Frequently Asked Questions

What are blockchain infrastructure companies?

▾

Blockchain infrastructure companies build the foundational layers that the rest of the Web3 ecosystem runs on. This includes Layer-1 networks (Ethereum, Solana, Avalanche, Polkadot), Layer-2 scaling solutions (Polygon, Optimism, Arbitrum, zkSync), smart contract platforms, developer tooling companies (Hardhat, Foundry, Tenderly), RPC and node providers (Alchemy, Infura, QuickNode), and cross-chain interoperability protocols (Chainlink, Wormhole, LayerZero). These companies hire the deepest blockchain engineers in the industry.

What roles do blockchain infrastructure companies hire for?

▾

Core protocol engineering roles are the most common, requiring deep experience in systems programming languages like Rust, C++, or Go. Smart contract engineers proficient in Solidity, Vyper, or Ink! are in constant demand for building on-chain primitives. Cryptography researchers working on zero-knowledge proofs, consensus mechanisms, and cryptographic protocol design are among the highest-paid specialists. Infrastructure companies also hire distributed systems engineers, DevOps engineers with blockchain node experience, developer relations engineers, and technical writers for protocol documentation.

How much do blockchain infrastructure engineers earn?

▾

Blockchain infrastructure engineers command some of the highest salaries in the entire tech sector. Senior protocol engineers at well-funded Layer-1 and Layer-2 networks typically earn $150,000–$350,000 in base salary, with substantial token grants on top. Cryptography researchers and zero-knowledge proof specialists can exceed $400,000 in total compensation at leading protocols. Smart contract engineers at infrastructure companies earn $120,000–$250,000, while DevOps engineers specialising in blockchain node management earn $100,000–$200,000. These numbers reflect the extreme scarcity of talent with the required skills.

Do blockchain infrastructure companies hire remotely?

▾

Yes — nearly all Layer-1 and Layer-2 protocols operate as fully distributed teams. The open-source and decentralised nature of blockchain infrastructure means contributors are spread across every timezone, and most organisations are built around async-first workflows. Whether you are a Rust engineer in Eastern Europe, a cryptographer in Asia, or a DevOps specialist in South America, the majority of infrastructure roles on Cryptogrind are open to candidates anywhere in the world.

What skills do I need to work at a blockchain infrastructure company?

▾

For core protocol roles, systems programming proficiency in Rust, C++, or Go is essential, along with a deep understanding of distributed systems, consensus algorithms, and peer-to-peer networking. Smart contract engineers need mastery of Solidity or Rust (for Solana and Substrate-based chains), gas optimisation techniques, and formal verification methods. Cryptography roles require graduate-level knowledge of elliptic curve cryptography, zero-knowledge proof systems (SNARKs, STARKs), and homomorphic encryption. Contributing to open-source blockchain projects is the single most effective way to build the portfolio that infrastructure hiring teams look for.

How do I get a job at a blockchain infrastructure company on Cryptogrind?
