San Francisco, United States Caldera Full time
Senior Infrastructure Engineer, Security

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. 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 Senior Infrastructure Engineer, Security at Caldera, you will:
  • Own significant components of Caldera's core infrastructure
  • Architect and develop backend systems to ensure the smooth operation of Caldera chains
  • Improve our DevOps pipeline, which allows Caldera chains to be deployed reliably and securely
  • Increase the reliability of our infrastructure by continuously improving the observability stack
  • Maintain and enhance the security posture of our cloud infrastructure
    • AWS Security:
      • Develop, deploy, and maintain security measures within AWS environments to safeguard against various security threats.
      • Monitor, assess, and react to security incidents and vulnerabilities within AWS.
      • Adopt and enforce AWS security best practices, including IAM policy management, VPC setups, and network protection.
      • Conduct security evaluations and audits on AWS infrastructure, providing recommendations for enhancements.
    • Kubernetes Security:
      • Enhance and protect Kubernetes clusters to mitigate vulnerabilities and attacks.
      • Implement network policies, Role-Based Access Control (RBAC), and security contexts to solidify security measures in Kubernetes.
      • Monitor and address security incidents within Kubernetes clusters.
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 with cloud technologies, especially Kubernetes, Docker, Terraform, Helm
  • Hands-on experience with cloud / infrastructure providers, including AWS, Vercel, and Cloudflare
  • Keen eye for security, solid understanding of threat modeling and secure system architecture
  • Are confident with performance optimization, identifying bottlenecks and scalability concerns
  • Have familiarity with observability tools like Grafana or Datadog
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 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
