Ми — Leaply — екосистема взаємопов’язаних цифрових і фізичних продуктів, створена щоб допомагати людям формувати корисні звички та підвищувати якість життя. Ми розробляємо низку B2C-продуктів для глобальних ринків, включаючи США, Tier 1 країни, Європу та інші регіони.

В червні ми запустили новий продукт — веб-платформу для побудови корисних звичок з підписочною моделлю монетизації та performance-first маркетингом з таких каналів як Meta, Google, TikTok.

Ми стартували як стартап у 2024 році й за останні пів року виросли в 10 разів. У 2025-му наша ціль — зрости в 5 разів. Ми вже маємо провалідований попит на продукт та стабільний потік користувачів.

Наша амбітна мета — перетворити наш web-based MVP на повноцінний мобільний застосунок, який фундаментально змінить підхід до того як ми формуємо звички. Щоб перетворити цю візію на реальність – ми збираємо команду з A-payers для того щоб побудувати і розробити застосунок з нуля.

У Leaply ми переосмислюємо класичні кар’єрні шляхи — ми цінуємо вплив більше, ніж посади й процеси. Ми діємо швидко, мислимо масштабно і не обмежуємось рамками своєї ролі, щоб разом будувати наступний український єдиноріг.

Для реалізації цієї амбітної мети ми шукаємо не менш амбітного першого Android-інженера, який зможе:
— Разом з продуктовою командою зібрати до купи концепт першої ітерації застосунку відповідно до бізнес цілей та потреб користувачів;
— Із нуля підібрати технологічний стек і побудувати архітектуру продукту;
— Розробити й зарелізити B2C-застосунок з нуля;
— Працювати з повним циклом ітеративної розробки продукту — від аналізу потреб користувачів до відстеження бізнес-метрик і аналітики.

Що для нас важливо:
— 3+ роки досвіду в розробці Android застосунків;
— Досвід запуску мобільного застосунку Android з нуля;
— Досвід роботи в кросфункціональних командах;
— Глибоке розуміння нативних платформ, їх можливостей і обмежень;
— Проактивне мислення й відповідальність, орієнтація на вирішення бізнес- та користувацьких задач;
— Інтерес до нових технологій і рішень, які покращують продукт і процес розробки;

Буде плюсом:
— Глибоке розуміння принципів user-centered design;
— Досвід підбору та управління інженерною або продуктовою командою;
— Практичний досвід із серверною розробкою.

Ти можеш розраховувати на:
— Конкурентну компенсацію;
— Офіс у Варшаві або Києві з приємними бонусами (обіди, спортзал, медстрахування);
— Повну відповідальність за свій напрямок і вплив на продуктову стратегію;
— Підтримку досвідченої команди з успішними exit’ами;
— Доступ до внутрішніх спільнот у напрямках tech, product, marketing і payments;
— Осмислену місію — Leaply допомагає людям щодня жити краще.
