Job description

Overview

Sales Engineer ( presales network engineer )

We're looking for an experienced Sales Engineer to join a growing team in London, supporting presales, solution consultants, and sales teams across a wide range of solution designs. The focus will be on networks, SD-WAN, SASE, and cyber security, but the role also offers the chance to expand your expertise across other areas of IT solutions.

This is a highly collaborative position that bridges the gap between commercial and technical functions. From the early stages of the sales cycle, you'll act as a trusted advisor—helping to qualify opportunities, craft innovative solution designs, and ensure proposals are both technically robust and commercially compelling. You'll play a hands-on role in presenting solutions to customers, delivering product demonstrations, and remaining a key point of contact throughout the solution lifecycle.

Responsibilities

• Support presales activities, solution consultants, and sales teams across a range of solution designs with a focus on networks, SD-WAN, SASE, and cyber security.
• Qualify opportunities early in the sales cycle and craft innovative technical and commercial solution designs.
• Present solutions to customers, deliver product demonstrations, and be a key point of contact throughout the solution lifecycle.

Qualifications

• Strong technical depth with the ability to communicate clearly with both technical and non-technical audiences.
• Solid understanding of networking principles and protocols (TCP/IP, OSPF, BGP, VRRP, firewalls, IPSec, SIEM, wireless).
• Experience in at least two key solution areas such as networks, cloud, security, or unified communications.
• Familiarity with SD-WAN and SASE technologies, cloud architectures, and relevant certifications would be an advantage.
• Energetic, commercially aware, and eager to become a subject-matter expert; strong organisational skills and the ability to manage multiple projects in a fast-paced environment.

Role details

• Hybrid role with 2 or 3 days a week in the office ( London).
