Job summary

EPAM Systems, Inc. in Warsaw seeks a Senior AI-Native Full-Stack Software Engineer to industrialize AI prototypes into production-grade services. You will integrate agentic systems on Azure and build end-to-end production solutions with Python, Java Spring Boot, and TypeScript/Angular.

Responsibilities include establishing eval harnesses, building guardrails, and ensuring CI/CD, observability, and cost-aware design across the stack. This role requires office presence in Warsaw 3 days weekly.

Qualifications

• 5+ years of experience shipping LLM/agentic systems in production.
• Proficiency in Python, Java Spring Boot, and TypeScript/Angular.
• Expertise in Azure PaaS, Azure AI Foundry, and Azure OpenAI services.
• Knowledge of agentic frameworks, vector databases, and knowledge graphs.

Responsibilities

• Industrialize prototypes into production services on Azure AI Foundry and Azure OpenAI.
• Build agentic systems using orchestration frameworks, RAG pipelines, vector databases, knowledge graphs, and MCP-based tool integration.
• Establish the eval harness first, with golden sets, regression evals, and guardrail tests wired into CI to measure quality on every change.
• Engineer guardrails including input/output filtering, grounding and citation, PII protection, rate limits, and human escalation paths.
• Deliver full-stack solutions across Python, Java Spring Boot services, and TypeScript/Angular front ends without relying on separate ownership layers.
• Run production engineering end-to-end, covering CI/CD, observability with traces on every LLM call, and cost and latency management.
• Absorb model-version churn by design, ensuring systems remain resilient as underlying models evolve.
• Build security and compliance into the system, respecting data classification boundaries in prompts, stores, and logs, externalizing secrets, and ensuring every AI decision is auditable.
• Iterate from real usage through hypercare, tuning, and fixes based on evidence, then package successful patterns for future use.
