AI/ML • Senior • Yekaterinburg, Russia • In office, Partially remote, Fully remote • Actively seeking • English: A2
Overview
A practical ML engineer at a senior level who builds end-to-end applied ML systems integrating model training, validation, and production serving. The strongest proven skill is delivering production-ready ML services - evidenced by the training pipelines with GridSearch/CV and the FastAPI backend with async DB, Redis caching, Alembic migrations and monitoring hooks. The public code shows solid applied ML and serving engineering but not low-level efficiency work (quantization/CUDA/Triton), novel research architectures, or large-scale distributed training artifacts.

A practical LLM/RAG-focused engineer at a middle level who produces reliable integration code and ingestion tooling. The strongest proven skill is building RAG ingestion and runtime glue - evidenced by the indexer and embedding-fallback logic in lightrag-kb/index_docs.py. There is little public evidence of custom model training, research depth, performance engineering, or production-grade monitoring in the human-authored artifacts.

The strongest proven skill is implementing a FAISS-backed vector-search microservice and orchestration with FastAPI and autosave/backup logic (PredictOutcomes/faiss_manager/faiss_service.py). There is limited public evidence of production hardening such as CI/CD, structured observability (tracing/metrics), formal DB migrations, or secure secret management.

Overview
I am an AI/ML specialist with a stronger focus on research and experimentation than on production engineering. My main interests include NLP, LLMs, RAG and agentic systems, efficient neural architectures, and simultaneous machine translation. My research experience includes developing and evaluating Transformer-, Mamba-2-, and hybrid architectures for low-latency translation, while my professional experience includes building an AI agent and applied LLM-based solutions. I particularly enjoy formulating hypotheses, designing experiments, analyzing model behavior, and turning research ideas into working prototypes.

The strongest proven skill is engineering resilient, safety-aware LLM orchestration and automation, demonstrated by the cover_letter prompt/regeneration/guardrail logic (ai-job-search-bots/hh-autoapply/cover_letter.py) and the orchestrator/watchdog/queue patterns (ai-job-search-bots/hh-autoapply/main.py and tg_listener.py).

Overview
A backend-focused API engineer at a mid-to-senior level who builds production REST services for an education/assessment platform. The strongest proven skill is designing robust exam/variant APIs with transactional submit logic and idempotency controls, demonstrated in src/examgen/api/routers/variants.py (generate/submit paths, transactional checks and ownership guards). Public code lacks explicit large-scale ops artifacts - e.g., comprehensive caching/invalidation strategy, formal load-testing reports, and cluster-level resiliency patterns are not evidenced.

Overview
Backend engineer (senior) specializing in API-driven microservices and real-time trading components. The strongest proven skill is building resilient service fabrics and RPC/API surfaces, exemplified by the MCP Hub (manager/router/supervisor/plugin design) and a Go-based order book with Redis and Prometheus integration. Public code shows solid architecture and testing for microservices and fintech flows but lacks evidence of long migration chains, formal DB migration/versioning practices and enterprise-grade secret management.

Overview
A pragmatic LLM engineer operating at a conservative senior level (tier_score 4.0) who delivers production-ready LLM integrations and async automation. The strongest proven skill is building LLM-driven document ingestion and comparison pipelines with concrete artifacts in pdf_to_md.process_pdf and extract_from_markdown that implement caching, chunking and schema-guided extraction. What is not evidenced is custom model training, rigorous experiment tracking, quantization or distributed model training and serving.

Overview
A pragmatic generalist developer at a solid junior-to-middle level who builds end-to-end prototype applications combining vision, speech and LLM integrations. The strongest proven skill is practical computer vision and application wiring, evidenced by the VisionService and the image-processing Engine and steps (megabax/ar-ai-assistant/src/vision/detectors.py and megabax/CVContainer/Libraries/Core.py). There is little or no evidence of custom model research, production-grade serving, experiment tracking or measured optimization in public code.

Overview
A practitioner focused on building LLM-driven agent systems and simple RAG pipelines at a middle-engineer level. The strongest proven skill is multi-agent orchestration and integration, evidenced by the StateGraph-based supervisor and agent implementations in agent.ipynb and app/agents.py. There is minimal evidence of model training, evaluation pipelines, production deployment infrastructure, or test coverage in the public code.
