The Hardhat, the most widely used Ethereum development environment. We’re dedicated to building open-source infrastructure and tools that empower Ethereum developers to decentralize the world while fostering growth and innovation in the developer ecosystem.

We are looking for a Senior Engineer with extensive experience working with systems software to join our team responsible for Slang, our compiler project.

Slang is a modular set of compiler APIs empowering the next generation of Solidity code analysis and developer tooling. Written in Rust and distributed in multiple languages. We just released a version-stable parser, and we are looking into semantic analysis and error recovery next. We are a small team (3 people currently), but we have ambitious plans about Slang and the future of Solidity developer experience.

This is a fully-remote role, and we’re open to candidates applying within UTC+1 to UTC-4 timezones.

In this role, you will be:

• Designing and implementing features in the compiler, language specification, and testing infrastructure.
• Writing up user facing documentation and tutorials on how to use Slang.
• Providing code reviews and assistance to other engineers on the team.
• Investigating bug reports and responding to user feedback on GitHub and Telegram.

Tech stack:

• Rust
• Node.js / N-API
• Ethereum / EVM

The skills we look for:

• At least 5 years of experience working on low-level systems software
• 2+ years of working with Rust
• Knowledge and experience with Node.js
• We work remotely and mostly asynchronously, so the ability to take ownership and work with minimal direction is crucial
• As this is an early-stage project, we are seeking a teammate who is comfortable adapting to changing requirements
• Prior experience working in a remote and globally-distributed environment
• Experience in leading projects & mentoring other team members

Why is this an exciting opportunity?

• You’ll have a chance to work on a core component of the Ethereum stack and support the entire Ethereum ecosystem to be more productive
• Contribute to Ethereum as a project
• Service the needs of high-profile projects that use Hardhat
• All of your work will be open-source, and you’ll have the chance to collaborate with other open-source projects (both inside and outside Ethereum)
