Network Security Consultant- Part Time

Tufin is building AI tools that assist network security engineers in their daily work. To do this well, we need to deeply understand what network security engineers actually do: the tasks, the decisions, the pain points, the tools they use, the systems they get their data from and the domain knowledge that defines the craft.

We are looking for a senior network security engineering practitioner, who can serve as the domain authority for this initiative. You will work closely with our product managers and AI teams to define the network security engineer persona, articulate their workflows, and help design AI tools that reflect real-world expertise.

What You'll Do

• Define the day-to-day tasks and workflows of network security engineers in enterprises across industries such as banking, insurance, retail, manufacturing, IT, telco, and airlines -- capturing how these vary by industry and organization size.
• Articulate the network security engineer persona: their goals, challenges, tools, data, decision-making patterns, and the tribal knowledge they carry.
• Collaborate with product managers and AI engineers to translate domain knowledge into agent capabilities, use cases, and acceptance criteria.
• Advise on the technical accuracy and real-world relevance of agent behaviors across areas including: firewall, cloud and SASE network security, policy management and rule recertification, compliance and audit readiness, vulnerability management, application connectivity and change requests, network troubleshooting, policy cleanup and security issues triage.
• Review and critique agent outputs, providing expert feedback to improve precision and coverage.
• Help build and validate test scenarios grounded in real enterprise environments.

*** Position Type: Part-Time (50%) | 6-Month Temporary Position (with potential for extension) ***

• 8+ years as a senior network engineer or network team lead at a large enterprise or service provider.
• Deep hands-on expertise in firewall management (policy design, rule lifecycle, recertification, cleanup) and network security operations.
• Experience working in regulated or complex environments -- ideally in a global organization providing financial services, insurance, telco, manufacturing, or a similarly demanding sector.
• Strong familiarity with modern network architectures including cloud networking (AWS, Azure, GCP), SASE, SD-WAN, and hybrid environments.
• Experience with leading firewall and security platforms (e.g., Palo Alto, Check Point, Fortinet, Cisco) and network security tools.
• Background in compliance frameworks, vulnerability management, and change management processes as they apply to network infrastructure.
• Familiarity with Tufin or competitor products is an advantage.

Skills & Attributes

• Exceptional written and verbal communication -- able to explain complex technical workflows to non-technical stakeholders and vice versa.
• Strategic thinker who can see the big picture: how individual tasks fit into the broader operating model of a network security team.
• Able to structure and document institutional knowledge in a way that can inform AI agent design.
• Collaborative, curious, and comfortable working at the intersection of networking, security, and product development.
• Able to work in a fast-paced environment with frequent context switching, brainstorming and experimenting.
• Based in the US; familiarity with the regulatory and operational landscape in those regions is a plus.
