Hire Offshore Python / Data Science Developers in Poland 🇵🇱

Our Python / Data Science candidates go through model-building assessments — not just theory questions. We test data pipeline architecture, feature engineering judgment, model evaluation methodology, and deployment readiness covering Pandas, NumPy, Scikit-learn. Candidates demonstrate their approach to a real ML problem: data exploration, model selection, hyperparameter tuning, and production monitoring. We also verify certifications such as AWS ML Specialty and Google ML Engineer. We specifically filter for candidates who've shipped ML to production, not just trained models in notebooks.

All our Python / Data Science developers are based in India and work schedules that provide 4-6 hours of daily overlap with US, UK, or Australian business hours. This covers standups, code reviews, pair programming, and stakeholder meetings. Complex development work happens during their extended hours, meaning you review pull requests each morning with minimal wait time. We use Jupyter, MLflow, Airflow for asynchronous collaboration and handoffs. We've optimized this cadence across hundreds of engagements.

Every engagement is covered by a comprehensive NDA, IP assignment agreement, and data security protocols. All code, designs, and deliverables created by your Python / Data Science developer are your property — full IP assignment, no exceptions. Access to Jupyter, MLflow, Airflow and other client systems is managed through role-based permissions. Our infrastructure includes VPN-only access to client environments, endpoint security on all workstations, and we can accommodate SOC 2, HIPAA, or other compliance frameworks. Background verification is standard for all candidates.

We offer a free replacement guarantee. If your Python / Data Science developer isn't meeting expectations, tell us and we'll source a replacement with proven expertise in Pandas, NumPy, Scikit-learn within 5 business days at no additional cost. The transition includes a structured handover: documentation of in-progress work, codebase walkthrough with the new resource, and overlap period where both are available. The replacement will be pre-screened for experience in ML Pipeline Development, Predictive Analytics, NLP & Text Analytics. In practice, we rarely need replacements — our vetting process has a 95%+ retention rate past the first 90 days.

From your initial brief to an onboarded Python / Data Science developer typically takes 8-10 business days. We deliver 3-5 pre-vetted profiles with experience in Pandas, NumPy, Scikit-learn within 48 hours. You interview your shortlist, and once selected, onboarding covers environment setup, codebase walkthrough, tooling access, and first sprint planning. Most Python / Data Science developers submit their first meaningful pull request within the first week. Our candidates are experienced in ML Pipeline Development, Predictive Analytics, NLP & Text Analytics use cases.

We offer three engagement models: (1) Dedicated Resource — a full-time Python / Data Science expert specializing in Pandas, NumPy, Scikit-learn works exclusively on your project with 40 hrs/week, daily standups, and direct communication covering areas like ML Pipeline Development, Predictive Analytics, NLP & Text Analytics. (2) Team Extension — a managed pod (2-10 people) with tech lead, developers, QA, and optional PM for sprint-aligned delivery. (3) Project-Based — fixed scope with milestone delivery, full PM oversight, and UAT. Most clients start with a dedicated resource and scale to a team as the project grows.

Your monthly rate covers the developer's dedicated time (40 hrs/week for full-time), equipment and workstation, HR management, time tracking, and our managed services layer — which includes onboarding support, performance reviews, communication facilitation, and admin overhead. There are no hidden costs. Rate differences between seniority levels reflect experience depth in Python / Data Science specifically, not just years in the industry. Rate differences also reflect certification depth — AWS ML Specialty and Google ML Engineer certified developers may be priced at the higher end.

Yes. Our Python / Data Science developers hold certifications including AWS ML Specialty, Google ML Engineer, TensorFlow Developer Certificate. While ML certifications demonstrate foundational knowledge, we weight production experience more heavily — training models in courses is different from deploying and monitoring them in production.
