Company mission
To empower developers to build apps in Web3 by making it easy for anyone to launch performant, customizable layer-two blockchains.
Role
Who you are
- Have 5+ years of engineering experience, including at least 2 years of experience developing high-availability, distributed systems
- Have a deep knowledge of Go, Rust or similar languages
- Have built complex Ethereum “dapps” with Solidity or Yul
- Are comfortable building systems that secure user’s funds
- Love writing fast, well-optimized, well-tested, clean code
- Are confident with performance optimization, identifying bottlenecks and scalability concerns
Desirable
- Have implemented MEV/intents solvers
- Have implemented or used a consensus algorithm (eg. Paxos/Raft, pBFT, tendermint, ...) in the past
- Understand tradeoffs in the blockchain interop space and how advancements like ZK, preconfirmations, fast finality impact design considerations and differ
- Have significant open-source contributions, especially in blockchain clients/node software, databases, networking, or programming languages/frameworks
What the job involves
- We’re looking for an incredible senior 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
- Architect and develop backend systems to ensure the smooth operation of Caldera’s blockchains
- Build secure and scalable crypto-native systems on EVM blockchains ie indexers or relayers
- Take ownership of new features from conception through to deployment for Caldera’s self-serve infrastructure platform
- Take the lead on data model design, ensuring that databases are optimized for performance, scalability, and reliability
- Engage in performance tuning and optimization efforts, profiling systems then reducing latency + increasing throughput
- Be a source of technical leadership and mentorship; for example, providing high-quality feedback and code reviews for junior engineers
Our take
As the interest in blockchain technology rises, the growth in network usage and on-chain apps can cause network congestion or even outages, lowering performance for users. Caldera (formerly Constellation Labs) makes it easy to launch performant, customizable blockchain rollups and is developing the world's rollup-as-a-service platform.
Just as the internet is run on millions of servers worldwide, Web3 will outgrow its current set of blockchains. This means thousands of projects will opt to launch their dedicated blockchains so they can own their ecosystem, scale without limit, and provide superior user experiences. Caldera enables developers to “roll up” their transactions into a single piece of data to be submitted to the main net, then, those transactions are removed from the main net, creating space and increasing processing speeds.
Caldera has completed a significant funding round, marking a significant milestone for the company. With this new capital, its expanding its team and further developing its Metalayer initiative for a promising future in the rapidly growing blockchain space.
