# Site Reliability Engineer

**Company:** [Cognition](https://hotfix.jobs/companies/cognition)
**Location:** San Francisco, CA
**Role:** DevOps / SRE
**Skills:** Kubernetes, Terraform, AWS, GCP, Azure, CI/CD, SLOs, Slis, Observability, Incident Response
**Posted:** 2025-10-13

> Owns production reliability (SLOs, monitoring, incident response) and platform engineering (CI/CD, infrastructure as code) for AI developer tools used by hundreds of thousands. Requires deep production systems experience, strong coding skills, and cloud proficiency.

## Job Description

## What You'll Accomplish

### Production Reliability
- Define and own SLOs, SLIs, and error budgets for Devin and Windsurf.
- Build the monitoring, alerting, and observability systems that give the team a clear, honest picture of service health at all times.

### Incident Response and On-Call
- Lead incident response with speed and clarity.
- Run blameless postmortems that turn outages into durable improvements.
- Build the runbooks and tooling that make on-call sustainable and effective.

### Platform Engineering and CI/CD
- Own the deployment pipelines, release infrastructure, and internal developer tooling that let the team ship fast without breaking things.
- Reduce toil systematically so engineers spend time on work that matters.

### Infrastructure as Code
- Manage cloud infrastructure through code.
- Build reproducible, auditable, version-controlled environments that scale with the product and eliminate configuration drift.

### Capacity Planning and Performance
- Model growth, forecast resource needs, and ensure the infrastructure stays ahead of demand.
- Profile and improve system performance before users feel it.

### Security and Reliability as One
- Treat security not as a separate concern but as a reliability requirement.
- Ensure that misconfigurations, vulnerabilities, and access failures are caught and remediated with the same urgency as outages.

### Reliability Culture
- Partner closely with product and engineering teams to build reliability in from the start.
- Be the person who catches the single point of failure in the architecture review before it becomes a page at 2am.

## Exceptional Candidates Have Demonstrated
- Deep experience running production systems at scale: SLOs, error budgets, on-call rotations, and incident command
- Strong software engineering fundamentals; SRE at Cognition means writing real code, not just configuring tools
- Proficiency with cloud infrastructure (**AWS**, **GCP**, or **Azure**), container orchestration (**Kubernetes**), and infrastructure as code (**Terraform** or equivalent)
- Experience building and owning CI/CD pipelines and deployment infrastructure for fast-moving product teams
- Strong observability instincts: knows how to instrument systems, build useful dashboards, and design alerts that surface signal without generating noise
- A track record of reducing toil systematically through automation, not just working around it
- Comfort owning incidents end to end: detection, triage, mitigation, resolution, and postmortem
- Enough product empathy to understand what reliability means from a user's perspective, not just an infrastructure one
- Experience with developer-facing products or platforms is a strong plus
