehouse architecture, feature engineering, and solid knowledge of the Big Data ecosystem and its 5 Vs.
• 1+ years of practical experience using SQL/Hive/Py Spark for data extraction, aggregation, optimization, and storage on Hadoop technologies (Spark, Tez, MR) and cloud platforms
• 1+ years of applied GenAI engineering experience, including production grade GenAI features such as RAG over enterprise data, prompt engineering, evaluation, guardrails, and familiarity with LLMs, vectorization, chunking, and orchestration frameworks (Lang Chain).
• Ability to build reusable components—including prompt libraries, evaluation frameworks, vector store abstractions—and integration SDKs/APIs to enable reuse across Finance scenarios.
• 1+ years of hands-on experience delivering end to end Business Intelligence solutions, with an understanding of ETL strategies and the ability to contribute to data model decisions for reporting.
• Working knowledge of Machine Learning, Deep Learning, GenAI, and MLOps is a strong advantage.
• Familiarity with Data administration (YARN, Splunk, Profiler, Perfmon, security architecture, user provisioning, audit, etc.) is preferred.
• Exposure to Finance Data Analytics or finance domain is an added advantage.
