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
