Position Overview

The Senior-Level Developer serves as a technical modernization leader responsible for designing, refactoring, and implementing AWS Cloud Native solutions as part of a large-scale legacy system-of-systems migration initiative.

This role requires expert-level proficiency in Python and deep expertise in AWS services and serverless architecture. The Senior-Level Developer will actively participate in system discovery, contribute to development of a structured systems inventory, and support creation and execution of phased migration plans from legacy on-premises platforms to cloud-native environments.

This position is not limited to feature development; it requires ownership of complex refactoring efforts, architectural fidelity, and integration stability across interconnected modernization workstreams.

Key Responsibilities

Systems Inventory & Migration Planning

• Participate in structured discovery sessions to assess legacy systems, data flows, and integration dependencies.
• Contribute to development of a comprehensive systems inventory documenting:
• Functional capabilities
• Technical stack
• Data dependencies
• Upstream/downstream integration points
• Support development of a phased migration plan, including:
• Refactor vs lift-and-shift analysis
• Risk identification
• Sequencing of interdependent systems
• Hybrid mitigation strategies
• Collaborate with architects and Requirements Engineers to align modernization strategy with technical feasibility.

Expert-Level Python Refactoring & Cloud-Native Redesign

• Lead complex refactor efforts from legacy environments (e.g., SAS, file-based batch systems) to Python-based AWS Cloud Native architectures.
• Redesign algorithms and workflows for scalability and performance.
• Ensure computational and functional equivalence during migration.
• Replace file-based ingestion models with API- and database-driven architectures.
• Optimize high-volume, data-intensive applications for distributed execution.

Expert-level Python proficiency is required, including:

• Advanced data processing
• Modular architecture design
• Performance optimization
• Test-driven development practices

AWS Cloud & Serverless Architecture Implementation

• Design and implement solutions using AWS services such as:
• Lambda
• ECS / EKS
• Fargate
• Aurora/Postgres
• EventBridge
• SNS/SQS
• Glue
• Batch
• S3
• IAM / KMS
• Architect event-driven and serverless patterns.
• Implement scalable containerized workloads.
• Ensure alignment with enterprise cloud guardrails and security requirements.
• Optimize cost, performance, and resilience within AWS environments.

Expert-level experience in AWS Cloud Native architectures and serverless technologies is required.

System-of-Systems Integration Leadership

• Identify cross-workstream integration risks.
• Ensure upstream/downstream compatibility during phased modernization.
• Support design of orchestration patterns to prevent sequencing errors and data thrashing.
• Collaborate with other Senior Developers across workstreams to coordinate shared services and integration layers.
• Participate in architecture review discussions and technical governance forums.

DevSecOps & Automation Integration

• Design CI/CD-aware applications compatible with GitLab or equivalent pipelines.
• Integrate automated testing and security scanning into development lifecycle.
• Troubleshoot pipeline failures and optimize build processes.
• Ensure observability through structured logging, metrics, and monitoring.
• Support infrastructure-as-code alignment (Terraform/CloudFormation collaboration).

Agile Scrum & Technical Leadership

• Participate in Agile Scrum ceremonies.
• Provide technical decomposition of EPICs into implementable features.
• Mentor Mid-Level Developers.
• Assist Product Owner and Requirements Engineer in refining complex stories.
• Contribute to Definition of Done including:
• Code complete
• Automated tests implemented
• Security checks passed
• Documentation updated

Requirements
