across full-stack development, data engineering, and AI/ML projects. We empower clients by

combining deep technical expertise with a commitment to agility and quality, enabling ambitious digital

transformation.

Role Summary We are seeking a hands-on Senior Data Engineer having 4 to 7 years of experience on AWS. The project

centers on a data lakehouse platform that ingests data from heterogeneous sources, organizes it

through semantic layers, exposes it via REST APIs, and is being enhanced with AI-powered natural

language query capabilities and entity resolution.

The ideal candidate brings strong experience with at least one modern data lakehouse, data

warehouse, or data mesh platform (e.g., Databricks, Snowflake, Dremio, Apache Iceberg/Trino, or

similar) and can apply that expertise to build robust data pipelines, implement semantic layers,

develop APIs, has implemented dbt transformation, and contribute to AI-enhanced data capabilities on

AWS.

Key Responsibilities

• Design, develop, and maintain REST APIs (Flask, FastAPI, or similar) that enable read access to

the application layer with appropriate transformations for diverse consumer needs.

• Collaborate on the development of AI-powered natural language query capabilities: contribute

to data catalog and data dictionary development, support integration with LLM services (Cursor

or similar), validate response accuracy, and build guardrails and Eval frameworks.

• Design and implement data ingestion pipelines from heterogeneous sources (SQL Server,

MySQL, PostgreSQL, Oracle, Solr, Elasticsearch) using native platform connectors where

available and custom Python-based ETL/ELT pipelines where not.

• Develop and maintain ingestion workflows that stage data in cloud object storage (S3) and

integrate with the data lakehouse platform.

• Build and maintain semantic layers (raw staging/bronze, business/silver, application/gold)

ensuring data quality, lineage, and optimization for consumption.

• Implement reflections, materializations, or virtual datasets to optimize query performance and

enable efficient data access patterns.

• Collaborate with data scientists, analytics teams, and stakeholders to understand requirements

and deliver scalable, reliable data solutions.

• Participate in code reviews, document technical designs, and contribute to a culture of

engineering excellence.

Required Skills And Qualifications

• Experience building REST APIs using Python frameworks (Flask, FastAPI, or similar) with

transformation logic for data consumers.

• Proficiency in Python for data pipeline development, ETL/ELT workflows, and automation

scripting.

• Hands-on data engineering experience with proven expertise in building production-grade data

pipelines and systems.

• Hands-on experience with at least one modern data lakehouse, data warehouse, or data mesh

platform (e.g., Databricks, Snowflake, Dremio, Trino/Presto, Apache Iceberg, Delta Lake, or

similar) with understanding of semantic/virtual layers and query optimization.

• Hands-on experience with dbt or a similar ELT automation platform, including model

development, testing, documentation, and deployment of transformation pipelines.

• Experience building, managing, and monitoring data workflows with Apache Airflow or a similar

orchestration tool, including scheduling, dependency management, failure handling, and

operational monitoring.

services).

• Strong SQL skills across multiple database dialects (SQL Server, MySQL, PostgreSQL, Oracle)

with experience in query optimization and performance tuning.

• Familiarity with data modeling, dimensional modeling, and semantic layer design patterns.
• Experience with version control (Git), CI/CD pipelines, and DevOps practices in cloud

environments.

• Strong problem-solving skills with ability to troubleshoot complex data pipeline issues and

optimize performance.
