Warsaw Minsk Tbilisi, Беларусь IDT Полный рабочий день 60 000 руб. - 120 000 руб. в год
We are looking for a skilled Software Engineer to join our team and help build a greenfield  WhatsApp conversational bot embedded into our money remittance platform.
This is not just another chatbot project — it combines AI-driven prompt engineering, human-centered conversational UX, and complex backend integrations for a product that will handle regulated, real-money transactions.
You'll be joining after the prototype stage, helping shape the long-term system architecture as we move from prototype to full-scale production, and directly influencing both the technical architecture and the user experience. Position Opportunity:
  • Want to work at the intersection of AI, human behavior, and software? Here, prompt engineering is not an afterthought — it's the heart of the product. You'll design prompts and flows that keep the conversation useful, natural, and on track, even when users try to take it sideways.
  • Interested in designing how humans talk to machines? You'll be crafting natural language UX: guiding users who don't know the "script" through complex financial flows while keeping the interaction friendly, efficient, and complaint.
  • Like building rock-solid backend systems? From integrating with the WhatsApp Cloud API to payment processing systems, you'll engineer services that connect AI conversations to real-world transactions.
What You'll Do:
  • Design, implement, and refine prompt engineering strategies for LLM-based conversational flows using LangChain, LangGraph, and custom NLP logic.
  • Collaborate with Product Owners, QA, and other developers to shape conversational UX — anticipating user needs, guiding them through scenarios, and handling unpredictable inputs gracefully.
  • Develop and maintain backend systems in Python, NestJS, and for integrations with Meta's WhatsApp Cloud API, payment platforms, and internal services.
  • Implement secure, compliant flows for transactions and personal data handling.
  • Deploy and operate services in Docker/AWS using AWS CDK and modern DevOps practices.
  • Contribute to the full development lifecycle: architecture, coding, testing, deployment, and monitoring.
We Expect You to Have:
  • Deep knowledge and 5+ years of production experience
  • Solid backend development skills with (Python is a plus).
  • Experience integrating with complex third-party APIs (payments, messaging, etc.).Proficiency in frontend development using JavaScript/TypeScript and React.
  • Familiarity with Сloud and container technologies
  • English proficiency – B2 or higher.
It Would Be a Plus To Have:
  • Experience with Meta's WhatsApp Business Platform or other messaging APIs (Telegram, Viber, etc.).
  • Experience with LangChain and LangGraph.
  • Experience in business analysis and communications with users and stakeholders. Work on financial/payment-processing systems.
  • Experience in building scalable and highly-available system architectures.
  • Hands-on experience with Amazon Web Services (AWS).
We are pleased to offer you:
  • Remote work opportunity
  • B2B Employment ($, gross).
  • Really good hardware.
  • An exciting and challenging job with talented people around.
  • Great learning and growth opportunities.
  • Compensation for professional training, seminars, and conferences.
  • First-class English lessons.
