Job summary

WhiteWater Express Car Wash in Houston is seeking a Full Stack Engineer to lead development of internal web apps, reporting tools, and middleware services. You will own the internal portal, middleware, and reporting platform, collaborating with the Data Engineering team to turn CRM data into actionable applications.

You’ll work with a Node.js/Next.js stack, leverage AI tools to accelerate delivery, and ensure security and production-readiness.

Qualifications

• 5+ years of full-stack software development experience.
• Advanced Node.js skills, including building and maintaining production web applications and APIs.
• Strong skills in HTML, CSS, and JavaScript for web application and data-input interfaces.
• Strong SQL and data modeling knowledge (PostgreSQL; facts, dimensions, star schema).
• Working knowledge of AWS application services and a willingness to grow into our environment (you won’t need to own every service).
• Experience using AI tools in a development workflow, including the ability to validate, test, and refine AI-generated code rather than accepting output at face value.
• Experience with Git/GitHub version control.
• Strong analytical, problem-solving, and communication skills.
• Bachelor’s degree in Computer Science or related field, or equivalent practical experience.
• Proof of U.S. citizenship is required; this position is not eligible for visa sponsorship.

Responsibilities

• Design, build, and maintain a scalable internal portal (Next.js) and new reporting features using Node.js and Fastify.
• Build type-safe APIs and middleware using Fastify with Zod for schema validation.
• Develop responsive, data-rich front-end interfaces using React and Next.js.
• Use AI tools (e.g., Claude.ai, MCP) to accelerate development of web applications, middleware, and back-end features.
• Critically review, test, and validate all AI-generated code and output to ensure it is secure, performant, and production-ready—treating AI as an accelerator, not a substitute for engineering judgment.
• Apply strong UI/UX practices to create intuitive, clear, and actionable interfaces.
• Develop and maintain middleware and APIs, integrating internal systems and CRM data sources.
• Build and operate cloud-based application services on AWS, including containerized deployments on Fargate, partnering with the Data Engineer on infrastructure as needed.
• Handle CRM and operational data responsibly, following least-privilege and secure-by-default practices (e.g., Secrets Manager for credentials, scoped access to data).
• Collaborate closely with the Data Engineer to define and own the front-end data stack.
• Collaborate with business leaders and the Data Engineering team to gather requirements and deliver solutions.
• Document applications and provide training and support to business users.
• Use Python as needed for scripting, data processing, or integration tasks alongside the Data Engineering team.
• Maintain and extend existing PHP-based systems and integrations as needed.
