Find Your Dream Job

We’re looking for a Site Reliability Engineer (SRE) who thrives in both application-level problem-solving and infrastructure design.

• Work in a DevOps environment, supporting ODC products running on Google Cloud Platform (GCP), with a focus on applying SRE principles for reliability and automation.
• Take ownership of both applications and infrastructure, ensuring the availability, performance, and scalability of our cloud-based services.
• Develop and maintain Infrastructure-as-Code (IaC) and automation pipelines using tools like Terraform, Helm, and GitLab CI/CD.
• Collaborate with development teams to enhance product reliability using a “you build it, you run it” mindset.
• Act as a key technical voice during Change Advisory Board (CAB) reviews for high-impact changes, providing Tier II expertise.
• Manage real-time system monitoring and drive continuous improvements in observability and alerting.
• Support the end-to-end deployment of ODC applications in the cloud — from design and configuration to rollout and performance tuning.
• Perform operational readiness reviews and shape product roadmaps with a focus on stability and scalability.
• Guide technical documentation, incident response processes, and SLA compliance across tiers.
• Participate in on-call support rotations (24/7) to ensure production systems remain resilient.

What You Bring:

• A degree in Computer Science or a related technical field.
• 4+ years of experience with application deployment, system operations, and cloud infrastructure.

Proficiency with:

• GCP services and Kubernetes in production environments
• Automation tools like GitLab, Terraform, Helm
• Linux systems, networking, and HTTP(S)/TCP/IP protocols
• Scripting languages like Shell or Python
• Experience with Agile methodologies and a DevOps/SRE mindset.
• A strong understanding of CI/CD pipelines, system integration, and monitoring tools.
• Ability to translate business requirements into scalable technical solutions.
