Working in parallel with the AI Infrastructure Lead, your core mission will be to wrangle, structure, and reconcile complex business and telecom data. You will build the remote pipelines that ultimately feed into the newly established on-premise LLM ecosystem, with periodic travel to Croatia for stakeholder alignment.\n\nKey Responsibilities\n\nETL & Data Pipelines: Design and maintain pipelines to import files from numerous external sources, handling varied and inconsistent spreadsheet or CSV layouts.\n\nData Extraction & Structuring: Parse messy, semi-structured data (LLM-assisted extraction experience is a strong advantage).\n\nReconciliation: Match and validate disparate datasets, configuring tolerance levels, exception handling, and automated difference reports.\n\nTelecom & Billing Processing: Work heavily with pricing lists, tariffs, invoicing, and complex billing systems.\n\nSystem Integration: Write processed data into legacy or in-house systems via staging tables, APIs, or import files.\n\nDatabase Architecture: Manage and optimize large-scale tables in SQL (preferably MariaDB/MySQL).\n\nBusiness Logic & Testing: Implement configurable business rules, approval workflows, and anomaly flags. Write automated tests for various input formats and matching logic regression.\n\nStakeholder Collaboration: Conduct workshops with business users to translate requirements into technical specifications and support user testing phases.\n\nRequirements\n\n4+ years of hands-on experience in Data Engineering, ETL pipelines, and SQL (MariaDB/MySQL).\n\nUpper-Intermediate (B2) or Advanced English to conduct workshops and gather requirements directly from business users.\n\nStrong Plus: Domain experience in Telecom/VoIP, including familiarity with rate sheets, CDRs, dial codes, and ASR/ACD metrics.\n\nProven ability to untangle messy data and build robust reconciliation processes.\n\nAbility to work independently in a parallel track, ensuring data pipelines are production-ready for final AI model integration.\n\nWillingness to occasionally travel to Croatia for team collaboration and business alignment sessions.\n\nWe OFFER:\n\nA fast-paced, highly professional, international team environment with a flat structure and rapid decision-making.\n\nCompetitive compensation packages commensurate with your background and product portfolio.\n\nFlexible, remote-first workflow optimized for seamless global alignment.\n\nMedical Insurance in Ukraine and a Multisport program in Poland.\n\nOffices in Ukraine (Kyiv, Kharkiv) and Poland (Wroclaw) or Remote.\n\nPaid vacation, sick leave, and official holidays.\n\nLegal & Accounting services.\n\nThe company provides all necessary equipment.\n\nEnglish classes and Education reimbursement.","description_format":"text","description_chars":2822,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Health
