Job summary

Sii Poland in Warszawa is seeking an experienced AI Architect to bridge prototype and production. You will design solutions, estimate effort, and stay involved to ensure delivery.

You will work across generative and classical AI pipelines, engage with clients, scope projects, and shape proposals, with fluency in Azure, AWS, or GCP. The role emphasizes hands-on leadership and architecture excellence.

Qualifications

• At least 10 years in software/data/ML engineering, with at least 3 years focused on AI/ML architecture at scale
• Deep, production-level fluency in at least one major cloud AI ecosystem: Azure, AWS, or GCP
• Experience in client-facing roles — comfortable leading technical workshops and presenting to both C-level and engineering audiences
• Ability to scope and budget AI projects, including cloud cost modeling, team sizing, and delivery planning
• Strong hands-on skills in Python and practical experience with AI/ML frameworks such as LangChain, LangGraph, Semantic Kernel, or equivalent
• Practical experience building knowledge-grounded AI systems and agent architectures in production — not just prototypes
• Solid understanding of transformer architectures and how they affect system design decisions (context windows, latency, cost)
• Fluent English, both written and spoken
• Fluent Polish required
• Residing in Poland required

Responsibilities

• Lead client-facing engagements — discovery sessions, technical workshops, architecture presentations — and translate business problems into well-defined AI solution specifications
• Analyze RFP/RFI documents, assess feasibility, and build technical proposals including architecture diagrams, delivery timelines, team composition, and cost breakdowns
• Scope and estimate AI projects end-to-end — from data readiness and infrastructure needs through cloud costs and ongoing operational expenses
• Design end-to-end architectures for generative and classical AI systems: knowledge-grounded AI, agentic workflows, multi-model orchestration, and hybrid search solutions
• Make and defend technology choices — foundation models, vector databases, orchestration frameworks, inference infrastructure — matching each to the problem, not the hype
• Define MLOps/LLMOps practices and data pipelines: CI/CD for models and prompts, evaluation pipelines, chunking strategies, embedding generation, and drift monitoring
• Lead technical design reviews, produce architecture decision records, and mentor engineers on AI engineering best practices
