SKELAR — український венчур-білдер, який будує міжнародні tech-бізнеси. Разом із ко-фаундерами збираємо сильні команди, щоб перемагати на глобальних ринках.

Сьогодні в SKELAR десяток бізнесів у різних нішах — від EdTech до маркетплейсів. Це компанії, що потрапляють у рейтинги ТОП-стартапів та продуктових компаній України, займають найвищі щаблі в AppStore та розробляють платформи, якими користуються мільйони людей. А ще про бізнеси SKELAR пишуть TechCrunch, Wired та інші світові медіа.

Пишаємося сильною командою із 1000+ фахівців, які мають круту експертизу й амбітні цілі. Наші люди — найцінніший актив компанії, тож ми обираємо будувати бізнеси разом з найкращими талантами на ринку.

Зараз ми в пошуку Tech Lead / Full-stack у новий бізнес Risora.

Для 76% людей найглибшим болем у житті стає прірва між тим, ким вони є насправді, і тим, ким вони могли б стати. Аби подолати цей розрив, ми створили застосунок — симулятор особистості.

Наша ідея проста: найкращий спосіб змінитись і досягти мети — це відпрацьовувати реальні сценарії, а не просто читати про них. Застосунок бере ваш тип особистості та перетворює його на серію практичних вправ, які показують, як характер визначає вашу ефективність та стосунки. Кожне тренування, кожен вибір і результат формують чітку картину вашого потенціалу.

Ти приєднуєшся як перший інженер — hands-on Full-stack із амбіцією вирости в CTO та ко-фаундера.

Які виклики чекають:

— Будувати iOS-застосунок та веб-платформу end-to-end;

— Покривати весь цикл розробки — архітектура, імплементація, деплой, підтримка;

— Налаштовувати інфраструктуру, CI/CD пайплайни та cloud-середовища (AWS у пріоритеті);

— Інтегрувати AI API та third-party сервіси (OpenAI, аналітика, платіжні провайдери);

— Тісно співпрацювати з дизайном і продуктом, щоб перетворювати ідеї у production-ready фічі;

— Щодня використовувати AI-інструменти розробки (Cursor, Copilot тощо), щоб рухатись швидше і писати кращий код;

— Закладати tech-стандарти, code review процеси та документацію в міру того, як команда росте.

Що для нас важливо:

Must have:

— Сильні навички в розробці бекенду та архітектури або в розробці мобільних застосунків (React Native, Swift або Flutter);

— Hands-on досвід розробки і запуску мобільних застосунків (React Native або Swift);

— Високий рівень AI-флюентності в розробці;

— Copilot або схожі інструменти як частина щоденного workflow;

— Досвід інтеграції AI/LLM API (OpenAI, Anthropic тощо);

— Ownership mindset — береш повну відповідальність за те, що будуєш, а не лише за свої таски;

— Досвід з App Store submission та Apple Developer ecosystem;

Nice to have:

— Бекенд-досвід з Node.js (інші стеки розглядаємо, Node у пріоритеті);

— Досвід роботи з базами даних;

— PostgreSQL або схожою реляційною БД;

— Досвід роботи в стартап-середовищі;

— Досвід побудови consumer-facing або гейміфікованих продуктів;

— Інтерес до психології, behavioral science або personality-driven продуктів.

Що тобі слід знати про SKELAR?

Звісно, що це венчур-білдер. Іншими словами — компанія, яка будує tech-бізнеси в різних нішах та підкорює глобальні ринки.

А ще в нас є благодійний фонд, створений співробітниками компанії — SKELAR foundation. В межах ініціативи створюємо та фінансуємо проєкти, що сприяють подоланню наслідків війни та відновленню України.

Можливості всередині нашого венчур-білдера, завдяки яким можемо круто перформити та досягаємо цілей:

— 10+ команд SKELAR Platform, яка забезпечує операційну ефективність бізнесів: від рекрутингу та технічного оснащення до фінансової та правової архітектури;

— Спільнота фаундерів, які вже запустили не один бізнес та діляться своїм практичним досвідом;

— Внутрішні клуби за професійними напрямками: маркетинг, розробка, фінанси, рекрутинг;

— Тренінги, курси, відвідування конференцій;

— Медичне страхування та корпоративний лікар.

Головне — разом ми будуємо в SKELAR середовище для самореалізації людей.

Більше розповімо на нашій першій зустрічі-знайомстві.

Давай із нами будувати the next big everything!
