Market National Security & Defense

At Jacobs, we're challenging today to reinvent tomorrow by solving the world's most critical problems for thriving cities, resilient environments, mission-critical outcomes, operational advancement, scientific discovery and cutting-edge manufacturing, turning abstract ideas into realities that transform the world for good.

Your impact

Join our growing Cyber Security team delivering high-impact work across large-scale critical national infrastructure projects. In this role, you’ll help organisations protect essential services by shaping secure, resilient IT environments that underpin sectors such as energy, water, environment, transport, and defence.

What you’ll do

You’ll lead cyber security activities across client engagements, combining hands-on delivery with strategic advisory. Acting as a trusted partner to clients, you’ll guide the design and implementation of secure solutions while ensuring alignment with business needs and regulatory expectations.

You’ll play a visible role in client engagement, including pre-sales and helping shape opportunities from a cyber perspective. Internally, you’ll collaborate with multidisciplinary teams, contribute to project leadership, and support the development of others - bringing a proactive, solutions-focused mindset to everything you do.

This is a role for someone who is comfortable operating across governance, engineering, and assurance - able to move between detail and big-picture thinking while inspiring confidence in clients and colleagues alike.

Here's what you'll need

We’re looking for an experienced cyber security professional with a strong foundation in IT security and a track record of delivering in complex environments. You’ll bring credibility, confidence, and a collaborative approach to working with clients and teams.

•Proven solid experience in cyber security within IT infrastructure or complex enterprise environments

•Strong technical understanding across infrastructure, networks, cloud, and security domains

•Experience leading or contributing to client engagements, including pre-sales or shaping solutions

•Ability to balance hands-on delivery with governance, assurance, and stakeholder engagement

•Excellent communication skills, with the ability to build trust and influence at all levels

•Experience mentoring or leading others within project environments

At Jacobs, we deliver solutions that matter. You’ll be trusted to make technical decisions, encouraged to challenge respectfully, and supported to deliver pragmatic, high-quality solutions. If you’re ready to play a leading role in securing critical systems and shaping the future of cyber resilience, we’d love to hear from you.
