Utilize Catos Data Warehouse with big-data technologies to support your work.

we are looking for a Senior Network Technical Lead to own the full technical lifecycle of network and security infrastructure projects - from requirements and design through implementation, customer acceptance, and handover
This is a technical-authority role, not a hands-on-keyboard-only position: the person sets direction for other engineers and is accountable for every design decision on the project.
Core Responsibilities
Own solution design end-to-end: translate customer requirements into secure, scalable network architectures, and produce HLD and LLD documentation.
Lead technical delivery - installation, configuration, migrations, and upgrades of enterprise network and security infrastructure.
Make and defend architecture and security design decisions spanning routing, switching, firewalling, and access control.
Lead FAT/SAT, customer acceptance, and technical handover, including as-built documentation.
Act as the primary technical point of contact for the customer for the duration of the project.
Set technical direction and mentor other engineers working on the project.
Identify and mitigate technical and security risk throughout the project lifecycle.
Coordinate with vendors and with the System and Cyber Security teams to ensure integrated delivery
Own and take an active part in integration work for projects both in Israel and abroad, including on-site involvement when required.

in this role, you will build and lead a team of validation engineers, owning the strategy, methodology, and execution of simulation-based validation frameworks that ensure our networking solutions meet the highest standards of quality, scale, and real-world applicability before reaching customers.
what you'll be doing:
leading and managing a team of network validation engineers responsible for end-to-end validation of our customer-facing networking solutions at scale, using a dedicated e2e simulation cluster environment.
defining the overall validation strategy and roadmap - establishing simulation methodologies, TEST coverage frameworks, and quality gates that align with product milestones and customer use cases.
pioneering the use of agentic ai flows within the validation organization - leading the team to design, build, and operate ai-driven agents capable of autonomously performing regression analysis, identifying coverage gaps, generating new TEST cases, and implementing validation code. these agentic workflows will continuously learn from simulation results and product changes, dramatically accelerating the team's ability to scale TEST coverage and respond to emerging quality signals without manual intervention.
overseeing the design and continuous improvement of automated regression suites for networking protocols and large-scale simulation runs, ensuring scalable, repeatable, and high-confidence validation outcomes.
establishing a rigorous regression analysis culture - guiding the team in identifying trends, root causes, and systemic coverage gaps, and ensuring timely resolution in collaboration with engineering stakeholders.
serving as the primary validation partner to design, architecture, and ncs teams - translating solution requirements into simulation scenarios, providing early-cycle quality feedback, and influencing product direction.
analyzing customer-reported networking solution issues, driving TEST gap analysis, and ensuring robust regression coverage that prevents recurrence.
staying current with emerging networking standards, simulation technologies, and industry best practices to continuously evolve the team's validation capabilities.
