Join to apply for the Senior Information Security Engineer role at Westfield Insurance

We're looking for a hands-on Senior Information Security Engineer to join our growing security team. In this role, you won’t just be responding to alerts—you’ll help design, build, and refine the tools, controls, and processes that protect our company. This is a senior-level engineering role focused on making a direct impact on our enterprise security posture, working across network, cloud, endpoint, and application layers. You’ll be part of a collaborative environment where you’ll lead complex initiatives, contribute to our security strategy, and help level up the team.

You’ll be working in a hybrid IT environment (on-prem and cloud), with an emphasis on security automation, network and endpoint protection, and other security platforms/tooling. This is an opportunity to be part of a mature yet evolving security organization where your technical input matters.

What You'll Work On

• Lead the design and deployment of security tooling, including firewalls, intrusion prevention systems, EDR, DLP, and cloud-native controls
• Build and maintain security automation around threat detection, response, and compliance reporting
• Partner with infrastructure, app dev, and cloud teams to embed security into projects and platforms
• Evaluate, test, and implement new tools and capabilities based on threat landscape and internal needs
• Collaborate with the Security Architecture team by providing technical input and context during architecture reviews, threat modeling, and risk assessments to ensure practical, implementable security controls
• Drive continuous improvement of existing security controls—identifying gaps, tuning configurations, and retiring legacy solutions
• Support the SOC during incident response by providing infrastructure and tooling expertise, assisting with containment efforts, and implementing post-incident improvements
• Mentor junior staff and contribute to team development through documentation, process design, and knowledge sharing

Relevant Skills and Experience

• NGFWs, IDS/IPS, WAFs, proxies, micro segmentation, and VPNs (e.g., Palo Alto, F5, VMware NSX)
• Endpoint protection and management tools (e.g., Sentinel One, Microsoft Defender for Endpoint, CrowdStrike)
• Cloud platforms (AWS and Azure) with a focus on secure configurations and native security services
• Email security tools (e.g., Checkpoint, Proofpoint, Mimecast)
• Microsoft Sentinel (SIEM) and SOAR; contribute to detections and automation in collaboration with the SOC
• Scripting and automation using Python, PowerShell, or Bash
• DevSecOps practices and tools (e.g., Azure DevOps) for automation, CI/CD, and infrastructure-as-code workflows

What We're Looking For

• Deep knowledge of enterprise security tools and frameworks (e.g., NIST CSF, CIS Controls)
• Experience integrating security controls into hybrid IT environments (on-prem + cloud)
• Ability to communicate effectively with technical and non-technical teams
• Ability to think strategically, execute tactically, and stay hands-on with tools

Bonus Points for These Certifications or Similar Experience:

• CISSP, CCSP, Security+ or AWS/Azure security certifications
• Experience building security automation or integrations between tools using APIs or scripting
• Background in network engineering or systems administration
• Experience influencing and implementing endpoint security, including EDR tuning, hardening standards, and collaboration on Group Policy or device management tooling (e.g., Intune, SCCM)

Why You’ll Want This Job

• Impactful work: You’ll help shape how security is done at an enterprise level
• Strong team culture: We value collaboration, ownership, and continuous learning
• Balance of autonomy and support: You’ll have the freedom to engineer solutions and the support to get things done
• Commitment to growth: We invest in the professional development of our engineers

Security Domains

• Vulnerability Management
• Network Security
• Firewalls
• Security Assessments
• Security Monitoring
• Identity Management
