  • General purpose automatic MUD indexers with support for arbitrary SQL queries running in WASM
  • Libraries to encode/decode data with custom highly efficient encoding protocols
  • Development and deployment tooling for complex smart contract applications
  • Dashboards to inspect the internal state of complex smart contract applications

  • General purpose plugin systems with strong types

  • Passion for software development and improving developer experience
  • You’re in love with type magic and have written a lot of TypeScript
  • You are passionate about writing clean software and building - ideally side projects or even a company
  • You are passionate about building tools to improve developer experience


  • Competitive salary (144k-175k).

  • Premium private medical insurance in the UK, US, and other countries where available.
  • Flexible PTO with a high level of freedom and autonomy for your work. You receive a bonus if you take at least 25 days of PTO a year.
  • Paid travel - team on-sites in different parts of the world, several times a year.

About Lattice

Lattice is building tools and infrastructure across the entire crypto stack - from L2s to applications - to make autonomous worlds possible. Our goal is to transition Ethereum from a financial computer to its original ambition as the World Computer.

Our most major contribution so far is MUD. MUD is an onchain operating system for Ethereum. It is built as a micro-kernel, with its core module being an embedded relational database that replaces the traditional storage model of Ethereum. All of MUD is onchain and runs on the EVM. Countless onchain games use Lattice today, from our own projects like OPCraft and Sky Strife, to games like Primodium and Words3, to major venture-backed gaming companies currently in stealth, to the hundreds of teams using MUD in the recent ETHGlobal Autonomous Worlds hackathon.

We are a very small team of highly efficient engineers, have a low bureaucratic overhead and are focused on shipping code to production. We maintain short cycles that makes code we write reach a strong grass root community of developers almost immediately.

Our Team

Lattice is currently 13 people living across North America and Europe, with 5 based in our London office.
