3Box Labs

Do you want to build the foundations of a better web alongside a passionate, high-impact team? 3Box Labs is building the data rails for Web3, Ceramic Network. Already used by 1500 of the world's most ambitious applications, Ceramic is the building block for composable data.

You'll tackle some of the most novel challenges in decentralized tech, work closely with our rapidly growing open source community and many of the best technologists in the world, and help reinvent how data is managed online.

The Role

As our first Blockchain Engineer you will lead engineering, implementation and optimization of the Ceramic Blockchain and contribute to the overall cryptoeconomic design of the network.

You will..

  • Evaluate and implement cutting edge cryptographic data structures, such as HAMTs, Verkle trees, and Merkle tree variations
  • Create a solid architecture for the software implementation of the Ceramic blockchain, making proper tradeoffs between scalability, feasibility, and complexity
  • Evaluate and implement cutting edge cryptographic primitives such as BLS signatures and ZKPs
  • Draw on existing blockchain frameworks, modules, and implementations such as Substrate, Cosmos, Filecoin, and Ethereum
  • Optimize low level networking to suite our needs (libp2p)
  • Keep up to date with developments and research in the broader blockchain ecosystem
  • Collaborate closely with the Ceramic core protocol team
  • Produce accessible documentation that make it easy for new developers to dive into the Ceramic code base

You are likely a great candidate if you have..

  • Experience implementing an L1 blockchain
  • A deep drive to build resilient software systems
  • Knowledge of p2p database systems
  • Excellent communication and coordination skills
  • Attention to detail during design and execution - you don't let small tasks slip

The Team

We are a lean, voraciously curious team from across the globe. We have 4 years of expert remote work experience and frequent (and awesome) team retreats to spend time together. We are impact-driven, intentional about our role, communications and actions, and intensely focused on building quality tools for our open source community. We believe a better model for managing identity and data online can give power back to users and builders, that this model is key to a growing movement, and that our team is a critical part of making that movement successful.

We pay competitively and fairly across the globe, offer great and flexible benefits, and view everyone on our team as an owner -- both with generous equity grants and lots of agency to help set our direction.

We are committed to building a diverse and inclusive team. We cannot succeed in our mission without it. People that identify with groups traditionally underrepresented in tech are particularly encouraged to apply.
