Staff Backend Engineer

We’re looking for an incredible staff 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 users. We’re located in San Francisco, and work in-person from the Financial District As a Staff Backend Engineer at Caldera, you will:

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

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

Have 4+ years of engineering experience

Have experience writing backend services in Go or Typescript

Have experience designing, building, and maintaining robust APIs

Have a strong ability to design efficient and scalable data models.

Strong background with cloud computing platforms, especially AWS

Keen eye for security, solid understanding of threat modeling and secure system architecture

Bonus points if you...

Have experience with modern infrastructure; containerization, infrastructure as code, kubernetes

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

Have built Ethereum “dapps” before

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
