About the role

PROS is building a dedicated engineering team for a SaaS web app. We're hiring a Full Stack Developer with at least 4 years of AWS experience to join it.

You'll work across the whole stack: a Python backend, a React frontend, and the AWS infrastructure behind them. The roadmap is fixed, with one-week sprints and releases.

Cybersecurity SaaS dev is a plus.

What you'll do

• Build REST APIs and services in Python 3.12+ with FastAPI, Pydantic v2, async SQLAlchemy and PostgreSQL 16

• Build React + TypeScript dashboards, drill-down views and admin screens (TanStack Query, Zod, shadcn/ui)
• Design schemas and migrations using PostgreSQL row-level security and database roles with minimum permissions
• Deploy and run everything on AWS with Terraform: EKS, RDS, ElastiCache, S3, KMS, Secrets Manager, IAM and ALB/WAF
• Keep the GitHub Actions pipeline passing: tests, security scans, SBOMs and signed container images
• Write tests for every story, including pytest, property-based tests and checks that one customer can never see another's data
• Join sprint planning, daily stand-ups and Friday demos with the client

What you bring

• 4+ years of full stack development, including 4+ years running production workloads on AWS
• Strong Python backend skills (FastAPI preferred) and solid PostgreSQL
• Production experience with React and TypeScript
• Hands-on experience with Docker, Kubernetes (EKS preferred) and Terraform
• Secure coding knowledge: OWASP Top 10, OAuth2/OIDC and JWT, secrets management and least-privilege access
• Experience with background job queues (Celery, SQS or similar)
• Comfortable with small pull requests, code review and high test coverage
