Scandinavian Software Park

Overview of job

Scandinavian Software Park is the Hanoi-based tech hub and home to several of Scandinavia’s market-leading B2B SaaS companies. Founded and operated by Monterro, the leading B2B software investor in the Nordics, Scandinavian Software Park enables portfolio companies to accelerate growth and build high-end engineering and product capabilities in Vietnam. This role sits within our product services, aiming to delivering expert-level services directly to Monterro’s portfolio of 30+ B2B software companies.

This is a senior individual contributor role for a seasoned security professional who brings deep offensive and defensive expertise and can operate independently across multiple complex engagements. As a Cyber Security Specialist, you will be a key technical authority, leading continuous vulnerability intelligence operations, conducting advanced penetration tests and code security reviews, and advising on the security of AI-powered features across Monterro’s portfolio of Nordic B2B SaaS products. You are also expected to bring the judgment and seniority to triage ambiguous findings, lead threat modeling sessions, support incident response and raise the security maturity of the products you work with.

What you’ll do

Penetration Testing

• Map the environment of each portfolio company, including LLMs, prompts, RAG pipelines, agentic workflows, APIs and connected systems, to define a precise attack surface before testing begins.
• Plan and execute full-scope penetration tests against web applications, APIs, and internal systems for portfolio companies, from scoping and reconnaissance through to exploitation and reporting.
• Stress-test system behavior under real-world adversarial conditions, evaluating how models and agents respond to manipulation, privilege abuse, and unexpected inputs.

Red Teaming

• Conduct threat intelligence-led OSINT reconnaissance to map each portfolio company’s digital footprint, identify exposed assets, and define realistic attack scenarios grounded in how real adversaries operate.
• Execute multi-vector attack simulations combining external and internal network exploitation, social engineering, phishing, and lateral movement to reveal how far an attacker could realistically penetrate.
• Run both Full Simulation engagements (end-to-end attack chain from initial access to exfiltration) and Assumed Compromise scenarios (focused on lateral movement and detection/response after access).
• Validate detection and response capabilities: evaluate whether security controls, monitoring, and incident response processes would catch and contain a real attack.

Code-Based Security Review

• Lead in-depth security reviews of application codebases, identifying logic flaws, injection vulnerabilities, broken authentication, insecure data handling and supply-chain risks.
• Apply AI-assisted static analysis alongside manual review techniques to achieve deeper coverage across multiple languages and frameworks.
• Delivery findings with severity ratings, exploitability assessments and precise remediation guidance; present results directly to engineering leads and CTOs.

Threat Modeling

• Lead threat modeling sessions (STRIDE, PASTA, or equivalent) with portfolio company product and engineering teams during design and architecture phases, not just after the fact.
• Translate threat models into actionable security requirements, test cases, and backlog items that engineering teams can act on.
• Build and maintain threat profiles for portfolio companies, updating them as products evolve and new attack surfaces emerge.

System Security

• Assess the security of AI-powered product features – covering prompt injections, indirect prompt injection, model data leakage, insecure LLM integrations and adversarial input scenarios.
• Stay current on the evolving AI threat landscape (OWASP LLM Top 10, emerging jailbreak patterns, supply-chain risks in AI frameworks) and translate findings into practical guidance.
