Marvell’s semiconductor solutions are the essential building blocks of the data infrastructure that connects our world. Across enterprise, cloud and AI, and carrier architectures, our innovative technology is enabling new possibilities.

At Marvell, you can affect the arc of individual lives, lift the trajectory of entire industries, and fuel the transformative potential of tomorrow. For those looking to make their mark on purposeful and enduring innovation, above and beyond fleeting trends, Marvell is a place to thrive, learn, and lead.

Your Team, Your Impact

Be part of the team that’s redefining how a global technology leader secures its cloud and AI future. At Marvell, our Enterprise Security Engineering & Compliance group is where innovation meets protection — building and deploying next-gen security architectures that safeguard data across dynamic cloud, SaaS, and AI environments. From designing CASB strategies to securing the latest GenAI tools, you’ll work at the intersection of cutting-edge tech and real-world impact. If you’re passionate about staying ahead of evolving threats and enabling secure innovation at scale, this is where your expertise will make a difference.

We are seeking a highly skilled and motivated SaaS and Cloud Access Security Platform Engineer to join our Information Security team. This role will be pivotal in ensuring secure access to SaaS applications and safeguarding organizational data in the context of AI technologies. The ideal candidate will have deep expertise in CASB solutions, SaaS access security, data loss prevention, and developing robust security strategies to enable safe technology adoption.

What You Can Expect

Design, implement, operate, and support enterprise network security solutions across traditional, virtualized, and cloud environments, including routing, switching, segmentation, and traffic filtering technologies.

Serve as a subject matter expert for network security technologies, including firewalls, remote access solutions, IPSec VPNs, IDS/IPS, web application firewalls, proxies, DLP, CASB, NAC, micro-segmentation, wired and wireless security, SIEM, and next-generation breach detection platforms.

Design, deploy, and operate Palo Alto Networks SaaS Inline Security capabilities to provide real-time inspection, threat prevention, and data protection for SaaS application traffic.

Implement and manage Palo Alto Networks AI Access Security controls to secure enterprise usage of AI-driven and generative AI platforms, including policy enforcement, data loss prevention, and visibility into AI application usage and risk.

Integrate SaaS Inline Security and AI Access Security with existing Palo Alto Networks firewall platforms, CASB, DLP, and SIEM solutions to deliver a cohesive, end-to-end security architecture.

Define and enforce security policies for SaaS and AI application access aligned with corporate risk tolerance, data protection requirements, and industry best practices.

Monitor, analyze, and respond to security events and alerts related to SaaS and AI application traffic, performing investigation, tuning, and continuous optimization of controls.

Evaluate emerging SaaS and AI security features within the Palo Alto Networks ecosystem, advising on adoption, roadmap alignment, and operationalization across the enterprise.

Lead and contribute to network security initiatives from concept and architecture through implementation, testing, and production rollout, ensuring solutions align with business and security requirements.

Perform day-to-day operational support for network security infrastructure, including monitoring, troubleshooting, break-fix remediation, ticket handling, and change management in accordance with established processes and SLAs.

Provide expert-level troubleshooting of complex network and security issues at the protocol level (TCP/UDP, IP, ARP, DNS, HTTP/S), identifying root causes and implementing sustainable corrective actions.

Design, deploy, and maintain IPSec VPN solutions, including site-to-site and remote access, with a focus on scalability, security, and operational reliability.

Administer, design, and support Palo Alto Networks firewalls in on-premises, virtualized, and cloud-based environments; perform policy optimization, threat prevention tuning, upgrades, and lifecycle management.

Support and integrate complementary security platforms such as F5 WAF and McAfee CASB, ensuring seamless interoperability within the broader cybersecurity ecosystem.

Develop and maintain detailed technical documentation, network diagrams, security standards, and operational runbooks that reflect best practices and reference architectures.

Apply security control frameworks and methodologies (e.g., NIST, Cybersecurity Kill Chain) to architecture decisions, threat modeling, and remediation strategies.

Evaluate emerging cybersecurity technologies and vendors, objectively assessing technical capabilities versus marketing claims, and recommending solutions that provide measurable value and integrate effectively with existing systems.

Collaborate closely with cross-functional teams, including IT operations, cloud engineering, application teams, and security leadership, to ensure secure-by-design network architectures.

Use scripting and automation (Python required; Perl and Java a plus) to improve operational efficiency, enhance visibility, and reduce manual effort in network security operations.

Provide technical leadership, mentorship, and oversight for assigned projects or junior team members, promoting best practices and continuous improvement.

Stay current with evolving threat landscapes, attack vectors, and next-generation security platforms, proactively adapting defenses to address new risks.

Participate in on-call rotations and provide after-hours support as required to ensure the availability, integrity, and security of critical network infrastructure.
