Chatbot Developer (WhatsApp, Telegram, Discord) - Freelance

Mindrift is looking for skilled Bot Developers (WhatsApp Business API, Telegram Bot API, Discord API) to join the Tendem project (https://tendem.ai/) and build conversational bots and messaging-platform integrations within our hybrid AI + human environment.

What We Do

The Mindrift platform connects specialists with AI projects from major tech innovators. Our mission is to unlock the potential of Generative AI by tapping into real-world expertise from across the globe.

About The Role

This is a freelance role for a Tendem project. As an AI Pilot (the title for this position at Mindrift), you'll collaborate with Tendem Agents that handle repetitive tasks, while you provide bot engineering expertise, conversational design judgment, and quality control to ensure bots are reliable, useful, and ready for real users. You'll design, build, and refine messaging bots for one or more messaging platforms—including WhatsApp, Telegram, Discord, Slack, and similar—for use cases such as customer service, appointment booking, order taking, content delivery, moderation, and automated notifications.

Responsibilities

• Build bots for one or more messaging platforms, such as WhatsApp (Business API / Cloud API), Telegram (Bot API), Discord, Slack, and similar messaging platforms
• Design and implement conversational flows, dialogue state, and fallback handling
• Integrate bots with LLMs (OpenAI, Anthropic, or similar) for natural language responses where appropriate
• Connect bots to backend services, databases, CRMs, and third-party APIs (booking systems, payment, content sources)
• Handle webhooks, rate limits, and platform-specific message formats (interactive messages, buttons, media, templates)
• Evaluate AI-generated bot code and refactor it for correctness, reliability, and graceful error handling
• Implement logging, monitoring, and recovery so bots stay healthy in production

Requirements

• At least 3 years of relevant experience in backend, integration, automation, or bot development (required)
• Bachelor's or Master's Degree in Computer Science, Engineering, Information Technology, or related technical fields is a plus
• Strong foundation in bot development, messaging platform integrations, and building reliable conversational workflows
• Portfolio or examples of bots you've built (required)
• English proficiency: Upper-intermediate (B2) or above (required)

Skills

• At least 1 year of hands-on experience building bots for at least one major messaging platform (WhatsApp, Telegram, Discord, Slack, or similar) is required
• Strong command of Python or Node.js for backend bot logic
• Solid experience with REST APIs, webhooks, OAuth, and async request handling
• Experience with relational or NoSQL databases for storing conversation state and user data
• Familiarity with LLM APIs (OpenAI, Anthropic) and prompt design for conversational use is a strong plus
• Understanding of platform-specific limits, message templates, and approval flows (e.g., WhatsApp template messages)
• Experience with hosting and deployment (Docker, serverless, VPS, or PaaS)
• Strong attention to detail and commitment to bot reliability—no silent failures, no broken flows
• Self-directed work ethic with the ability to design and ship complete bots independently

Schedule

Tasks are estimated to require around 10-20 hours per week during active phases, based on project requirements. This is an estimate, not a guaranteed workload, and applies only while the project is active.

Pay

Contributors can earn up to $60 per hour equivalent, depending on their level and pace of contribution. Compensation varies across projects depending on scope, complexity, and required expertise.

Benefits

• Work fully remote on your own schedule with just a laptop and stable internet connection
• Gain hands-on experience in a unique hybrid environment where human expertise and AI agents collaborate seamlessly—a distinctive skill set in a rapidly growing field
• Participate in performance-based bonus programs that reward high-quality work and consistent delivery
