Founding Software Engineer & Lead App Developer

Company: TapTip

TapTip is a fintech platform being built to make digital tipping simple, fast, and accessible, particularly across tourism and service industries in developing markets.

Our mission is to bridge the gap between international visitors and local service workers by providing a fast, secure, and accessible way to give and receive digital tips.

Customers should be able to tip using familiar payment methods such as cards, Apple Pay, QR codes, and other digital payment options, while workers have a simple way to receive, track, and withdraw their earnings.

What You'll Build

You will help develop, improve, and maintain the core TapTip ecosystem, including:

• TapTip mobile applications
• TapTip web applications
• User registration and authentication
• Customer tipping and checkout flows
• QR-code-based tipping
• Card payment integrations
• Apple Pay and digital wallet integrations
• Mobile money payout integrations
• User balances
• Transaction history
• Worker payout systems
• KYC and identity verification systems
• Administrative dashboards
• Compliance tools
• Notifications and email systems
• PDF transaction statements and exports
• Secure backend infrastructure
• Payment reconciliation
• Transaction monitoring and tracking
• APIs
• Webhooks
• Third-party financial integrations
• Internal developer and administrative tools

As TapTip grows, you will also help design new products and technical infrastructure for expansion into additional markets.

What We're Looking For

We want someone who can actually build, not someone who only knows how to manage developers or generate code without understanding it.

You should be comfortable working across different parts of a product and figuring things out when there is not already a detailed technical playbook.

We need someone who can take an idea, understand the requirements, determine how it should be built, implement it, test it, fix problems, and help move it into production.

Frontend Experience

Strong candidates should have experience with technologies such as:

• React
• Next.js
• TypeScript
• JavaScript
• HTML
• CSS
• Modern responsive UI development

Backend Experience

Experience with:

• Node.js
• REST APIs
• Firebase
• Firestore
• Cloud Functions or similar serverless infrastructure
• Authentication systems
• Authorization and permissions
• Database architecture
• API integrations
• Webhooks

Mobile Development

We need someone who is talented, dependable, available, and ready to build.

We're looking for a developer who can become a core technical member of TapTip, work closely with us, and help continuously improve the application as the company grows.
