Senior Protocol Engineer

We’re looking for an incredible software engineer to help us build the future of blockchain scalability. This is an ideal opportunity for an engineer who is already passionate about tackling problems in blockchain scalability, or looking to break into the blockchain engineering space. If you’re looking to work in a fast-paced, high-impact team and help shape the direction of our product and company, this position is for you. We’re backed by some of the best investors in the valley and offer competitive pay, an equity grant in the company, and full benefits. About Caldera

Caldera enables dynamic, scalable blockchain experiences. Currently, dapps that are deployed to general-purpose blockchain compete with thousands of other applications for space on the network — this can lead to

congestion and high fees

or even

network outages . That’s where we come in.

We’re building software that makes it easy for the most innovative blockchain applications to launch their own ultra-performant blockchains ( rollups ), enabling applications to own their ecosystem, scale to millions of users, and provide a superior user experience to their players. We’re located in San Francisco, and work in-person from the Financial District As a Senior Protocol Engineer at Caldera, you will:

Help architect the blockchain node that comprises the backbone of our software offering. You’ll be working on the cutting edge of blockchain scaling, building new kinds of layer twos.

Make improvements or extensions to the virtual machine that runs Ethereum smart contract code ie custom precompiles

Evaluate database backends, networking libraries, and other tools and help make decisions as to which should be included in our stack

Write efficient and secure EVM smart contracts in solidity

You might be a fit for this role if you...

Have 4+ years of engineering experience

Have a deep knowledge of Go, Rust or similar languages

Have built Ethereum “dapps” with Solidity or Yul

Have experience working with distributed or embedded systems before

Love writing fast, well-optimized, well-tested, clean code

Are confident with performance optimization, identifying bottlenecks and scalability concerns

Bonus points if you...

Are familiar with how blockchains like Ethereum or Bitcoin work under the hood

Are up-to-date with Ethereum scaling solutions such as sidechains or rollups

Have implemented or used a consensus algorithm (eg. Paxos/Raft, pBFT, tendermint, ...) in the past

Have an understanding of cryptography primitives, such as hash functions or digital signatures

Have significant open-source contributions, especially in blockchain clients/node software, databases, networking, or programming languages/frameworks

If in doubt, please apply We will find a place for great candidates, even if you feel that you don’t check all of the boxes
