About Avik Chatterjee

I’m an Engineering Manager specializing in Site Reliability, Incident Response, and organizational transformation, with 19+ years of experience improving the stability and performance of large-scale distributed systems. I lead reliability programs across 10+ product lines, and a 1300+ engineer on-call organization, combining engineering discipline, operational excellence, and people leadership.A defining part of my career was transforming Cvent’s NOC from a reactive support team into an engineering-aligned function. I built the capability framework, upgraded competencies, and ultimately merged the NOC into the SRE organization, creating a unified reliability team with stronger technical depth, better signal quality, and higher execution standards.I focus on engineering resilience into systems using SLO-driven practices, modern observability, DR readiness (AWS FIS), fault isolation, and resiliency patterns such as timeouts, retry budgets, circuit breakers, and bulkheads. I also leverage AI-assisted operations for past incident correlation, major incident summary, status site updates, and RCA acceleration.People leadership is core to my approach. I’ve managed SRE and NOC teams, led performance and career development, and partnered with L&D to design structured training, onboarding, and capability uplift programs—helping 40+ engineers grow stronger in production ownership, troubleshooting, and decision-making.

Experience

1. Site Reliability Engineering Manager

   Cvent

   Jan 2019 — Present · Gurgaon, IN

   As Engineering Manager for Reliability Programs, I lead reliability strategy across 100+ microservices, 10+ product lines, and a 1300+ engineer on-call organization. My role focuses on strengthening system resilience, improving incident response, maturing observability, and scaling operational excellence across engineering teams.I developed and executed Cvent’s 2024–2025 Reliability Roadmap, driving improvements in incident response, detection maturity, SLO/SLA governance, and DR readiness. Through workflow redesign, enriched telemetry, and resolver engagement improvements, I helped reduce MTTR by ~45% YoY.I rebuilt the Major Incident Management Program, integrating Production + Security workflows and training 30+ Incident Commanders and 700+ First Responders. I improved on-call operations by standardizing PagerDuty usage for 1300+ engineers, reducing TTE from 30 mins → 10.5 mins, cutting misconfigurations by 40%, and achieving 35% cost savings.I introduced AI-assisted operations, including AI-based recurrence detection of major incidents, AI-generated incident summaries, and RCA drafting. These changes accelerated detection, improved triage, and reduced noise.I led Cvent’s DR Readiness Program using AWS FIS AZ-failure simulations, improving audit readiness and failover confidence by ~70%. I also standardized DR playbooks and reporting across product lines.Additionally, I modernized SLA calculations for multiple platforms, improving accuracy by >90% and preventing ~$250K annual revenue leakage. I partner closely with engineering, architecture, product, and security to embed resilience patterns (timeouts, retries, circuit breakers, bulkheads) and ensure operational readiness for all services.
