Senior Network Security Engineer

We're looking for a senior level, hands-on Network Security Engineer to design, deploy, and secure our global corporate network across offices in North America and EMEA/APAC. You'll be the technical authority for secure networking architecture, driving automation, and ensuring our infrastructure is resilient, scalable, and vendor-agnostic. This role will partner closely with Corporate Technology, SRE, and Security Engineering and requires the ability to travel globally for deployments.

Who You Are

  • 8–10+ years in enterprise networking and network security, with multi-site design and operations experience.
  • Deep expertise in routing, switching, and segmentation; strong firewalling skills.
  • Proven experience with Cisco networking technology, especially Cisco Meraki.
  • Proficient in Python and Ansible for automation.
  • Skilled in NAC/RADIUS integrations with identity providers (Okta, Azure AD).
  • Strong understanding of certificate-based authentication, EAP, and zero-trust architectures.
  • Strong troubleshooting, documentation, and leadership skills.
  • Willing and able to travel internationally for deployments.

Nice to Have:

  • Cloud networking depth (AWS, Azure, GCP).
  • Experience with SASE/ZTNA platforms(Cloudflare/Zscaler).
  • Professional certifications (CCNP, CCIE, JNCIP, etc.).

What You'll Do

  • Architect and implement secure LAN/WAN/SD-WAN and Wi-Fi for multiple global offices.
  • Manage Cisco Meraki switches/routers/firewalls and APs, while staying vendor-agnostic for future integrations.
  • Deploy and manage network security controls including segmentation, NAC/802.1X, VPN, SWG/SASE, ZTNA, IDS/IPS, and DLP.
  • Implement and manage Wi-Fi EAP (Enterprise Authentication), certificate-based authentication, and enforce zero-trust access controls.
  • Plan and optimize enterprise Wi-Fi, including RF design, surveys, and performance tuning.
  • Build secure cloud and hybrid networking (AWS, Azure, GCP)
  • Automate deployments and configuration management with Python, Ansible, and IaC tools (Terraform, GitOps).
  • Implement observability and alerting; drive improvements in MTTR and service reliability.
  • Support compliance (SOC 2, ISO 27001) with secure configs, change control, and documentation.
  • Travel globally (approx. 25–40% during buildouts) for on-site deployments and architecture reviews.

Why Join Us?

  • Work on cutting-edge security challenges in a fast-growing company.
  • Opportunity to shape and drive product security strategy.
  • Collaborative and security-minded engineering culture.
  • Competitive compensation, benefits, and career growth opportunities.

If you're a hands-on security leader passionate about building secure products, we'd love to hear from you!
