Senior, Security Engineer- Infrastructure & Automation

Job Type Full-time Description Who We Are Scale Computing is a global leader in edge computing, hyperconverged infrastructure, and managed networking solutions. We deliver innovative, secure, and scalable technology that powers critical operations worldwide. Role Overview We are seeking a Security Engineer to join our growing security team, based in our Bengaluru office. This role is hands-on and technically focused — you will deploy, configure, and automate security tooling across our hyperscaler and on-premises infrastructure, working directly with the CISO to drive technical security initiatives. This is not a GRC, compliance, or analyst role. We are looking for an engineer who has built and configured security systems from the ground up — someone who has written scripts to automate controls, tuned detection rules, and gotten their hands dirty in cloud security consoles and infrastructure tooling. If your security experience is primarily policy-writing, audit support, or being a user of vendor dashboards, this role is not the right fit. Key Responsibilities Security Tooling Deployment & Configuration Deploy, configure, and maintain security tools across AWS, Azure, and on-premises environments Implement and manage SIEM platforms — log ingestion pipelines, parser development, and correlation rule authoring Configure and tune EDR/XDR platforms, vulnerability scanners, and network security tools Integrate security tooling with infrastructure via APIs and native connectors Own tool lifecycle: initial deployment, hardening, health monitoring, and version upgrades Security Automation & Alerting Build automation for security controls using Python, Bash, and/or PowerShell Develop and maintain detection rules, alerting logic, and correlation content Automate routine SecOps tasks: triage workflows, data enrichment, response actions Reduce alert fatigue through systematic tuning, suppression rules, and threshold calibration Build integrations between security tools and ticketing/ITSM systems (Jira, ServiceNow, or equivalent) Cloud & Infrastructure Security Implement and monitor cloud-native security controls: AWS Security Hub, GuardDuty, IAM; Azure Defender, Sentinel, Entra ID Apply and validate CIS benchmarks and hardening baselines across servers and endpoints Review and harden Infrastructure as Code configurations (Terraform, Ansible) Monitor network traffic and enforce segmentation policies Contribute to container and Kubernetes security posture: image scanning, admission control, runtime monitoring Detection & Response Engineering Develop detection content mapped to MITRE ATT&CK; Build and maintain runbooks for alert investigation and structured response Participate in incident response activities as a technical contributor Conduct threat hunting exercises using available telemetry Support purple team exercises and security tabletops Collaboration with CISO & Security Team Translate CISO direction into working technical implementations Document architecture decisions, tool configurations, and automation workflows Surface tooling gaps and propose solutions with clear tradeoff analysis Communicate technical findings clearly to non-technical stakeholders when needed Requirements Experience 4–7 years in a hands-on security engineering or security operations engineering role Demonstrated experience building or configuring security tooling — not just operating vendor dashboards Hands-on experience in at least one cloud environment (AWS or Azure) with native security services Scripting proficiency: Python and/or Bash required; PowerShell a plus Hands-on SIEM experience: Elastic Security, Splunk, Microsoft Sentinel, or equivalent — detection rule development, not just querying Experience with vulnerability management tooling (Tenable, Qualys, Rapid7, or equivalent) at an administrative/configuration level Strong written and verbal English communication skills Technical Skills Cloud: AWS (Security Hub, GuardDuty, IAM, CloudTrail, Config) or Azure (Defender for Cloud, Sentinel, Entra ID, NSGs) SIEM: Detection engineering, log source onboarding, parser/pipeline development Scripting: Python and/or Bash — automation, API integration, tool-building Endpoint security: EDR/XDR administrative configuration and alert tuning Network security: Firewall policy review, IDS/IPS tuning, network traffic analysis IaC: Terraform or Ansible at a review and hardening level (greenfield dev is a plus, not required) Preferred Certifications One or more of the following preferred: GIAC certifications: GCIH, GCIA, GCED, GDAT, or GREM AWS Certified Security – Specialty Microsoft SC-200 (Security Operations Analyst) CompTIA CySA+ (baseline acceptable; not a differentiator on its own) Practical, portfolio-backed experience — home labs, CTF competition results, open-source tool contributions — will be weighted alongside or above certifications. Education Bachelor's degree in Computer Science, Information Technology, Cybersecurity, or a related field, or equivalent practical experience. Perks of Scale Computing Group medical insurance.
