This is the job

We are seeking a Senior AI Engineer to spearhead the design and orchestration of intelligent agentic frameworks within our evolving digital ecosystem. This role is a sophisticated blend of generative AI strategy and technical architecture, focused on bridging the gap between high-level reasoning concepts and production-ready engineering.

This is you

• Strong experience designing AI agents and orchestration flows, including tool-use, multi-step reasoning, and delegated logic.

• Hands‑on implementation of prototypes, orchestration logic, and interaction flows (Python / Node.js / notebooks / sandbox tools).

• Proficiency with agentic/LLM frameworks (e.g., Semantic Kernel, LangChain, AutoGen, or similar).

• Solid knowledge of prompt engineering and model behaviour tuning.

• Understanding of retrieval-augmented generation (RAG/CAG) and embedding/vector search principles.

• Ability to define small test sets, run structured checks, and interpret results for actionable improvements.

• Solid grasp of security, privacy, and risk considerations specific to AI (prompt/data handling, AI model security).

• Familiarity with Azure AI components (Azure OpenAI, Cognitive Search, APIM, Service Bus/Event Grid).

• You are fluent in English at a communicative level.

• Czech or Slovak language at an professional level is essential.

This is your role

• Design & Orchestration: Create agent behaviors, reasoning flows, and multi-agent patterns (like planner–executor or routing) for complex workflows.

• Prompt Engineering: Develop and refine secure prompts, system instructions, and behavioral templates to ensure consistent, high-quality reasoning.

• Rapid Prototyping: Build lightweight PoCs and minimal code snippets to validate agent logic and LLM capabilities before production.

• RAG/CAG Development: Construct early-stage retrieval pipelines, focusing on chunking logic, embedding strategies, and context assembly.

• Evaluation & QA: Conduct structured testing for reasoning consistency and tool-use correctness while identifying and mitigating hallucinations.

• Architectural Alignment: Partner with AI/IT architects and delivery engineers to ensure designs are feasible, maintainable, and secure.

• Knowledge Leadership: Share best practices on agentic design and support development teams in adopting LLM-based standards.

• Continuous Learning: Monitor emerging trends in orchestration frameworks and retrieval systems to keep internal standards up to date.

• Documentation: Record design decisions, constraints, and test results to provide actionable recommendations for implementation teams.

• Enablement Focus: Act as a bridge between design and engineering, focusing on validation and technical guidance rather than core application development.

What awaits you at Avenga?

• Pleasant working environment and stable background in one of the largest software development companies

• Space to work independently and creatively with the possibility to implement your own ideas and opportunities to learn new things and approaches

• You have the opportunity to influence your direction in the company

• High quality hardware and software, access to the latest technologies and specific projects

• Opportunities to improve your language skills, we are a major global player

• At Avenga, you'll get quality support in your development thanks to a wide range of internal and external training courses, so you can push the boundaries of your competences

• We offer you benefits such as life insurance and pension contribution, EN/DE/ES lessons, MultiSport card, sick days, meal allowance, lots of company events, offices in Prague Palmovka with quality amenities for lovers of sport, food and coffee, hybrid remote work after mutual agreement, and more
