Lead Full-stack Software Engineer (Node.js + React) for WhatsApp Bot Project

We’re looking for an experienced engineer to help build a greenfield WhatsApp conversational bot embedded into our money remittance platform. This role is focused on backend and frontend development with Node.js and React, integrating the bot into a regulated, real-money transaction environment.

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:

• Develop and maintain backend services in Node.js/NestJS for integrations with WhatsApp Cloud API, payment platforms, and internal systems.
• Build frontend components and tools in React / TypeScript to support the conversational experience.
• Implement secure, compliant flows for financial transactions and personal data handling.
• Contribute to the system architecture and help scale from prototype to production.
• Deploy and operate services in Docker/AWS using CDK and modern DevOps practices.
• Collaborate with Product, QA, and AI engineers to ensure smooth UX across integrations.

We Expect You to Have:

• 5+ years of professional software engineering experience.

• Strong backend skills with Node.js / NestJS.

• Proficiency in React and modern JavaScript/TypeScript.

• Experience integrating with complex third-party APIs (payments, messaging, etc.).

• Familiarity with cloud and containerization (AWS, Docker, Kubernetes).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.).
• Background in financial or payment-processing systems.
• Knowledge of scalable and highly available architectures.
• Hands-on AWS experience.

• Modern office with free parking in the very center of Minsk.

• Remote/ hybrid work opportunity!

• An exciting and challenging job with talented people around.

• Competitive salary and growth opportunities.

• Really good hardware.

• 26 vacation days & 5 fully covered sick days without sick leave required per year.

• Compensation for professional training, seminars, and conferences.

• Sports activities reimbursement.

• Medical insurance and sports reimbursement.

• Referral program – get rewarded for helping us grow the team with talented people.

• Company-supported English classes to enhance your professional growth.
