Senior Site Reliability Engineer
Raoul Mahtani
I build reliable infrastructure, automate operational toil, and design systems that scale.
Currently a Senior Site Reliability Engineer at Flatiron Health, where I focus on infrastructure automation,
observability, and reliability engineering for healthcare systems.
Outside of work I build tools, experiment with distributed systems, and write about reliability engineering and system design.
About
I'm a Site Reliability Engineer focused on making complex systems predictable, observable, and easy to operate.
My work sits at the intersection of infrastructure automation, distributed systems, and reliability engineering.
I care about designing systems that are not only scalable, but also operationally simple and resilient under failure.
Professionally, I've spent the last several years working on:
- Infrastructure automation with Terraform
- Cloud architecture on AWS
- Reliability engineering using SLOs and observability
- Reducing operational toil through automation
At Flatiron Health I've worked on modernizing infrastructure, improving reliability, and reducing operational overhead
across production environments. Outside of my day job I build side projects focused on distributed systems,
developer tooling, and automation.
Work Experience
2022 – Present
Senior Site Reliability Engineer
Flatiron Health
- Led a migration from Ansible-based provisioning to Terraform-based Infrastructure as Code, modularizing infrastructure so entire client environments can be provisioned in minutes instead of weeks.
- Helped transition a critical healthcare application from monolithic infrastructure to a load-balanced architecture, dramatically improving system reliability.
- Implemented infrastructure optimization initiatives that reduced cloud spend by over $1M annually through right-sizing and usage analysis.
- Built automation and observability tooling to reduce operational toil and improve system visibility across production environments.
Jun 2017 – May 2022
Site Reliability Engineer
BlackRock
- Authored deployment playbooks and infrastructure automation using HashiCorp tooling (Terraform, Packer, Vault).
- Built Kafka consumers to surface real-time platform metrics for operational visibility.
- Delivered automation across Node.js/Cassandra/Angular services, reducing manual intervention in the deployment pipeline.
Jul 2014 – May 2017
GTI Rotational Analyst
BlackRock
- Administered enterprise Windows infrastructure and led storage zoning projects.
- Ran disaster recovery rehearsals for the East Coast data center.
Projects
Daedalus — Distributed Systems Project
A distributed agent platform designed for large-scale infrastructure introspection and automation.
The system allows a central control node to query and orchestrate thousands of agents across an infrastructure environment.
Key capabilities
- Horizontal scalability across thousands of nodes
- Secure agent registration using API key authentication
- Distributed command execution across infrastructure fleets
- Centralized query execution with aggregated results
- Web interface for issuing queries and monitoring node status
- Structured response collection and searchable history
Use cases
- Infrastructure inventory
- Fleet-wide diagnostics
- Operational automation
- Distributed command execution
Future iterations will include natural language queries translated into system commands using open-source language models.
Engineering Philosophy
The most valuable infrastructure systems share a few traits.
Automation first
If something must be done more than once, it should be automated.
Observability over guesswork
Reliable systems require good telemetry: logs, metrics, traces, and meaningful alerts.
Operational simplicity
The best systems are not the most complex ones — they're the ones that are easiest to run in production.
Failure is inevitable
Systems should be designed assuming things will break.
I write occasionally about reliability engineering, distributed systems, infrastructure automation, and building engineering tools.

I grew up in Jamaica and have always been interested in how complex systems work — whether that's infrastructure, software, or organizations.
Outside of engineering I enjoy traveling, fitness, writing, and exploring new places and ideas.
