Cybersecurity Intern – AI & SaaS Systems
Remote | Duration: 6 Months
Start Date: 26 February 2026
Commitment: ~20 hours per week
Eligibility: Students enrolled in a credit-bearing placement
Application Deadline: 9 February 2026
Compensation: Unpaid (credit-bearing, contributing towards your degree)
About the Opportunity
NexCell Solutions is offering a 6-month Cybersecurity Internship for students seeking hands-on experience in the security, resilience, and protection of modern AI-driven and SaaS-based systems.
This role operates at the intersection of cybersecurity engineering, cloud infrastructure security, encryption, and risk management. You will support efforts to identify vulnerabilities, harden systems, and enforce security-by-design principles across real production environments.
Your work will directly support live internal systems, real security controls, and real risk-mitigation processes within a technology consultancy operating at enterprise standards. This is not simulated coursework or theoretical lab work.
This internship is designed for students who want a serious cybersecurity foundation, with exposure to how security is implemented, monitored, and governed in real AI and SaaS businesses.
Responsibilities
Support identification and assessment of security risks across cloud-based systems
Assist with vulnerability scanning, threat modelling, and attack-surface analysis
Review authentication, authorisation, and identity-management flows
Support implementation and review of encryption at rest and in transit
Assist with secrets management, key-handling practices, and secure configuration reviews
Support least-privilege access models and role-based access control (RBAC)
Monitor logs, alerts, and security events for anomalies or suspicious behaviour
Assist with security hardening tasks across applications and infrastructure
Contribute to internal security documentation, guidelines, and incident procedures
Support compliance-aligned security practices (GDPR-aware controls, audit readiness)
Learn how DevSecOps and secure development practices operate in production
Escalate potential risks clearly and responsibly
Collaborate with developers, system architects, and senior technical leads
You will be expected to think critically, document clearly, and act with a professional, security-first mindset.
Ideal Candidate
Academic Requirements:
Currently enrolled in a Bachelor's or Master's degree that allows a credit-bearing internship
Studying Cybersecurity, Computer Science, Information Security, IT, Software Engineering, or related disciplines
Professional Attributes:
Interested in cybersecurity within AI, SaaS, and cloud-native systems
Seeking exposure to real security engineering challenges beyond academic coursework
Comfortable working remotely and managing time independently
Able to communicate clearly in written English and operate professionally
Required Skills & Knowledge
Core Cybersecurity Foundations
Strong understanding of the CIA triad (confidentiality, integrity, availability)
Solid familiarity with OWASP Top 10 (Web & API)
Understanding of threat modelling concepts (e.g. STRIDE or similar)
Ability to reason about attack surfaces and system risk, not just isolated vulnerabilities
Security-first mindset with attention to misconfiguration risks
Encryption & Cryptography
Strong understanding of modern encryption standards (AES-256, RSA, Elliptic Curve cryptography)
Clear understanding of encryption at rest vs encryption in transit
Familiarity with TLS 1.2 / TLS 1.3 and certificate-based security
Understanding of hashing vs encryption (e.g. SHA-256, bcrypt, Argon2)
Awareness of key-management principles (secure storage, key rotation, environment isolation)
Awareness of common cryptographic mistakes (hardcoded secrets, weak hashes, key reuse)
Identity, Access & Authentication
Understanding of OAuth 2.0 and token-based authentication flows
Knowledge of JWT structure and common security pitfalls
Multi-factor authentication principles
Role-Based Access Control (RBAC) and least-privilege enforcement
Session management and access expiry awareness
Cloud & Infrastructure Security
Understanding of cloud shared responsibility models
Awareness of cloud security concepts (AWS, GCP, or Azure): identity and access management, secure storage access controls
Basic understanding of container isolation (Docker-level knowledge)
Network security fundamentals (firewalls, ports, TLS, secure API exposure)
Security Testing, Monitoring & Tooling
Exposure to vulnerability scanning or security testing tools (e.g. OWASP ZAP, Burp Suite, Snyk)
Understanding of dependency and supply-chain security risks
Familiarity with Git-based workflows and secure pull-request practices
Awareness of log monitoring and security event concepts
Basic incident response awareness (detection, escalation, containment)
Preferred Skills
Exposure to DevSecOps or secure CI/CD pipelines
Basic scripting skills (Python or Bash) for security tasks
API security testing experience
Prior CTFs, labs, or security research
Interest in security challenges related to AI systems and data protection
