Network Security Lead

Company: Accenture

Location: London

Posted: April 29th, 2026

Accenture is looking for an exceptional Network Security Lead to join our Network Infrastructure Engineering practice. This is a senior individual contributor and client leadership role for someone who combines deep enterprise network security expertise with the commercial instinct and communication skills to win trust at the highest levels of a client organisation.

You will be the go-to security authority within the network practice — the person clients call when they need to understand how to modernise their security architecture, navigate a compliance challenge, or respond to an evolving threat landscape. You will own relationships with a portfolio of blue-chip enterprise clients, guiding them on their journey toward Zero Trust, SASE, and SSE adoption, whilst shaping and delivering the work that follows.

This role demands someone who is equally comfortable whiteboarding a ZTNA architecture with a room full of CCIEs, presenting a business case to a CISO, and rolling up their sleeves to produce the proposal, design, or deliverable that gets the deal done. Versatility is not optional — it is the role.

Qualifications

The Ideal Candidate

You are not a pure architect who hands off to others, nor a pure account manager who relies on technical colleagues to fill the gaps. You occupy a rare middle ground — someone who has earned their stripes technically and subsequently developed the judgement, communication skills, and commercial instincts to lead at a strategic level.

You are energised by variety. One day you are presenting a Zero Trust roadmap to a financial services CISO; the next you are deep in a proposal for a global manufacturing client's SASE migration; the following week you are in a workshop facilitating a threat modelling exercise with a team of network engineers. You do not just direct — you do.

You understand that AI is a tool, not a replacement for expertise, and you use it intelligently to move faster and produce better work — without compromising quality or accuracy.

Most importantly, you genuinely care about helping clients improve their security posture, meet their compliance obligations, and protect what matters most to their business.
