NextCRM — продуктова CRM для e-commerce (Prom.ua, Rozetka, Horoshop, Instagram-магазини). Керуємо замовленнями, клієнтами, складом, інтеграціями та автоматизаціями для українських продавців.

Шукаємо сильного Python/Django-розробника, який прийде як друга ключова людина в бекенді — не "ще один розробник", а партнер до нашого Senior-бекендера по архітектурних рішеннях і критичних частинах системи.

Що будеш робити:

• Розробляти та підтримувати бекенд CRM на Django + DRF + PostgreSQL
• Працювати з Celery (асинхронні задачі, черги, планувальники) і Redis
• Будувати та підтримувати інтеграції з зовнішніми API: маркетплейси, логістика, платежі, ПРРО
• Оптимізувати продуктивність (N+1, індекси, кеш, bulk-операції)
• Брати участь в архітектурних рішеннях — ти не "виконуєш таски", ти впливаєш на те, як продукт росте
• Працювати з інфрою (Docker, CI/CD, Hetzner) — не як девопс, а щоб розуміти, куди катиться твій код

Що для нас важливо:

• 4+ років комерційного досвіду з Python
• Сильний Django + DRF (ORM, міграції, querysets, сигнали, middleware)
• Досвід з PostgreSQL (складні запити, індекси, оптимізація)
• Практика з Celery + Redis — не просто "бачив", а реально робив задачі з чергами
• Досвід побудови інтеграцій через REST API (OAuth, вебхуки, rate limits, idempotency)
• Базові DevOps-навички: Docker, docker-compose, CI/CD (GitHub Actions), робота з VPS (Hetzner/AWS)
• Вміння аргументувати технічні рішення і відстоювати їх

Буде великим плюсом:

• Досвід з українськими інтеграціями: Prom.ua, Rozetka, Нова Пошта, Monobank, Checkbox ПРРО, Horoshop
• Досвід з SaaS-продуктами або CRM/ERP
• Робота з моніторингом і алертингом (Sentry, Prometheus)
• Досвід з WebSocket / real-time оновленнями

Наш стек: Django, DRF, Celery, PostgreSQL, Redis, Docker, Caddy, Cloudflare R2, Hetzner, Sentry

Чому тобі може бути цікаво:

• Продукт, а не аутсорс — ти бачиш, як твій код впливає на реальних клієнтів
• Вплив на архітектуру — не спадщина "так історично склалось", а простір щоб зробити правильно
• Швидкі рішення, без бюрократії — ти говориш напряму з CEO і product-командою
• Ринок України — продукт, який ти сам можеш використовувати і розуміти
• Віддалено, повна зайнятість, гнучкий графік

Як відгукнутись: коротко (4-6 речень) опиши свій досвід з Django + Celery та одну найскладнішу інтеграцію, яку ти робив — що було найважчим і як вирішив.
