Site Reliability Engineer

Cimulate is an AI-native eCommerce search and discovery platform built on cutting-edge LLM technology. We help commerce brands deliver radically better shopping experiences—faster, more relevant, and easier to manage—by understanding context rather than relying on brittle rules-based personalization. Backed by top investors and founded by a team who’ve already built and sold another commerce startup (Celect to Nike), we’re now building the future of contextual commerce, and we’re just getting started.  

The Role
Cimulate is seeking a skilled Site Reliability Engineer to join our dynamic team as we revolutionize the future of commerce through intelligent, AI-driven systems. In this pivotal role, you’ll own the reliability, availability, and performance of our SaaS production environment—monitoring critical systems, managing deployments, and ensuring seamless operations for our customers. As a Site Reliability Engineer, you’ll manage production support processes, deployments (including model releases), and incident response, with an opportunity to grow the role into managing vendor partners for 24/7 follow-the-sun coverage. This position combines hands-on technical problem-solving with process ownership and operational leadership.

Your work will directly contribute to the stability and scalability of Cimulate’s AI platform, supporting our mission to help businesses operate and engage more intelligently.

Responsibilities

• Ensure reliability, availability, and performance of SaaS production systems and AI pipelines.
• Monitor production environments, deployed models, and data pipelines; respond rapidly to incidents and service disruptions.
• Manage deployments, configuration changes, and release processes (e.g., model and service rollouts).
• Maintain and enhance observability, monitoring, and alerting systems (e.g., Grafana, Prometheus, ELK).
• Lead incident response, postmortems, and continuous improvement of operational processes and playbooks.
• Partner with DevOps and engineering teams to improve scalability, fault tolerance, and automation.
• Track and improve reliability metrics (SLAs, SLOs, SLIs).
• Create and maintain clear technical documentation, including runbooks and escalation paths.
• Participate in on-call rotation and drive improvements in incident management and response.
• Grow into managing vendor teams providing 24/7 L1 operational coverage.

Requirements

• Proven experience in monitoring and supporting production systems, preferably in a SaaS or multi-tenant environment.
• Strong knowledge of Linux systems and scripting (Python, Bash, or Go).
• Hands-on experience with cloud platforms (GCP preferred; AWS/Azure also valuable) and container orchestration (Kubernetes, Docker).
• Familiarity with Infrastructure-as-Code (IaC) tools such as Terraform or Pulumi.
• Understanding of networking, databases, and performance tuning.
• Experience with observability, monitoring, and logging tools (Grafana, Prometheus, ELK, etc.).
• Proficiency with Git, version control workflows, and CI/CD pipelines.
• Strong analytical, debugging, and problem-solving skills.
• Excellent communication and collaboration abilities, including with non-technical stakeholders.
• Calm under pressure and effective in incident management situations.
• Growth mindset with the ambition to build and lead scalable 24/7 production operations.

Nice to haves
