Ми працюємо над інноваційними проєктами у сфері AI, зокрема над голосовими агентами на базі LLM, а також у напрямках автоматизації та SaaS. Ми співпрацюємо з командами з США та Великої Британії 🌍 — допомагаємо запускати складні технологічні продукти, автоматизувати процеси та масштабувати бізнес.

У Softcery цінують довіру, ініціативу і здорову автономію. Ми працюємо чесно, прозоро, підтримуємо одне одного та не створюємо зайвих бар'єрів у процесах. Якщо тебе драйвить AI, ти хочеш впливати на продукт і зростати в сильній команді — приєднуйся до нас 💛

Ми шукаємо Full-Stack Developer’a, якому цікаво вирішувати нетривіальні задачі, працювати з сучасним стеком і занурюватись у напрямок AI. Це історія не про типові таски — а про вплив, складні виклики і багато взаємодії з командою. Ти зможеш пропонувати свої ідеї, змінювати процеси і бачити, як твоя робота впливає на успіх.

🎯 Твої майбутні задачі:

• Спілкуватись із командою та стейкхолдерами — ми цінуємо прозорість і швидкий зворотний зв’язок.
• Брати участь в обговореннях і технічних рішеннях — твоя думка важлива з першого дня.
• Ініціювати зміни: покращення в стеку, процесах або архітектурі завжди вітаються.
• Розробляти новий функціонал для клієнтської частини та підтримувати вже реалізоване.
• Оптимізувати перформанс і стабільність — якість коду для нас не формальність.
• Працювати в невеликій команді, де є можливість долучатись не лише до фронту, а й до API та AI-компонентів.

⭐ Що для нас важливо:

• 2+ роки комерційного досвіду з React та Node.js — ти вже впевнено орієнтуєшся у повному стеку.
• Сильне володіння JavaScript та TypeScript — на цьому будується більшість наших рішень.
• Робота з базами даних: як SQL, так і NoSQL — з розумінням, де і що краще застосувати.
• Розуміння принципів Clean Architecture та DDD — нам важливо, щоб рішення були не тільки “робочими”, а й довготривало стійкими.
• Командна гра, ініціативність і відповідальність — у нас немає мікроменеджменту, тому твоя самостійність має значення.
• Досвід інтеграції з AI-сервісами через API (OpenAI, Claude, Gemini тощо) — великий плюс.
• Вільне володіння українською та англійською (Upper-Intermediate+) — бо спілкування з кастомерами — це частина роботи.

💡 Буде перевагою:

• Досвід роботи з AI інструментами, для оптимізації роботи – Cline/Cursor/Windsurf, etc.
• Досвід роботи з LLM, навички Prompt-engineering.
• Досвід з Python.

🌿 Наші benefits:

• Плавний онбординг та чіткі процеси — поступове занурення у процеси та проєкт, щоб ти почувався впевнено з першого дня. Ми працюємо за прозорими, налагодженими процесами, що робить нашу роботу зручною та передбачуваною.
• Гнучкий графік і віддалена робота — вибирай комфортний час і місце для продуктивності.
• Компенсація навчання — покриваємо курси, літературу, заняття з англійської та підписки на AI-інструменти для твого професійного росту.
• Бухгалтерський супровід — ми піклуємося про фінансові питання, щоб ти міг зосередитись на роботі.
• Відпустка та лікарняні — 20 оплачуваних днів відпустки, 12 днів лікарняних на рік, а також 2 оплачувані «period leaves» для жінок щомісяця.
• Вихідний у день народження — святкуй особливий день без зайвих думок про роботу.
• Членство в IT Cluster — можливості для нетворкінгу та професійного розвитку у спільноті.
