What Is the role?

We are looking for a Full Stack Developer who can build and ship web applications end-to-end — Next.js on the frontend, NestJS or .NET on the backend, PostgreSQL and MongoDB for data, all running on AWS.

  • Implement RESTful APIs with proper validation, error handling, and documentation
  • Write data access layers against PostgreSQL and MongoDB
  • Build background jobs and event-driven workflows with AWS Lambda and SQS
  • Implement auth using JWT, OAuth 2.0, and AWS Cognito
  • Develop middleware for logging, rate limiting, and request handling

Data:

  • Design and manage relational schemas in PostgreSQL (migrations, indexing, query optimization)
  • Model and query document data in MongoDB (aggregation pipelines, indexing strategies)
  • Make pragmatic decisions about when to use relational vs. document storage

Infrastructure & DevOps:

  • Containerize applications with Docker and deploy to AWS ECS/Fargate
  • Set up CI/CD pipelines with GitHub Actions or AWS CodePipeline
  • Monitor applications with CloudWatch and set up meaningful alerts
  • Manage infrastructure using AWS CDK or CloudFormation

General:

  • Write clean, maintainable code following established patterns
  • Participate in code reviews and help maintain team standards
  • Optimize performance and troubleshoot production issues

Required Skills

Frontend:

  • 2+ years with React and Next.js (App Router)
  • Solid TypeScript skills — you use it daily, not optionally
  • Experience with React 19 patterns: Server Components, Suspense, and the use hook
  • State management with Zustand or TanStack Query (server state vs. client state)
  • Styling with Tailwind CSS v4
  • Understanding of Core Web Vitals and practical performance optimization

Backend:

  • 2+ years with either:
    • NestJS and Node.js (decorators, modules, providers, guards), OR
    • .NET (ASP.NET Core) and C# (Minimal APIs or Controllers)
  • Solid understanding of RESTful API design and implementation
  • Auth implementation: JWT, OAuth 2.0, session management
  • Experience with ORMs — TypeORM/Prisma/Drizzle (Node) or Entity Framework Core (.NET)
  • Comfortable with async patterns and error handling in production

Databases:

  • PostgreSQL — schema design, indexing, migrations, and writing efficient queries
  • MongoDB — document modeling, aggregation framework, and indexing
  • Understanding of when to choose relational vs. document databases for a given problem
  • Experience with database migration tools (TypeORM migrations, Prisma Migrate, EF Core migrations)

AWS (Core):

  • ECS / Fargate — container deployment and scaling
  • Lambda — serverless functions for event-driven workloads
  • SQS — message queuing between services
  • Aurora PostgreSQL or RDS — managed relational databases
  • CloudWatch — logging, metrics, and alerting
  • S3 — object storage for files and assets
  • Cognito or IAM — identity and access management

General:

  • Docker — writing Dockerfiles, multi-stage builds, local dev with compose
  • Git — branching strategies, PRs, rebasing
  • Unit and integration testing (Jest/Vitest, xUnit)
  • Redis for caching and session management
  • CI/CD pipeline setup and maintenance

Preferred Skills

AWS (Advanced):

  • AWS CDK or CloudFormation for Infrastructure as Code
  • EventBridge for event-driven architectures
  • API Gateway for managed API endpoints
  • ElastiCache (Redis) for distributed caching
  • CloudFront for CDN and edge caching
  • Step Functions for workflow orchestration

Additional:

  • Microservices architecture in production
  • Message brokers beyond SQS (RabbitMQ, Kafka)
  • Elasticsearch or OpenSearch for search functionality
  • GraphQL or tRPC
  • Monorepo tooling (Turborepo, Nx)
  • Web security best practices (OWASP Top 10)

  • You solve problems methodically and don’t shy away from debugging
  • Clear communicator — can explain technical decisions to non-technical stakeholders
