Responsibilities

- Trace billing discrepancies (e.g., a missing GCP project ID or a $0.05 variance) across raw CSVs, BigQuery logs, and Python code
- Reverse-engineer and document historical architectural decisions in a decade-old codebase to ensure new fixes improve rather than destabilize the system
- Isolate root causes within complex, interconnected systems to provide long-term fixes rather than surface-level patches
- Collaborate directly with the Finance team to translate business logic into automated technical solutions
- Execute the monthly invoicing run
- Systematically identify manual checks and "spreadsheet-based" processes and replace them with scalable, automated architectural solutions, like autonomous AI agents and robust code
- Independently resolve bugs across the entire stack

- Expert at backend scripting and data logic in Python
- Proficient with GCP: BigQuery (SQL), Datastore, and App Engine
- Familiarity with Vue.js/Nuxt.js to handle full-stack resolutions
- Understanding of VAT, VIES compliance, revenue accounts, and accounting dimensions
- Must be fluent in Czech or Slovak and English
- Takes pride in "owning" the system
- Patient and curious enough to dig into legacy code and "boring" data until the truth is found
- Designs AI-driven processes to scan logs and history for anomalies
