About the role
Senior-Level Developer 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 practicesAWS Cloud & Serverless Architecture Implementation
- Design and implement solutions using AWS services such as:
- LambdaECS / EKSFargateAurora/Postgres
- EventBridgeSNS/SQSGlueBatchS3IAM / KMSArchitect 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
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
