Що варто знати про SKELAR?
Це венчур-білдер — іншими словами, компанія, яка будує компанії. З нами фаундери створюють consumer-бізнеси, які стають лідерами на глобальних ринках EdTech, Mental health, Petcare, FashionTech та інших.

Скеларівці будують tech-продукти, які здобувають відзнаки від Product Hunt, The Webby Awards та отримують тисячі позитивних відгуків на TrustPilot. Загалом tech-продуктами наших бізнесів користуються 10+ млн людей у світі.

Усе завдяки сильним командам, бо наші спеціалісти — це ключова цінність SKELAR.

Для професійної реалізації ми створили середовище з експертизою та необмеженими можливостями — і шукаємо тих, хто прагне викликів.

Зараз ми в пошуку Data Analyst, щоб разом піднімати планку результату.
Виклики, які чекають на цій ролі:

  • побудова звітності, метрик та впровадження їх у бізнес-процеси;
  • оцінка впливу ініціатив, причинно-наслідковий аналіз змін;
  • дизайн, запуск і оцінка A/B-тестів, прийняття рішень на основі результатів;
  • створення пайплайнів на Dataform та робота з великим об’ємом даних.

Що для нас важливо:

  • впевнене знання SQL;
  • знання Tableau;
  • вміти проводити дослідження з когортно-календарними взаємозв’язками;
  • аналітичне мислення та прагнення до нестандартних рішень;
  • акуратність, увага до деталей;
  • вміння працювати в команді.

Буде перевагою:

  • вміння проводити A/B-тести від генерації гіпотез до закриття;
  • вміння працювати з Dataform та BigQuery.

У SKELAR ми побудували середовище для професійної самореалізації:

  • SKELAR Platform. Це операційне ядро венчур-білдера, що допомагає фаундерам швидше проходити шлях від нуля до одиниці. Так команди бізнесів фокусуються на продукті — а 10+ команд в складі Platform закривають функції Legal, Finance, HR, Admin, Talent Acquisition, Employer Branding, IT та інші.
  • Нетворк та обмін досвідом як частина культури. Серед наших колег — кофаундери, які запустили не один бізнес, а також найсильніші спеціалісти на ринку. Тож ми маємо доступ до необхідної експертизи на відстані витягнутої руки.
  • Ексклюзивна доменна освіта. Ми створили власні навчальні програми для тіммейтів на вибір — від 2-місячної школи для менеджерів-початківців до інтенсивів про AI та професійних клубів з розробки, продакт-менеджменту тощо.
  • Вплив на системну допомогу Україні. Маємо благодійний фонд SKELAR foundation, який створили самі скеларівці — і завдяки кожному співробітнику втілюємо важливі соціальні проєкти. Наприклад, заснували перший у Європі акселератор для ветеранів і формуємо майданчик для підтримки ветеранів на рівні держави.
  • Екосистема для продуктивної роботи. Для скеларівців створені простори, які надихають на результат — з власним спортзалом, скеледромом, зеленими зонами Bali та бібліотеками. У спейсах, де сервіс, безпека та комфорт синхронізовані з темпом зростання команд, отримуємо вау-досвід та працюємо ефективніше.
  • Турбота про щоденний комфорт. Сніданки, обіди, доступ до спортивних тренувань в Києві або часткова компенсація занять у Варшаві, медичне страхування, оплачувані відрядження, якщо специфіка ролі передбачає такі поїздки, корпоративні знижки від партнерів.

Більше розповімо на нашій зустрічі-знайомстві.

Запрошуємо будувати the next big everything у SKELAR разом!
