Business Analyst (FinTech / Accounting, ERP)

Hi! Tallium is looking for a Mid+/Senior Business Analyst with strong accounting domain expertise to join a new enterprise project.

About the project
A new enterprise accounting & ERP platform built from scratch on an "accountant-first" principle: a rule-driven posting engine generates the General Ledger from operational registers, so every number in a report can be traced back to its source document. The first phase covers core accounting, AR/AP, inventory, payroll, banking and financial reporting.

What you'll do

• Act as the accounting domain expert, working directly with the client's CFO and finance team
• Turn accounting concepts (posting rules, control accounts, close process) into clear, testable requirements
• Model processes (O2C, P2P, reconciliation, period-end close) and financial data structures
• Specify posting rules, account mapping, validations, approval flows and access / SoD rules
• Manage MVP scope and priorities together with the PM
• Prepare acceptance criteria and test scenarios with QA using sample transactions
• Run client workshops and discovery

Who we're looking for

• 4+ years as a BA, System Analyst or PO
• 2+ years on accounting, ERP, core banking or other financial systems projects (a background as a functional consultant, accountant, controller or financial analyst is a big plus)
• Strong knowledge of double-entry accounting: CoA, GL, journals, sub-ledgers, trial balance
• Hands-on understanding of O2C, P2P, period-end close, bank reconciliation and financial statements
• Familiarity with multi-currency, VAT / withholding tax and financial controls (audit trail, maker-checker, SoD)
• Solid BA toolkit: workshops, BPMN / UML / ERD, Jira / Confluence, user stories and specifications
• Understanding of integrations and APIs, Agile experience on mid-size or large projects
• Advanced English

Nice to have

• Experience with ERP / accounting systems: SAP, NetSuite, Dynamics 365, Odoo, Xero, 1C / BAS, etc.
• Experience with posting engines, sub-ledgers or event-based accounting
• E-invoicing / tax fiscalization experience
• IFRS / GAAP knowledge or a finance / accounting degree
• Bank integrations (MT940, CAMT.053, ISO 20022), basic SQL

What we offer

• Interesting, influential projects and long-term cooperation
• Flexible schedule, remote or hybrid work
• Individual growth plan, development budget, workshops and training
• Stable salary and planned reviews
• 21 vacation days, 10 sick days, all public holidays off
• Medical insurance
• Corporate English and team building
