About the Role
As a Senior Network Security Engineer at Altera, you will serve as a senior technical authority responsible for defining and advancing the enterprise network security strategy, architecture, and technical roadmap across on-premises, cloud, data center, laboratory, campus, WAN, and hybrid environments. You will architect secure, resilient, and scalable network solutions grounded in Zero Trust, least-privilege access, micro-segmentation, and secure-by-design principles, while providing technical leadership across firewalls, ZTNA, SASE, SD-WAN, NDR, IDS/IPS, network telemetry, and security automation.
This role combines deep hands-on engineering expertise with strategic architecture ownership and cross-functional influence. You will partner closely with Network Engineering, Cloud, Infrastructure, DevOps, Product Security, and Risk teams to translate security requirements into implementable designs, serve as a senior escalation point for complex security incidents and architecture decisions, and drive measurable improvements in attack-path reduction, segmentation, rule hygiene, visibility, resilience, and overall security posture. You will also help establish engineering standards, reference architectures, governance practices, and repeatable processes while mentoring engineers and communicating complex technical risks and recommendations to both technical and executive audiences.
Responsibilities:
Technical Strategy & Architecture Ownership
Define and evolve Altera’s enterprise network security strategy, target-state architecture, technical roadmap, and reusable reference patterns.
Serve as the senior technical authority for complex network security decisions, design exceptions, and modernization initiatives.
Drive adoption of Zero Trust, least-privilege access, micro-segmentation, and secure-by-design network principles.
Establish architecture standards, decision criteria, and measurable outcomes for attack-path reduction, rule hygiene, segmentation coverage, resilience, and network visibility.
Network Security Architecture & Engineering
Architect and review secure designs for data center, campus, laboratory, cloud, WAN, remote-access, and hybrid environments.
Design segmentation and traffic-control models using security zones, VRFs, next-generation firewalls, secure routing, identity-aware access, and workload-level controls.
Evaluate and guide adoption of ZTNA, SWG, SASE, SD-WAN, NDR, IDS/IPS, firewall, and network-security automation capabilities.
Partner with network, cloud, platform, product security, and operations teams to translate security requirements into implementable designs.
Validate architecture through design reviews, configuration analysis, packet and flow analysis, resilience testing, and post-implementation verification.
Conduct ongoing firewall administration and operations including policy lifecycle management, rule administration, hardening, and exception governance.
Threat Detection, Monitoring, & Incident Response
Provide senior technical expertise during investigations involving network intrusion, lateral movement, command-and-control activity, privilege misuse, and data exfiltration.
Design and improve network telemetry, logging, detection coverage, and correlation across SIEM, NDR, firewalls, proxies, DNS, VPN, and cloud network services.
Perform or guide packet capture, flow analysis, protocol troubleshooting, and root-cause analysis for complex security events.
Act as a technical escalation point during major incidents and translate findings into architecture improvements, detection enhancements, and remediation plans.
Risk Management, Governance & Compliance
Perform security architecture and risk assessments for new systems, cloud services, network changes, and exceptions.
Author and maintain network security standards, reference architectures, technical guidelines, and control requirements.
Align designs with relevant frameworks and requirements,…
