About The Position

The Senior Cyber Security Engineer is a highly skilled, hands-on technical contributor responsible for engineering, deploying, administering, and continuously improving enterprise security technologies that protect both Corporate Computing (team member endpoints) and Enterprise Computing environments (on‑prem, cloud, and hybrid). In this role, you will apply deep security engineering expertise, modern automation practices, and strong platform ownership to help ensure our security controls are resilient, scalable, and effective against evolving threats. You will collaborate closely with engineering, architecture, SOC, cloud, IAM, and product teams to embed security into platforms, services, and workflows. This role is ideal for an experienced security engineer who thrives at the intersection of Security Engineering, DevSecOps, cloud security, platform automation, and emerging AI‑driven capabilities, and who enjoys solving complex technical problems at scale.

Requirements

• Bachelor’s degree in a related discipline and 4 years’ experience in a related field. The right candidate could also have a different combination, such as a master’s degree and 2 years’ experience; a Ph.D. and up to 1 year of experience; or 16 years’ experience in a related field
• 4 years of experience in Cyber Security Engineering, Security Architecture, Platform Engineering, or related disciplines.
• Strong hands-on experience administering and engineering major security platforms (e.g., EDR, SASE, ZTNA, Email Security, Network Firewalls, SIEM/SOAR, KMS).
• Demonstrated experience automating infrastructure and security tooling using Terraform, CI/CD pipelines, GitOps, and scripting languages (Python preferred).
• Solid understanding of cloud platforms, identity security, endpoint security, and zero‑trust architectures.
• Experience contributing to secure enterprise architectures at scale.
• Strong communication skills and the ability to collaborate effectively with cross‑functional engineering teams.

Nice To Haves

• Experience applying AI or automation to security operations, detection engineering, or cloud security workflows.
• Hands-on experience with EDR tuning, DLP policy engineering, cloud workload protection, and modern SIEM/SOAR pipelines.
• Security or cloud certifications such as CISSP, CCSP, GCSA, GCPN, GCIA, or vendor-specific credentials.

Responsibilities

• Security Tooling Engineering, Deployment & Administration Engineer, deploy, configure, tune, and maintain core security platforms including EDR, SASE, ZTNA, Email Security, Network Firewalls, DDoS, SIEM, SOAR, Firewall Audit, KMS, and related endpoint, network, data protection, and cloud security technologies.
• Support lifecycle activities such as upgrades, feature adoption, performance tuning, and operational improvements across security platforms.
• Evaluate and test new vendor capabilities and enhancements, partnering with senior engineers and architects to operationalize improvements.
• Contribute to scalable, resilient architectures for endpoint and enterprise security systems across on‑prem, cloud, and SaaS environments.
• Automate security infrastructure provisioning, configuration, and policy deployment using Terraform, Git-based workflows, CI/CD pipelines, and DevSecOps practices.
• Develop and maintain reusable modules, pipelines, and templates that standardize how security controls are deployed and integrated.
• Contribute to Security‑as‑Code and Policy‑as‑Code initiatives that embed security guardrails into engineering workflows.
• Partner with engineering, cloud, and platform teams to provide hands-on security engineering guidance and design input.
• Contribute to secure-by-default patterns, architecture standards, reference implementations, and best practices.
• Identify security control gaps and work collaboratively to design pragmatic, scalable solutions.
• Apply AI and automation techniques to reduce manual effort, improve operational efficiency, and enhance security tooling integrations.
• Contribute to internal automation initiatives that support SOC workflows, threat investigation, identity security, and data protection.
• Assist with the evaluation and operational use of AI/ML features within security tools (e.g., risk scoring, behavioral analytics, anomaly detection).
• Participate in proofs of concept (POCs), feature evaluations, and capability assessments across the security stack.
• Help develop dashboards, metrics, and telemetry that measure security control health, effectiveness, and drift.
• Collaborate with SOC and threat intelligence teams to align engineering improvements with real-world threat activity.
• Engineer and support security controls across: Corporate Computing: team member endpoints (Windows, macOS, Linux), secure remote access, identity and access workflows Enterprise Computing: datacenter infrastructure, cloud platforms (AWS, Azure, GCP), containers/Kubernetes, and hybrid workloads
