Job summary

Software Mind in Kraków is hiring a data software engineer to join client data science and product teams. You will productionize Lovable prototypes into secure services on Google Cloud, build data feeds, and connect systems to the canonical data layer.

The role is autonomous with a varied project roadmap and strong emphasis on security and documentation. You’ll own end-to-end service delivery from deployment to monitoring, including conformance with IAM and audit requirements, while

Qualifications

• 4–7 years of hands-on commercial software engineering experience.
• Strong production Python skills across services and data pipelines, including testing and CI/CD.
• In-depth cloud experience (compute, managed databases, serverless, IAM), ideally on GCP, though AWS or Azure experience also counts.
• Full-stack range, strongest on APIs and the middle layer, with the ability to adjust a React/TypeScript front end without a designer.
• Data engineering experience: ingestion from APIs, databases and file extracts, orchestration (Airflow preferred) and schema design for SQL and ideally NoSQL databases.
• Proven experience taking prototypes or AI-generated code to production and owning a service end to end, including deployment, monitoring and documentation.
• Hands-on experience securing your own services: authentication, least-privilege IAM, secrets handling, input validation, audit logging, dependency hygiene, and secure document storage and retention
• Autonomy and commercial awareness: you handle unclear briefs without hand-holding, get up to speed quickly on wide, undocumented tables and unfamiliar systems, and anticipate what users need

Responsibilities

• Turn internal apps prototyped in Lovable into secure, production-grade services on Cloud Run.
• Build backends and middle layers with authentication, audit trails and secure document storage.
• Build and orchestrate data feeds connecting business systems to the canonical data layer, dashboards and planning tools like Pigment and Anaplan.
• Automate recurring reporting and analysis, including scheduled data centralisation and quarterly metrics with manual overlays.
• Own the security of everything you ship, since there is no separate InfoSec function.
• Provide technical review of AI Skills used by business teams.
• Document your work as you go (READMEs, runbooks, architecture notes) so others can maintain it.
• Explain trade-offs to non-technical stakeholders, flag technical risks and sequencing concerns to the sponsor, and decline scope that belongs to other teams
