We are currently looking for a Treasury Analyst to join our Treasury Team (office-based in Warsaw, Poland).

About the role

Treasury Analyst will be responsible for managing day-to-day treasury operations across multiple entities — ensuring accurate cash flow planning, timely execution of payments, and maintaining reliable banking infrastructure.

The successful candidate will take end-to-end ownership of key operational treasury processes and actively contribute to process improvements with a focus on automation and AI-driven solutions. Over time, the role will expand towards independent management of liquidity, FX, and treasury infrastructure development.

We operate in a fast-paced, multi-entity international environment where treasury matters vary in complexity — from routine payment execution to strategic liquidity decisions.

• Execute and coordinate intragroup payments, including international transfers (SEPA, SWIFT, ACH)
• Monitor cash balances across entities and manage FX exposure
• Communicate with international banks on operational matters, requests, and clarifications
• Monitor and control banking fees, identify optimization opportunities
• Prepare dashboards and management reports

At later stages

• Take full ownership of key treasury functions: cash flow forecasting, liquidity management, and bank communication
• Support excess liquidity management, including deposit placements and securities purchases
• Initiate and lead treasury automation projects with a focus on AI solutions
• Contribute to banking infrastructure development and account setup processes

What to expect in this role

• Managing multiple parallel tasks in a dynamic, high-growth environment
• Frequent ad-hoc requests and time-sensitive operations
• High level of ownership and autonomy from day one
• Exposure to international banking and multi-entity structures
• Evolving processes — you'll shape them, not just follow them

Required qualifications and skills

Must-have

• 3–4 years of experience in Treasury or Finance at international companies, banks, or IT firms
• Strong analytical skills and attention to detail
• Proficient in Excel and Google Sheets
• Experience processing international payments: SEPA, SWIFT, ACH
• English B2+

Nice-to-have

• Experience in financial modelling: budgeting, CF forecasting
• ACCA in progress
