Genesis10 is seeking a Senior Full Stack Developer (AWS, React, Serverless) for a hybrid 6-month contract to hire position with a leading client in Columbus, OH.
Compensation: $80.00 - $95.00 per hour, W2. Description: We are seeking a Senior Full Stack Developer to lead the implementation of a secure, highly available, and enterprise-integrated single-page application running on AWS. You will build a React-based front end (with AG Grid), serverless APIs (API Gateway Lambda/Python), and containerized infrastructure (Fargate Nginx ALB), with integrations to EPM, EDW, and Archer via REST APIs.
You will also lead AWS resource deployment, Terraform-based IaC, Azure DevOps/ADO pipeline creation, and other DevOps tooling and automation initiatives, including full application stack deployment and development.
Collaboration with architecture, security, data, and reporting teams will be essential to meet standards around identity (Azure AD SSO), monitoring (CloudWatch/Splunk), and reporting (Tableau onprem).
Job Duties: - Build responsive, accessible SPAs using React, HTML5, and CSS.
- Implement AG Grid for enterprise-grade grid features (virtualization, server-side pagination, row grouping, custom cell renderers).
- Optimize client performance (code splitting, memoization, lazy loading) and ensure crossbrowser compliance.
- Collaborate with Tableau developers to connect workflows between React and Tableau (onprem).
- Design and implement RESTful services using AWS API Gateway and AWS Lambda (Python).
- Build event-driven services using EventBridge Lambda with idempotency and retry patterns.
- Model/query data in Aurora (PostgreSQL/MySQL) with performant schemas and migrations.
- Enforce API standards (versioning, pagination, error handling, Swagger/OpenAPI documentation).
- Deploy and configure AWS Fargate tasks, Nginx, and ALB for hosting and routing.
- Implement AWS resource deployment across environments.
- Build CI/CD pipelines using Azure DevOps (ADO) and other DevOps tooling for endtoend build/test/deploy automation.
- Implement IaC using Terraform and/or CloudFormation.
- Maintain full application stack deployment (frontend, backend, infrastructure).
- Apply CloudWatch metrics/logs/alarms and Splunk dashboards for observability.
- Integrate Azure AD SSO (OAuth/OIDC) for secure authentication/authorization.
- Apply security best practices: least-privilege IAM, secrets management (Secrets Manager/SSM), input validation, and secure Nginx headers.
- Build reliable REST integrations with EPM, EDW, and Archer.
- Implement resiliency (timeouts, retries, backoff, circuit breakers) and strong monitoring/logging.
- Write unit/integration tests for frontend and backend, with automated test gates.
- Participate in Agile ceremonies and deliver incremental value.
- Produce clear documentation (architecture, runbooks, API specs).
Requirements: - 5-8 years of professional software development experience.
- Strong React expertise (hooks, composition, performance tuning).
- Hands-on AG Grid experience in enterprise use cases.
- Python proficiency for Lambda and automation.
- Production experience with core AWS services (API Gateway, Lambda, Fargate, ALB, EventBridge, Aurora, CloudWatch).
- Experience with AWS resource deployment, Terraform, Azure DevOps (ADO), and DevOps tooling for CI/CD.
- Strong experience with full application stack development and deployment.
- OAuth/OIDC integration with Azure AD SSO.
- Solid understanding of security, VPC networking, and container fundamentals
- Strong ownership and initiative; able to lead designs and code reviews.
- Clear communication across technical and nontechnical audiences.
- Empathy and collaboration with partner teams.
- Mentorship mindset with commitment to elevating engineering quality.
Preferred Qualifications: - Nginx hosting optimizations (caching, compression, security headers).
- Tableau integration experience.
- Splunk queries, alerting, dashboards.
- OpenAPI/Swagger, JSON Schema, contract testing.
- Performance optimization for AG Grid and React.
- Experience with governance, audit, and regulated data practices.
