AI Application Builder / Codex Product Developer

Position: AI Application Builder / Codex Product Developer

Role Type

Full-time or part-time / contract role

Flexible arrangement depending on capability and output.

Role Summary

We are looking for a fast, practical, and product-minded software builder who can help us rapidly develop internal business applications using AI-assisted development tools such as Codex, Claude, ChatGPT, GitHub, and modern low-code/no-code or full-code frameworks.

This role is ideal for someone with some real software or product development experience, ideally around 2–5 years, who is passionate about building useful software products quickly. The person does not need to be the most senior programmer, but they must have enough technical ability, initiative, and product sense to take a business problem, understand the user need, and quickly turn it into a working application or prototype.

We are not looking for someone who needs step-by-step instructions for every task. We need someone who can move fast, think independently, ask good questions, use AI tools effectively, and get applications built, tested, improved, and deployed.

Key Responsibilities

• Build Internal Business Applications:

Develop practical internal applications to help improve business operations across areas such as finance, production, marketing, logistics, quality assurance, reporting, approvals, and workflow management.

• Use AI-Assisted Development Tools:

Use Codex, Claude, ChatGPT, GitHub Copilot, and other AI development tools to accelerate software development, troubleshoot issues, generate code, test ideas, and improve applications quickly.

The candidate should be comfortable using AI as a development partner, not just as a search engine.

• Understand Business Problems and Translate Them into Software:

Work with business users to understand pain points, repeated manual work, operational bottlenecks, and reporting gaps, then convert these into clear application requirements and working solutions.

The person must be able to think like a product builder:

• What is the user trying to achieve?
• What is the simplest useful version of the app?
• What data is needed?
• What workflow should be automated?
• What controls or checks are required?
• How do we make the app easy to use?
• Rapid Prototyping and Iteration:

Quickly create prototypes, test them with users, collect feedback, and improve the application. Speed and practicality are important. We are looking for someone who can deliver useful working versions quickly rather than spend too much time over-engineering.

• Connect Apps to Business Data:

Assist with connecting applications to spreadsheets, databases, APIs, ERP exports, cloud storage, and other internal systems where appropriate.

Experience with tools such as Supabase, Firebase, PostgreSQL, Airtable, Google Sheets, Microsoft 365, OneDrive, SharePoint, SAP exports, Shopify, or similar systems would be helpful.

• Testing, Troubleshooting, and Deployment:

Test applications carefully before release, identify bugs, improve usability, and help deploy applications for internal users. The person should be able to troubleshoot issues independently and work through problems without giving up easily.

Required Skills And Experience

The ideal candidate should have:

• Around 2–5 years of experience in software development, product development, business systems, or application building.
• Some coding experience, preferably with JavaScript, TypeScript, Python, React, Next.js, or similar modern development tools.
• Experience building web applications, dashboards, internal tools, automations, or workflow systems.
• Strong interest in AI-assisted software development using tools such as Codex, ChatGPT, Claude, GitHub Copilot, or similar.
• Ability to understand business requirements and convert them into practical application features.
• Good problem-solving ability and willingness to learn quickly.
• Strong execution mindset: able to get things done without excessive supervision.
• Ability to work quickly, iterate, and improve based on feedback.
• Good communication skills and ability to explain technical matters simply to non-technical users.
• Attention to detail when testing applications and handling business data.

Preferred Skills

The following would be advantageous but are not mandatory:

• Experience with Codex, Cursor, Replit, Lovable, Bolt, Claude Code, GitHub Copilot, or other AI coding tools.
• Experience with Supabase, Firebase, PostgreSQL, or other databases.
• Experience with API integrations.
• Experience with dashboards, reporting tools, or business intelligence systems.
• Experience with ERP, accounting, manufacturing, e-commerce, or operational systems.
• Experience with Microsoft 365, Teams, SharePoint, OneDrive, Google Workspace, Xero, Shopify, or SAP Business One.
• Understanding of product management, UX, workflow design, or process improvement.
• Experience deploying applications using platforms such as Netlify, Vercel, Railway, Render, or similar.

Personal Attributes

We are looking for someone who is:

• Fast, dynamic, and action-oriented.
• Curious and passionate about building software products.
• Comfortable using AI tools to work faster and smarter.
• Independent enough to move projects forward without constant direction.
• Practical and commercially minded.
• Able to understand real business problems, not just write code.
• Willing to test, improve, and fix issues quickly.
• Comfortable with ambiguity and able to create structure from rough ideas.
• Focused on delivering working solutions, not just discussing possibilities.

What Success Looks Like

The successful person will be able to:

• Take a rough business problem and turn it into a working prototype quickly.
• Build useful internal applications that reduce manual work, improve visibility, or prevent errors.
• Use AI tools effectively to speed up development.
• Improve applications based on user feedback.
• Work with business teams to understand their needs.
• Deliver measurable improvements in productivity, accuracy, reporting, or workflow speed.
• Build applications that are practical, usable, and maintainable.

What We Are Not Looking For

We are not looking for:

• A very junior developer who needs constant step-by-step guidance.
• Someone who only follows instructions but cannot think through the product or user need.
• Someone who is slow, overly theoretical, or focused on perfect architecture before delivering value.
• Someone who only knows how to prompt AI but cannot understand or troubleshoot code.
• Someone who builds demos but cannot turn them into usable business tools.

Example Projects

The person may be asked to work on projects such as:

• A daily profitability dashboard using financial and operational data.
• A finance month-end close workflow tracker.
• A quality complaint investigation and response tool.
• A marketing task, KPI, and campaign management system.
• A payment approval tracking system.
• An internal AI knowledge-base connected to company documents.

Application Requirements

Applicants should provide:

• A short summary of their software/product development experience.
• Examples of applications, dashboards, tools, automations, or prototypes they have built.
• Details of any AI-assisted development tools they have used.
• A brief explanation of how they would approach building internal business applications quickly.
• Links to GitHub, portfolio, deployed apps, or relevant project examples where available.
