Senior Marketing Executive : B2B tech marketing

deltaflare is the UK's specialist in Operational Technology (OT) cybersecurity for Critical National Infrastructure (CNI) operators. We deliver NIS2 and CAF compliant protection across gas, electricity, water, renewable technology and transport networks — the systems that keep the country running.

We work where IT meets industrial reality: inside control rooms, substations and treatment works, helping CNI operators navigate the unique challenges of securing hyper-connected physical systems without disrupting the operations that millions of people depend on.

OUR MISSION

To enable the safe and cyber secure operation of hyper-connected industrial systems.

OUR VISION

A world where essential services can deliver digital transformation with confidence, built on a solid cyber-physical security foundation.

OUR VALUES

We innovate with purpose, focusing on solutions that can be adopted safely and at scale.

ABOUT THE ROLE

As Senior Marketing Executive, Campaigns and Demand, you’ll run deltaflare’s campaigns end to end: regulatory content launches, events, roundtables, webinars, speaking, awards and podcasts, partner acquisition and joint partner activity, email and our LinkedIn channel. You’ll get our content and events in front of a small, named group of senior engineers, security leaders and operations directors at UK gas and water network operators, with electricity and transport next, where every conversation counts.

You’ll work to a comprehensive marketing calendar for the year, agreed with the Head of Marketing, and deliver your part of it within an agreed plan and budget. You’ll also help evolve it, proactively proposing new activity and changes to what is planned, based on results and in line with our commercial objectives.

You will report directly to the Head of Marketing, based in Richmond. You’ll work as one team with the Senior Marketing Executive, Content and Product Marketing, who creates the content you launch and promote, alongside our sales account owners and partners. Partners are a preferred route to market: the Head of Marketing leads the partner programme, and you’ll support recruiting and enabling them.

This is a level 2 role with real ownership. You’ll own the results of the event programme and partner acquisition activity, commit spend within agreed budget lines, and keep HubSpot and the calendar up to date so every conversation with a target account is captured and followed up.
