About the Role

We’re hiring a Senior AWS Serverless Developer to join a greenfield project building a modern, event-driven data platform for regulatory and compliance reporting.

You’ll design and develop a decoupled middleware layer that ingests data from multiple sources, transforms it, and routes it to 25+ downstream systems. This is a backend-heavy role where event-driven workflows power everything—from API triggers to S3-driven pipelines.

• Build and orchestrate serverless, event-driven architectures on AWS
• Develop scalable solutions using Lambda, Step Functions, Glue, and S3
• Design data pipelines to ingest, enrich, and transform data
• Integrate systems via EventBridge, SNS, SQS, and API Gateway
• Implement Infrastructure as Code (CDK or SAM) and CI/CD via Azure DevOps
• Collaborate with technical and delivery teams to ensure data integrity and reliability

✅ What We’re Looking For

• Strong experience with AWS Serverless (Lambda, Step Functions, S3, Glue)
• Expertise in Python for cloud-native development
• Proven experience building event-driven architectures
• Hands-on with CI/CD pipelines and Infrastructure as Code
• Experience integrating data from APIs, files, and messaging systems

⭐ Nice to Have

• Greenfield project experience
• Exposure to regulatory, compliance, or trading data

Who You Are

• A self-starter who thrives in fast-moving environments
• Strong communicator who can bridge technical and business teams
• Passionate about clean, maintainable code
• Enjoy mentoring and supporting other developers
