Jobs at Djinni

We build AI-powered consumer apps. Our first product, Goodie AI, is a food analysis app live on both app stores, has reached 100K downloads in 6 months with 4.9 rating, and 100M+ views on TikTok, and is now heading towards an acquisition. 

Now we're scaling that playbook into a portfolio of new apps across different verticals. Same approach across multiple bets: AI-native and mobile-first.
 

  The Role
 

  You'll be our first engineering hire and a co-builder across everything we launch. This isn't a single-product job. You'll help us ideate,

  prototype, and ship multiple new apps, picking the right stack for each, building the first version, and getting it into users' hands. Some

  will be quick experiments. Some will become real businesses. You'll be in the room for all of it.

  What You'll Do

  - Go from idea to shipped product 

  - Make foundational architecture and technology decisions for new apps

  - Build full-stack: mobile frontends, serverless backends, AI integrations

  - Own the entire lifecycle: prototype, launch, iterate, scale

  - Work directly with the founders to shape product direction

  What You Bring

  Must-have:

  - Strong TypeScript across the stack

  - Deep experience with React Native + Expo or willingness to work in mobile

  - Proficiency with serverless backends (Supabase, Firebase, or similar)

  - Hands-on experience with LLM/AI APIs — prompt engineering, structured outputs, building AI-powered features

  - You've shipped products to real users — side projects, startups, whatever. You know what it takes end-to-end.

  - Thrives in ambiguity. You don't need a spec — you need a problem.

  Strong plus:

  - Experience with mobile monetization (subscriptions, paywalls, RevenueCat, Stripe)

  - Familiarity with mobile growth & analytics (attribution, A/B testing, product analytics)

  - App Store and Google Play submission and release management

  - Background building multi-language / international products

  Nice-to-have:

  - Experience in health, nutrition, fitness, or consumer AI

  - Eye for design and UX. You can build something that looks good without a designer in the room

  - Prior founding or early-stage startup experience

  What We Offer

  - Founding-level equity

  - Real influence over what gets built and how

  - A team that's already proven it can ship 

  - The chance to build multiple products, not maintain one

• Monitor provider performance and recommend improvements to approval rates, reliability, and cost efficiency.
  
   

Risk, Fraud, and Crypto Controls
 

• Monitor payment activity and player behaviour for fraud patterns, including multi-accounting, bonus abuse, account takeover, payment-method abuse, and withdrawal fraud.
• Participate in developing fraud-detection methodologies, risk policies, velocity checks, approval tiers, and escalation logic.
• Monitor crypto transactions using tx hashes, block explorers, wallet-screening and transaction monitoring tools; investigate crypto-processing issues.
• Support dispute and chargeback handling for non-crypto payment methods where applicable.
  
   

Customer Communication and Support

What We Offer

• Competitive salary with a transparent bonus system tied to MQL/SQLs and business results.

Ми — швидкозростаюча фінтех-компанія, і шукаємо людину, яка візьме повний цикл роботи з клієнтською базою у свої руки. Не виконавця завдань, а власника напряму: від стратегії до цифр на дашборді.

Якщо ти знаєш, чим «гаряча» база відрізняється від «холодної», вмієш будувати сценарії реактивації і не боїшся відповідальності за результат — читай далі.

ЩО ТИ БУДЕШ РОБИТИ:
— Формувати тижневі та місячні плани комунікацій для підтримки активності бази
— Розробляти стратегію «дожиму» на всіх етапах воронки: від покинутої заявки до реактивації лояльних клієнтів
— Сегментувати базу в CRM за тригерами: давність останнього входу, кількість закритих кредитів, час без контакту
— Налаштовувати тригерні ланцюжки та проводити ручні розсилки — акційні пропозиції, тестування гіпотез
— Регулярно оновлювати шаблони та альфа-імена, щоб комунікації не «вигорали»
— Відстежувати ефективність на кожному кроці: від доставки повідомлення до цільової конверсії

КОГО МИ ШУКАЄМО:
— 2+ роки на позиції CRM / Retention / Lifecycle Manager — бажано у Fintech, МФО або iGaming
— Розумієш різницю між «гарячою» і «холодною» базою та вмієш працювати з обома
— Маєш практичний досвід із CRM-системами та інструментами автоматизації розсилок
— Рахуєш конверсію і робиш висновки — не просто «дивишся на цифри»
— Когорти, A/B тести та аналітичні дашборди — твій звичний інструментарій

МИ ПРОПОНУЄМО:
— Продукт, що реально росте, з вибудуваними процесами — і простір, щоб на них впливати
— Повна автономія та відповідальність за CRM / Retention: твій напрямок, твої рішення
— Швидкі рішення без бюрократії — ідею можна перевірити вже наступного тижня
— Гібридний формат роботи з гнучким графіком
