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
