Job summary

Scale Computing is seeking a Security Engineer to join our Bengaluru security team. This hands-on role focuses on deploying, configuring, and automating security tooling across cloud and on‑prem environments, working directly with the CISO to drive technical security initiatives.

If your strength lies in building security controls rather than policy work, this is the right fit. You will own tool lifecycle, integrate with infrastructure via APIs, and develop detection content mapped to MITRE

Qualifications

• Hands-on security tooling build/configuration, not just dashboards.
• Experience in at least one cloud environment (AWS or Azure) with native security services.
• Proficient in scripting for automation (Python, Bash; PowerShell a plus).

Responsibilities

• Deploy, configure, and maintain security tools across AWS, Azure, and on-prem environments.
• Build and tune detection rules and alerting logic; implement secure pipelines and APIs.
• Develop and maintain runbooks, respond to incidents, and support threat hunting.

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 tuningNetwork 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.
