Site Reliability Engineer (SRE)

The cloud is broken: It's wasteful, slow, awfully expensive, and burdened with legacy tech that wasn't built for today's workloads. At Unikraft we're building a generational, truly millisecond-native, extremely scalable cloud platform that provides exponentially higher efficiency. Are you bored with your current job? Want to push the boundaries of what's possible in the cloud to the absolute limit?

Our team consists of some of the best systems, performance, and security geeks out there, and is backed by top investors with category leaders as our customers. We believe a focused team of exceptional people, moving fast with conviction, can rebuild the cloud from first principles and make extreme efficiency (eg, millions of users on a few servers) available to everyone.

What You’ll Do

- Maintain and operate customer on-prem and cloud deployments of our platform, ensuring reliability and rapid troubleshooting of technical issues.

- Plan, package, and roll out software updates both internally and to customers, including testing and validation.

- Collaborate with engineering to ensure quality deployments and maintain a high standard of product reliability.

- Set up and manage monitoring systems to proactively detect and resolve issues in production environments.

- Write scripts and automation for deployment, infrastructure management, and CI/CD workflows.

- Deploy, manage, and troubleshoot Kubernetes clusters for reliable, scalable infrastructure.

- Build tooling and automation to streamline deployment and platform integration.

- Contribute to continuous integration pipelines that catch regressions across components and system integrations.

- Create and maintain clear documentation for systems, processes, and tools to support team effectiveness.

What We’re Looking For

- At least 2 years of experience working in high-pressure environments.

- Proven experience in Linux system administration, software packaging, and delivery.

- Solid understanding of Linux networking fundamentals, including firewalls, DNS, proxies, and best practices.

- Experience managing and troubleshooting Kubernetes clusters in production.

- Good understanding of the CNCF/cloud-native landscape and associated tools.

- Familiarity with observability tools such as Prometheus and Grafana.

- Basic scripting skills (e.g., Bash, Python).

- Familiarity with cloud platforms (e.g., AWS, GCP, Azure).

- Interest in automation tools like Ansible, Terraform, or similar.

- Exposure to CI/CD pipelines (e.g., GitHub Actions, Jenkins, GitLab CI).

- Familiarity with microservice architectures, Serverless, and DevOps best practices.

- Familiarity with virtualization solutions like QEMU/KVM. Micro-VMMs like Cloud-Hypervisor or Firecracker are a plus.

Mindset

- Eagerness to learn and take on new challenges.

- Strong problem-solving skills and a curious, analytical mindset.

- Enthusiasm for building reliable, high-performance systems.

- Team player with good communication skills.

- Ability to quickly adapt to new programming languages, runtimes, and environments.

Why This Role is Career-Defining

- Help revolutionize the future of cloud compute runtime while embracing continuously evolving modern technologies.

- Work alongside a high-energy, top-notch, technical, and entrepreneurial team.

- Make impactful contributions and help shape our rapidly growing company.

- Gain deep hands-on experience with infrastructure and modern DevOps practices while learning from experienced engineers.
