Conduct investigations and analysis to identify, contain, and remediate cybersecurity threats and incidents.

Support security assessments, audits, and compliance activities by providing operational security expertise and evidence as required.

Assist in evaluating, implementing, and maintaining security technologies and capabilities to strengthen the organization’s security posture.

Contribute to security awareness and knowledge-sharing initiatives across technology teams and business stakeholders.

Mentor junior team members and provide guidance on security processes, technologies, and best practices.

Participate in on-call and incident response activities as required to support business continuity and operational objectives.

How do we define success for your role?

You demonstrate BDO's core values through all aspect of your work: Integrity, Respect and Collaboration
You understand our client’s industry, challenges, and opportunities; clients describe you as positive, professional, and delivering high-quality work
You identify, recommend, and are focused on effective service delivery to our clients
You share in an inclusive and engaging work environment that develops, retains, and attracts talent
You actively participate in the adoption of digital tools and strategies to drive an innovative workplace
You grow your expertise through learning and professional development

Qualifications & Requirements

Degree in Cybersecurity, Information Technology, Computer Science, Engineering, or a related field, or equivalent education and experience.

5+ years of progressive experience in cybersecurity, with a focus on security operations, incident response, threat detection, or cyber defense.

Total rewards that matter: We pay for performance with competitive total cash compensation that recognizes and rewards your contribution. We provide comprehensive benefits from day one, and a flexible personal time off policy. We’re committed to supporting your overall wellbeing and provide reimbursement for wellness initiatives that fit your lifestyle.

Everyone counts: We are committed to creating a workplace where employees can participate fully, contribute meaningfully and succeed without barriers.

Our commitment extends to ensuring that our application process is both inclusive and accessible. If you require accommodation to complete the application process, please contact us.

Flexibility: All BDO personnel are expected to spend some of their time working in the office, at the client site, and virtually unless accommodations or alternative work arrangements are in place.

Our model is a blended approach designed to support the flexible needs of our people, the firm and our clients. It’s about creating work experiences that meet everyone’s needs and providing flexibility to adjust when, where and how we work to meet the expectations of our role.

Code of Conduct: Our Code of Conduct sets clear standards for how we conduct business. It reflects our shared values and commitments and includes guiding principles to help us make ethical decisions and maintain trust with each other, our clients, and the public.
