Банк Львів - банк для вільних людей! 

У «Близенько» 150 000 покупців щодня, понад 2500 співробітників і Creatio, в якій живуть операційні процеси мережі: задачі й проєкти, погодження, робота з контрагентами, обмін даними з ERP та аналітичним сховищем.

Ми зростаємо і посилюємо технічний напрям навколо Creatio. Шукаємо технічного власника платформи, який очолить її подальший розвиток: усе, що вимагає коду, інтеграцій та рішень про архітектуру.

Ти очолиш внутрішній напрям розробки Creatio. Поруч із тобою працює бізнес-аналітик (тримає вимоги та процеси), а складну кастомізацію та підстраховку ми закриваємо залученою командою партнера-інтегратора. При цьому - справжня технічна свобода: ти сам вирішуєш, як платформа розвивається, без узгодження кожного кроку.

Що робити

• Розвивати нашу Creatio: обʼєкти, бізнес-процеси BPMN, сторінки Freedom UI, права доступу, дашборди;
• Дотримуватися підходу No-code First: розробка на C# - тільки коли штатного функціоналу недостатньо;
• Інтеграції з ERP і сховищем через REST / OData: стійкий обмін з логуванням, retry, захистом від дублювання даних;
• Продакшн: розбір інцидентів, швидкодія БД, оптимізація SQL;
• Релізи й апгрейди версій платформи разом із техпідтримкою вендора;
• Систематизувати технічну документацію: вести реєстр доробок, схеми інтеграцій та runbook — ми цінуємо прозору архітектуру та зрозумілі процеси.

Потрібно

• 2+ роки практичної розробки на Creatio або іншій low-code BPM/CRM платформі;
• C#/.NET та SQL - складні запити й оптимізація;
• Інтеграції через REST / OData.

Плюсом

• JavaScript / Angular для Freedom UI;
• Сертифікація Creatio;
• Досвід у ритейлі або логістиці;
• BPMN за межами Creatio.

Що ми даємо

• Бронювання військовозобов’язаних: офіційне працевлаштування та статус критично важливого підприємства;
• Заробітна плата $2000–2500 (Net), залежно від досвіду;
• 24 дні оплачуваної щорічної відпустки, оплата лікарняного;
• Оплата сертифікації Creatio та навчання в Creatio Academy;
• Надійний тил: партнер-інтегратор залучений на постійній основі для складної експертизи, розбору важких інцидентів та підстраховки на час твоєї відпустки;
• Прямі комунікації: пріоритети беклогу обговорюємо напряму з тобою, без зайвої бюрократії.
• Бонус: знижка 30% на каву, свіжу випічку та продукцію ТМ «Розмаїж»;

Як відбираємо

Без марафону: 30 хвилин розмова → технічне інтервʼю з інженером партнера-інтегратора → практичне завдання → офер. Тиждень-півтора від першого контакту. 

Відгукуйся кнопкою на Djinni — відповідаємо протягом дня.
