Аналитический движок и хранение построены на DuckDB, поиск - на IResearch, нашем собственном C++-движке, который core-команда пилит уже не первый год.\nИщем сильного C++ инженера в core-команду: работать со слоем хранения, исполнением запросов на DuckDB и поисковым движком. Это не «прикрутить фичу сбоку» - это лезть в самое ядро.\nСтек: modern C++, Linux, DuckDB, полнотекстовый и векторный поиск, векторизованное исполнение, колоночное хранение, инвертированные индексы, многопоточность и concurrency, performance optimization, low-level profiling.\nЧем предстоит заниматься\n- Глубоко разбираться в кодовой базе: storage, query engine, поисковый слой. Reverse engineering архитектуры, поиск узких мест, документирование ключевых компонентов\n- Развивать слой на DuckDB: планирование и исполнение запросов, хранение, catalog/store, апстрим-бампы и расширения\n- Развивать свой поисковый движок: инвертированный индекс и columnstore, скоринг (BM25, WAND/MaxScore), векторные индексы (IVF, квантизация), токенизаторы, компрессия постинг-листов\n- Развивать протоколы и коннекторы: foreign servers, форматы и источники (Parquet, Iceberg, CSV, JSON на S3/HDFS), совместимость с ClickHouse/Elasticsearch\n- Профилировать CPU/память/диск, оптимизировать критические участки, гонять бенчмарки (ClickBench, ann-benchmarks, FTS)\n- Писать модульные, интеграционные и нагрузочные тесты, участвовать в SQL-фаззинге и код-ревью\nКого мы ищем\n- Уверенно владеете современным C++\n- От 3 лет системного программирования\n- Сильные алгоритмы, структуры данных, многопоточность и concurrency\n- Есть опыт с высоконагруженными системами\n- Умеете разбираться в сложном чужом коде\n- Понимаете, как работает ОС: память, диск, сеть\nБудет плюсом\n- DuckDB, ClickHouse, Elasticsearch/Lucene\n- Разработка баз данных, поисковых систем или query engines\n- Полнотекстовый поиск / IR (инвертированный индекс, BM25)\n- Векторный поиск / ANN (IVF, HNSW, квантизация)\n- Колоночное хранение, векторизованное исполнение, query planning\nУсловия работы:\n Гибкий подход к началу рабочего дня;\n Возможность гибридного или удалённого формата работы;\n Сильная инженерная команда, у которой есть чему поучиться;\n Реальное влияние на архитектуру продукта, а не тикеты из бэклога;\n ДМС со стоматологией;\n Компенсация спорта;\n Компенсация изучения иностранного языка;\n Корпоративное обучение.","description_format":"text","description_chars":2454,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"Russian","level":"Advanced
