In this role, as an AI Pilot – that's how we refer to 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.

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).

Mindrift
About MindriftMindrift connects specialists with project-based AI opportunities for leading tech companies, focused on testing, evaluating, and improving AI systems. Participation is project-based, not permanent employment.What This Opportunity InvolvesWe're building a dataset to evaluate AI coding agents - how well a model handles real-world developer tasks. You'll create challenging tasks and evaluation criteria within realistic simulated environments.Key ResponsibilitiesBuild realistic developer environments - a virtual company with codebase, infrastructure, and context (tickets, docs, conversations) that forms a believable development historyDesign tasks from intermediate states of these environments - craft the prompt, define what "solved" means, and ensure the task is solvable by an AI agentWrite tests that verify agent solutions - accept all valid approaches and reject incorrect ones, neither too strict nor too lenientIterate on tasks and tests based on QA feedback - review agent solutions, analyze failures, and refine until the evaluation is fair and robustWhat This Is NOTNot data labelingNot prompt engineeringNot writing code from scratch - the agent writes most of the code; you guide and evaluateWhat We Look For8+ years in software developmentCore stack: Python (FastAPI), JavaScript/TypeScript (React), Docker, Postgres, Kafka, RedisExperience writing tests (functional, integration)English proficiency - B2+Why This Is HardFrontier models are already good at coding. Creating a task that genuinely challenges the best models is non-trivial. You need to deeply understand where models fail and what scenarios reveal the difference between a good and a bad solution. Tasks have many valid solutions - writing tests that accept all correct solutions and reject incorrect ones is harder than it sounds.How It WorksApply → Pass qualification(s) → Join a project → Complete tasks → Get paidEffort EstimateTasks for this project are estimated to take 30 hours to complete, depending on complexity.
