About TAC TAC is a Layer 1 blockchain with a native adapter for TON, enabling Ethereum-based applications to access Telegram’s user base of over 1 billion people.

Our mission is to scale the TON developer ecosystem by onboarding Solidity/EVM engineers and helping launch hundreds of new dApps for TON users—especially in consumer-facing use cases via Telegram MiniApps.

We’re in a fast growth phase: post-fundraising, with a strong team of crypto natives and former corporate leaders. We're now building a new independent chain based on the Cosmos SDK.

The Role

We’re looking for an experienced Cosmos SDK Developer to help us design and build a new standalone blockchain network based on the modular Cosmos architecture.

Our goal is to develop a liquid staking network with IBC support and cross-chain interoperability.

Responsibilities

  • Develop and maintain Cosmos SDK modules in Go

  • Configure and launch a full blockchain application (genesis, nodes, consensus)

  • Implement cross-chain functionality via IBC and Interchain Accounts

  • Build systems for rewards, delegation, and custom distribution logic

  • Integrate with external services (relayers, monitoring, governance tooling)

  • Maintain CI/CD pipelines and test infrastructure for the node

  • Contribute to architecture discussions and perform code reviews

Requirements

  • Strong proficiency in Go

  • Experience developing and modifying Cosmos SDK modules

  • Solid understanding of Cosmos SDK architecture (app.go, keepers, multistore, messages), Tendermint (CometBFT), and IBC

  • Hands-on experience launching and configuring custom networks (ideally with IBC)

  • Familiarity with Interchain Accounts

  • Understanding of the Cosmos ecosystem and DeFi concepts

  • Experience deploying and testing smart contracts (a plus)

What We Offer

  • Competitive and fair compensation, aligned with your experience and responsibilities

  • Influence the architecture of a new blockchain from the ground up

  • Access to key growth opportunities within the TON ecosystem

  • Flexible schedule (CET-friendly hours preferred)

Why Now

TAC is preparing for Mainnet launch. We’ve already passed $200M+ in TVL, established major partnerships, and secured infrastructure integrations. With strong support from TON’s core ecosystem players, now is the perfect time to join and leave your mark on a new chain’s evolution.
