About Quantanite

Quantanite is a customer experience & digital outsourcing solutions company helping fast-growing businesses & global brands transform operations through intelligent automation, GenAI, & exceptional people.

About the Role

We are seeking a Senior Azure AI Security Engineer to lead hands-on security implementation across Quantanite's application, cloud, & AI infrastructure estate.

As we build & deploy AI-powered platforms on Azure, this role will ensure security is embedded across the development lifecycle, deployment pipelines, & infrastructure design. You'll design, implement, & continuously improve controls across software, data, cloud, & AI layers.

This is an engineering-first role for a practitioner who can threat-model AI systems, harden Kubernetes & Azure environments, build secure CI/CD pipelines, & guide engineering teams on secure coding practices.

Key Responsibilities

1. Application & Software Security

• Embed security controls throughout the software development lifecycle (SDLC) — from design reviews & threat modelling to code scanning, testing, & post-deployment monitoring.
• Implement & manage SAST (Static Application Security Testing), DAST (Dynamic Application Security Testing), & SCA (Software Composition Analysis) tooling within CI/CD pipelines.
• Define & enforce secure coding standards & conduct security-focused code reviews across application teams.
• Implement & manage secrets management, certificate lifecycle management, & key rotation practices.
• Design & enforce authentication & authorisation frameworks: OAuth 2.0, OIDC, RBAC, & least-privilege access patterns across applications.
• Own vulnerability assessment & remediation across application components — identifying, prioritising, & tracking fixes to closure.
• Implement & maintain Web Application Firewall (WAF) rules, API security gateways, & input validation controls.

2. AI Security Controls

• Define & implement security controls specific to AI/ML systems: model access controls, prompt injection defences, adversarial input handling, & output validation.
• Implement data security for AI pipelines — including per-tenant data isolation, encryption-at-rest & in-transit (AES-256, TLS 1.3/mTLS), & secure data ingestion from external client sources.
• Design & enforce data governance controls for AI training & inference environments: data lineage, access logging, & retention policy enforcement.
• Assess & mitigate risks specific to LLM & GenAI deployments: model inversion attacks, data leakage through model outputs, jailbreak vectors, & supply chain risks in AI frameworks.
• Establish security review processes for AI model deployment, including model signing, registry security, & inference endpoint hardening.
• Collaborate with AI/ML engineers to ensure RAG pipelines, vector databases, & agentic workflows are built with security-first design principles.
• Stay current with evolving AI security standards & frameworks (e.g. OWASP LLM Top 10, MITRE ATLAS, NIST AI RMF) & translate these into actionable controls.

3. Azure Cloud Infrastructure Security

• Design & implement a secure Azure landing zone: VNet architecture, Network Security Groups (NSGs), Azure Firewall, Private Endpoints, & subnet segmentation.
• Implement & manage Azure Security Centre / Microsoft Defender for Cloud — continuously monitoring posture, alerts, & compliance scores.
• Harden Azure PaaS services: Azure App Service, Azure Kubernetes Service (AKS), Azure Container Registry, Azure API Management, Azure SQL, & Azure Data Lake Storage.
• Manage Azure Active Directory / Entra ID: Conditional Access policies, Privileged Identity Management (PIM), managed identities, & service principal governance.
• Implement & maintain Azure Key Vault for secrets, certificates, & encryption key management across all environments.
• Design & enforce Infrastructure as Code (IaC) security practices — security policy-as-code, automated scanning of Terraform/Bicep/ARM templates, & drift detection.
• Establish cloud security posture management (CSPM) processes & remediation workflows for misconfigurations & policy violations.
• Design & implement DDoS protection, rate limiting, & bot mitigation controls at the network & application layers.

4. DevSecOps Pipeline & Automation

• Build & maintain security gates within CI/CD pipelines (Azure DevOps / GitHub Actions) — integrating security scanning, compliance checks, & automated approval workflows.
• Implement container security scanning (image vulnerability scanning, runtime security) for Docker & Kubernetes workloads.
• Automate security compliance checks & reporting against standards including ISO 27001, SOC 2, & GDPR using Azure Policy & custom automation.
• Establish security monitoring, alerting, & incident response pipelines using Azure Monitor, Microsoft Sentinel (SIEM), & Log Analytics.
• Define & test incident response runbooks for cloud & application security events, including breach containment & recovery procedures.

5. Governance, Compliance & Collaboration

• Conduct regular vulnerability assessments & penetration testing — managing external testing engagements & remediating findings.
• Provide technical security inputs for client due diligence, RFP responses, & compliance audit evidence (ISO 27001, SOC 2, GDPR, client-specific requirements).
• Work closely with the InfoSec Leader on aligning technical controls with the organisation's information security policy framework.
• Act as a security advisor & enabler to engineering teams — running secure design workshops, threat modelling sessions, & developer security awareness training.
• Maintain security documentation: architecture decision records, control evidence, risk registers, & remediation tracking.
