Job Overview

We are hiring a Mid-Level Data Engineer to design and build OLTP Online Transaction Processing systems and pipelines. This role focuses on transactional system design API driven data flows, and building reliable, high-performance data services. The ideal candidate thinks in terms of system architecture, transactional integrity, and low-latency data handling rather than scheduled data warehouse loads.

Key Responsibilities

• Design, build, and maintain OLTP pipelines for real-time or near real-time transactional data processing.
• Build and consume APIs to handle data ingestion updates and retrieval from operational systems.
• Design SQL Server database schemas optimized for transactional workloads, normalization, indexing, concurrency control, and locking behaviour.
• Write and optimize SQL queries, stored procedures, and transaction logic for high-throughput, low-latency operations.
• Ensure data consistency, atomicity, and integrity ACID compliance across services.
• Develop ETL processes as needed to support data migration, system integration, or occasional batch sync between transactional systems.
• Handle API request-response cycles, validation error handling, retries, and rate limiting on data write operations.
• Monitor system performance, diagnose issues such as deadlocks, query latency, and contention, and tune for scale.
• Deploy and manage data services using Azure SQL Database, API Management, and Azure Blob.
• Use SSIS SQL Server Integration Services for occasional data migration or integration tasks.
• Collaborate with backend engineers to integrate data layers into application services.
• Implement validation idempotency checks and integrity constraints at the transactional level.
• Create and maintain documentation for system architecture, API contracts, and database schemas.

Requirements

• Bachelor’s degree in Computer Science, Information Technology, or a related field or equivalent practical experience.
• 7 to 10 years of experience in SQL Server and relational database design for OLTP systems, normalization, indexing, transactions isolation levels.
• Solid experience building or consuming REST APIs for data read/write operations.
• Working knowledge of Azure services: Azure SQL Database, API Management, and Azure Blob Storage.
• Experience working with transactional data in high-concurrency production environments.
• Experience writing and optimizing SQL stored procedures for transactional systems.
• Hands-on experience with SSIS or similar tools for data migration integration tasks.
• Working knowledge of ETL development for occasional batch sync or migration needs.
• Understanding of system design fundamentals: concurrency, caching, request handling, and service scalability.
• Experience collaborating with backend application engineers to integrate data layers into services.
• Strong analytical, troubleshooting, and communication skills.
