Senior Python Engineer

Ucrânia

The CHI Software team is not standing still. We love our job and give it one hundred percent of us! Every new project is a challenge that we face successfully. The only thing that can stop us is… Wait, it’s nothing! The number of projects is growing, and with them, our team too.
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.

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
