GuLi — це команда 15+ web3-інженерів та тестувальників, яка виросла у міжнародну студію повного циклу. Ми не лише перевіряємо чужі рішення, а й розробляємо власні web3-продукти — від смарт-контрактів до фронтенд-dApp-ів.
Чим займаємося
- Product Lab — створюємо DeFi-сервіси, iGaming, NFT-платформи та інфраструктурні модулі.
- QA & Audit — глибоке мануальне тестування, автотести й on-chain перевірки безпеки.
- Tooling — пишемо інхаус-фреймворки й боти для автоматизації тестнетів і моніторингу.
Чому до нас?
- Власна академія — безкоштовно навчаємо product-та QA-інженерів.
- Бонуси за баги і фічі — преміюємо як за критичні знахідки, так і за успішні релізи.
- Кар'єрний ліфт — прозора матриця росту від джуна до product lead.
- Remote-first — синхронізуємо 3 країни в одному ритмі.
GuLi перетворює ідеї на готові decentralised-продукти й гарантує їхню безпеку. Приєднуйся, якщо хочеш будувати та тестувати Web3 на найвищому рівні.

Middle Browser Game Developer (TypeScript + WebGL, Web3 Events) to $5000

Our...We’re a Web3 game studio creating fast-paced, technically refined games with transparent mechanics and well-crafted logic. We work with blockchain infrastructure, blending game development, decentralized technologies, and modern product design. Our mission is to deliver games that are simple to use yet rich in depth, built for a global audience.
What you’ll do- Build browser games (Canvas/WebGL) end-to-end: state machine, animations, assets, sound hooks.
- Wire the client to Web3 triggers: subscribe to contract events via WS, handle pending vs confirmed, finality and rare reorgs (idempotent handlers).
- Keep 60+ FPS on desktop, solid mobile performance (asset atlases, batching, Workers).
- Integrate with Next.js API routes (or a tiny Node service) for caching/retries.
- Cover core logic with tests (math, payouts caps, events pipeline).
Stack
- TypeScript, React/Next.js (game page rendered client-side), Canvas/WebGL (Pixi/Phaser/Three).
- WebSockets, viem/ethers, ABI/log decoding.
- Node.js; Redis is a plus.
Nice to have
- Spine/DragonBones, VFX/shaders (GLSL) or 3D pre-renders.
- VRF/Entropy understanding (Chainlink, Pyth).
- RTP/probability, basic Solidity/Foundry (read contracts, events).
Why join
- Real ownership of features, no bureaucracy.
- Remote-first, tight feedback loop, fast decisions.
- Impact: thousands of live rounds weekly, measurable results.

You will
- Design and ship EVM contracts for slot mechanics, round lifecycle/settlement, a PlayHub (registry/custody/limits), and rewards (referrals, quests, rakeback).
- Integrate secure randomness (VRF / Pyth Entropy / commit-reveal) and expose clean events for realtime clients/indexers.
- Keep security/gas tight: CEI, pull-over-push, access control, pausability, exposure caps.
Write real tests in Foundry (units + a few properties/invariants/fuzz).
Must-have
- 2+ yrs Solidity, 2+ production deployments you owned.
- Event-driven design (ordering, dedup by (txHash, logIndex), finality/reorg awareness).
- Experience with pro-rata distributions/claims (rounding, dust control).
Gas & security literacy (custom errors, packing, immutables; reentrancy/MEV/oracle basics).
Nice to have
- Slot math (RTP/volatility tuning), jackpots, reward streaming/vesting.
- UUPS/EIP-1967 upgrades, EIP-712/permit, The Graph/Subsquid.
- VRF/Entropy in production.
