Senior Security Engineer

AppliedAI is a pioneering AI technology company headquartered in Abu Dhabi, committed to innovation and excellence in artificial intelligence solutions in regulated industries such as healthcare, insurance, government, and financial services.

Opus is the world's first Knowledge Work AI platform
. Built by AppliedAI to pioneer Supervised Automation
, a human-in-the-loop model where AI handles repetitive, structured tasks while human experts provide crucial oversight at defined intervals.

The platform uses its proprietary Large Work Model to generate and orchestrate outcome-based workflows, enabling a dramatic reduction in the cost of knowledge work and allowing human talent to focus on high-value, creative, and judgement-intensive activities.

As a Senior Security Engineer you will play a pivotal role in designing and integrating security controls across cloud-native environments and AI-powered systems, ensuring that secure-by-design principles are embedded throughout the software development lifecycle.

The successful candidate will help define, pilot, and implement system architectures that support our reimagined information security vision, with the objective of automating security processes at scale across the design, development, and operational phases of solution delivery.

Working collaboratively across the broader information security organisation, spanning the first, second, and third lines of defence, the role will drive the delivery of agentic security capabilities and solutions aligned with our target operating model.

• Conduct security assessments, threat hunts, code and logs reviews, and penetration testing to identify vulnerabilities in our applications, and drive continuous monitoring improvements.
• Design, implement, optimize, and monitor security controls and tooling from the ground up, strengthening security across endpoints, infrastructure, and application CI/CD pipelines.
• Own incident response for security events, from detection through containment, remediation, and post-incident review.
• Collaborate with engineering teams to raise the security bar through reviews, guidance, embedding security across SDLC and automation.
• Join customer-facing technical and security discussions where needed, acting as a trusted security point of contact.
• Support compliance initiatives and customer security requirements, including SOC 2, ISO 27001, ISO 42001, GDPR, HIPAA, and emerging AI regulations.

• At least 7 years experience within information security, ideally with a hands-on background in application or infrastructure security
• Solid understanding of core security principles and architectures
• Hands-on experience building, testing and deploying security solutions that automate complex processes
• Cloud platform experience (AWS, Azure, or GCP), including securing cloud-native infrastructure and services
• Working knowledge of core security tool categories: SIEM, vulnerability management, IAM, SAST/DAST
• Scripting or programming proficiency (Python preferred) for building automation and security tooling
• Experience of embedding security within the SDLC
• Exposure to AI and agentic systems (practical or conceptual), including:
• Security and governance for AI Solutions (Identity, observability, risks)
• Agentic Architecture and patterns (MCP, RAG, Tools, Memory, Harnesses)
• Experience working in complex, enterprise-scale environments
• Ability to translate security requirements into engineering-aligned solutions
• Solid grounding in network security fundamentals (TCP/IP, DNS, routing)
• Relevant certifications are a plus (e.g. CISSP, OSCP, CCSP, GIAC), though hands-on track record matters more than credentials
• Opportunity to work with a highly innovative AI technology company.
• Collaborative and innovative work environment.
• Growing, entrepreneurial and forward-thinking culture.
• Career growth and professional development opportunities.
• Exposure to a thriving ecosystem working from our Abu Dhabi HQ.
