The Role You will take ownership of SOC-aligned platform engineering across the full lifecycle—from customer onboarding and solution design through to optimisation, maintenance, and continual improvement. You’ll work closely with internal teams and customers to ensure security platforms are resilient, efficient, and aligned to evolving threat landscapes. A key part of the role is leading complex deployments and providing technical direction across SIEM, EDR, SOAR, and supporting technologies.

You’ll oversee platform health through proactive lifecycle management, including patching, upgrades, and service transitions, while driving improvements in detection, automation, and performance. You’ll also act as a senior escalation point, mentoring engineers and helping to build capability across the team. Alongside delivery, you’ll contribute to pre-sales activities, shaping solutions and supporting bids, demos, and customer discussions.

How You Work You’re a confident communicator who can translate complex technical concepts into clear, actionable insights for both technical and non-technical audiences. You’re comfortable leading engineering delivery, making decisions under pressure, and balancing customer needs with operational constraints. You thrive in collaborative environments, working closely with SOC analysts, detection engineers, sales teams, and optimisation specialists to deliver effective security outcomes.
