Job summary

Sii Poland seeks experienced software/ML engineers to build production AI systems and deploy them across Azure, AWS, or GCP. You’ll write Python, wire cloud infrastructure, and solve data quality, latency, and deployment challenges.

You’ll work across generative and classical AI stacks, integrating LLMs into applications, maintaining scalable ML pipelines, and collaborating with AI Architects and data engineers. Fluency in English and Polish is required.

Qualifications

• 4+ years in software or ML engineering with hands-on experience shipping AI/ML systems to production.
• Strong Python skills—writing maintainable, tested code for production services.
• Practical experience with AI/ML frameworks such as LangChain, LangGraph, Semantic Kernel, or equivalent.

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.
• 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).
• Collaborate with AI Architects on technical design and with data engineers on data availability and quality.
