Senior Software Developer

Role Overview

• Implement Core Application Services (C#) by building and maintaining C# Lambda functions, background workers, and microservices that integrate with queues such as SQS.
• Develop data ingestion endpoints and backend services consumed by internal and external APIs.
• Implement retry, failure handling, and idempotency logic across queue-based workflows.
• Develop and Maintain ETL Processing Pipelines (Python in AWS Glue) by writing Python ETL jobs in Glue for data extraction, transformation, and loading into reporting or downstream systems.
• Work with structured and semi-structured data formats (JSON, CSV, Parquet).
• Optimize Glue jobs for performance, cost efficiency, and reliability.
• Work Across an Event-Driven Architecture by implementing components that interact with SQS queues, Lambda functions, and internal processing clusters.
• Ensure data flows reliably from ingestion to transformation to downstream reporting.
• Build mechanisms to correct, reprocess, or quarantine problematic data.
• Build Secure, Scalable API Integrations by implementing REST endpoints behind API Gateway and integrate with Cognito/SSO authentication.
