• Experience scaling to 100K+ users and handling high transaction volume.
• Background in AML/KYC compliance or financial data handling.

Tech Stack
Core: Node.js, Express, TypeScript, PostgreSQL, Prisma ORM, GraphQL, RabbitMQ, gRPC
Supporting: REST APIs, Webhooks, Real-time data sync, Multi-tenant architecture, Audit logging

What We Offer

• Full backend ownership and architectural control.

• Competitive compensation and benefits package.

We run a B2B data platform for the entertainment industry — it tracks talent, who represents them, the deals they're doing, and the data surrounding all of it. The product is established and has been around for almost 10 years with paying customers; we're not a pre-launch startup.
 

We're rebuilding the platform from Symfony/Angular to Django and React, and we're hiring a senior developer to lead the rebuild — owning the architecture, setting technical direction, and assigning and reviewing work for our current developer. After the rebuild ships, you'll stay on as the long-term owner of the system. 

This is a permanent role, not a contract that ends with the migration.

We want more than a ticket-taker. You should understand the business logic behind what you're building, push back when a requirement doesn't match how users actually work, and drive architecture decisions.

Must have

• 6+ years of professional Python/Django experience
• Strong experience building REST APIs with Django REST Framework
• Has built and shipped systems from scratch, and owned a codebase long-term
• Experience with data-heavy applications (large datasets, complex querying, migrations)
• Comfortable leading: planning work, delegating tasks, and reviewing another developer's code
• Strong written and spoken English — you'll work directly with non-technical stakeholders
• 4+ hours of daily overlap with US Eastern time
• Advanced English speaking

Nice to have

• Hands-on React experience (our frontend stack)
• Experience rebuilding or migrating legacy systems (Symfony familiarity a bonus)
• Django Admin customization
• Third-party API integrations

We’re looking for a Senior Backend (Python) Engineer to join our team. 

Work Location: Poland (Krakow), Slovakia (Kosice) or Czechia (Prague). 

Hybrid: 2+ days per week in the office, the rest remote.

The Mission

We are building a complex, real-time ecosystem for micromobility and logistics systems sim—where split-second logistics meet seamless user experiences. We need a Senior Backend (Python) Engineer powerhouse to lead the development of our Customer Mobile Web App and our high-utility Internal Admin Panels.

You’ll be the bridge between the sleek, high-performance interface our users see and the robust, scalable Python services that power the logic.

Key Responsibilities

• Mobile-First Frontend: Architect and scale our React-based mobile web application, ensuring 60fps performance and offline-first capabilities.
• Operational Control Centers: Build dense, data-heavy Admin Panels that allow our operations team to monitor real-time logistics, manage users, and handle complex dispatching.
