AI/ML • Senior • 20 years • Astana, Kazakhstan • In office, Partially remote, Fully remote
A pragmatic ML/AI engineer with multi-component experience (model serving, RAG, real-time audio/STT/TTS and web APIs) at a senior-but-practical level. The strongest proven skill is building real-time LLM + audio orchestration and memory/RAG infrastructure - evidenced by the MessageProcessor/processing.py audio/queueing logic, memory_v2.py and the FastAPI model-serving ModelManager. Missing or not evidenced are formal statistical methodology, rigorous experiment pipelines, CI-driven reproducibility (DVC/locks) and formal test coverage or A/B evaluation frameworks.

Backend • Senior • Moscow, Russia • Fully remote • English: B2
A Senior-level backend API engineer who primarily builds Python services integrating external systems and LLM tooling. The strongest proven skill is designing and implementing async, concurrent integrations with external APIs and CPU-bound offloads - for example backend/api/user/polygon/archive/uploader.py (PolygonImportClient, semaphore, retries, run_import) and the ProcessPoolExecutor usage for plagiarism checks. There is limited public evidence of large distributed systems tooling (Kafka/streaming), vector-database work, or extensive infra/observability (metrics/tracing) beyond logging and tests.

Mobile • Middle • 12+ years exp • 39 years • Moscow, Russia • Fully remote • Relocation • English: B2
A cross-platform mobile engineer at a lower-middle (junior-to-middle) level who implements small native integrations for hybrid apps. The strongest proven skill is building native Cordova plugin bindings and integrating native SDKs, as shown by ResetFontSize.initialize (Android WebView/WebSettings/main-thread handling) and the RollbarCordova native bindings on both Android and iOS (initialize and sendJsonPayload). There is little evidence of advanced mobile engineering like lifecycle resilience, offline sync, background scheduling, automated tests, or release/CI automation in the public code.

AI/ML • Senior • 4+ years ML exp • Relocation
A senior-level LLM-engineering practitioner focused on trustworthy LLM evaluation, agent workflows, and inference-capacity tooling. The strongest proven skill is building rigorous evaluation and benchmarking pipelines rooted in deterministic validity gates and honest scoring (e.g., scorecard construction in assay/assay/scorecard.py and solver orchestration in assay/assay/solver.py). What is not evidenced is custom model training or novel neural-architecture development—there are analytical and simulation layers but no bespoke training loops or new model implementations in public code.

A capable developer who produces clean, self-contained tooling and educational/game code at a middle (early mid-level) competence. The strongest proven skill is Python CLI/tooling and text-processing, demonstrated by the analyze_lessons.py script (argparse-driven CLI, modular analysis, CSV output and reporting). There is limited evidence of backend system design - no databases, network APIs, scalability patterns or production-grade reliability/observability features are present in the analyzed human-authored files.

AI/ML • Middle • 4+ years exp • 25 years • Moscow, Russia • In office, Partially remote, Fully remote
A generalist C++ developer at a lower-middle (early middle) level who builds multithreaded desktop and systems utilities. The strongest proven skill is concurrent C++ and low-level data-structure work, evidenced by the atomic queue implementation (Labmem-015/two_queues/include/atomic_queue.hpp) and coroutine scaffolding (Labmem-015/two_queues/include/async.hpp). The work shows limited attention to correctness and production hardening - there are unsafe manual allocations, UB-prone pointer arithmetic, race-prone lock usage and no CI/tests or MCU/driver firmware artifacts.

AI engineer (senior-level) focused on document-grounded retrieval and API orchestration for RAG systems. The strongest proven skill is building and integrating a production-minded retrieval stack and service boundary (Python RAG HTTP/gRPC service + Go orchestration) as shown by api/http/app.py and grounded-horticulture_ru/server/rag_chat.go. There is limited public evidence of large-scale distributed systems work like sharding/consensus, measured performance tuning at scale, or an exhaustive cloud IaC/ops pipeline in the analyzed human-authored files.

A pragmatic backend API engineer at a solid middle-to-senior level with repeated evidence of building and testing production HTTP services. The strongest proven skill is backend API and data-layer engineering, demonstrated by layered handlers → services code, sqlx-based queries with batched lookups and transactional flows (examples: services/listing.rs, services/user.rs and replace_profile_links/delete_account tests). The public code shows limited evidence of large-scale distributed architecture, sophisticated caching or formal runtime resilience frameworks beyond pragmatic rate limiting and background tasks.

A backend API engineer at an early senior level who produces well-structured service code with deliberate transaction and concurrency controls. The strongest proven skill is data-layer design and concurrency control (row-level locking, skip_locked, migration history and transactional use-cases) as implemented in create_order.py, related infrastructure models and Alembic migrations. Public code does not show advanced operational artifacts like distributed queuing, caching/invalidation strategies or a multi-service production architecture.

AI/ML • Junior • 7+ years exp • Saint Petersburg, Russia • In office, Partially remote, Fully remote
A pragmatic Rust systems/tooling engineer at a Middle level (approx 3.0/10) who builds CLI-first developer tools and content pipelines. The strongest proven skill is developer tooling and pipeline design - exemplified by loadout/src/main.rs (sync_target), loadout/src/catalog.rs (catalog parsing/resolution) and the integration tests in t3chn/loadout/tests/integration.rs that validate idempotent end-to-end flows. There is no evidence of game-engine work (rendering/shaders/physics), deterministic simulation, or multiplayer/netcode in the human-authored files analyzed; several other files in the tree are AI-authored or boilerplate and were ignored per analysis policy.
