We’re looking for an incredible software engineer to help us build the future of blockchain scalability. You will work on the systems that deploy and upgrade our core supported rollup frameworks - Arbitrum, OP Stack, and ZKsync – as well as make them work with emerging technologies from shared sequencers to alternative DA layers.
This is the ideal opportunity for an engineer with existing experience working on rollup node software of someone familiar with offchain services which secure significant value.
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 and equity, and full benefits.
About CalderaCaldera 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 New York, and work in-person or remotely.
As a Senior Protocol Engineer at Caldera, you will:
Help architect the blockchain nodes that comprises the backbone of our software offering. You’ll be working on the cutting edge of blockchain scaling, building new kinds of L2s.
Develop improvements to rollup stacks like OP, zksync, and Arbitrum Orbit, making them higher throughput and more reliable.
Create systems that ensure zero-downtime network upgrades of high TPS chains caldera has in production, which secure hundreds of millions of dollars in value.
Write efficient and secure EVM smart contracts in solidity
Drive the technical direction, establish roadmaps, communicate and collaborate with internal and external partners to help Caldera win.
Have 4+ years of engineering experience, including at least 1 year of experience working with EVM-related protocols (dApps, Rollups, Solvers, etc).
Have a deep knowledge of Go, Rust or similar languages
Have built Ethereum “dapps” with Solidity or Yul
Have experience developing and deploying distributed systems.
Love writing fast, well-optimized, well-tested, clean code
Are great at solving complex design, latency, or performance problems in high-throughput production systems.
Are confident with performance optimization, identifying bottlenecks and scalability concerns
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

What We Do
It all started with a challenge. We were enthralled by blockchain technology and its potential to change everything on the internet, but saw that it was hampered by terrible performance. We recognized pretty early on that just attempting to make a single faster blockchain wasn’t the best solution. To truly reach web-scale on Ethereum, we would need to scale horizontally.
In 2022, we launched Caldera. With our platform, projects can deploy a rollup with a single click, without an engineering team. We take care of deployment, customization, ongoing maintenance, and security, so projects can focus on building their vision.
Today, Caldera is one of the fastest growing rollup ecosystems on Ethereum. We’ve empowered web3 teams to customize and launch over 60 high-performance rollups across a number of app categories, and projects have free reign to launch their rollup on Optimism, Arbitrum, ZKsync, and Polygon stacks.
At present, the Caldera ecosystem comprises 1.7 million unique wallets holding over $800 million in TVL, with more than 60 million completed transactions. Some notable chains in our ecosystem include Manta Pacific, inEVM by Injective, ApeChain, Treasure, Plume Network, Towns, Kinto, RARI Chain, and Zero Network by Zerion.
