About us

We’re a Ukrainian startup building a new generation of route-optimization and delivery-automation tools for couriers, drivers, and service businesses.

Our vision — transform chaotic, inefficient deliveries into a seamless, intelligent ecosystem for both individuals and companies.

Now building a scalable, production-grade product from scratch — the foundation for future B2B ecosystem

We’re looking for a Senior Backend Engineer to lead the backend direction and help architect the foundation for a system designed to scale from thousands to millions of users.

Your role

Lead backend architecture for a next-generation mobile app that will scale to millions of users. Work directly with the founder to design the system's architecture, performance, and scalability.

What you'll do

• Architect and implement backend systems using Node.js (NestJS)
• Design scalable data models with PostgreSQL or MongoDB
• Build a modular, high-performance backend ready for multi-service expansion
• Develop containerized infrastructure (Docker + Kubernetes)
• Take part in the configuration and management of AWS environments (ECS/Lambda, S3, RDS, CloudWatch)
• Collaborate with mobile developers for seamless API integration
• Optimize performance, scalability, and fault tolerance

Required skills

• 4+ years of backend development with Node.js / TypeScript
• Expertise with NestJS and microservice or monolithic architecture
• Proficiency in PostgreSQL or MongoDB (schema design, indexing, scaling)
• Experience building distributed, high-load systems
• Strong understanding of AWS (EC2, S3, Lambda, RDS, CloudWatch, IAM)
• Hands-on with Docker, Kubernetes, and CI/CD
• Knowledge of cloud-native design and horizontal scalability
• Strong ownership and independent decision-making

Nice to have

• Event-driven systems (Kafka, RabbitMQ, SQS)
• Real-time data flows (WebSockets, Pub/Sub, Firebase)
• Clean architecture patterns

Soft skills

• Strong technical leadership and architectural thinking
• Clear communication and collaboration
• Proactive problem-solving approach
• Ability to work independently in a startup environment

What we offer

• Core role from day one — shape the entire backend system
• Half autonomy to architect, experiment, and define standards
• Long-term collaboration and meaningful technical growth
• Direct work with the founder, product, and design
• Remote-first, async-friendly, zero bureaucracy
