Шукаю інженера на технічне ядро продукту: бекенд і рендер-пайплайн живого SaaS з генерації відео. Під капотом LLM-оркестрація, Remotion і ffmpeg. Продукт працює і приносить гроші.

Задачі

• Розробка нових можливостей пайплайну від початку до кінця: нові джерела матеріалу, нові типи сцен, редактор перед рендером, вертикальний короткий формат. Спека, реалізація, тести, деплой, перевірка на живому рендері, весь шлях твій
• Оптимізація хмарного GPU-рендеру: продуктивність, вартість, стабільність під навантаженням
• Надійність джоб-пайплайну: коректна поведінка під час збоїв, повернення коштів, відновлення після падінь
• Обробка відео: вхідні файли з різними кодеками та фреймрейтами, нормалізація, склейка, A/V-синхронізація
• LLM у проді: схеми виводу, валідація, обрізані відповіді, вартість токенів
• Рефакторинг основного модуля пайплайну під великим набором тестів, без зміни поведінки

Стек

Python, asyncio, FastAPI, SQLAlchemy, Postgres, pytest

Docker, хмарний GPU-рендер, S3, durable job queues

ffmpeg, headless Chromium, TypeScript/React (Remotion), LLM APIs

Платежі вже інтегровані — питання не в інтеграції, а в тому, щоб нічого не губилося під час збоїв.

Треба

Сильний async-Python. Реальний досвід з ffmpeg. Розподілені системи: ідемпотентність, дедлайни, відновлення після збоїв. Docker і хмарний деплой руками. Звичка писати тести — половина роботи саме про це.

Буде плюсом: LLM у проді, TypeScript достатньо, щоб полагодити Remotion-композицію, Postgres глибше за CRUD.

Умови

Помісячний контракт з продовженням. 

Команда маленька — технічна частина на тобі, працюєш напряму із засновником

Напиши мені про медіа-пайплайни, які ти будував.
