Description
Mindrift (Toloka) is looking for skilled Bot Developers (WhatsApp Business API, Telegram Bot API, Discord API) to build conversational bots and messaging-platform integrations within our hybrid AI + human environment. In this role, as an AI Pilot – that's how we refer to this position at Mindrift – you'll collaborate with 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. This part-time remote opportunity is ideal for professionals with hands-on experience building messaging bots, working with platform APIs and webhooks, and implementing conversational logic.
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
As a Bot Developer, you'll design, build, and refine messaging bots across WhatsApp, Telegram, Discord, and similar platforms — for use cases such as customer service, appointment booking, order taking, content delivery, moderation, and automated notifications.
Key Responsibilities
- Build bots for WhatsApp (Business API / Cloud API), Telegram (Bot API), Discord, 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 and benefits
Educational qualifications
- At least 3 years of relevant experience 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.
Academic and/or Professional Experience
Candidates should have a strong foundation in bot development, messaging platform integrations, and building reliable conversational workflows. We are looking for specialists who can design and maintain production-ready bots, work confidently with APIs, webhooks, and backend services, and refine AI-assisted output into stable, user-friendly experiences. Strong problem-solving skills, attention to detail, and the ability to work independently are essential.
Technical Skills (Essential)
- At least 1 year of hands-on experience building bots for major messaging platforms (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)
Additional requirements
- 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).
Project time expectations
For this project, 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.
The process is designed to move quickly and typically includes the following steps:
- App review and invitation to a virtual project introduction session (approximately 30 minutes)
- Platform registration and identity verification
- Technical assessment (approximately 35 minutes)
- Background check (completed at no cost to candidates)
- Onboarding and project-specific training tasks
- Begin production work!
- Willingness to complete identity verification as part of the onboarding process.
- Ability to complete a technical assessment.
