What You’ll Do

• Improve smart contract performance with a strong focus on reducing gas consumption, validating each optimization through measurable benchmarks.

• Build and support precompiles within the blockchain execution client.

• Rework and improve existing Solidity code to enhance efficiency, maintainability, modularity, and upgradeability without changing expected behavior.

• Partner closely with the core protocol team to identify performance constraints across smart contracts, the EVM execution layer, and node infrastructure.

• Design and run load tests, profiling, and performance experiments to deliver tangible improvements in TPS, execution efficiency, and latency.

• Maintain a high engineering and security standard through comprehensive testing, code reviews, and collaboration with external security auditors.

What We’re Looking For

Required

• 3+ years of professional experience in smart contract development and/or blockchain protocol engineering.

• Strong hands-on Solidity experience, particularly with gas optimization and EVM internals.

• Proficiency in at least one systems-level language: Rust, Go, or C++, with the ability to work on precompiles and execution-client code.

• Practical experience with profiling, benchmarking, and performance testing, using tools such as Foundry, Hardhat, or equivalent.

• Strong understanding of the factors that influence blockchain performance, including block time, gas limits, execution costs, and state growth.

Bonus Points

• Experience contributing to EVM clients such as Reth, Geth, or Erigon, or to other L1/L2 protocol implementations.

• Experience engineering performance-sensitive on-chain applications, such as DEXs, perpetual trading protocols, or order-book systems.

• Familiarity with parallel execution, rollup architectures, or zero-knowledge technologies.

Language

• Good English and Vietnamese, both written and spoken.

Why This Opportunity

• Competitive compensation + token allocation — join early and have meaningful upside.

• Work with strong blockchain engineers on infrastructure focused on pushing Ethereum scalability forward.

• Fully remote — work from anywhere in the world.

• High-impact engineering — your work will directly influence protocol performance and the developer ecosystem built around it.

• Learning & growth — work on challenging problems across smart contracts, EVM execution, and blockchain infrastructure.
