About The Role

We are seeking a Senior Site Reliability Engineer (Senior SRE) to drive the scalability, reliability, and efficiency of our critical systems and infrastructure. As a senior member of the team, you will lead SRE initiatives, mentor engineers, and architect solutions that enhance system resilience and operational excellence. You will work closely with engineering, DevOps, and security teams to implement automation, observability, and reliability best practices across the organization.

Reliability Engineering

• Define and drive SRE best practices, including SLOs, SLAs and resilience engineering.
• Lead incident management and post‑mortem analysis, ensuring continuous improvement in system reliability.
• Establish disaster recovery (DR) and high‑availability (HA) strategies to meet business continuity goals.
• Develop and optimize incident response playbooks, reducing mean time to resolution (MTTR).

Observability, Monitoring, and Performance Engineering

• Define and implement advanced monitoring, logging, and tracing strategies using tools like Prometheus, Grafana, Datadog, or New Relic.
• Perform capacity planning, load testing, and performance tuning to optimize system health.
• Introduce AIOps and machine learning‑based anomaly detection for proactive issue resolution.

Security, Compliance, and DevSecOps

• Implement security best practices, including infrastructure hardening, zero‑trust principles, and identity management.
• Ensure compliance with SOC2 and ISO 27001.

Mentorship & Cross‑Functional Collaboration

• Mentor and coach junior SREs, fostering a culture of reliability.
• Work closely with development teams to ensure reliability is built into the software lifecycle.
• Advocate for chaos engineering, game days, and resilience testing to enhance system robustness.

Qualifications

• Bachelor's or Master's degree in Computer Science or a related field.
• 5+ years of experience in Site Reliability Engineering, DevOps, or Infrastructure Engineering.
• Strong experience with cloud platforms (AWS, GCP, or Azure) and cloud‑native technologies.
• Expertise in Kubernetes and container orchestration.
• Expertise with log management tools like ELK or Graylog.
• Strong coding/scripting skills in Python, Go, or Bash for automation.
• Deep understanding of networking, DNS, CDN, load balancing, and security.
• Proven experience with observability tools (Prometheus, Grafana, ELK, OpenTelemetry).
• Hands‑on experience in performance tuning, high availability, and DR strategies.
• Strong knowledge of incident management frameworks and reliability metrics (SLOs, SLIs, SLAs).
• Experience leading cross‑functional reliability initiatives.

Preferred Qualifications

• Experience in a fast‑paced, agile development environment.
• SRE Certifications from Datadog/Google.
• Experience with Chaos Engineering.
• Exposure to AIOps and ML‑based observability.
• Experience in leading SRE transformations at scale.
• Experience in multi‑timezone support.
• Experience working for B2B products from scratch would be a big plus.
