Senior Full Stack Engineer (Azure/Databricks, GenAI/LLM)
Contract role in Krakow for a senior full-stack engineer who can own end-to-end delivery: gather requirements from business users, perform business/data analysis, design architecture, build and deploy solutions, and support testing/validation and release. The stack centers on Azure with Databricks/Spark/Delta Lake and strong API/integration work, plus GenAI/LLM application development (e.g., OpenAI APIs) for use cases like summarisation and categorisation. Strong DevOps/CI tooling exposure (GitLab, Docker/registries, Nexus), security (Azure AD SSO/SAML, managed identities, Vault), monitoring (Azure Monitor/Log Analytics), and test automation (Cucumber/JUnit/Mockito, API/E2E testing) are expected.
