It’s an opportunity to take ownership of critical financial systems within a mature, product-driven FinTech environment.

Develop rule-based engines for automatic classification and posting of financial transactions;
Ensure each transaction includes complete accounting metadata (counterparty, ledger account, VAT type, transaction type);
Implement reconciliation mechanisms between internal system data and payment provider transactions, including discrepancy reporting;
Design safeguards to prevent duplicate data entries and ensure data integrity across systems;
Develop custom 1C modules, reports, and scheduled jobs tailored to business processes;
Collaborate with finance and accounting stakeholders to align system logic with reporting and compliance requirements;
Continuously optimise performance, reliability, and maintainability of integrations.
🎓 Requirements:
3+ years of commercial experience with 1C:Enterprise 8.3 (Accounting configuration);
Strong experience integrating 1C with external systems via APIs, HTTP services, or data exchange formats;
Hands-on experience importing and processing bank statements in 1C;

Experience working with structured data formats (CSV, XML, FIDAVISTA or similar);
Understanding of accounting fundamentals (ledger entries, VAT, financial analytics);
Ability to independently estimate, scope, and deliver development tasks.
