Sumit Kaul is an experienced infrastructure and DevOps leader with over 16 years of engineering and architecture experience building secure, highly available cloud platforms at scale. Currently serving as a Staff Software Engineer at PayJoy in San Francisco, he specialises in creating CI/CD pipelines, implementing GitOps patterns, and modernising delivery processes across AWS, Kubernetes, and Terraform/Pulumi environments.
Throughout his career, Sumit has driven technical transformations across diverse industries, including fintech, retail, logistics, and the federal government. At PayJoy, he pioneered a zero-code observability platform using Open Telemetry that processes over 10 million daily hits across approximately 300 endpoints. His work has enabled teams to eliminate high-cost ORM patterns and optimize query performance using flame graphs and distributed tracing. He developed standard dashboards and runbooks that created a shared incident language across teams, cutting time-to-isolate issues by roughly 30-40% and improving overall reliability.
Prior to PayJoy, Sumit served as Enterprise/Solutions Architect at Grocery Outlet, where he translated enterprise architecture principles into concrete defaults and templates. He delivered multi-account landing zones with promotion rules, rollback contracts, and observability frameworks. His CI/CD modernisation efforts reduced lead time and change-failure rate by approximately 30%. At Crowley, he led a multi-year program to standardise the cloud foundation and build a shipping-data platform, developing hardened AWS reference architectures with reusable IaC modules and unified observability. Earlier roles at Anaplan, Coupang, and Capital One focused on building event-driven CI/CD systems, progressive delivery strategies, and serverless platforms that scaled across multiple clouds and business units.
Sumit holds multiple AWS certifications, including Solutions Architect, SysOps Administrator, Developer, and Cloud Practitioner. He earned his Master of Science in Computer Science from Indiana University, Bloomington, and his Bachelor's degree in Electronics from Mumbai University, India. His technical expertise spans cloud platforms, infrastructure as code, container orchestration, and comprehensive observability solutions. He is passionate about SRE best practices, having implemented incident response frameworks, post-mortem processes, and disaster recovery practices across regulated, high-traffic environments.
As an active member of the technical community, Sumit shares his expertise through his blog at medium.com/@sumit.kaul.87 and technical presentations. His work has consistently focused on creating "paved roads" that make secure, reliable practices the path of least resistance for development teams.
