We are seeking a highly motivated Site Reliability Engineer (SRE) with more than 7 years of experience to manage, scale, and ensure the high availability of our core infrastructure. This role is designed for experts specialized in AWS. You will leverage a profound background in Linux (specifically RHEL) to drive deep-level cloud architecture, automation, complex networking, and security compliance, supporting a high-volume, mission-critical environment that demands exceptional uptime and resilience.

Roles and Responsibilities

• Lead advanced Linux/RHEL administration, focusing on OS troubleshooting, kernel-level performance tuning, and executing security hardening for high-volume, mission-critical environments.

• Build and scale highly available AWS environments that can handle massive traffic without failing. Drive the long-term strategy for our servers, data storage, and system monitoring.

• Architect infrastructure with a strong emphasis on High Availability (HA) and robust Information Security. Set and drive the adoption of security standards and compliance best practices across the infrastructure.

• Design and maintain advanced network connectivity and routing using AWS Direct Connect, Transit Gateways, VPNs, and BGP

• Plan, strategize, and oversee large-scale infrastructure migrations, component upgrades, and database sharding while ensuring minimal to zero disruption to production

• Lead capacity planning for organic growth and traffic spikes.

• Define the best practices and tools we use for Infrastructure as Code (IaC) and configuration management. Continuously reduce manual toil by designing automated, self-healing systems.

• Design and implement cross-region database replication, HA scaling strategies, and comprehensive disaster recovery plans for data stores like MySQL and Aerospike.

• Establish and track our reliability metrics. Lead the response during production outages, and use post-mortems (RCAs) to fix underlying architectural flaws and reduce technical debt

• Establish documentation standards for system architecture, disaster recovery plans, and SOPs. Mentor fellow team members and foster a collaborative culture of reliability and continuous learning.

Minimum Requirements

• Experience: 7+ years as a Senior SRE, Cloud Architect, or Lead Systems Engineer.

• Advanced proficiency in Linux/RHEL administration, including hands-on troubleshooting, kernel-level performance tuning, and OS security hardening.

• Deep, architectural-level expertise exclusively within the AWS ecosystem.

• Strong understanding of BGP routing, complex TCP/IP troubleshooting, and large-scale network design.

• Understanding of MySQL/MariaDB/Percona or any other relational database concepts and administration

• Proven experience defining and tracking site reliability, alongside a strong passion for automation.

• Proven ability to scale and optimize load balancers (Nginx, HAProxy) to handle massive web traffic.

• Hands-on experience orchestrating and scaling containerization technologies (Docker, Podman, or equivalent).

• Ability to effectively communicate complex technical strategies and architectural decisions to internal teams and external stakeholders.

Preferred Qualifications (A Plus)

• Experience optimizing cloud costs - finding wasted resources and cutting AWS bills without sacrificing performance.

• Knowledge of NoSQL databases like Aerospike

• Experience with distributed event streaming platforms like Kafka.

• Experience predicting future infrastructure needs and planning capacity for long-term growth.
