Since 2013, Duanex has been building bespoke software for international companies and startups — from mobile apps to complex cloud solutions. 

Our clients span health & fintech, digital banking, and large insurance organizations. We follow Agile best practices, and automated testing is a core part of our delivery.

We are looking for a Fullstack Engineer (Node.js + Next.js) to become the main developer on a B2B restaurant operations analytics platform, working under the guidance of the CTO. The product helps restaurant businesses track sales, labor, costs, and operational KPIs.

This is a data-heavy product where customers rely on the platform for business decisions, so data correctness and reliability are critical. The architecture includes a Next.js dashboard, a Node.js data pipeline, Supabase/Postgres, and complex third-party integrations.

What you'll do

• Build and maintain backend services in Node.js
• Work on data ingestion and transformation from third-party APIs (Toast, R365)
• Maintain PostgreSQL schemas, migrations, and access policies
• Build KPI dashboards, reporting features, and admin flows
• Work with async jobs, queues, and scheduled workflows
• Debug data sync issues, permission issues, and production incidents
• Support billing, notifications, and integration-related flows
• Write tests and support CI/CD quality checks

Technical skills

• 3 years of experience 
• Strong commercial experience with TypeScript and Node.js
• Good PostgreSQL and SQL skills
• Production experience with React and Next.js
• Experience with data-heavy systems, reporting logic, or data transformation
• Comfortable working across frontend, backend, and database layers
• Experience writing and maintaining tests
• Experience with AI coding tools, e.g. Claude Code, Codex
• Attention to data correctness and business logic
• English B1+

Would be a plus

• Supabase experience
• ETL / data pipeline experience
• BullMQ / Redis experience
• Experience with POS, restaurant, accounting, fintech, or operational analytics domains

Work format & perks

• Remote-friendly; optional office in Kyiv or Lviv
• The client is US-based, so partial overlap with US hours (e.g. 11:00–20:00 Kyiv time) is a plus
• 20 paid vacation days + 10 paid sick days
• Medical insurance offered after 3 months of employment
• Corporate English classes (group format + speaking club)
