Company mission
To help defend the world's most sensitive, mission-critical organisations.
Role
Who you are
- Proactive Problem-Solving: You are a proactive problem solver who doesn’t wait for instructions to address a bottleneck; you explore the "how" and "why" of system failures
- Collaborative Leadership: You have a proven ability to lead testing efforts across multiple teams, managing priorities effectively even when timelines or requirements are ambiguous
- Systems Thinking: You can visualize how complex network protocols and security insights interact across a geographically distributed, distributed-system architecture
- High-Fidelity Mentality: You take pride in being the final gatekeeper, ensuring that every release is robust enough to protect the mission-critical assets of our global customers
- Experience: 5–10 years of professional experience in Software Quality Engineering, SDET, or Systems Engineering roles
- Automation Mastery: High proficiency in Python and Bash for infrastructure automation and tool development
- Cloud & IaC Expertise: Hands-on experience with Ansible and Terraform, as well as production experience with at least one major cloud provider (AWS, Azure, or GCP)
- Networking Foundations: Deep working knowledge of Linux administration (RHEL/Ubuntu) and core protocols including TCP/IP, HTTP, DNS, and SSL/TLS
- SIEM Proficiency: Hands-on experience with security analytics tools such as Splunk, Elastic, or Microsoft Sentinel
- Education: Bachelor's degree in Computer Science or related fields, or equivalent professional experience
- Preferred Differentiators: Experience with Docker/Kubernetes, CI/CD pipeline optimization, or familiarity with Zeek, Suricata, and YARA
What the job involves
- As the Senior Software Quality Engineer for our Release Testing team, you serve as the critical final gatekeeper for our Open NDR platform. You will ensure that the actionable insights generated by Zeek, Suricata, and YARA are delivered with absolute reliability to our global customers
- By orchestrating complex, real-world network scenarios across cloud and on-prem environments, you bridge the gap between infrastructure and deep network analysis to ensure that defenders have a robust foundation to hunt threats and disrupt attacks
- Drive the End-to-End Testing Lifecycle: Act as the final technical authority on product quality, leading the strategy for stable, high-performance releases across multiple concurrent projects
- Architect Scalable Test Infrastructure: Design and maintain high-fidelity test environments across on-prem, virtual, and cloud platforms (AWS, Azure, GCP) using Infrastructure as Code (Ansible, Terraform)
- Develop Advanced Automation: Build and optimize sophisticated automated test frameworks and utility scripts using Python and Bash to ensure fast, reliable feedback loops
- Continuous Quality Integration: Manage test code within Git and seamlessly integrate automated suites into CI/CD workflows to modernize our release cadence
- Network Protocol Deep-Dive: Perform expert-level analysis of network traffic (TCP/IP, HTTP, DNS, SSL/TLS) to design realistic test scenarios that mimic sophisticated production environments
- Cross-Functional Triage: Partner with Development, Product Management, and the global QE organization to identify, prioritize, and resolve bottlenecks in the release pipeline
Our take
Corelight is a software company that integrates machine learning into cyber and cloud security. It develops NDRs (Network Detection and Response systems) alongside virtual, software and cloud sensors to better protect enterprises and institutions.
The company's most popular product is the Zeek Network Security Monitor, which is used by the likes of Amazon and Mozilla. It is also continually developing new products (such as a Cloud Sensor for Amazon Web Services) as the nature and complexity of cyber threats continue to grow.
Launched back in 2013, the company has been around for a while now, but it continues to keep up to date with the changing market. In 2024, Corelight secured immense Series E funding as it capitalises on the booming AI and cyber defense markets.
