Pragmile Sp. z o.o.
We’re a software house passionate about building solutions that change how our clients use data and artificial intelligence. For over 9 years, we’ve been developing innovative AI-driven products such as InfraSenses and SolarSpy — not just using ready-made tools, but also building machine learning models from scratch.We are looking for an experienced Data Science Lead to design and deploy enterprise-grade Generative AI systems for our client in the insurance industry. The ideal candidate will drive innovation in LLM orchestration, multimodal AI architectures, and scalable AI/ML pipelines, owning the full lifecycle from research to production. This is a hands-on technical leadership role, combining individual contribution with mentoring and guiding junior developers.
Key Responsibilities:
Lead end-to-end projects in Generative AI and Large Language Models (LLMs) — from research to production
Architect multi-LLM systems (e.g., Mixture-of-Experts, LLM routing) for cost and performance optimization
Design GPU/TPU-optimized training pipelines for billion-parameter models using FSDP and DeepSpeed
Build multi-cloud GenAI platforms (Azure OpenAI, GCP Vertex AI, AWS Bedrock) with unified MLOps
Ensure enterprise-grade security and data compliance (VPC peering, private endpoints, data residency)
Develop and implement AI governance frameworks – model cards, drift monitoring, red-teaming
Drive innovation through agentic workflows, synthetic data generation, and real-time fine-tuning
Collaborate with leadership to define AI roadmaps and ROI metrics for business impact
Mentor and guide data scientists and ML engineers, fostering technical excellence and innovation
Qualifications: 8+ years in ML (2+ in GenAI), proficiency in Python, PyTorch, TensorFlow (TFX), and experience with Azure / GCP AI platforms
What We’re Looking For:
Proven experience delivering cloud-based AI solutions with Azure OpenAI and GCP Vertex AI (including MLOps pipelines and multimodal models).
Strong hands-on background in LLM evaluation, optimization, and scaling on platforms like Gemini and TPU v5 Pods.
Demonstrated success in automation projects that drove measurable cost reductions.
Experience building RAG systems with hybrid (vector + lexical) search and dynamic data hydration.
Solid understanding of AI compliance and governance, especially in regulated industries (healthcare, finance).
Proficiency in Python, PyTorch, and TensorFlow, with expertise in large-scale model deployment.
A strategic and collaborative mindset — combining technical leadership with business impact.
Preferred Qualifications Additions:
Certifications in cloud-based AI:
Microsoft Certified: Azure AI Engineer Associate
Google Cloud Professional Machine Learning Engineer
Experience with hybrid or multi-cloud GenAI deployments – e.g., training models on GCP TPUs and serving them via Azure endpoints.
Familiarity with best practices for scalability, security, and cost optimization in cloud-based AI/ML environments.
What We Offer
The opportunity to lead cutting-edge Generative AI and Data Science projects for a leading client in the insurance industry.
A chance to shape AI strategy and architecture in enterprise-scale environments.
Collaboration with a team of experienced AI/ML and cloud engineering experts, fostering knowledge sharing and innovation.
A training budget to support your technical and professional development
Private medical care and co-financing of a sports card
Flexible working hours and the option to work fully remotely
