Informal is a core contributor to Cosmos, where we develop interoperable blockchain systems by heavily relying on formal verification tools and techniques (formal specification in TLA+, symbolic model checker Apalache, Model Based Testing Framework, etc).

The Cosmos technology stack, including Tendermint Core, the Cosmos-SDK, IBC, and the Cosmos Proof of Stake modules, is an industry leading toolkit, written in Go, for building, deploying, and running community owned decentralized networks. This technology is used today to secure many billions of dollars in cryptocurrency market capitalization.

However, many of these components were designed in 2016, back when the Cosmos vision of an “Internet of Sovereign, Interoperable Blockchains” was but a dream. Today, it is rapidly becoming a reality, and with it, a new set of requirements and tremendous learnings about the technology stack necessary for the next 5 years. We are building this stack in Rust, including many of the key components of the Cosmos ecosystem, but designed more natively for a multi-chain reality. This includes Hermes, the leading IBC relayer for communication between blockchains, as well as a new multi-chain consensus node based on Tendermint and a new framework for developing secure and verifiable applications in Rust.

What your primary responsibilities will be:

  • Design and develop our products and software.
  • Improve the user experience, correctness, code-quality, and performance of the software.
  • Contribute clean, well tested, and well documented code.
  • Review issues and pull requests and provide valuable feedback to contributors.
  • Mentor other engineers and support the growth and health of the team.
  • Guard the quality of the software from technical debt, missing tests or documentation, and feature creep.
  • Nurture a safe and enjoyable open source experience for contributors.

What we look for in a successful Rust Engineer:

  • At least 3 years developing, releasing, and maintaining production software.
  • Significant experience writing Rust or the ability and desire to become proficient in new languages.
  • Commitment to product quality, user experience, and well-structured code.
  • A track record of designing maintainable APIs that are a delight to use.
  • Experience with p2p networking, fault tolerant consensus protocols, blockchain application development, or other related technologies.
  • A deep understanding of computer science fundamentals.
  • The ability to take ownership and see initiatives through.
  • Excellent interpersonal skills, experience working with distributed teams, and enjoys working with and mentoring others.
