Data Analyst Junior / Junior+ [Core Banking]

We are looking for a Junior / Junior+ Data Analyst to join our Core Banking Systems team.

Our team makes sure that every transaction processed by our banking products is correctly reflected in the accounting system. We work across two markets — Mexico and Colombia — and sit at the intersection of product, technology, data, and finance. This is a great opportunity for someone at the beginning of their career who wants to work with real banking products, production data, and real money from day one.

You’ll start by investigating specific reconciliation cases and gradually move towards owning more complex and systematic problems — with plenty of room to grow along the way. You’ll get exposure to a part of fintech that is usually hidden behind the scenes — the systems that make sure the numbers actually add up.

Challenges that await you:

Reconcile data between the product engine and accounting systems, identify discrepancies, and investigate their root causes

Build and maintain dashboards and reports using DWH data

Improve and standardise reconciliation processes , making them more reliable and scalable

Investigate non-standard product and financial cases together with System Analysts and other teams

Work with production data and gain a deep understanding of how banking transactions move through our systems

Turn complex financial and technical problems into clear, structured solutions

What makes you a great fit:

A mathematical or technical degree from a top university such as MSU, MIPT, HSE, MSTU, MEPhI, or NSE

Strong knowledge of mathematical statistics, probability theory, and systematic thinking

Strong SQL skills

Attention to detail and a willingness to dive deep into complex cases

Ability to work systematically and investigate problems until you understand their root cause

English sufficient for reading technical documentation

Genuine interest in fintech, banking, and financial products

Comfortable working with large datasets and asking the right questions

Would be a plus:

Experience with Airflow & Streamlit

Experience with columnar databases

Experience building or working with AI agents for coding and automation

Our ways of working:

Innovative Spirit: a team from the best technical universities

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 dare to challenge the status quo of incumbent finances

Our benefits:

Relocation support to one of our hubs — Mexico, Serbia or Georgia with full visa & permit support to the employee and family

Flexible work from one of our offices

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
