Senior Software Engineer – Profile Matching Data & AI Platforms, REMOTE WROCŁAW KATOWICE

We are looking for a Senior Software Engineer to lead the design and delivery of a production platform for collecting, matching, enriching, and delivering profile, entity, and content data from multiple sources.
This is a hands-on leadership role. You will shape the architecture, drive technical direction, and own the design of profile/entity matching and LLM/ML systems across the platform, while remaining an active contributor to the codebase.
This Role Is a Strong Fit If You Have
  • strong Python software engineering experience;
  • experience building or maintaining production systems that process multi-source content and profile/entity data;
  • hands-on experience with profile/entity matching: rule-based, fuzzy matching, graph-based approaches, embeddings, and ML;
  • experience designing multi-source data architectures and catalogues, including deduplication and survivorship strategies;
  • practical experience with LLM APIs, prompting, structured outputs, classification, summarisation, or extraction;
  • strong understanding of embeddings, vector similarity, semantic search, clustering, deduplication, and relevance scoring;
  • experience designing LLM/ML-based enrichment and matching systems end to end;
  • ability to make architecture decisions, evaluate technical trade-offs, and own scalability, reliability, and data quality;
  • ability to write clean, testable code, communicate technical decisions clearly, and provide technical leadership/mentoring;
  • experience using AI-assisted development tools while remaining responsible for quality, security, and correctness.
Required Experience
  • 5+ years of experience in Software Engineering, Backend Engineering, Data Engineering, or Platform Engineering, including ownership of architecture and complex integrations;
  • strong commercial experience with Python;
  • experience designing and building profile/entity matching systems (rules, fuzzy matching, graph, embeddings, ML);
  • experience with data-integration pipelines feeding matching and enrichment systems;
  • knowledge of SQL and relational databases, preferably PostgreSQL;
  • experience with Snowflake;
  • experience with Airflow or similar orchestration tools;
  • experience designing systems around LLM APIs — prompting, structured outputs, embeddings, semantic retrieval;
  • experience with automated testing, CI/CD, version control, and code review;
  • strong communication skills, technical leadership experience, and fluent English.
Technology Expectations
Practical experience with several of the following:
  • Python and modern backend or data-processing frameworks;
  • profile/entity matching: rules engines, fuzzy matching, graph-based methods, embeddings, ML models;
  • multi-source data architecture and catalogs, deduplication, and survivorship design;
  • LLM APIs, prompting, structured outputs, classification, and extraction;
  • embeddings, vector databases, semantic search, clustering, and relevance scoring;
  • Airflow or equivalent orchestration tooling;
  • PostgreSQL and Snowflake;
  • data validation, schema evolution, reconciliation, and data-quality monitoring;
  • Docker, cloud infrastructure, CI/CD, and production deployment;
  • AI-assisted development tools such as GitHub Copilot, Claude Code, Cursor, or equivalent;
  • basics of data science and ML modeling applied to entity resolution;
  • MCP / agentic AI approaches.
Nice to have:
  • rate-limit, quota, and API cost/usage budgeting across third-party integrations (e.g., social platforms, video platforms, and similar);
  • observability and SLO design — logs, metrics, dashboards, alerts, health checks;
  • Parquet, object storage, or analytical data platforms;
  • RAG, AI agents, LangChain, LangGraph, or LLM orchestration frameworks.
