Ready to join a mission that matters? The future of cybersecurity starts with you.

About the Role:

Our mission is to make all of our customers' security-relevant data continuously available for automated detection and response, threat hunting, and other Falcon platform use cases. To enable this, the systems behind NG-SIEM (next-generation security information and event management) are growing to accommodate >100 PB of event and action data ingested every day, up to 10 years of retention, and dozens of millions of queries per hour across large sections of the data stored, for tens of thousands of customers. As a Senior Engineer on the NG-SIEM Serverless Cell Platform team, you will be responsible for ensuring the health, performance, and reliability of cell infrastructure — operating the security industry's largest SIEM platform while building the automation and self-healing systems that enable it to scale seamlessly.

The NG-SIEM platform is built on a cell-based architecture where each cell is a self-contained LogScale cluster serving customer data. As we scale toward hundreds of petabytes per day, you will own the operational management of these cells through monitoring, incident response, capacity planning, and continuous improvement — while also developing automation systems that reduce toil and enable the fleet to self-heal. You will participate in follow-the-sun on-call rotations (8x7), perform version upgrades and scaling operations, optimize resource utilization, and write Go microservices that transform manual operational procedures into robust, automated workflows. You will join a distributed team of high-ownership technical leaders who share a strong passion for our mission: to stop breaches.

This role is based in Australia and is fully remote. Many team members are located in Sydney.

What You'll Do:

• Monitor and maintain the health, performance, and reliability of LogScale cells. Respond to incidents and participate in follow-the-sun on-call rotations with team support and clear escalation paths.

• Upgrade LogScale clusters and microservices using ring-based rollout strategies. Deploy patches, update configurations, and recover cells when failures occur.

• Build and maintain monitoring with defined Service Level Indicators. Implement alerting, synthetic test suites, and operational dashboards for rapid troubleshooting and root cause analysis.

• Write Go microservices and automation scripts that transform manual operational procedures into automated workflows, reducing toil and enabling self-healing capabilities.

• Work closely with product engineering and customer support teams to troubleshoot production issues and coordinate changes across the platform.

• Learn and grow through mentorship opportunities, knowledge-sharing sessions, and exposure to large-scale distributed systems engineering challenges.

What You'll Need:

• A passion for reliability engineering and operational excellence, with strong understanding of how large-scale distributed systems behave under pressure;

• 7+ years of experience in site reliability engineering, platform engineering, or infrastructure operations, with significant time operating and improving distributed systems at scale;

• Experience with capacity planning, resource optimization, and scaling operations for large-scale infrastructure;

• Proficiency in at least one programming language (Go, Python, Java, or similar) for writing automation scripts and microservices;

• Experience with cloud infrastructure (AWS, OCI, or GCP) including compute, storage, networking, and infrastructure-as-code (Terraform, Pulumi, or similar);

• A can-do attitude — you thrive collaborating in a team and are not afraid of taking on responsibilities;

• Strong written and verbal communication skills for writing runbooks, incident reports, and collaborating with teams across time zones;

• Ability to make pragmatic tradeoffs between operational stability and feature delivery needs.

• Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.

If you meet most but not all of these qualifications, we still encourage you to apply.

Bonus Points:

• Hands-on experience building monitoring systems, defining SLIs/SLOs, creating dashboards, and implementing alerting;

• Strong troubleshooting and root cause analysis skills across distributed system components;

• Experience operating database infrastructure, log management platforms, search systems, or SIEM platforms at scale;

• Track record of building automation that enables self-healing infrastructure and reduces operational toil;

• Experience with streaming platforms (Kafka or similar) and understanding of distributed data pipelines, backpressure, and partition management;

• Familiarity with containerization and orchestration (Kubernetes, Docker, or similar);

• Background in cybersecurity, security operations, or familiarity with security data workflows.
