Meta's Network Security team is seeking an experienced engineer to help secure our global Data Centers, network Backbone, Optical Infrastructure, and Edge PoPs. We do this by working extensively across the Meta family of products, including Instagram, WhatsApp, and AI where we identify and solve security problems across network infrastructure. You will be responsible for building, implementing, and operationally supporting the organization to develop security controls and services that will protect network infrastructure which helps serve traffic for over 3 billion users worldwide. We are looking for engineers with experience in managing complex issues that require problem-solving to drive security and innovation, who will research and develop new solutions to help protect our infrastructure and our users through a defense in-depth approach. The team thrives in finding security issues and eradicating them and makes life hard for bad actors. With focuses that range from large scale Distributed Denial of Service (DDoS), routing security, security tool development, defense against internal and external attacks there's lots of room to push your skill set in deploying network security controls at scale.


Network Security Engineer Responsibilities

  • Identifying risks across network infrastructure that would lead to the exposure of sensitive data, unauthorized access, or loss of availability and prioritizing remediation efforts to address gaps.
  • Influence security direction of the network, including management software and infrastructure to protect the network integrity of Meta platforms.
  • Conceptualize and lead efforts towards building sustainable and scalable network layer security controls and tooling.
  • Mentor and champion security practices through cross functional work with engineering teams throughout Meta.
  • Keep Meta's safe through active operation and defense of critical network infrastructure.


Minimum Qualifications

  • Engineering degree, or a related technical discipline, or equivalent work experience.
  • Experience coding in higher-level languages (e.g. Python, Rust, Go, C++).
  • Experience in configuration and maintenance of network platforms such as firewalls, routers, switches, load balancers, and proxies.
  • Experience learning software, frameworks and APIs.


Preferred Qualifications

  • Understanding of implementation and scaling of access controls across both host and network layers.
  • Understanding of threat models to better protect against attacks or detect new vectors.
  • Experience leading network efforts to investigate, prevent, and mitigate security incidents.
  • Experience evaluating and testing new vendor platforms and in house network initiatives for security issues.
  • Experience leveraging layered security models to defend critical network infrastructure.


About Meta

Now, Meta is moving beyond 2D screens toward immersive experiences like augmented and virtual reality to help build the next evolution in social technology. People who choose to build their careers by building with us at Meta help shape a future that will take us beyond what digital connection makes possible today-beyond the constraints of screens, the limits of distance, and even the rules of physics.

Where to Advertise Cyber Security Jobs in the UK (2026 Guide)

Advertising cyber security jobs in the UK requires a different approach to most technical hiring. The candidate pool is small, heavily vetted and in high demand across government, financial services, critical national infrastructure and the private sector simultaneously. Many of the strongest candidates hold active security clearances, are not actively job-searching through general platforms, and move primarily through specialist networks and trusted referrals. General job boards reach a broad audience but lack the specificity that security professionals expect. Specialist platforms, government-affiliated channels and cleared candidate networks each serve a different part of the market. This guide, published by CybersecurityJobs.tech, covers where to advertise cyber security roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

Cyber Security Jobs UK 2026: What to Expect Over the Next 3 Years

Cyber security is one of the few sectors where demand for talent has never once dipped. Every major technological shift of the past decade — cloud migration, remote working, AI adoption, the proliferation of connected devices — has expanded the attack surface that security professionals are expected to defend. And every expansion of that attack surface has generated more jobs. But the cyber security jobs market of 2026 is not simply a larger version of what it was three years ago. It is a structurally different market. The threats have evolved, the technologies used to combat them have changed, the regulatory environment has tightened considerably, and the roles being created reflect all of that. A job seeker who understands only the cyber security landscape of 2023 is already working with an outdated map. The candidates who will thrive over the next three years are those who understand where the sector is heading — which specialisms are attracting the most investment, which technologies are reshaping defensive and offensive security practice, and how the definition of a cyber security professional is broadening well beyond the traditional image of a network defender in a SOC. This article breaks down what the UK cyber security jobs market is likely to look like through to 2028 — covering the titles emerging right now, the technologies driving employer demand, the skills that will matter most, and how to position your career ahead of the curve.

Penetration Tester Jobs in the UK: What Employers Actually Want in 2026

The demand for skilled professionals in cyber security has never been higher, and penetration testers sit at the very heart of this rapidly evolving industry.

If you are considering a career in this field—or looking to advance within it—it is essential to understand what employers are really looking for in 2026. This guide breaks down the current expectations, required skills, certifications, and practical experience that can help you stand out in a competitive job market.
