Mindrift is looking for skilled Bot Developers (WhatsApp Business API, Telegram Bot API, Discord API) to join the Tendem project and build conversational bots and messaging-platform integrations for real-world applications. In this role, you'll use your bot engineering expertise, conversational design skills, and quality-focused approach to build reliable, useful bots and messaging integrations that deliver a great user experience.
This is a freelance role for a Tendem project. As a Bot Developer, you'll:
- Design, build, and refine messaging bots for one or more messaging platforms, including WhatsApp, Telegram, Discord, Slack, and similar platforms.
- Work on use cases such as customer service, appointment booking, order taking, content delivery, moderation, and automated notifications.
Key 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).
- Review, debug, optimize, and refactor bot implementations to improve correctness, reliability, maintainability, and graceful error handling.
- Implement logging, monitoring, and recovery so bots stay healthy in production.
Qualifications
- At least 3 years of relevant backend, integration, automation, or bot development experience (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.
- Ability to design and maintain production-ready bots, work confidently with APIs, webhooks, and backend services.
- Strong problem-solving skills, attention to detail, and the ability to work independently are essential.
Requirements
- 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.
- Portfolio or examples of bots you've built (required).
- English proficiency: Upper-intermediate (B2) or above (required).
Benefits
- Work fully remote on your own schedule with just a laptop and stable internet connection.
- Apply your expertise to real-world technology projects while gaining experience building high-quality solutions for a global platform.
- Participate in performance-based bonus programs that reward high-quality work and consistent delivery.
