Job Title: Senior Infrastructure Security Architect

Location: India
Reports To: Security & Infra Director

We are seeking a highly experienced Senior Infrastructure Security Architect to lead the security architecture of our global enterprise infrastructure. The role will focus on designing, governing, and continuously improving security across networks, identity, endpoints, data centers, hybrid cloud, remote access, monitoring, and resilience domains. The architect will partner closely with IT, Infrastructure, Security Operations, SOC, Cloud, and R&D teams to ensure secure, scalable, and practical architectures across corporate, production, and engineering environments.

Key Responsibilities

• Architecture & Design

oOwn and lead infrastructure security architecture across global sites, hybrid cloud, data centers, corporate networks, endpoints, identity platforms, remote access, and operational technology where applicable

oDefine and govern security architecture for network segmentation, Zero Trust access, firewalls, VPNZTNA, SD-WANSASE, IAM, PAM, endpoint protection, cloud connectivity, logging, monitoring, and secure administration.

oEstablish infrastructure security standards, reference architectures, patterns, and guardrails for globally distributed IT, cloud, and R&D environments.

oDrive secure infrastructure design for mergers, new sites, data center changes, cloud migrations, branch connectivity, and major technology refresh programs.

oReview and approve infrastructure designs to ensure secure-by-design principles, operational resilience, least privilege, observability, and compliance requirements are embedded from the start.

oDevelop scalable, secure, and resilient infrastructure solutions for hybrid, multi-cloud, and globally distributed environments.

oEnsure infrastructure architecture aligns with security frameworks, regulatory requirements, audit expectations, and internal risk management standards.

·Application & AI Security Architecture

oSupport application security architecture reviews for new platforms and major engineering initiatives, ensuring alignment with enterprise infrastructure security principles

oContribute to security architecture for AI/ML systems, including LLM-based applications, RAG pipelines, AI agents, and the underlying infrastructure, identity, data access, and monitoring controls that support them.

oDefine governance and guardrails for internal and third-party AI tool adoption.

oAssess risks across the AI supply chain, including third-party models, APIs, and training data provenance.

• Establish AI-specific incident response procedures.
• Architect API security (authentication, rate limiting, gateway-level protections, API discovery/inventory).
• Define application-layer threat modeling practices (e.g., STRIDE) as a standard part of design reviews.

·Infrastructure Security Leadership

oDefine and enforce infrastructure security frameworks, policies, baselines, hardening standards, and architecture review processes.

oAnalyze and mitigate security risks across infrastructure platforms, cloud services, identity systems, endpoints, networks, and business-critical applications.

oTranslate threat intelligence, incident learnings, audit findings, and vulnerability trends into practical infrastructure architecture improvements.

oCollaborate with SOC and IT teams to strengthen cybersecurity posture.

oPartner with infrastructure and operations teams to improve backup security, disaster recovery readiness, privileged administration, secure remote access, asset visibility, and configuration management.

• Strategic Advisory
  • Act as a trusted advisor to executive leadership on technology trends and risks.
  • Evaluate emerging technologies and recommend adoption strategies.

oLead infrastructure architecture reviews and governance processes for strategic technology initiatives.

Qualifications

• Experience:

o10+ years in infrastructure security, security architecture, network security, identity security, cloud security, and enterprise IT security.

oProven experience architecting and securing global enterprise infrastructure across multiple regions, sites, data centers, cloud platforms, and hybrid environments.

oDeep hands-on background in network security, identity and access management, PAM, endpoint security, cloud security, virtualization, storage, backup, monitoring, SIEM, XDR, vulnerability management, and security operations.

oWorking knowledge of application security, API security, threat modeling, secure SDLC, and vulnerability management.

oExtensive experience working with R&D, DevOps, and product engineering teams.

oExperience or strong familiarity with AI security concepts, including LLM applications, AI agents, RAG architecture, data protection, model/API risk, and AI governance.

oExtensive experience leading large-scale IT security projects end to end.

oStrong experience with Zero Trust, SASE/SSE, network segmentation, secure remote access, firewall architecture, secure administration, and infrastructure hardening.

oAbility to create security architecture diagrams, standards, design reviews, risk assessments, and implementation guidance for infrastructure and cloud teams.

oHands-on experience with Linux and Windows based platforms.

oHands-on experience with firewalls, SIEM, XDR, CASB, DLP, EDR, vulnerability scanners, patch management, backup security, and configuration management tools.

oExperience with monitoring, automation and orchestration systems.

oExperience with securing R&D environments.

oCertifications: CISSP, CCSP, CCNP/CCIE Security, AWS/Azure Security or Architect, TOGAF, SABSA, or equivalent experience.

• Skills:

§Strong ability to balance security requirements with operational feasibility, business continuity, performance, and global scale.

§Strong analytical, leadership, and communication skills.

§Excellent spoken and written English.

§Ability to influence technical teams without direct authority and translate security requirements into practical engineering controls.
