Overview

Profile match
Darktrace is a British cybersecurity company founded in Cambridge in 2013 by mathematicians and former government intelligence staff, built on the idea that a network can be defended by learning its own normal behaviour rather than matching known attack signatures. Its Self-Learning AI builds a live model of how each user, device and workload usually behaves, flags deviations that no signature would catch, and can act autonomously to contain an intrusion in progress. The company listed in London in 2021 and was taken private by Thoma Bravo in 2024 for around five billion dollars, and it protects networks, email, cloud and operational technology for thousands of organisations.

Darktrace is a global leader in AI-driven cybersecurity, helping organizations stay ahead of evolving threats every day.

Darktrace was built on a genuinely differentiated idea: that Adaptive AI could detect and respond to novel, real-time cyber threats. That approach matters more than ever in the era of AI. Today, our customers depend on us to stay ahead.

At Darktrace, we are energized by that responsibility. We work across teams and rally around a shared goal. We own outcomes end to end - step in, step up and see things through without waiting to be asked. We make decisions with urgency, say the hard thing, and hold each other to high standards with care and directness. We move first and learn fast anticipating where our customers are going next, continuously challenging ourselves.

We invest in the skills, learning and opportunities that help people deliver at the level their roles demand, and reward the aptitude and curiosity to grow beyond them.

Our Values: Own It | Win as One | Raise Our Bar | Move First. Learn Fast

Job Description:

Following the rapidly continued growth of our customer base, Darktrace are looking to add to our post-sales team of Cyber Security Infrastructure Engineers.

As a Senior Cyber Security Infrastructure Engineer in the Professional Services organisation, you will ensure Darktrace is deployed, integrated, and optimized to the highest standards providing our clients with industry-leading, AI-powered, cyber security protection.

This crucial, fast paced role involves discussing, proposing, and implementing robust solution architectures for complex deployments across all coverage areas. You will be assisting customers with deploying Darktrace technology within network, cloud, OT, and email environments as well as leading and becoming a trusted advisor to key customers in their security infrastructure design and planning.

What will I be doing:

You will be regularly completing deployment projects on or before expected Service Level Objectives (SLOs) and integrating new systems into existing network architecture. On the support side, you'll efficiently manage customer support tickets to assist with technical issues and proactively engage with customers to help maintain a healthy deployment.

In this position you'll be maintaining and enhancing communication between all go-to-market teams, including sales, customer success, and operations. At times you will also be providing guidance and mentorship to junior team members.

What experience do I need:

We welcome applications from experienced technical candidates with demonstrated experience in implementing cyber defense tools and protecting networks against security threats. You'll also hold the strong ability to collaborate with internal and external stakeholders (including mentorship of other technical resources). On a technical level, you'll ideally have the following experience:

  • A technical educational background and experience working in a similar post-sales role,
  • Advanced knowledge of computer networking protocols, LAN and WAN, cyber security principles, and the OSI reference model,
  • A broad understanding of network and cloud architecture design, configurations, principles, and best practices,
  • Proficiency in OT network principles and practices based on the Purdue model,
  • Advanced level knowledge and/or certifications with industry-standard vendors such as AWS, Microsoft, Cisco, and Palo Alto Networks.
  • Fluency in an additional European language is desirable but not essential.

Additionally, it would be helpful if you had experience in implementing Darktrace sensors and software modules into various environments (including cloud, email, and OT) as well as experience with Darktrace deployment options, integrations, and response enablement and tuning (custom routes, firewall integrations, email) but this is not a requirement for the role.

As a growing business strengthening its governance and controls, this role plays a part in supporting high standards of integrity and accountability.
