We’re TonTech — a team of technical experts supported by the TON Foundation and powered by TOP, which supports developers building on the TON Blockchain. We provide a comprehensive suite of tools and services for developers working on TON Blockchain, making it easier to build and deploy smart contracts and decentralized applications.

We’re looking for a Software Engineer to join our core SDK and testing platform team. You’ll help design and develop cross-platform tools that empower developers to integrate TON technology faster and more reliably across web and mobile environments. Your work will directly impact the quality and scalability of the TON developer ecosystem.

Responsibilities:

• Develop and maintain SDKs and automation frameworks for Web, iOS, Android, and React Native platforms.
• Build systems for automated end-to-end testing of Wallet Kit and other TON SDKs.
• Ensure high-quality test coverage and performance across multiple platforms.
• Design and implement architecture improvements for testing and integration platforms (e.g., proxy-backend, API access management).
• Collaborate with developers, QA engineers, and product teams to improve reliability and speed of test runs.
• Investigate and optimize parallel execution and isolation of test cases.
• Maintain clean, efficient, and well-documented TypeScript-based code for both backend (NestJS, Node.js) and frontend (React).
• Contribute to continuous improvement of automation tools and SDK usability.

Requirements:

• 5+ years of experience in software development or QA automation.
• Strong knowledge of TypeScript (preferred), with practical experience in React, Node.js, or NestJS.
• Experience building or testing SDKs, developer tools, or APIs.
• Understanding of automated testing frameworks and CI/CD environments (e.g., Playwright, Allure).
• Familiarity with cross-platform development and mobile testing (iOS, Android).
• Knowledge of blockchain technologies or experience testing blockchain-based products is a plus.
• Strong sense of ownership, attention to detail, and ability to deliver quality results fast.

Nice-to-haves

• Web3/TON exposure including wallet integration, key management, signing flows, TON Connect protocol, and token/NFT handling.
• Monorepo tooling experience including workspace management, shared packages, versioning strategies, and cross-platform testing frameworks.
• Open-source maintenance including semantic versioning, changelog management, issue triage, community engagement, and telemetry/analytics for SDKs.

Why it is a fantastic opportunity:

• Our business is growing at an exponential scale.
• Non-bureaucratic management that focuses on results.
• Regular performance reviews to assess your progress.
• Remote setup with access to our hubs in Dubai, Yerevan, London and Belgrade.
• Compensation for medical expenses.
