About the Role

We are looking for an experienced Senior AWS Integration Developer to design, build, migrate, and support enterprise integrations using AWS serverless and integration services.

This is not an AWS DevOps role and not a general-purpose cloud developer position. The ideal candidate must have hands-on experience building integrations from scratch between enterprise applications, APIs, third-party systems, and cloud services.

The team is modernizing an existing enterprise integration landscape currently running on IBM DataPower and IBM App Connect Enterprise (ACE) and migrating integrations to AWS. Strong AWS integration experience is mandatory; prior IBM DataPower/ACE experience is useful but not required.

The role is part of a global enterprise team and requires strong communication because the engineer will collaborate with stakeholders and technical teams across India, the US, and UK.

What You'll Do

- Design and develop cloud-native enterprise integrations using:
- AWS API Gateway
- AWS Lambda
- Python
- Amazon EventBridge
- AWS Step Functions
- other AWS serverless services
- Build REST APIs and event-driven integration workflows.
- Develop asynchronous messaging and enterprise application integration patterns.
- Build integrations connecting AWS with internal systems and third-party applications.
- Design secure, scalable, resilient integration architectures.




- Build and deploy AWS Lambda functions using production-grade Python.
- Develop reusable API and integration components.
- Create and maintain Infrastructure as Code using:
- Terraform
- AWS CloudFormation
- Automate deployment through CI/CD pipelines, including GitHub-based pipelines.
- Implement secure connectivity using technologies and protocols including:
- REST
- SOAP
- SFTP
- MQ
- Implement API security controls including:
- mTLS
- OAuth / JWT
- rate limiting
- schema validation
- WAF controls
- Troubleshoot production integration issues using logs, traces, CloudWatch metrics, and application monitoring.
- Support migration of integrations from IBM DataPower / IBM ACE to AWS.
- Refactor and modernize legacy middleware integrations into cloud-native AWS architectures.
- Maintain integration platforms through upgrades, monitoring, patching, performance tuning, and reliability improvements.

The client specifically called API Gateway, Lambda/Python, EventBridge, Step Functions, REST APIs, CI/CD and Terraform/CloudFormation core requirements.

Must-Have Skills

- Solid hands-on AWS integration development
- Strong Python development
- AWS Lambda
- API Gateway
- EventBridge
- Step Functions
- REST APIs
- Event-driven architectures
- Serverless architecture
- Enterprise application integration / middleware development
- Terraform or CloudFormation
- CI/CD
- GitHub
- Production troubleshooting
- API security and authentication
- Strong communication skills

You should be able to explain integrations they personally designed and built from scratch. Support-only candidates are unlikely to clear the technical round.

Nice to Have

- IBM DataPower
- IBM App Connect Enterprise / ACE
- IBM Integration Bus
- ESQL / JavaCompute
- IBM API Gateway
- Enterprise middleware migration experience
