Graduate Cyber Security Engineer / Consultant.

About TrimTabs

TrimTabs Ltd is a pioneering technology company based in Bridgend, South Wales, focused on the sustainable, large-scale production of ultralong carbon nanotubes (CNTs) and hydrogen. Our patented technology transforms waste plastics and solvents into advanced materials with the potential to reshape energy, manufacturing and infrastructure.

We are rapidly scaling our operations and developing next-generation conductive wires, composites and building materials that outperform traditional materials while supporting a more sustainable future.

At TrimTabs, we value trust, discipline, curiosity, initiative and practical problem-solving. As a growing multidisciplinary team, we work collaboratively, think boldly and support one another to overcome challenges. Everyone contributes beyond the boundaries of a traditional job description, helping us turn breakthrough technology into real-world impact.

The Opportunity

TrimTabs is in the middle of a site transition, moving operations from one facility to another. The current estate spans both sites and mixes dynamic and static IP addressing, and the network carries manufacturing equipment as well as standard business IT.

The company needs someone to map the new network from the ground up, scope the options, help drive the migration itself, and make sure everything - including production equipment - is properly protected once it lands. It is a defined, high-ownership project with a clear beginning and end, and a rare chance to secure an operational technology environment rather than a purely office one.

What You Will Do

Network mapping and design

• Map the new network in full, including manufacturing equipment and the mix of dynamic and static IPs across the two sites
• Scope and compare a range of design options, setting out the trade-offs in cost, resilience and security so TrimTabs can make an informed decision
• Document the target-state architecture so it can be maintained after the project ends

Migration delivery

• Provide assistance on, and where appropriate leadership of, the project management of the migration between sites
• Coordinate with engineering, manufacturing and any external suppliers to sequence the move with minimal disruption to production
• Track risks, dependencies and cutover steps, and keep stakeholders updated on progress

Security testing and assurance

• Test the security of the new network, identifying weaknesses before and after cutover
• Ensure manufacturing equipment and operational technology are appropriately segmented and protected
• Recommend and, where practical, implement remediations, and leave behind clear guidance on ongoing monitoring and good practice for the team

What We Offer

• Hours: Minimum 25 hours per week; full-time placements considered
• Contract length: 6-month graduate placement
• Salary: At least the National Living Wage, with the potential for a higher salary at the discretion of the host business.
• Full ownership of a real, business-critical project with a visible outcome, rather than a rotation or a shadowing scheme
• Hands-on experience securing an operational technology environment alongside standard IT - a scarce and valuable specialism
• Direct access to a multidisciplinary team in materials science, chemical engineering and environmental technology
• The chance to build a specialist cyber security skill set while staying based in South Wales

Part of Tech Talent Cymru

This role is offered through Tech Talent Cymru, a graduate placement programme funded by Innovate UK and delivered by Darogan and Equal Education Partners. It connects talented graduates with Welsh SMEs working in frontier technology sectors.

On top of everything your host company offers, as a Tech Talent Cymru graduate you will receive:

• Dedicated training before your placement begins, so you start ready to make an impact
• Ongoing mentoring throughout your placement, from people outside your day-to-day team

Unless you choose to opt out, applying for this role also means you'll be considered for future opportunities on the Tech Talent Cymru programme - so one application could open more than one door.

Essential

• A degree in cyber security, computer science, networking, or a related STEM discipline
• A solid grounding in networking fundamentals: IP addressing, subnetting, DNS, DHCP, routing, switching, firewalls and VLANs
• Understanding of core security concepts - network segmentation, access control, vulnerability assessment and defence in depth
• Organised and methodical, comfortable documenting work and keeping a project moving
• Clear communication: able to explain risk and technical trade-offs to non-specialist colleagues and to senior decision-makers
• Self-starting and practical, happy to work hands-on across two sites in a small company
• Eligible to work in the UK and able to work on site in Bridgend and Neath

Desirable

• Exposure to operational technology, industrial control systems or manufacturing networks
• Experience with network mapping, discovery or monitoring tooling
• Familiarity with penetration testing or vulnerability scanning tools and methods
• Awareness of recognised frameworks such as Cyber Essentials, NIST CSF or ISO 27001
• Any project management or coordination experience, formal or informal
• Relevant certifications or progress towards them (for example CompTIA Network+ or Security+)
