Python Developer

We are looking for a skilled Python Backend Developer to join the engineering team of a leading pan-European crypto bank. This is a B2B-focused fintech platform that bridges traditional finance and crypto — offering corporate crypto solutions, payment gateways, and innovative investment products for businesses across Europe. You will be contributing to mission-critical backend systems in a fast-moving, compliance-driven environment where engineering quality directly shapes financial infrastructure.

REQUIREMENTS

We're looking for a Python Backend Developer who has:

• 4+ years of professional experience with Python backend development;
• Strong proficiency with Django and Django Channels for real-time and async communication;
• Hands-on experience with Celery for task queue management and background processing;
• Solid experience with PostgreSQL — schema design, query optimization, migrations;
• Practical knowledge of Redis for caching, session management, and message brokering;
• Experience deploying and operating services in Kubernetes (k8s) environments;
• Solid understanding of REST API design, security best practices, and authentication flows;
• Familiarity with compliance and security principles relevant to financial or regulated environments;
• Upper-Intermediate English level or above (B2+).

Nice to Have:

• Experience in fintech, crypto, or banking-related projects;
• Knowledge of blockchain concepts and crypto payment flows;
• Familiarity with MiCA regulatory framework or similar crypto-asset regulations;
• Experience with event-driven architectures and WebSockets.

RESPONSIBILITIES

As a Python Backend Developer, you will:

• Design and develop scalable backend services supporting crypto payment gateways, wallet management, and B2B financial operations;
• Build and maintain RESTful APIs and WebSocket endpoints for real-time data flows;
• Integrate third-party financial services, crypto rails, and external data providers;
• Implement and manage asynchronous task pipelines using Celery and Redis;
• Ensure high reliability and performance of database-heavy systems built on PostgreSQL;
• Collaborate closely with the product and compliance teams to implement features that meet regulatory standards (MiCA, AML/KYC flows);
• Write clean, well-tested, and well-documented code — unit and integration tests are a must;
• Participate in code reviews, sprint planning, and contribute to technical decision-making;
• Maintain and improve CI/CD processes and k8s deployment configurations.

ABOUT THE PROJECT

Our client is the leading pan-European crypto bank — a next-generation financial platform built to empower businesses operating across the crypto and fiat worlds. The platform provides a comprehensive suite of B2B digital banking services:

• Payment Gateway: payment gateway between fiat currencies and cryptocurrencies;
• Wallet Management: wallet management system with integrated reporting and analytics;
• Payroll Solutions: contractor and payroll management tools;
• Corporate Cards: corporate cards for expense management (launching 2026);
• Charitable Contributions: donation and charitable contribution infrastructure.

With Europe accounting for 17.6% of global crypto transaction volume and the MiCA regulation establishing a clear regulatory framework across the EU, this platform is positioned at the center of the next wave of institutional crypto adoption. The team operates with a strong focus on security, compliance, and engineering excellence.
