• Radical Transparency. We communicate openly and honestly with each other. Respectful candor is valued over comfortable silence, as we can't afford to miss insights due to fear of speaking up.

• Bias for Action. We believe action produces information. At no more than 20% completion of a project we must have a working prototype to test and iterate on.

• Speed with Purpose. We move with urgency and focus. Slow and expensive usually go together. Good, fast, and cheap outcomes are perfectly achievable through disciplined execution.

• Professional Integrity. We never speak negatively about competitors, partners, vendors, or others. Such behavior reflects insecurity and provides no value.

• Creative Problem-Solving. We value innovative thinking that challenges conventions. The best solution aligns with the task at hand, not necessarily with how things have always been done.

• Team Over Ego. We share both successes and failures collectively. No individual's ego should surpass our commitment to the product and its impact.

• Results Over Hierarchy. We do not care about titles in this company. No politics, no hierarchy. All we care about is winning together.

О нас

Мы - CHATTERN - российский EdTech стартап. Разрабатываем платформу для онлайн-преподавания с интерактивной доской, видеосвязью и инструментами для совместной работы.

Мы любим сложные инженерные задачи и не любим компромиссы с качеством. У нас собственная, кастомизированная архитектура видеосвязи, рассчитанная на множество одновременных медиапотоков, и невероятно продуманный UX, за внешней простотой которого скрывается огромная техническая сложность. А ещё мы изобрели Тетрадную камеру – технологию, не имеющую мировых аналогов, которая исправляет перспективные искажения при съёмке обычной бумажной тетради камерой смартфона, позволяя писать от руки во время онлайн-урока.

Мы иногда шутим, что создали Boeing 747 с дизайном Porsche. За простым и красивым интерфейсом CHATTERN скрывается мощная и очень сложная инженерная система. Да, звучит нескромно. Но мы действительно гордимся своим продуктом.

И у нас есть вполне осязаемые результаты:

• На CHATTERN уже проведено более 3 миллионов уроков.
• В первый год монетизации мы утроили месячную выручку, во второй - удвоили её, и продолжаем расти и ставить амбициозные финансовые цели.

Мы прибыльный стартап, который развивается на собственные средства. У нас нет инвесторов, поэтому нам не грозит закрытие только потому, что инвесторы передумали. Мы сами зарабатываем деньги, сами определяем направление развития и сами отвечаем за результат.

У нас особенная атмосфера. CHATTERN создают и развивают сами основатели, люди из IT, которые не понаслышке знают, как устроен продукт, и сами каждый день над ним работают. Мы говорим с разработчиками на одном языке.

У нас нет начальственного снобизма и дистанции между руководством и командой. Мы общаемся на равных, спорим, обсуждаем идеи, умеем слушать и менять своё мнение. Мы любим экспериментировать и не выпускаем сырые решения только потому, что наступил дедлайн. Наш главный критерий - результат, которым можно гордиться.

Пока IT-рынок обсуждает, сколько программистов можно заменить искусственным интеллектом, у нас прямо противоположная задача - нам нужны новые люди. Мы только формируем инженерную команду. ИИ для нас не способ сокращать разработчиков, а инструмент, позволяющий воплощать ещё более амбициозные идеи.

А ещё у нас необычный просторный офис в центре Самары, больше похожий на стартап из голливудского кино, чем на привычный российский опенспейс. 140 м², бильярдный стол, вид на набережную и круизные пароходы. Работаем в гибридном формате, обычно встречаемся в офисе раз, два в неделю.

И да, мы ищем людей, которые, познакомившись с нами и нашим продуктом, подумают: «Чёрт возьми, они странные, но с ними будет интересно работать!»

Senior Frontend разработчик с опытом Backend и эксплуатации инфраструктуры

Чем предстоит заниматься

1. Разработка новых функций CHATTERN

Основная часть работы - frontend-разработка, прежде всего развитие интерактивной доски.

Это не типовая разработка интерфейсов и форм, а создание сложных интерактивных инструментов. Например:

• Редактор математических формул.
• Интерактивный 3D-симулятор для изучения стереометрии.
• Другие инструменты для преподавателей и учеников, которые появляются в процессе развития продукта.

2. Разработка дополнительных модулей продукта

Самостоятельное проектирование и реализация отдельных fullstack-проектов: frontend, backend, базы данных, API.

Например, разработка личного кабинета для онлайн-школ или маркетплейса для репетиторов.

3. Поддержка инфраструктуры

• Поддержка работоспособности серверной и сетевой инфраструктуры совместно с техническим руководителем.
• Диагностика и устранение технических проблем, в том числе возникающих под нагрузкой.
• Работа с Linux, сборками, библиотеками, зависимостями и развёртыванием приложений.
• Подстраховка технического руководителя во время его отсутствия.

4. Вторая линия технической поддержки

Разбор обращений пользователей, требующих технического вмешательства:

• Проблемы с соединением и работой видеосвязи.
• Ошибки приложения, диагностика и исправление багов.
• Технические проблемы, связанные с оплатой и предоставлением доступа.

Первая линия поддержки самостоятельно отвечает на обычные вопросы пользователей о работе с приложением. Разработчик подключается только к вопросам, которые требуют технической квалификации.

Наш технологический стек

• Frontend: JavaScript, React, Material UI, Fabric.js.
• Backend: Go.
• База данных: PostgreSQL.
• Видеосвязь: WebRTC, Janus.
• Инфраструктура: Linux.

Мы не ожидаем, что кандидат заранее знает весь наш стек. Важнее фундаментальная инженерная подготовка и способность быстро осваивать новые технологии.

Что для нас важно

• Senior-уровень владения JavaScript, включая разработку на чистом JS, без обязательного использования фреймворков.
• Уверенный опыт работы с React.
• Опыт разработки сложных браузерных приложений, понимание архитектуры frontend и браузерных API.
• Полноценный опыт backend-разработки. Язык не принципиален.
• Понимание SQL и принципов работы реляционных баз данных.
• Хорошее знание Linux, понимание сетевого взаимодействия, процессов сборки и развёртывания программ.
• Умение самостоятельно диагностировать сложные технические проблемы, в том числе в незнакомых компонентах системы.
• Способность самостоятельно проектировать и доводить задачи до работающего результата.
• Умение эффективно использовать инструменты ИИ в разработке, сохраняя контроль над качеством и работоспособностью кода.

Для нас особенно важны техническая самостоятельность, инженерная любознательность и способность разбираться в новых технологиях. Нам нужен не специалист по заранее известному списку библиотек, а сильный разработчик, способный решать разнообразные технические задачи.
