AI Engineer (Middle+) for a Product IT Company

Location and format: Remote within Russia, CIS Format: Full-time Salary: 300,000 – 400,000 RUB/month

We are looking for an AI Engineer to strengthen the technical team. We need a practitioner — someone who knows how to integrate LLM capabilities into a real product and takes responsibility for the result.

Your main task will be to build a reliable and secure layer of services that powers the AI functions within the platform: from text processing to analyzing large data arrays.

What you will be doing: — RAG and Search: configuring and optimizing hybrid search in knowledge bases (semantic + keywords), working with chunking strategies, ranking, and testing the quality of responses. — Data Security: implementing anonymization tools (PII/NER) before sending data to external LLM providers, building an audit trail for AI actions. — Dialogue Analytics: automatic tagging, evaluating dialogue quality, generating reports based on customer data. — Integrations: building secure interfaces between AI components and external databases, CRM systems, and providers (OpenAI, YandexGPT, GigaChat). — Data Processing: implementing solutions for analyzing text and voice communications (transcription, tagging, classification). — Optimization: monitoring token costs, latency, and participating in the development of AI infrastructure.

Who we are looking for: — Strong background in backend development (3–5+ years). — Deep understanding of modern LLM systems architecture: RAG, vector databases, orchestration. — Understanding the difference between a chat prototype and a resilient production solution. — Ability to independently implement logic within an existing backend.

Tech Stack: TypeScript, Node.js, NATS, Weaviate (vector database), Langfuse (tracing and Evals), PostHog.

Will be a plus: — Experience with transcription and voice data. — Experience deploying OSS models within a client's perimeter.
