Full Stack Developer – AI-Enabled Engineering (Mid level)

Roseland NJ - Hybrid (3 days onsite) - Locals only

Focus: Full Stack Development / AI-Assisted Software Engineering

Position Overview

We are seeking a highly motivated Full Stack Developer to join a fast-moving engineering team building modern applications in an AI-first development environment.

This role requires strong traditional software engineering fundamentals combined with the ability to work effectively with AI-assisted and agentic development workflows. AI will generate and accelerate a meaningful portion of the development process, but the engineer must have the technical depth to evaluate that output, identify problems, troubleshoot issues, and ensure the resulting software meets production-level engineering, architecture, and quality standards.

The ideal candidate is a strong full-stack engineer who is curious, independent, comfortable working across the technology stack, and able to quickly understand the business domain behind the applications they are building.

Key Responsibilities

• Design, develop, test, and deliver full-stack application features across front-end and back-end technologies.
• Build modern web applications using React, JavaScript/Node.js, AWS, Lambda, and GraphQL.
• Work within an AI-enabled/agentic software development lifecycle, using AI throughout requirements analysis, specification development, implementation, and troubleshooting.
• Review and validate AI-generated code for correctness, maintainability, scalability, security, and adherence to engineering standards.
• Identify architectural, design-pattern, and code-quality issues that may not be apparent from simply executing generated code.
• Translate product and business requirements into clear technical specifications and implementation plans.
• Develop a strong understanding of the business domain to identify requirements, dependencies, edge cases, and potential issues early in the development lifecycle.
• Work collaboratively in small engineering teams or pairs to deliver complete features from requirements through production.
• Troubleshoot complex application issues across the full technology stack.
• Communicate effectively with engineering teams, product partners, internal stakeholders, and clients.
• Contribute to the continued development of engineering standards and AI-assisted development practices.

Required Qualifications

• Strong full-stack software development experience with solid knowledge of both front-end and back-end engineering.
• Strong experience with React and JavaScript.
• Experience developing backend applications using Node.js.
• Experience working with AWS, including serverless technologies such as AWS Lambda.
• Experience with APIs and technologies such as GraphQL.
• Strong understanding of software architecture, design patterns, coding standards, and software development best practices.
• Demonstrated ability to review, troubleshoot, and improve code rather than simply produce working code.
• Ability to independently analyze requirements and identify technical considerations, dependencies, and potential gaps.
• Strong analytical and problem-solving skills.
• Excellent written and verbal communication skills.
• Ability to operate effectively in a fast-paced and evolving engineering environment.

Preferred Qualifications

• Experience using AI-assisted development tools or agentic AI development workflows.
• Experience with tools such as Claude Code or comparable AI coding environments.
• Experience using AI to synthesize requirements, generate specifications, implement features, troubleshoot issues, or accelerate development.
• Familiarity with Human Capital Management (HCM), payroll, HR technology, or workforce management domains.
• Previous experience with ADP or organizations operating in similar HCM/payroll environments is beneficial.
• Experience working on teams where engineers own complete features across the technology stack.
