Full Stack Developer

Salary: $95,000 - 120,000 per year Requirements:

• Full-stack ownership across the component layer, API tier, and data layer, without handing off major parts of the work
• Ability to read, modify, and extend production routes, authentication flows, and tests in an unfamiliar codebase with minimal ramp-up
• Strong security judgment, including authentication/session handling, secrets management, least-privilege access, and safe client-side configuration
• Practical, hands-on experience operating AWS production systems directly rather than relying on Terraform alone
• Confidence designing and maintaining CI/CD pipelines, including build automation and rollback procedures
• Working knowledge of DNS, TLS, and CDN caching
• Experience with Cloudflare Access, tunnels, and functions
• Strong debugging skills across logs, load balancers, containers, and browser network activity
• Self-directed work style with the ability to triage independently, ship carefully, and confirm before deploying changes
• Ability to document operations clearly so future maintainers can support the work
• Comfort using AI tools such as Claude, ChatGPT, Copilot, and Cursor, with good judgment about their limitations
• Availability for full-time, on-site work in Alpharetta, GA
• Preferred but not required: payments, gateway, POS, or PCI experience; observability tools; infrastructure-as-code; CRM platforms; automation tools such as n8n, Zapier, or Make

• Own Python and Node APIs, plus a React/Vite single-page application, from end to end, including routes, authentication flows, and testing
• Integrate payment gateways into new POS and third-party platforms by reviewing API documentation, testing in sandboxes, handling tokenization, managing transaction flows, and supporting live deployments
• Operate the AWS production environment directly, including ECS, ALB, S3, CloudFront, Secrets Manager, and IAM
• Manage CI/CD in GitHub Actions, covering container image builds, front-end deployments, and reliable rollbacks
• Run Cloudflare services, including Access, tunnels, and functions, while keeping them clearly separated from AWS responsibilities
• Oversee DNS, TLS, and CDN caching, including clean separation between SPA and API hosts
• Troubleshoot production issues across application logs, load balancers, containers, and browser network behavior
