Job summary

Sii Poland in Szczecin is seeking an experienced software/ML engineer to build AI systems that run in production. You will write Python, connect cloud services, and tackle data quality, latency, evaluation, and deployment challenges.

You’ll work across the AI stack, integrating LLMs, training models, and maintaining production-grade pipelines on Azure, AWS, or GCP. The role offers strong growth and collaboration with AI architects and data engineers.

Qualifications

• At least 4 years in software or ML engineering, with hands-on experience shipping AI/ML systems to production
• Strong Python skills — not just scripting, but writing maintainable, tested code for production services
• Practical experience with AI/ML frameworks such as LangChain, LangGraph, Semantic Kernel, or equivalent
• Working knowledge of at least one major cloud platform (Azure, AWS, or GCP) and its AI/ML services
• Experience with vector databases, embedding models, and retrieval systems in real-world applications
• Familiarity with MLOps fundamentals: model versioning, experiment tracking, CI/CD for ML, and monitoring
• Ability to work autonomously while collaborating effectively with architects, data engineers, and product teams
• Fluent English (both written and spoken)
• Fluent Polish required
• Residing in Poland required

Responsibilities

• Build and deploy knowledge-grounded AI systems end-to-end: data ingestion, chunking, embedding pipelines, retrieval logic, re-ranking, and response generation
• Develop agentic applications — tool integrations, planning loops, memory management, guardrails — using frameworks like LangGraph, LangChain, Semantic Kernel, or equivalent
• Implement and maintain ML pipelines for classical use cases: prediction, classification, recommendation, and optimization models
• Deploy and optimize model serving infrastructure: API endpoints, batching, caching, GPU utilization, and cost management across cloud environments
• Write clean, tested, production-grade Python — not prototype code that someone else has to rewrite
• Build evaluation and monitoring pipelines: automated quality checks, drift detection, latency tracking, and human-in-the-loop feedback loops
• Work with cloud-native AI services on at least one major platform (Azure, AWS, or GCP) to implement scalable solutions
• Collaborate with AI Architects on technical design and with data engineers on data availability and quality
