Careers

Master Data Engineer

You are responsible for order in clients' master data — products, counterparties, locations, people, contracts — in our database and with our tools: Ordo, Merx, Messor and the kit set.

What you will do

• Build and maintain the master data model in PostgreSQL: one reference list across several accounting systems, value history, a source for every record.
• Merge duplicates and match records from different sources with rules and models: probabilistic matching, classification, extracting attributes from text.
• Set data quality rules and run the stewards' queue in Ordo: what the machine decides itself, what it hands to a person, how the result is measured.
• Run scheduled loads from accounting systems, files and websites with checks, and reconcile with the source after every load.
• Measure the effect: how many duplicates, gaps and errors are gone and what that gave the company in money.

Who we are looking for

• Experience managing master data in a large company: reference lists, matching, stewardship, data quality.
• Confident SQL and Python; PostgreSQL in daily work, load orchestration (Prefect, Airflow or similar).
• Matching and cleaning tools (Splink, dedupe or similar) and a habit of measuring accuracy.
• Language models as a working tool: classification, extraction, reconciliation — with measured quality, not by eye.
• Russian or English for work; Lithuanian and Bulgarian are a plus.

Software Engineer, applications

You keep our programs running and make them more resilient. Code is written by people and by AI agents; you make sure it works in production.

What you will do

• Investigate defects and failures in our applications: web in TypeScript and Next.js, services in Python, PostgreSQL.
• Make programs resilient: tests, error monitoring, checks before release, deployment from main to the machines.
• Review and correct code written by AI agents: review, boundaries, checks, so that a change does not break its neighbors.
• Maintain shared parts — login, search, design, and model kits — so that an edit in a kit reaches all programs.
• Keep infrastructure as code: Ansible, containers, CI in GitHub.

Who we are looking for

• Five or more years building web applications and services; TypeScript and Python in production, PostgreSQL.
• Experience stabilizing live systems: you fixed what kept failing and made sure it stopped failing.
• A habit of checks: tests, CI, review, error monitoring.
• The ability to work with AI agents as a tool: set the task, verify the result, never take it on trust.
• Russian or English for work.
