Job Description

Position Overview

The Site Reliability Engineer (SRE) ensures the reliability, scalability, and performance of complex distributed systems deployed across private, public, and hybrid cloud environments. This is a hands-on technical leadership role that combines deep infrastructure knowledge with software engineering expertise to build systems that are automated, observable, and operationally sustainable.

As a Site Reliability Engineer, you will play a central role in evolving the reliability and sustainability of the company’s core platform. Your work will directly shape the resilience of mission-critical systems deployed at customer premises, influencing not only internal engineering excellence but also the long-term trust and satisfaction of enterprise clients.

The successful candidate will work within a DevIntegration team, integrating multiple layers of the product stack to enable automated, Kubernetes-based GPU workload provisioning using the Cluster API framework. You will contribute both strategically and tactically - shaping architectural direction while also leading by example in implementation, troubleshooting, and mentorship.

Key Responsibilities

  • Reliability and Infrastructure Engineering
  • Design, deploy, and maintain highly available, fault-tolerant systems running on Kubernetes and bare metal infrastructure.
  • Define and manage Service Level Indicators (SLIs), Service Level Objectives (SLOs), and Error Budgets to balance innovation velocity with operational stability.
  • Lead system reliability initiatives, ensuring that uptime and performance targets are consistently achieved.
  • System Integration and Automation
  • Work within the DevIntegration team to integrate diverse components of the product stack, enabling end-to-end cluster provisioning and management.
  • Build automation pipelines using Infrastructure as Code (IaC) and CI/CD frameworks to ensure consistent, repeatable deployments.
  • Develop scripts, frameworks, and tools to eliminate manual interventions and improve system resilience.
  • Architecture and Design Leadership
  • Participate in and lead architectural discussions- from high-level design to low-level implementation - to ensure alignment with reliability, security, and scalability goals.
  • Collaborate with development and product teams to address functional gaps and propose sustainable technical solutions in a fast-paced environment.
  • Operational Excellence
  • Ensure long-term operational sustainability of the deployed product, including updates, incident management, and integration with third-party enterprise systems such as PKI, IAM, and SIEM.
  • Conduct performance optimization, capacity planning, and root cause analysis to maintain system health.
  • Champion automation of day-2 operations, such as monitoring, scaling, patching, and recovery.
  • Leadership and Mentorship
  • Take ownership beyond engineering scope when needed - leading planning, coordination, and execution activities with an end-to-end accountability mindset.
  • Mentor and support team members, sharing deep expertise in reliability engineering, infrastructure design, and troubleshooting best practices.
  • Actively contribute to defining and refining SRE standards and processes across the organization.
