And now we need a Senior Python Engineer.

We are looking for an experienced Backend Engineer to join a healthcare-focused technology platform dealing with sensitive medical data and complex system integrations. The role has a strong backend focus, with frontend involvement as a plus.

Project description:

The platform operates in the medical domain, building systems for secure processing, governance, and exchange of health-related data. The products are designed with a strong compliance and governance mindset, reflecting the nature of regulated healthcare environments.

The system consists of several independent products and services, with a mix of legacy and newer components. A major strategic initiative is underway to normalize medical data according to an international standard, enabling better interoperability, reporting, and future integrations, including mobile applications.

What You’ll Be Working On

• Maintaining and evolving legacy Python/Django monoliths that power existing products.
• Developing new backend services using Flask, designed as more modular and service-oriented components.
• Potentially contributing to Node.js-based services for selected new use cases (optional and not yet finalized).
• Supporting a React-based frontend (no Next.js currently) where backend and API design are critical.
• Designing and evolving APIs that integrate multiple systems and databases.
• Contributing to the upcoming medical data normalization initiative, aligning internal data models with international healthcare standards.
• Helping improve development velocity and system stability in a resource-constrained environment.

Technical Environment

Backend

• Python
• Django (legacy monoliths)
• Flask (new backend services)
• Node.js (possible for selected new services)

Cloud & Infrastructure

• GCP, primarily GKE (Kubernetes)
• Some remaining AWS components (legacy services, file storage, external integrations)
• Containerized workloads, CI/CD pipelines

Why This Role Is Impactful

• Direct involvement in core system modernization and backend evolution.
• Opportunity to influence architecture and integration patterns.
• Work on meaningful healthcare problems with real-world impact.
• High ownership and visibility due to current team capacity challenges.
• Exposure to distributed systems, event streaming, and data standardization.

Ideal Profile

• Strong backend experience with Python (Django and/or Flask)
• Comfortable working with legacy systems while building new services
• Experience with Kubernetes and cloud environments
• Familiarity with event-driven architectures
• Frontend exposure (React) is a plus, not a requirement
• Able to work autonomously and prioritize in a fast-moving environment

With us you can:

• Develop your technical knowledge:
• Use latest technologies;
• Participate in technical events and conferences (the cost is covered by the company);
• Opportunity to work with microservices and a lot of modern technology;
• Regular techtalks and professional development.
• Improve your soft skills:
• Build strong teamwork skills and become an essential part of the dynamic teams;
• Improve your English at classes and speaking directly with clients;
• Increase your productivity and communication level via Scrum, Kanban, Agile methodologies.
