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 Senior 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, i.e., 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 and 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.
