Senior AI-Native Full-Stack Software Engineer

We are seeking a Senior AI-Native Full-Stack Software Engineer to industrialize AI prototypes into production-grade services, building agentic systems that real users depend on while embedding evaluation, security, and observability into every layer of the stack.

Working from the Warsaw office 3 days per week is required.

Responsibilities

• Industrialize prototypes into production services on Azure AI Foundry and Azure OpenAI, moving from build-ready packs to systems real users depend on within weeks.
• Build agentic systems using orchestration frameworks, RAG pipelines, vector databases, knowledge graphs, and MCP-based tool integration, chosen by need and engineered for change.
• 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.

Requirements

• 5+ years of experience shipping LLM/agentic systems in production with real users, backed by defined eval approaches and demonstrated scale.
• Proficiency in Python, Java Spring Boot, and TypeScript/Angular for full-stack delivery.
• Expertise in Azure PaaS, Azure AI Foundry, and Azure OpenAI services.
• Knowledge of agentic frameworks, vector databases, and knowledge graphs, combined with MCP-based tool integration.
• Skills in prompt and context engineering.
• Background in CI/CD pipelines and observability practices, having operated production systems end-to-end.
• Familiarity with AI-assisted engineering workflows, coding daily with AI agents and demonstrating the workflow live.
• Understanding of evaluation-first development, ensuring no AI capability ships without a measured baseline and regression eval.
• Competency in cost and latency optimization, treating token economics as a core engineering feature.
• Understanding of regulated-environment discipline, including data classification, auditability, and least privilege principles.
• English proficiency at B2 level or higher.
