Job description

Full Stack Developer – Agentic AI & Automation

About the Role

We are looking for a Full Stack Developer with strong experience in application development, AI integration, and workflow automation. This role focuses on building scalable software solutions while leveraging Agentic AI, AI-powered workflows, and intelligent automation to streamline business operations.

The ideal candidate combines frontend and backend development expertise with hands-on experience building AI agents, orchestrating automated processes, integrating multiple systems, and developing solutions that can independently execute tasks, make decisions, and interact with external tools.

Key Responsibilities

• Design, develop, and maintain scalable full-stack applications.

• Build and integrate AI-powered applications, autonomous agents, and intelligent automation solutions.

• Develop agentic workflows capable of executing multi-step tasks, using tools, retrieving information, and interacting with external systems.

• Design and implement automated workflows to reduce manual processes and improve operational efficiency.

• Integrate LLMs and AI services into applications using APIs and orchestration frameworks.

• Develop AI agents with tool-calling capabilities, memory, contextual reasoning, and task execution.

• Connect third-party platforms, APIs, databases, and business applications to create end-to-end automation solutions.

• Implement Retrieval-Augmented Generation (RAG) and knowledge retrieval capabilities when required.

• Build backend services, APIs, and frontend interfaces to support AI-driven applications.

• Monitor, test, troubleshoot, and optimize AI agents and automated workflows for accuracy, reliability, and performance.

• Identify opportunities to leverage AI and automation to improve existing systems and business processes.

Required Qualifications

• Proven experience in Full Stack Software Development.

• Strong proficiency in JavaScript or TypeScript.

• Experience with frontend frameworks such as React, Next.js, or Angular.

• Backend development experience using Node.js, Python, or similar technologies.

• Experience designing and integrating RESTful APIs and third-party services.

• Knowledge of relational and/or NoSQL databases (PostgreSQL, MySQL, MongoDB, etc.).

• Hands-on experience integrating LLMs such as OpenAI, Anthropic, or Gemini.

• Practical experience developing AI agents and agentic workflows.

• Understanding of tool calling, function calling, agent orchestration, and multi-step task execution.

• Experience building workflow automation solutions and connecting multiple systems.

• Familiarity with prompt engineering, context management, and structured AI outputs.

• Experience with Git, version control, and software development best practices.

Nice to Have

• Experience with Agentic AI frameworks such as LangChain, LangGraph, CrewAI, or AutoGen.

• Experience with automation platforms such as n8n, Make, Zapier, or similar tools.

• Knowledge of Model Context Protocol (MCP) and AI tool integrations.

• Experience implementing RAG architectures and vector databases.

• Experience integrating webhooks, event-driven systems, and asynchronous processing.

• Knowledge of cloud platforms such as AWS, Azure, or Google Cloud.

• Experience with Docker, CI/CD pipelines, and application deployment.

• Familiarity with AI-assisted development tools such as Cursor, GitHub Copilot, or similar platforms.

What We Are Looking For

• Strong problem-solving and systems-thinking abilities.

• Ability to design AI agents that can execute tasks reliably, not just generate text or responses.

• Comfortable working with AI technologies and automation frameworks.

• Ability to build scalable, maintainable, and secure applications.

• Independent, proactive, and focused on delivering practical solutions that improve efficiency.

Contractor Perks

• Work with international clients while maintaining your independent contractor status.

• Minimum 5 paid days off annually, plus US holidays.

• Free access to career growth learning modules through Hyre Academy.

• Scheduled rate increases based on applicable contract terms and performance.
