Senior AWS Integration Developer

Work Model: Hybrid, currently ~3 days/week in office

Experience: 7+ years preferred; exceptional candidates with 5–6 years of highly relevant experience may be considered
Employment Type: Full-time
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
