Responsibilities

• Lead technical deep dives, tailored demos, and solution walkthroughs for enterprise security teams across the UK and Europe.
• Run structured technical discovery to understand customer security posture, existing tooling (SIEM, EDR, SOAR, identity), and integration needs.
• Design and validate customer-specific solutions that meet technical, security, compliance, and business requirements.

• Address technical objections and advise on best-practice deployment, rollout, and detection tuning strategies.
• Lead responses to security questionnaires, RFPs, and vendor risk reviews (SOC 2, ISO 27001, GDPR, HIPAA where relevant).
