Site Reliability Engineer

About Runloop

Runloop is building the foundational infrastructure for the next generation of AI development. We provide AI engineers and data scientists with lightning-fast, secure, and reproducible code sandboxes. Our platform enables teams to experiment, iterate, and deploy their projects without the friction of environment setup and dependencies. We are a small but mighty team dedicated to building a rock-solid platform that empowers innovation.

The Role

We’re looking for a skilled and passionate Site Reliability Engineer to join our team. As an SRE, you’ll be responsible for the reliability, observability, performance, and security of our core platform—the very foundation on which our users build their futures. You’ll work closely with our engineering team to develop and maintain the systems that power our code sandboxes, ensuring a seamless and stable experience for our customers. This is a critical role that blends a deep understanding of operations with a software engineering mindset.

Responsibilities

Design and maintain our production infrastructure on cloud platforms like AWS, GCP, or Azure.

Monitor and respond to system alerts and incidents, ensuring high availability and a secure environment for our users’ code using Grafana and Prometheus.

Collaborate with developers to ensure new features and services are designed with scalability and reliability in mind.

Troubleshoot and resolve complex issues related to our infrastructure, networking, and the sandbox environment.

Participate in an on‑call rotation to support our production systems.

Define and track SLIs / SLOs, manage error budgets, and proactively monitor distributed systems with logging and tracing.

Automate deployments, scaling, provisioning, and recovery tasks to reduce toil and build self‑healing systems.

Lead incident response, conduct root‑cause analysis, and facilitate blameless post‑mortems to drive continual improvement.

Collaborate cross‑functionally with product, engineering, and developer relations to ensure reliable releases and an outstanding developer experience.

Plan for capacity growth, forecast system usage, and contribute to safe release and change management processes.

Mentor and support front‑end developers in building reliable distributed front‑end systems (CDNs, caching, client‑side observability).

Qualifications

Proven experience as an SRE, DevOps Engineer, or similar role.

Strong programming skills in languages like Python or Go.

Deep expertise in containerization technologies such as Docker and Kubernetes.

Experience with cloud infrastructure and tools like Terraform and / or Pulumi.

Familiarity with monitoring and alerting tools like Prometheus, Grafana, or Datadog.

A solid understanding of networking, security, and Linux systems administration.

Experience designing, scaling, and maintaining distributed systems (backend platforms, APIs, or front‑end infrastructure).

Proficiency in implementing observability frameworks (metrics, logging, tracing) and aligning reliability goals with developer velocity. Hands‑on experience managing incidents, running on‑call operations, and producing actionable post‑mortems.

Ability to mentor engineers and influence reliability practices across teams, especially for front‑end infrastructure and performance.

Bonus Points

Experience with chaos engineering techniques, front‑end observability tools (e.g., Sentry, RUM, synthetic monitoring), or building CI / CD pipelines for front‑end delivery.

Benefits

Competitive salary and equity.

Comprehensive health, dental, and vision insurance for you and your dependents.

Opportunity to work on cutting‑edge AI technology and make a real impact on the future of software engineering.

Free lunch and snacks.

Location

In office 4 days a week in San Francisco, optional 1 day a week WFH.
