Job Overview

This AI Security / GenAI role at IRIUM targets a Mid-Level (2–5 years) professional specializing in LLM security, cloud security, and AI governance. You will work across the full lifecycle of GenAI systems, from design to production, ensuring secure deployment of AI platforms, APIs, and agent-based systems. The ideal candidate blends security architecture expertise with a strong understanding of modern AI systems, especially around risk mitigation, compliance, and secure integration in enterprise environments.

🌍 Work Eligibility & Location

This role is anchored in Lisbon, Portugal with a Hybrid model, requiring partial on-site collaboration. While global candidates may apply, lack of explicit visa sponsorship suggests preference for candidates already authorized to work in the EU. This limits accessibility slightly but ensures faster hiring cycles and smoother onboarding for qualified applicants.

💰 Salary Intelligence

For a Mid-Level AI Security role in Lisbon, the estimated range of €45K–€65K aligns with market standards, especially for candidates combining cloud security and GenAI expertise. While not top-tier compensation globally, it remains competitive within Southern Europe, particularly when paired with benefits like training access and medical insurance. Candidates with niche experience in LLM security frameworks may negotiate toward the upper band.

📊 Role Breakdown

This role is structured around securing modern AI systems across multiple layers. Approximately 30% of your work will involve security architecture reviews, evaluating AI platforms, APIs, and integrations to ensure compliance with defined controls. Another 25% focuses on risk identification, including threats like prompt injection, jailbreaks, and data leakage in LLM-based systems.

Roughly 20% of your time will be dedicated to defining and enforcing guardrails for sensitive data usage, especially in regulated environments. You will also spend 15% collaborating with engineering and product security teams to validate implementations and enforce controls. The remaining 10% centers on governance contributions, including frameworks like OWASP Top 10 for LLMs, SAIF, and Model Context Protocol (MCP).

This is a highly cross-functional role requiring both technical depth and the ability to translate risk into actionable security requirements.

🧩 Required Skills & Fit

📈 Difficulty & Competitiveness

This role sits at the intersection of AI and security, making it inherently competitive despite being Mid-Level. The 2–5 years requirement is accessible, but the expectation of combining LLM knowledge with security architecture expertise significantly narrows the candidate pool. Applicants with hands-on exposure to GenAI risks and frameworks will stand out immediately.

🚀 Career Impact

This role offers strong career acceleration into one of the fastest-growing domains: AI security. You will gain hands-on experience with emerging frameworks and real-world GenAI risk mitigation, positioning yourself for high-value roles like AI Security Architect or AI Governance Lead. The exposure to enterprise AI deployments significantly boosts long-term market value.

📋 Key Responsibilities

You will support and review AI use cases from design through production, ensuring secure implementation of GenAI systems. Core tasks include defining security requirements for AI platforms, APIs, and agents, as well as conducting architecture and security reviews.

You will actively identify and mitigate risks such as prompt injection, data exposure, and model misuse, while implementing guardrails for sensitive data. Additionally, you will validate deployments, ensuring compliance with defined controls, and enforce logging, monitoring, and auditability.

Collaboration is critical, as you will work closely with engineering and product security teams to ensure secure AI adoption. You will also contribute to AI governance standards and frameworks like OWASP LLM Top 10 and SAIF.
