Role Overview

We’re looking for a Blockchain Engineer to work on TON-based backend services and smart contracts. The role focuses on FunC smart contract development, Jettons, and TON infrastructure, with Go and Node.js used for backend services, tooling, testing, and integrations. Solidity is used occasionally for EVM compatibility, but TON / FunC is the primary focus.

What you’ll do

• Develop and maintain backend services and tooling integrated with TON

• Write and maintain smart contracts in FunC

• Work extensively with TON-specific concepts, including asynchronous transactions, high-load environments, and slow shardchains

• Develop and maintain off-chain services, scripts, and tooling using Node.js for testing, deployment, indexing, and integrations

• Test smart contracts using Node.js-based tooling such as sandbox, blueprint, and related frameworks

• Work with Jetton smart contracts and TON token mechanics

• Deploy smart contracts to testnet and mainnet

• Build and maintain services interacting with TON nodes, RPC / APIs, and indexing data pipelines

• Occasionally interact with EVM smart contracts (Solidity) for integrations and cross-ecosystem compatibility

• Improve reliability, performance, and security of distributed and blockchain-based systems

Requirements

• Strong production experience with Go

• Practical experience writing smart contracts in FunC

• Understanding of asynchronous blockchain execution models

• Experience with Jettons or other TON token standards

• Hands-on experience with Node.js for blockchain tooling, testing, deployment scripts, or backend services

• Solid understanding of blockchain fundamentals

• Ability to work independently in a remote, fast-moving environment

• Russian and English working proficiency

What we offer

• Competitive compensation

• Fully remote work

• Direct impact on a blockchain product integrated with the TON & Telegram ecosystem
