Description

We are seeking an enthusiastic and passionate professional for a Senior Cloud, AI & Data Security Engineer role who wants to design and implement security solutions for systems and services across AWS, Azure, and AI/ML platforms. We need someone who can establish the highest standards that meet and exceed security governance solutions and practices, provide assurance to management and auditors, and ensure sustained protection by embedding controls in operational and DevOps (CI/CD) practices with a focus on automation.

We are looking for someone who has a high level of technical security expertise and who takes seriously the responsibility of monitoring, detecting, protecting, and maintaining the security of data, AI/ML systems, cloud platforms, and networks.

You are a leader with a strong technical background. You have demonstrated strength in:

• Developing and implementing secure cloud and AI/ML architectures using a risk-based cybersecurity and data privacy strategy
• Defining security patterns, roadmaps, and operating models that leverage collaboration
• Facilitating industry-standard information security governance
• Advising senior leadership on cybersecurity, AI risk, and privacy risks, threats, and investment strategies
• Documenting appropriate policies and procedures to manage information security risks, including those unique to AI/ML systems and sensitive data assets

As a qualified candidate, you will be part of the team driving BMO's Cloud, AI, and Data Security implementation. As a member of this team, you should possess the ability to inspire yourself and all of our team. Based on your previous experiences, you will inject new knowledge and skills into an already high-performing team, thus elevating our efforts to new heights.
