Preferred Skills: * Cloud & IaC (Preferred): Exposure to cloud environments (AWS preferred), containerization, or Infrastructure as Code (Terraform, CloudFormation, or CDK). * AI Innovation (Preferred): Familiarity with LLM integration, RAG pipelines, or vector databases. ## Description We are seeking an Senior AI-Native Full Stack Developer to join our Digital Customer Experience (DCX) engineering team. In this role, you will lead the development, optimization, and maintenance of our customer-facing web platforms and APIs, serving as an AI-Native Full-Stack Developer. You will act as the primary owner of the transactional payment processing engine, pricing/fee rules, and pipeline automation systems, leveraging cutting-edge AI coding assistants to drive immense engineering velocity, safety, and codebase elegance., * Monorepo & Full-Stack Codebase Stewardship: Maintain, scale, and optimize core frontend and backend monorepos containing React (React 19+) web platforms, TypeScript, and Node.js APIs. Ensure robust error handling, secure authentication flows, and high-performance execution. * Domain Ownership (Payments & Rules Engine): Design, refactor, and safeguard complex payment rules, fee calculation logic, and financial validation flows. Ensure all transactional workflows are highly resilient, compliant, and thoroughly covered by automated test suites. * AI-Augmented Engineering: Embrace and champion AI coding tools (e.g., GitHub Copilot, Cursor, Claude Code) to accelerate development velocity, run complex codebase refactoring safely, and generate robust test coverage. Contribute to internal developer tools, AI agent integrations, or LLM-powered features. * Code Health & Complexity Management: Actively monitor and refactor application files to maintain low cyclomatic complexity. Prevent technical debt buildup by decomposing monolithic codebases (such as routing and state controllers) into testable, modular units. * Mentorship & AI Standards: Mentor junior and mid-level engineers on AI-augmented coding workflows, prompting best practices, and secure AI-generated code validation. * CI/CD, IaC & Automation: Own and optimize delivery pipelines and developer workspaces. Configure automated formatting, continuous integration tests (such as cross-platform line endings), and work alongside DevOps utilizing Infrastructure as Code (Terraform, CDK, or CloudFormation) where applicable. ## Related Videos - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Stop using Node.js like in 2020!
