Overview

Our client is entering the execution phase of a major loyalty and partner-platform integration initiative involving large-scale transactional systems, enterprise APIs, settlement workflows, and modernization of existing applications into cloud-native AWS services.

We are seeking a highly hands-on Senior AWS Developer / Tech Lead who can actively lead engineering delivery while remaining deeply involved in architecture, coding, integration design, and implementation. This individual will establish development patterns, mentor engineers, drive technical quality, and collaborate directly with client stakeholders in a fast-moving Agile consulting environment.

This is not a pure coordination or architecture role. The successful candidate must be a strong senior engineer capable of designing and building production-grade AWS serverless and event-driven systems while guiding the broader development team.

• Design, develop, and implement AWS-based cloud-native and serverless applications
• Build scalable event-driven and API-centric integration solutions supporting transactional and settlement workflows
• Modernize legacy or existing enterprise applications using modern AWS services and serverless architectures
• Develop and support enterprise integrations between client systems, loyalty platforms, downstream systems, and external partners
• Design and implement RESTful APIs and asynchronous integration patterns
• Implement Infrastructure-as-Code solutions and deployment automation using Terraform
• Collaborate with architects, QA, DevOps, product owners, and client technical stakeholders throughout the delivery lifecycle
• Participate in Agile ceremonies including sprint planning, backlog refinement, technical design discussions, and estimation activities
• Support platform engineering efforts related to deployment, observability, monitoring, resiliency, and operational readiness
• Contribute to technical documentation, architecture artifacts, and implementation guidance
• Drive engineering quality through code reviews, pairing, technical leadership, and continuous improvement practices

Required Qualifications

• 8+ years of software engineering experience with significant experience delivering AWS-based enterprise solutions
• Proven experience acting as a Technical Lead or Senior Lead Developer on cloud modernization or integration-heavy initiatives
• Strong hands-on experience with AWS serverless and event-driven architectures including:
• AWS Lambda

• Amazon EventBridge
• SQS / SNS
• API Gateway

Strong development experience with:

• Java
• Spring Boot
• TypeScript
• Experience building scalable microservices and distributed systems
• Strong understanding of API integration patterns, asynchronous messaging, orchestration workflows, and transactional processing
• Hands-on experience implementing Infrastructure as Code using Terraform
• Experience with GitHub-based development workflows and CI/CD pipelines
• Experience working within Agile delivery teams using Jira and Confluence
• Strong communication and stakeholder collaboration skills
• Comfortable working directly with client technical teams in a consulting delivery environment
• Strong debugging, troubleshooting, and production support mindset

Preferred Qualifications

• Experience with loyalty, settlement, retail, payments, fuel/convenience, or transactional enterprise systems
• Experience modernizing monolithic applications into cloud-native architectures
• Familiarity with containerized workloads and Kubernetes/EKS environments
• Experience with observability and monitoring tooling in AWS environments
