Job description

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 supportto 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
