Full Stack AWS Engineer

Senior Full Stack Developer (AWS, React, Serverless)

Employment Type: Contractor

Department: Technology / Application Delivery

Length of Contract: 3 months. (Contract to Hire).

About the Role

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 on-prem).

Key Responsibilities

Front End (SPA)

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 cross-browser compliance.

Collaborate with Tableau developers to connect workflows between React and Tableau (on-prem). Backend & APIs

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). App Infrastructure & DevOps

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 end-to-end 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. Security & IAM

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. Enterprise Integrations

Build reliable REST integrations with EPM, EDW, and Archer.

Implement resiliency (timeouts, retries, backoff, circuit breakers) and strong monitoring/logging. Quality & Delivery

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). Required Qualifications

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. Nice to Have

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. Soft Skills

Strong ownership and initiative; able to lead designs and code reviews.
