Job description

Risks Scoring

Risks Scoring is the team responsible for the automated decision-making behind every Plata product. We integrate data from multiple sources, ship scoring models to production, and serve real-time credit decisions under strict SLAs — for credit cards, cash loans, POS lending and debit products across several countries.

Challenges that await you:

• Implementation of scoring features, policy rules and strategies that make real-time decisions on clients in production


• Maintenance and development of an existing high-load Python service and its data contracts


• Ensuring high implementation quality through comprehensive test coverage


• Validating every change against real production traffic before it goes live


• Rapid incident response: tracing a decision through logs and restoring correct behaviour quickly

What makes you a great fit:

• 1+ year of Python experience (internship, own projects or commercial work all count)


• Solid Python fundamentals: OOP, dataclasses, standard library


• Confident with type hints and static type checking


• Basic experience with pydantic: declaring models and validating incoming data


• Docker and an understanding of containerization


• Practical testing experience with pytest: unit and integration tests, parametrized cases, mocking a dependency


• Comfortable with Git and working in a team branch/MR flow


• Basic SQL and ability to read someone else’s code before writing your own


• Proactivity: raising blockers early, asking questions instead of guessing, following existing conventions


• B1 or higher English level for effective communication with an international team

Your bonus skills:

• gRPC / Protobuf


• Kubernetes and Helm


• CI/CD pipelines, GitLab CI in particular


• Kafka, Pub/Sub or any other message broker and event-driven communication


• Interest in MLOps and an understanding of how ML models get to production and are kept there

Our ways of working:

• Innovative Spirit: A commitment to creativity and groundbreaking solutions


• Honest Feedback: valuing open, transparent communication


• Supportive Team: a strong, collaborative community


• Celebrating Achievements: recognizing our wins together


• High-Tech Environment : a team full of smart and revolutionary people who date to challenge the status quo of incumbent finances

Our benefits:

• Relocation support to one of our hubs — Cyprus, Serbia, or Kazakhstan — with assistance for the employee and their family


• Flexible work from one of our offices or remote


• Healthcare Coverage


• Education Budget : Language lessons, professional training and certifications


• Wellness Budget : Mental health and fitness activity reimbursements


• Vacation policy : 20 days of annual leave and paid sick leave
