About The Team

Join Cloudflare’s Security Team in Bangalore. We seek motivated students in Cybersecurity, Computer Science, or Information Systems for a cross-functional role. This position offers hands-on experience across multiple security domains, including GRC, IAM, Appsec, and Sec Arch, to help build a safer internet.

About the role/What You’ll Do

Provide input on security requirements for new infrastructure and engineering initiatives.
Assist with documentation and maintenance of the corporate security architecture blueprints
Your focus will be on hardware security ,secure boot processes, side-channel attack mitigation, BIOS level security requirements and cryptographic isolation within devices, etc.
Partner with hardware and firmware teams to provide security guidance for the design and implementation of security features such as Hardware Root of Trust (RoT), Secure Boot (e.g., UEFI configuration), and hardware-based cryptographic accelerators.
Define advanced memory protection strategies.
Collaborate with the Security Detections and Monitoring team to develop telemetry and alerts for detecting unauthorized hardware changes, firmware tampering, or suspicious BIOS/UEFI configuration modifications.
Define and enforce secure configuration standards for BIOS/UEFI settings, Trusted Platform Modules (TPM), and physical port management (e.g., USB, JTAG, UART) to prevent unauthorized access.
Coordinate 3rd party hardware and firmware penetration tests, review technical findings, and translate complex vulnerabilities into actionable security requirements for engineering teams.
Design secure solutions for complex infrastructure problems, such as implementing Zero Trust principles at the hardware level and securing high-performance computing or edge-device integrations.
Perform regular audits of hardware and firmware environments to identify "configuration drift" where systems have deviated from established security baselines or approved firmware versions.
Evaluate vendor updates, microcode patches, and vulnerability data (CVEs) to make prioritized risk-based recommendations for patching critical hardware flaws.
Act as the security liaison between infrastructure, firmware, and other engineering teams to embed "secure-by-design" principles into the early stages of the hardware procurement and development lifecycle.
Conduct detailed threat modeling sessions specifically focused on physical attack vectors, side-channel attacks, and supply chain integrity risks.
Provide deep technical expertise during hardware-related security incidents, assisting with forensic analysis of compromised firmware or physical tampering detected by monitoring systems.
Develop hardware-specific security policies and reference architectures that comply with international standards such as NIST SP 800-193 (Platform Firmware Resiliency).

Requirements

Either advanced studies in Cybersecurity, Computer Science, Information Systems, or similar
Excellent written and verbal communication skills, including the ability to effectively collaborate with technical and senior business staff and management.
12+ years in a product or embedded security role, with 7+ years as a Hardware Security Architect.
Expertise in Medium to high-level security concepts, including secure boot, memory protection, and secure element implementation.
Proficiency with hardware description languages and hands-on experience with hardware/firmware vulnerability assessment and penetration testing.
Strong knowledge of security standards relevant to device manufacturing and supply chain

Preferred

Certifications: CSSLP or relevant vendor-specific hardware security certifications.
Experience with open-source hardware architectures.

Background in securing IoT, industrial control systems (ICS), or consumer electronics devices.

What Makes Cloudflare Special?

We’re not just a highly ambitious, large-scale technology company. We’re a highly ambitious, large-scale technology company with a soul. Fundamental to our mission to help build a better Internet is protecting the free and open Internet.

Project Galileo: Since 2014, we've equipped more than 2,400 journalism and civil society organizations in 111 countries with powerful tools to defend themselves against attacks that would otherwise censor their work, technology already used by Cloudflare’s enterprise customers--at no cost.

Athenian Project: In 2017, we created the Athenian Project to ensure that state and local governments have the highest level of protection and reliability for free, so that their constituents have access to election information and voter registration. Since the project, we've provided services to more than 425 local government election websites in 33 states.

1.1.1.1: We released 1.1.1.1 to help fix the foundation of the Internet by building a faster, more secure and privacy-centric public DNS resolver. This is available publicly for everyone to use - it is the first consumer-focused service Cloudflare has ever released. Here’s the deal - we don’t store client IP addresses never, ever. We will continue to abide by our privacy commitment and ensure that no user data is sold to advertisers or used to target consumers.
