• Deploy, maintain, and optimize cloud-based data infrastructure on AWS • Own CI/CD pipelines, infrastructure automation, and monitoring • Ensure platform stability, observability, and scalability • Support the transition from single-client to multi-client architecture • Work closely with the founder and data engineers to move fast and safely

• Design and evolve Azure platform infrastructure with a focus on scalability, reliability, and growth readiness. • Participate in capacity planning to support growth, peak demand, and seasonal usage patterns. • Integrate with development resources to implement infrastructure-as-code (e.g., Bicep). • Troubleshoot production infrastructure issues and lead incident response efforts, including coordination, escalation, and real-time remediation across teams. • Conduct post-incident reviews (postmortems) focused on root cause analysis, corrective actions, and long-term reliability improvements rather than blame. • Monitor and operate production systems using Azure Monitor, Application Insights, Sentinel, and related observability tooling. • Improve system reliability and performance through alerting, error monitoring, SLOs/SLAs, and analysis of performance and capacity trends. • Collaborate with security analyst to define and implement security controls across Azure resources and pipelines. • Manage secrets, certificates, and identity integrations. • Automate security posture checks in CI/CD pipelines. • Maintain policy-as-code using Azure Blueprints or Defender for Cloud Compliance & Audit Support. • Support SOC 2 Type II compliance through tooling, automation, and audit readiness. • Respond to evidence requests and generate reports from observability and security systems. • Contribute to the documentation of platform controls and best practices. • Support, maintain, and own CI/CD pipelines (GitHub Actions, Azure DevOps, or equivalent). • Optimize build, test, and release flows, partnering with engineers to diagnose failures and improve deployment reliability. • Define and maintain consistent environment standards across development, staging, and production to ensure deployment safety, reliability, and compliance. • Partner with engineering teams to improve deployment promotion strategies, rollback mechanisms, and release safety practices.

• Own the reliability, scalability, and operability of our shared platform and production systems • Operate and evolve large-scale distributed systems • Lead the design, build, and implementation of automation, orchestration, and operational tooling • Set technical direction and influence platform strategy • Establish and enforce standards, operational rigor, and best practices • Lead the adoption and execution of modern CI/CD, GitOps, and cloud-native infrastructure practices • Mentor and develop senior and staff engineers • Collaborate closely with product and engineering stakeholders

• Support engineering teams by maintaining and improving the high-frequency trading (HFT) platform across multiple cloud and On-Prem environments. • Work on network, operation system and application to achieve ultra-low latency and high system reliability. • Enhance the developer experience by introducing modern tools, automation, and best practices across infrastructure and development workflows. • Explore and implement new technologies to further optimize infrastructure performance and scalability.
