Junior Pre-Sales Engineer – Connectivity, Networking & Security

City of London – Hybrid (3 days on-site)

£40,000–£45,000 + Bonus

An exciting opportunity has arisen for a Junior Pre-Sales Engineer to join a fast-growing technology managed service provider in the City of London. This role is ideal for someone with a strong technical foundation in networking and connectivity who is eager to transition into a client-facing pre-sales position. You don’t need to already be in pre-sales – you may currently be in technical support, a NOC, or an engineering role and be looking for the chance to move into pre-sales and develop your commercial skill set.

You’ll gain hands-on exposure to technologies across connectivity, Wi-Fi, LAN, and security, with a particular focus on Fortinet and Cisco Meraki, while building confidence in demos, documentation, and customer presentations. This is a development-focused role with structured training, mentorship, and a clear career progression path.

What you’ll do

• Join customer meetings alongside Sales to support discovery, qualification, and solution development
• Support the sales team with scoping solutions, preparing proposals, and delivering demos
• Design and present technical solutions across connectivity, LAN/Wi-Fi, and security
• Produce technical documentation and support the creation of commercial proposals
• Translate customer needs into clear, scalable solutions aligned to the service portfolio
• Work closely with Sales, Delivery, and Product teams to ensure smooth handover from pre-sales to delivery
• Stay current with emerging technologies and best practices in networking and security

What I’m looking for

• Experience in a technical or customer-facing role (technical support, NOC, network engineering, or junior pre-sales)
• Solid understanding of IP networking and one or more of the following:
• LAN and Wi-Fi design/deployment
• Business internet and connectivity solutions
• Fortinet security (e.g., firewalls, SD-WAN)
• Cisco Meraki networking/security

What’s on offer

• Salary: £40,000–£45,000 + performance-based bonus
• Hybrid working (3 days in the office, 2 remote)
• Clear career path to becoming a fully-fledged Pre-Sales Engineer
• Structured training, mentorship, and support from senior colleagues
