AI APPLICATION DEVELOPER

Position Summary

Marvin Group is seeking a hands-on AI Application Developer to rapidly prototype, build, and ship useful AI-enabled internal applications. The developer works directly with users, turns practical workflow needs into maintainable software, and improves solutions through feedback and measured results. This is a hands-on, experienced technical individual-contributor role for a builder who can translate real business, engineering, operational, and information-management needs into functioning AI-enabled software.

The Applied AI Developer works directly with business users, operations, engineering, IT, and leadership to identify high-value automation opportunities; rapidly build practical solutions; integrate them with existing systems; and transition successful prototypes into secure, reliable, maintainable production applications. The role combines modern application development, AI/LLM application engineering, API and database integration, intelligent workflow design, cloud-hosted deployment, and practical business-process automation.

This is not an academic AI research role, a pure data-science role, a prompt-writing role, a no-code automation role, or a traditional IT-support role. The role is focused on practical delivery of production applications, AI-enabled tools, agents, integrations, and business automations.

Essential Responsibilities

• Design, develop, test, deploy, maintain, and improve AI-enabled applications, web applications, internal tools, workflow automations, and business systems.
• Work directly with stakeholders to identify operational, engineering, business-process, information-management, and automation opportunities suitable for AI-enabled solutions.
• Translate business requirements and ambiguous operational problems into practical technical architectures, prototypes, deployed applications, and maintainable production systems.
• Build applications using modern technologies such as Python, JavaScript/TypeScript, React, Next.js, Node.js, SQL, REST APIs, databases, web services, and cloud-based application platforms.
• Develop applications using frontier large language model platforms, including OpenAI GPT/Codex, Anthropic Claude/Claude Code, Google Gemini, or comparable technologies.
• Design and implement AI agents, retrieval-augmented generation systems, semantic-search applications, knowledge-retrieval tools, structured-output workflows, tool/function-calling systems, document-processing systems, and multi-step AI automations.
• Integrate AI-enabled applications with enterprise systems, SaaS platforms, databases, APIs, file repositories, operational systems, cloud services, and external data sources.
• Use AI-assisted software-engineering environments and coding agents, including Claude Code, OpenAI Codex, Cursor, GitHub Copilot, or comparable tools, to accelerate design, development, testing, debugging, documentation, and maintenance.
• Rapidly prototype new solutions, validate them with stakeholders, gather feedback, and convert successful concepts into dependable production systems.
• Implement appropriate application security, authentication, authorization, access controls, logging, error handling, monitoring, testing, version control, deployment, and data-protection practices.
• Evaluate emerging AI models, frameworks, agent technologies, development tools, integration platforms, and application patterns for reliability, capability, security, cost, maintainability, and practical business value.
• Document application architecture, system integrations, workflows, data flows, operating procedures, support requirements, technical decisions, and security considerations.
• Help establish practical engineering standards and governance for secure, reliable, and effective internal use of AI-enabled software and automation systems.

Required Qualifications

• Bachelor's degree in Computer Science, Computer Engineering, Artificial Intelligence, Software Engineering, Data Science, or a related discipline
• 2+ years of relevant hands-on experience in software development, application development, systems integration, enterprise applications, technical automation, business systems, information technology, computer engineering, or a comparable technical discipline
• 1+ years of hands-on experience applying modern generative AI, frontier LLMs, AI agents, AI-assisted software development, or AI-enabled workflow automation to real applications, technical projects, or business problems
• Working proficiency in Python and/or TypeScript plus core web concepts such as APIs, HTML/CSS, and client-server behavior
• Experience with SQL or other application databases, data integration, version control, debugging, testing, and deployment workflows
• Ability to evaluate nondeterministic AI behavior, define acceptance checks, recognize failure modes, and communicate tradeoffs clearly
• Hands-on familiarity with modern AI-assisted development tools such as Claude Code and OpenAI Codex, paired with sound engineering judgment and review of generated changes
• Experience integrating applications with APIs, databases, SaaS platforms, enterprise systems, cloud services, operational technology systems, or external data sources
• Ability to understand a business or operational problem, propose an appropriate technical approach, build a working solution, obtain user feedback, and improve the solution based on real-world use
• Strong analytical, systems-thinking, troubleshooting, communication, documentation, and problem-solving capabilities
