Описание

Web3 Fullstack Engineer Xsolla, Remote Xsolla is a global commerce company with robust tools and services to help developers solve the inherent challenges of the video game industry. From indie to AAA, companies partner with Xsolla to help them fund, distribute, market, and monetize their games. Responsibilities: 🌸Build Seamless Web2 ↔️ Web3 Integration — Design and ship the flows that let users move between traditional accounts/payments and on-chain wallets without friction: custodial and non-custodial wallets, account abstraction, gasless transactions, and fiat on-ramps. 🌸Own the Digital Item Lifecycle — Build the systems behind item mint, ownership, transfer, trading, and redemption — keeping on-chain state and off-chain records consistent, auditable, and fast. 🌸Develop Fullstack Features — Deliver end to end across wallet-connected frontends, backend services, and the smart contract / indexing layer that powers item ownership and turnover. 🌸Model Items & Ownership — Design data models and APIs that represent items uniformly whether they live off-chain, in a custodial wallet, or on-chain, and keep them in sync. 🌸Ensure Reliability of Value Flows — Anything that moves items or money must be correct under failure: idempotency, reconciliation, replay safety, and clear recovery paths. 🌸Integrate Blockchains & Marketplaces — Interact with EVM chains, token standards, indexers, and marketplace/settlement flows; abstract their differences behind clean internal interfaces. 🌸Collaborate Across Teams — Work with product, security, payments, and game-facing teams to turn business needs into well-scoped technical plans, and document decisions so they stand on their own. Nice to Have: 💦Experience building NFT marketplaces, item trading, or secondary-market / settlement systems 💦Familiarity with blockchain indexing tooling (The Graph, custom indexers) and node/RPC infrastructure 💦Experience with account abstraction (ERC-4337), smart wallets, or paymaster/relayer setups 💦Background in payments or fiat on-ramp integration bridging traditional commerce and crypto 💦Experience with non-EVM ecosystems (Solana, etc.) or cross-chain / bridging patterns 💦Familiarity with security and compliance relevant to digital assets: custody, key management, audit logging, KYC/AML touchpoints 💦Contributions to open-source web3, wallet, or tooling projects 💦Hands-on, up-to-date experience with modern AI tools (e.g. Claude, Copilot, Cursor) for code generation, review, and accelerating day-to-day engineering work Apply #engineer #remote
