Senior Network Security Engineer at AlphaSense

The Senior Network Security Engineer will architect and implement secure LAN/WAN/SD-WAN and Wi-Fi solutions for global offices, managing Cisco Meraki devices while maintaining vendor-agnosticism for future integrations. Responsibilities include deploying and managing network security controls such as segmentation, NAC/802.1X, VPN, SWG/SASE, ZTNA, IDS/IPS, and DLP. The role involves implementing and managing Wi-Fi EAP, certificate-based authentication, and enforcing zero-trust access controls, as well as planning and optimizing enterprise Wi-Fi through RF design and performance tuning. Building secure cloud and hybrid networking environments in AWS, Azure, and GCP is key, along with automating deployments and configuration management using Python, Ansible, and IaC tools. The engineer will implement observability and alerting to improve MTTR and service reliability, support compliance requirements like SOC 2 and ISO 27001 through secure configurations, change control, and documentation, and travel globally for on-site deployments and architecture reviews.
