London continues to be the centre of the UK’s tech infrastructure, and that’s especially true when it comes to graduate network engineer jobs. With more than 40% of the country’s tech companies headquartered in the capital, London offers graduates access to unparalleled opportunity.

From global telecom giants to unicorn startups, London is home to companies that build, operate, and secure the networks that keep everything connected. And for graduates eager to start their careers in networking, there’s no better place to find entry-level roles.

If you’re searching for graduate jobs in London with a focus on networking or IT infrastructure, you’re already looking in the right place.

Why London Is a Strong First Step for Networking Grads

London’s tech ecosystem is one of the most diverse in Europe, meaning graduates can enter roles across a wide range of sectors including telecommunications, financial services, public sector bodies, and enterprise IT. Here’s why it’s such an ideal first step for networking graduates:

Companies to Watch in London

London is full of standout employers who regularly hire graduate network engineers. Below are some companies and sectors worth watching (we’ve anonymised them for discretion):

1. Leading London Telco

One of the capital’s largest telecommunications providers, known for hiring junior network engineers into NOC and provisioning teams. They favour candidates with basic IP knowledge and Network+ or CCNA-level understanding.

2. Global Financial Services Firm

Offers roles for graduate network engineers in high-uptime environments. You’ll gain experience with low-latency networking, firewalls, and security tools. Often based in Canary Wharf with hybrid working.

3. Fast-Growth ISP

Headquartered in West London, this independent ISP has been rapidly expanding its fibre coverage. Graduate hires support field teams and core infrastructure, often rotating through departments.

4. Cloud & Hosting Provider

This central London firm offers graduates hands-on experience with hybrid cloud networks, virtualised environments, and SD-WAN. A great environment for those considering a future in DevOps or cloud engineering.

5. Multinational Managed Services Provider

Known for their graduate training programmes, especially for NOC Analyst and service desk roles. Strong focus on certifications and internal upskilling.

6. Data Centre Operator

If you’re curious about physical infrastructure, this operator offers junior roles maintaining network hardware, supporting BMS systems, and working closely with enterprise clients.

Typical Entry-Level Networking Roles

The path into networking often begins with titles that aren’t always clear at first glance. Here are some of the most common roles graduates secure when starting their network engineer jobs in London:

NOC Analyst (Network Operations Centre)

Often the starting point for many graduates, NOC Analysts monitor infrastructure health, raise tickets for incidents, and escalate issues to senior engineers. Expect shift work, but also rapid learning and deep exposure to how networks behave under real-world conditions.

Junior Network Engineer

This role blends hands-on technical tasks with learning opportunities. You might be configuring routers and switches, supporting infrastructure projects, or assisting with network upgrades and patching schedules.

Service Desk Analyst – Networking Focus

Sometimes labelled simply as "IT Support," these roles are ideal for building ticket management discipline, resolving first-line issues, and gaining foundational knowledge of network operations, often in customer-facing contexts.

Each of these titles sits within the broader category of entry-level network engineer jobs, and all offer routes into specialisms like network automation, cybersecurity, or cloud infrastructure.

Skills That Make You Competitive in London

Employers hiring junior network engineers look for a mix of technical capability, communication, and initiative. Here’s what will give you an edge:

Core Technical Skills

• IP addressing, subnetting, and routing basics (IPv4/IPv6)
• Familiarity with Cisco or Juniper CLI
• Ability to read network topologies and trace faults
• Awareness of firewalls, VPNs, DNS, DHCP
• Basic command-line or scripting skills (e.g. Python or Bash)

Tools & Platforms

• Wireshark for packet capture and analysis
• Remote access tools like PuTTY or SecureCRT
• Familiarity with service desk platforms (e.g. Jira, ServiceNow)
• Basic cloud exposure (AWS, Azure, or GCP preferred)

Soft Skills & Workplace Readiness

• Clear written and spoken communication
• Ability to explain technical concepts to non-technical people
• Time management and ticket hygiene
• Willingness to learn and adapt to new systems
• Professionalism in shift-based or 24/7 environments

Mastering these foundations early will support your move into higher-responsibility roles. The more you can show your grasp of real-world applications, the easier it will be to land your first network engineer job in London.

Certifications and Study Paths

Certifications can boost your credibility, especially when you're applying for entry-level network engineer jobs without much commercial experience. The right certification signals initiative and helps bridge the gap between university learning and real-world expectations.

Here’s a breakdown of where to start:

Most Useful Starter Certifications

CompTIA Network+

An ideal entry-level choice for those new to networking. It covers core protocols, troubleshooting, and network security basics and is often recognised by London employers.

Cisco Certified Network Associate (CCNA)

Widely regarded as the go-to certification for junior network engineer roles. It covers IP connectivity, switching, routing, and automation fundamentals. A must-have for roles in telcos, ISPs, and MSPs.

CompTIA Security+ (Optional)

If you’re leaning towards network security, this gives a well-rounded foundation on threats, defences, and compliance. Useful for roles in finance or public sector.

Where to Learn in London or Online

• Online Platforms: Try courses from Udemy, LinkedIn Learning, or Coursera. Many include practice labs or exam prep.
• In-Person Training Centres: Look at London providers like Firebrand, QA, or Learning Tree for accelerated courses.
• Free Labs & Sandboxes: Cisco Packet Tracer, GNS3, and Boson offer virtual environments for hands-on practice.

While certifications aren’t essential for all graduate jobs in London, they help hiring managers see your potential and show you’re serious about progressing in networking.

What Salaries Look Like in London

When considering graduate jobs in London, it’s important to have realistic expectations about starting salaries. London’s cost of living is higher than many other UK cities, but salary bands in networking reflect the level of demand for junior talent. 

Here’s what you can typically expect:

Entry-Level Salary Ranges

• NOC Analyst / 1st Line Support: £24,000 – £28,000 base salary
• Junior Network Engineer: £26,000 – £32,000 depending on certifications and location
• Service Desk Analyst (with networking exposure): £23,000 – £27,000

Salaries often increase after the first 12–18 months, especially if you pick up additional certifications or shift into more technical or client-facing roles.

Extra Pay Considerations

• Shift Allowances: NOC roles with 24/7 coverage can include evening or weekend premiums
• On-Call Pay: Some graduate roles include additional compensation for being on-call
• Contract Roles: While less common for true graduates, junior contractors can earn £150–£250/day, but without the same job security or benefits

How to Stand Out in a Competitive Market

With hundreds of applications for many graduate jobs in London, especially in tech and infrastructure, you need presence, positioning, and persistence. Here are our top tips for standing out:

Practical Tips for Getting Hired

• Tailor every application: Use keywords from the job description. Match your university projects, certifications, or part-time work to the role’s requirements.
• Use LinkedIn wisely: Optimise your profile with relevant skills, show you’re actively job-hunting, and follow companies hiring junior network engineers.
• Show initiative: Add value by sharing lab work, writing posts on what you’re learning, or joining networking communities like Cisco Learning Network.
• Apply beyond the obvious: Many smaller MSPs or consultancies don’t advertise widely. Look beyond big brand names with smaller businesses often moving faster in hiring.
• Partner with a specialist recruiter: Agencies that focus on networking jobs (like Hamilton Barnes) can give you direct access to roles, prep you for interviews, and match your goals to the right employer.
