Job summary

MegazoneCloud is seeking Senior Software Engineers to modernize legacy applications, batch workloads, and manual processes into event-driven, agentic architectures on AWS. You will work inside large, multi-vendor client programs.

Responsibilities include decomposing systems, designing target-state blueprints, and operationalizing GenAI workloads with Terraform-based IaC and CI/CD pipelines.

Qualifications

• 5–8+ years of professional software or platform engineering experience.
• Proven delivery of cloud-native solutions on at least one hyperscaler with AWS depth.
• Hands-on experience with core AWS services: Lambda, Step Functions, EventBridge, API Gateway, ECS Fargate, DynamoDB, S3.
• Proficiency in Python and/or TypeScript/Node.js; ability to review code you did not write.
• Terraform or CloudFormation/CDK/Bicep/Pulumi with a willingness to standardize on Terraform.
• Strong grasp of design and integration patterns for resilient, scalable platforms.
• Working familiarity with LLM application patterns and AI/ML workflows.
• Experience in Agile/Scrum or Kanban with JIRA, Git, and modern collaboration tools.
• Bachelor's degree in Computer Science or Software Engineering, or equivalent practical experience.

Responsibilities

• Decompose existing systems, design the target-state architecture, write the services and interfaces.
• Analyze current-state architecture and integration patterns, then produce target-state blueprints.
• Operationalize GenAI workloads on Amazon Bedrock and comparable services.
• Build agents that do real work, generating code and validating outputs.
• Design and review REST or GraphQL API contracts.
• Drive infrastructure-as-code with Terraform and build CI/CD in GitHub Actions, Jenkins, or AWS CodePipeline.
