Senior 1C Developer (Accounting & Payments Integration)

Our client is a well-established and actively operating FinTech company specialising in advanced trading analytics and financial data solutions. As the business scales, the company is investing in modernising its accounting infrastructure - eliminating manual processes and building robust integrations across internal systems, payment providers, and 1C:Enterprise.

This role sits at the core of that transformation. You will design and implement reliable financial data pipelines, ensuring accuracy, compliance, and automation across orders, payments, and reconciliations. It’s an opportunity to take ownership of critical financial systems within a mature, product-driven FinTech environment.

🔍 Responsibilities:

• Design and implement integration between the internal platform and 1C:Enterprise for automated ingestion of orders, payments, and refunds;

• Build scalable data exchange solutions using HTTP services, APIs, or file-based integrations (CSV, XML, etc.);

• Automate scheduled import of bank statements from providers such as Revolut, Wise, PayPal, and others;

• 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;

• Solid understanding of data integrity principles (idempotency, validation, reconciliation);

• 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.

✨ The Employer Offers:

• Fully remote setup with flexible hours and timezone independence;

• Opportunity to work within a stable, established FinTech company with an existing product and client base;

• High ownership and direct impact on core financial infrastructure;

• Competitive, performance-based compensation aligned with European FinTech benchmarks;

• Long-term collaboration potential beyond initial implementation phase;

• Fast decision-making and close collaboration with technical and business stakeholders;
